When selecting natural wood flooring for your home or commercial space, a critical decision is choosing between engineered and solid hardwood flooring. Both options offer premium, natural wood with the same classic aesthetic and warmth but differ in structural composition and performance. This article will discuss the fundamental differences between engineered and solid hardwood flooring—including their applications, durability, upkeep, and environmental effects.
Construction and Composition The primary difference between solid hardwood and engineered wood lies in their construction. Solid hardwood is made from a single piece of wood, typically about ¾ inch thick, and is milled from a single piece of timber. This straightforward construction makes solid hardwood flooring durable and allows it to be sanded and refinished multiple times over its lifespan.
In comparison, engineered wood consists of multiple layers. The top layer, known as the wear layer, is a thin layer of natural wood that varies in thickness. Beneath the wear layer, several plywood layers are stacked and bonded together in a cross-grain configuration. This layered construction enhances dimensional stability, making it less likely to warp and shrink than solid hardwood.
Applications Solid wood flooring can be installed above-grade or on-grade but is not recommended for below-grade environments. This limitation is due to moisture, as solid wood is more susceptible to moisture. Below-grade spaces, such as basements, often have higher humidity levels and are prone to moisture infiltration from the surrounding soil. If the soil level along any perimeter wall is more than 3 inches above the installed flooring, the risk of moisture damage increases significantly. This makes solid wood flooring less stable and more vulnerable in such conditions.
On the other hand, engineered wood flooring is designed to be more dimensionally stable and moisture-resistant. This makes it suitable for installation above, on, or even below grade. The cross-laminated structure of engineered wood contributes to its resistance to moisture. The plywood or HDF layers are less susceptible to water damage than solid wood, which can swell or warp when exposed to moisture. Additionally, the adhesives used in engineered wood flooring are typically formulated to resist moisture, further enhancing the floor’s durability. This makes engineered wood a suitable option for areas where moisture is a concern, such as basements (below grade) or over concrete slabs.
Durability and Longevity Solid hardwood and engineered wood each have their own strengths in durability and longevity. Solid hardwood is recognized for its long lifespan; with proper care, it can last for decades. As a solid piece of timber, it can be sanded and refinished multiple times, which is a significant advantage if the floor gets scratched or the owner wishes to change the finish.
Engineered wood, while also durable, has a different set of strengths. Its multi-layered construction provides greater resistance to temperature and humidity changes, reducing the risk of warping or cupping. This stability makes engineered wood an excellent choice for environments where solid hardwood might struggle, such as in rooms with fluctuating humidity levels or below-grade installations.

Maintenance and Care Both engineered and solid hardwood floors require regular upkeep to stay in top condition. This includes regular sweeping or vacuuming to remove dirt and debris that can scratch the surface and occasional damp mopping with a cleaner designed for wood floors.
Solid hardwood floors may require more maintenance, mainly if installed in high-traffic areas. The ability to sand and refinish solid wood multiple times offers the opportunity to restore the floor’s original beauty after years of wear and tear.
Engineered wood, while generally easier to maintain due to its resistance to environmental changes, may need to be replaced sooner if the wear layer is damaged. However, higher-quality engineered wood with a thicker veneer can be refinished, extending its lifespan significantly.
Environmental Impact Both engineered and solid hardwood have their pros and cons in terms of environmental impact. Solid hardwood, especially from responsibly managed forests, can be a sustainable choice due to its natural, renewable material. However, producing solid wood flooring consumes more of the tree, which can lead to higher wastage. Engineered wood is designed to maximize the use of each tree, as the veneer is much thinner than a solid wood plank. This efficient use of resources makes engineered wood a more sustainable option in many cases. Additionally, many engineered wood products are now available with eco-friendly finishes and adhesives that reduce the emission of volatile organic compounds (VOCs), making them a healthier choice for indoor air quality.
Making the Right Choice Choosing between engineered and solid hardwood flooring ultimately comes down to understanding your space’s specific needs and weighing each option’s benefits and drawbacks. Solid hardwood offers timeless appeal, longevity, and the ability to be refinished multiple times, making it an excellent investment for the long-term. Engineered wood, with its enhanced stability, is ideal for environments where solid wood might not perform well.
By considering factors such as application requirements, environmental conditions, and maintenance preferences, you can select the flooring option that best suits your lifestyle and design goals. Whether you opt for the classic charm of solid hardwood or the modern versatility of engineered wood, both options offer beauty and value that can enhance the warmth and character of any space.

Architectural design is constantly evolving, striving to integrate and find balance between aesthetic and functional elements. One of the key components gaining traction in modern facade design is the use of slats. Slats, typically used as walls, are wood panels installed parallel to each other and spaced to allow light and air to pass through. However, when combined with other adjacent materials, slats can also function as decorative enclosures.
Slats, or louvers, have become integral in contemporary architecture, offering a blend of visual appeal, energy efficiency, and environmental harmony. This article touches on the multifaceted role of slats in architectural facades, highlighting their benefits, applications, and the innovative ways architects utilize them.
Aesthetically Appealing and Visually Dynamic Slats offer an unparalleled aesthetic versatility that can transform the appearance of a building. They can be designed to fit various architectural styles—from minimalist modern to rustic traditional. The arrangement of slats can create dynamic patterns and shadows, adding depth and texture to a building’s exterior. Whether installed horizontally, vertically, or diagonally, slats can make a facade visually striking, breaking the monotony of plain surfaces.
Plus, slats can be customized to achieve different levels of transparency and opacity. This adaptability allows architects to play with light and shadow, creating a facade that changes appearance throughout the day. The interplay of sunlight with the slats can produce a living, breathing building exterior that interacts with its environment in a visually captivating manner.
Environmental and Energy Efficiency In addition to their aesthetic benefits, slats contribute significantly to a building’s environmental performance. They act as sunshades, controlling the amount of sunlight that enters a building. By reducing direct solar gain, slats help in minimizing the need for artificial cooling, thus lowering energy consumption. This passive cooling strategy is particularly beneficial in hot climates, where managing heat intake is crucial for maintaining comfortable indoor temperatures.
Slats can also be designed to facilitate natural ventilation. By allowing air to flow through the facade, they help in maintaining indoor air quality and reduces reliance on mechanical ventilation systems. This not only enhances the building’s energy efficiency but also promotes a healthier living environment for occupants.
Privacy Privacy is a critical consideration in architectural design, especially in urban settings where buildings are often closely spaced. Slats offer a practical solution for maintaining privacy without sacrificing light or ventilation. By strategically spacing and angling the slats, architects can prevent direct lines of sight into the building while still allowing natural light to permeate the interior.
The use of slats in architectural facade design epitomizes the blend of form and function that defines modern architecture. Their ability to enhance aesthetics, improve energy efficiency, provide privacy, and adapt to innovative applications makes them a valuable tool for architects. As architectural design continues to evolve, the role of slats in creating sustainable, functional, and visually engaging buildings is likely to expand, driving forward the future of urban landscapes.

Architecture and design trends have evolved and expanded over centuries, yet some techniques stand the test of time. One such enduring method is Shou Sugi Ban, a traditional Japanese wood charring technique that has long captivated designers and architects worldwide.
The History and Philosophy of Shou Sugi Ban Originating in Japan in the 18th century, Shou Sugi Ban, also known as Yakisugi, is a wood preservation technique that chars the surface of dimensional lumber, such as cladding, to enhance its durability and aesthetic appeal. Historically, this technique was used to protect wooden buildings from weathering, pests, and fire. The process involves burning the wood, cooling it, cleaning off the soot, and finishing it with natural oils. The result is a strikingly beautiful, carbon-rich surface that is durable and resistant to decay.
The philosophy behind Shou Sugi Ban aligns with the Japanese aesthetic principle of wabi-sabi, which finds beauty in imperfection and transience. Wabi-sabi is an ancient Japanese worldview centered on accepting the imperfect and transient nature of all things. It values simplicity, asymmetry, and the natural processes of growth and decay. In the context of Shou Sugi Ban, this philosophy manifests through the charred wood’s unique textures and variations, highlighting the material’s raw and unrefined beauty.
The Science Behind Shou Sugi Ban Shou Sugi Ban is often viewed as a cultural relic, yet it is much more than just the simple technique of charring the exterior of wood. The charring process leads to the carbonization of surfaces, transforming the outer layer of wood into a protective layer.
Carbonization Limits Food Sources for Pests and Microorganisms
Fungal Resistance: The charring process creates a carbon layer that makes the wood less hospitable to fungi and other decay organisms. The high heat alters the organic compounds in the wood, making it more difficult for these organisms to break down the wood fibers.
Insect Deterrence: Termites and other wood-boring insects are less likely to infest charred wood. The carbonized surface is not only harder for these pests to penetrate and less appealing as a food source, thus preventing infestations that can significantly reduce the lifespan of untreated wood.
Carbon Layer Establishes a Barrier Against Nature’s Elements
Moisture Barrier: Charring the wood closes its pores, significantly reducing its ability to absorb water. This water-resistant barrier prevents common issues such as warping, swelling, and splitting caused by moisture infiltration and subsequent drying cycles.
UV Protection: The blackened, carbon-rich surface of charred wood absorbs significant UV radiation. This absorption prevents UV rays from penetrating deeper into the wood, which would otherwise cause photodegradation., causing the wood to become brittle and lose its structural integrity.
Fire Resistance: Shou Sugi Ban wood’s charred layer is inherently fire-resistant. This carbon layer acts as an insulator, slowing down the burning process and protecting the inner layers of the wood. This fire resistance enhances safety and means that the wood can last longer in environments where fire hazards are a concern.
Environmental Benefits of Shou Sugi Ban
Natural Preservation Method The charring process naturally preserves the wood without chemical treatments. By avoiding chemical preservatives, Shou Sugi Ban helps reduce the release of potentially harmful substances into the environment and minimizes human health risks.
Longevity and Sustainability Charred wood can last significantly longer than untreated wood, reducing the need for frequent replacements. This extended lifespan means fewer trees must be harvested, contributing to sustainable forest management and conservation efforts.
Reduced Maintenance compared to traditional wood treatments, Shou Sugi Ban wood requires minimal maintenance. The charring process significantly enhances the wood’s resistance to weathering, meaning it doesn’t need to be re-finished as often. This reduction in maintenance helps lower the overall environmental footprint, as fewer resources are used for upkeep.
Carbon Sequestration While the initial charring process involves burning, which releases some carbon dioxide, the overall lifecycle of Shou Sugi Ban wood can have a positive environmental impact. Trees absorb carbon dioxide from the atmosphere as they grow, and this carbon remains stored in the wood even after it is cut and used. By extending the life of wood products through charring, Shou Sugi Ban helps keep carbon sequestered for a longer period, which is beneficial in mitigating climate change.
Use of Natural Finishes In addition to the charring process, the finishes applied to Shou Sugi Ban wood are often natural oils and waxes, which are less harmful to the environment than synthetic chemicals. These natural finishes can enhance the wood’s appearance and durability without adding toxic elements to its surroundings.
Crafting State-of-the-Art Shou Sugi Ban Designs for Lasting Performance Shou Sugi Ban is more than just a wood treatment; it is a testament to natural materials’ enduring beauty and resilience. At reSAWN TIMBER co., we are proud to bring this ancient Japanese technique to modern design by offering high-performance products that are as functional as they are beautiful.

Natural wood possesses inherent beauty and is frequently incorporated into construction designs for its aesthetic appeal. However, wood is a natural material susceptible to degradation due to climatic elements, moisture, and UV rays. To preserve natural wood’s integrity and longevity, the application of a protective topcoat is a standard practice for all timber building materials.
In the realm of wood protection, SiOO:X stands out as a revolutionary solution that provides timber with a long-lasting shield against the outside elements and delivers a captivating aesthetic transformation over time. Unlike conventional wood treatments that create a protective seal on the surface, SiOO:X penetrates deep into the wood fibers, forming a shield that enhances the durability and longevity from within.
SiOO:X leverages the natural environment and wood’s characteristics to gradually cure wood over one to three years. This unique curing process results in a protection system that imitates wood’s natural protective layer. The curing process also triggers a gradual color transformation within a short timeframe, mimicking the authentic weathering effect seen in natural wood.
Twin Gables Feat. SiOO:X Abodo Vulcan Cladding
Curing with Nature SiOO:X is crafted to work with nature. The curing process is intricately tied to the specific climatic environment where the wood cladding resides. The rate of change is often attributed environmental factors. Sunlight, rain, wind, and humidity are all factors that could affect the curing process*. Surfaces shielded from direct sunlight and harsh weather conditions, such as soffits or non-exposed walls, may undergo a slower rate of curing and color evolution. In contrast, the cladding that is fully exposed experiences more significant fluctuations.
Understanding the Curing Process SiOO:X Wood Protector holds a unique silicon and potassium formulation that reacts with moisture and carbon dioxide. This chemical reaction forms a protective barrier within the timber. SiOO:X’s chemical reaction can occur independently of sunlight, ensuring consistent and reliable performance regardless of weather conditions over time. It creates a long-lasting shield against moisture, and UV rays.
The Evolution of Color As the curing process progresses, the timber undergoes a remarkable transformation of color. The wood starts out in its natural coloration before gradually transitioning to a light whitewash tone, typically within six – twelve months of application. This initial phase represents the activation of SiOO:X’s protective properties that penetrate deep into the wood fibers. The timber gradually darkens to mid-gray ‘weathered’ tones, acquiring a timeless patina that adds depth and character to the wood surface. Exposed surfaces may undergo a more rapid color evolution than non-exposed walls. However, despite the differences in the rate of color evolution, the aesthetic outcome will be consistent across all surfaces over time.
Advantages Over Traditional Coatings SiOO:X’s natural curing process offers several advantages over traditional coatings, particularly when it comes to durability, aesthetics, and environmental sustainability. Conventional wood protector coatings’ efficiency diminishes over time with exposure to the sun, leading to fade in color and less protection against wear and tear. On the contrary, SiOO:X works with the environment and delivers a natural color evolution. Wood treated with SiOO:X offers long-lasting protection and reduces the need for frequent reapplications, which conserves resources and reduces maintenance costs.
An Eco-Conscious Formula With a clear focus on sustainability and eco-friendliness, SiOO:X is engineered with no VOC (volatile organic compound) formulation. It minimizes environmental impact while ensuring safety for users and our planet. By enhancing the longevity of wood, the lifespan of wooden structures is extended, contributing to waste reduction in the long run. Unlike other wood treatments that may leach harmful chemicals into the soil or waterways, SiOO:X is biodegradable and poses no risk to ecosystems.

Whether used in commercial or residential projects, reSAWN’s SiOO:X products offer unmatched longevity, sustainability, and aesthetic appeal, setting a new standard in modern wood protection.
*In case of problems with black spores the SiOO:X system creates a barrier that prevents algae and spores from penetrating the wood. Because SiOO:X does not contain any strong toxins it cannot prevent black spores from settling on the surface. Periods of rain or damp weather are especially favorable for these airborne spores, which can often be found on wood surfaces that are in the shade or exposed to the weather. Black spores need nutrients to grow and they get these from natural sugars in the wood. These substances are leached out of the wood in the first 1–4 years. The presence of black spores also decreases as the SiOO:X silicon shield matures and gets stronger. For a full Care & Maintenance Guide, click here.

The material can be used to seamlessly blend with a variety of design styles, from traditional to modern, making it a multifaceted choice for architects and designers seeking a timeless and visually appealing solution.
Thermally Modified Process The thermal modification process involves exposing the Red Oak to high temperatures in a controlled environment, altering its chemical composition. This process enhances the wood’s durability, stability, and resistance to decay. As a result, thermally modified Red Oak cladding offers a longer lifespan and requires less maintenance when compared to unfinished wood.
Resistance to Decay One of the primary concerns with wood cladding is its susceptibility to rot and decay. Thermally modified Red Oak addresses these concerns by becoming highly resistant to decay through the thermal modification process. The high temperatures cause chemical changes in the wood, leading to the modification of its cellular structure. Hemicellulose, one of the wood’s components, is permanently affected. The breakdown of hemicellulose reduces the wood’s ability to absorb and retain water, making it less susceptible to decay. This resistance ensures that the cladding remains durable and maintains its original quality, even in challenging outdoor environments.
Stability and Dimensional Consistency The thermal modification process not only enhances the wood’s visual appeal but also improves its stability. The timber experiences chemical modification during the process that significantly reduces the timber’s susceptibility to absorb moisture and swell, resulting in a more dimensionally stable material. This stability is crucial in ensuring that the cladding maintains its structural integrity over time, even in varying environmental conditions.

For centuries wood has been a popular and traditional material for various applications and its timeless appeal continues to endure in modern times. Its versatility, sustainability, and aesthetic qualities make it a preferred choice for a wide range of building uses, from commercial to residential applications.
As the popularity of wood continues to grow in the construction and design industry, manufacturers are actively developing new technologies to expand the product offerings. This effort caters to the increasing demand and aims to elevate the performance and sustainability of wood in construction and design applications. Among these methods, thermal modification stands out as a process that transforms wood into a material with improved durability, stability, and aesthetic qualities. This article delves into the various aspects of thermally modified wood, exploring the process and the remarkable benefits it brings.
Thermal modification is an eco-friendly process that involves altering wood using heat energy, omitting the use of additional chemicals. The heart of the process lies in the thermal modification itself. Wood undergoes controlled heating in an oxygen-deprived environment, while gradually raising the heat to the desired temperature. Precise control is exercised to ensure uniform heating throughout the material. This process induces structural changes within the wood, enhancing its properties without risking combustion.
The wood is maintained at an elevated temperature for a specified duration, allowing the thermal modification to permeate its cellular structure. This cooking phase is pivotal for achieving the desired physical and chemical transformations. The controlled application of elevated temperatures in the absence of oxygen leads to several changes in the cellular components of wood, including hemicellulose, cellulose, and lignin—which are three major components that contribute to the overall mechanical properties of wood.
Hemicellulose Decomposition Hemicellulose, a polymer comprised of sugars found in timber, constitutes a significant portion of wood, accounting for 20-35% of its dry weight. It plays a crucial role in moisture absorption and facilitates cross-linking among cellular components. During thermal modification, hemicellulose undergoes decomposition, leading to a decrease in its content. This process releases water vapor and other volatile compounds from the timber. The reduced hemicellulose content decreases the timber’s capacity to absorb and release moisture, thereby improving its overall stability.
Cellulose Crystallinity Cellulose, a fibrous structure serving as the primary constituent of wood fiber, plays a pivotal role in enhancing the strength and rigidity of wood. The crystalline regions of cellulose are well-organized and tightly packed. The degree of cellulose crystallinity in wood influences the wood’s physical properties, such as strength and stiffness. The heat treatment causes the cellulose chains to become more ordered and crystalline, increasing its stiffness. This alteration contributes to improved dimensional stability and reduced susceptibility to swelling and shrinking when exposed to changes in moisture levels.
Lignin Modification Lignin is a complex polymer that holds cellulose fibers together. It acts as a binding substance and provides structural support and rigidity to wood. At higher temperatures during thermal modification, lignin depolymerizes and breaks down into smaller fragments. The heat energy then redistributes and recondenses these broken lignin fragments. The reorganization of these fragments can contribute to an increase in lignin content, resulting in altered characteristics such as improved dimensional stability.
Lignin is the primary contributor to the natural brown color of wood. Various wood processing methods can modify or eliminate lignin content, thereby influencing the wood’s color. Thermal modification tends to contribute to the enhanced coloration of the wood, often resulting in a darker and more uniform appearance.
Cooling Phase Following the thermal modification, a carefully managed cooling phase follows to prevent abrupt temperature changes that could compromise the integrity of the modified wood. By managing the cooling phase correctly, the risk of structural damage to the wood is minimized. Slow cooling helps prevent surface irregularities, such as warping or cupping, which might occur if the wood experiences sudden temperature fluctuations.
In summary, thermal modification process changes the cellular characteristics and interaction among hemicellulose, cellulose, and lignin. These alterations enhance the mechanical properties of the wood, resulting in improved dimensional stability, reduced susceptibility to moisture absorption, and increased resistance to decay.
Thermally Modified Wood Cladding Thermally modified wood has gained significant attention in recent years as an excellent option for wood cladding. The result is a material with enhanced durability, stability, and resistance to decay, making it particularly well-suited for exterior applications.
SylvaTM and Abodo® are two examples of wood species that undergo thermal modification to enhance their performance as cladding materials.
Sylva is created from North American Red Oak, known for its attractive grain patterns and warm, reddish-brown hues. When thermally modified, it not only retains these aesthetic qualities but also gains increased resistance to decay, insects, and other environmental factors. This makes it an excellent choice for exterior cladding, where it can provide both visual appeal and long-term durability.
Abodo Vulcan thermally modified wood cladding is created from New Zealand plantation timber. The thermal modification process gives Vulcan cladding superior stability and reduced resin content.

Humans have always connected deeply with nature because we evolved in natural environments. For thousands of years, we have lived in close proximity to nature, relying on it for survival. Our brains and bodies evolved to function in these natural environments, and as a result, we have an innate connection to nature that has persisted throughout human history. Even as we have become more urbanized and modernized, our connection with nature has remained strong because it is ingrained in our biology and psychology.
According to several authoritative studies (Workplaces: Wellness+Wood=Productivity), (Wood: Nature Inspired Design), and (Why Do We Feel Better With Wood?) exposure to natural products like wood creates similar health benefits to those created by spending time in nature. Incorporating natural materials such as real wood cladding and flooring into a built environment helps reduce blood pressure, heart rates, and stress levels while improving well-being, creativity, cognitive abilities, and the air we breathe. The concept of biophilia was introduced in the 1980s to highlight the importance of our connection to nature and the potential benefits that can be gained from it.
Synthetic building materials often recreate the look of wood because wood is a popular and traditional building material that has been used for centuries. Wood’s warm, natural look and feel is difficult to achieve with non-natural materials. By mimicking wood, manufacturers can create low-cost building materials with a similar appearance and texture to wood, but lacking the warmth, intrinsic qualities, and health benefits afforded by real wood materials.
The influence that wood has on the building materials market can be seen everywhere. reSAWN recently attended the 2023 International Builders’ Show (IBS), which is an annual trade show for the residential construction industry, hosted by the National Association of Home Builders (NAHB). The show featured exhibits and educational sessions focused on new products, innovative technologies, and industry trends related to home building and remodeling. The use of wood, wood influence, and the creation of wood-like aesthetics was prevalent throughout the show. Even companies that were not offering a wood product, utilized wood-like textures in their booths to highlight their product or service.
Vinyl Siding Made to Look Like Wood
Vinyl siding is a popular choice in the US for a wood-like look without the perceived maintenance. Vinyl can be made to look like different types of wood, including cedar, oak, and pine. It is also affordable and durable, making it a common choice for many projects. However, there are some potential downsides to using vinyl siding that need to be considered.
Vinyl siding is made of polyvinyl chloride (PVC), a plastic material that is derived from petroleum – which is a non-renewable resource. The production of PVC and its disposal can result in toxic pollutants being released into the environment, including dioxins, which are known to be harmful to human health and the environment.
Energy-intensive manufacturing: The production of vinyl siding requires a significant amount of energy, mainly from non-renewable sources such as coal and natural gas, which contributes to greenhouse gas emissions and climate change.
Limited recyclability: Vinyl siding is difficult to recycle, and it may end up in landfills where it can take hundreds of years to break down. This contributes to environmental pollution and wastes resources.
Installation and maintenance: The installation of vinyl siding requires the use of various chemicals and solvents, which can have negative environmental impacts. In addition, vinyl siding can crack or fade over time, requiring replacement, which leads to more waste.
Fiber Cement Made to Look Like Wood
Another material that mimics the look of wood is fiber cement. It’s a widely used building material that’s made from a mixture of cement, sand, and cellulose fibers. While it has many benefits, such as durability, fire resistance, and low maintenance, there are also significant environmental issues associated with its production and use.
Carbon emissions: The production of fiber cement involves high energy consumption and emits significant amounts of carbon dioxide, contributing to global warming.
Water use: The production of fiber cement requires a significant amount of water, which can put pressure on local water resources in areas where water is scarce.
Waste disposal: The production process generates a significant amount of waste, including cement dust, which can cause air pollution if not properly disposed of.
Toxicity: The production of fiber cement can result in the release of toxic chemicals, such as asbestos, silica, and formaldehyde, which can pose health risks to workers and nearby communities.
Transportation: Fiber cement is a heavy and bulky material that requires a lot of energy to transport, contributing to greenhouse gas emissions.
Composite Decking Made to Look Like Wood
Composite decking is a popular alternative to traditional wood decking because it is durable, and requires little maintenance. However, there are some environmental issues associated with composite decking that should be considered.
Manufacturing: The production process of composite decking involves the use of a variety of chemicals, including resins, wood fibers, and plastics. These chemicals can release harmful emissions into the air and water during production.
Disposal: Composite decking materials are not biodegradable and can take up valuable space in landfills if not properly recycled. Some composite decking materials contain hazardous chemicals, making them difficult to recycle or dispose of safely.
Non-renewable resources: Most composite decking is made from a combination of wood fibers and plastic, both of which are non-renewable resources. This means that the production of composite decking contributes to the depletion of these resources.
Maintenance: Although composite decking requires less maintenance than traditional wood decking, it still requires periodic cleaning with chemicals that can harm the environment. However, with the onset of modified woods like Accoya, there are now many maintenance-free options on the market.
Porcelain Tile Made to Look Like Wood
One of the newest materials to mimic wood is porcelain tile. Porcelain tile can be made to look like different types of wood, including oak, maple, and walnut. It is also very durable and water-resistant, making it a great choice for areas that experience moisture or high traffic.
Porcelain tile is generally considered an environmentally friendly flooring option, as it is made from natural materials such as clay and minerals, and can be recycled at the end of its life. However, there are some environmental issues associated with porcelain tiles that should be considered:
Energy consumption during production: The production of porcelain tile requires a significant amount of energy, which contributes to greenhouse gas emissions and climate change.
Water usage during production: The production of porcelain tile requires large amounts of water, which can contribute to water scarcity and pollution.
Transportation emissions: Porcelain tile is often imported from overseas, which results in transportation emissions and contributes to climate change.
Waste generation: The installation of porcelain tiles can generate waste, including cut-off pieces and broken tiles, which can contribute to landfill waste.
Chemicals used in production: The production of porcelain tile may involve the use of chemicals such as glazes and sealants, which can be harmful to the environment if not properly managed.
When a single design is repeated over a large area, it can create a visual monotony that may appear repetitive.
Laminate Flooring Made to Look Like Wood
Laminate flooring that looks like wood is a popular choice for many homeowners and builders because it provides the appearance of hardwood flooring at a more affordable price. Laminate flooring is made from composite wood materials and is designed to mimic the look of hardwood planks, including the texture and grain patterns.
While laminate flooring has many advantages, there are some drawbacks to consider before choosing it for your home or building project.
Not as durable as hardwood: Although laminate flooring is more durable than some other types of flooring, it is not as durable as hardwood. Heavy furniture, high heels, and pet claws can all cause scratches and dents in laminate flooring.
Susceptible to water damage: Laminate flooring is made from a wood-based core, and as such, it can be damaged by excessive moisture or water exposure. Spills or leaks that are not cleaned up quickly can cause the planks to warp or buckle.
Can look artificial: While laminate flooring is designed to look like real wood, it is still an artificial product, and some people may find that it looks less authentic than hardwood flooring.
Difficult to repair: If a section of laminate flooring becomes damaged, it can be challenging to repair without replacing the entire plank or section of the floor. This can be costly and time-consuming.
Formaldehyde emissions: Formaldehyde is a chemical used in the adhesives and resins used to make laminate flooring, and it can be emitted into the air over time. Formaldehyde is a known carcinogen and can cause health problems, especially for those with respiratory issues. However, many laminate flooring manufacturers now use low-formaldehyde adhesives and resins to reduce the risk of emissions.
Sustainability of materials: The majority of laminate flooring is made from a core of high-density fiberboard (HDF) made from wood fibers, which can be derived from unsustainable sources such as old-growth forests. While some manufacturers use recycled or sustainably sourced wood fibers, others may not be as environmentally responsible.
Disposal: Laminate flooring cannot be easily recycled and may end up in landfills. When disposed of, it can release formaldehyde and other harmful chemicals into the environment. However, some companies have started recycling programs to reduce waste and environmental impact.
Short lifespan: Laminate flooring is generally not as durable or long-lasting as other flooring materials, such as hardwood. This means that it may need to be replaced more frequently, leading to more waste and environmental impact.
While laminate flooring is a popular and affordable option, it may not be the best choice for all situations. To mitigate the environmental issues associated with laminate flooring, consumers can look for products made from recycled or sustainably sourced materials, choose low-formaldehyde options, and properly dispose of old flooring. It is also important to select flooring that is durable and has a long lifespan to minimize waste and environmental impact.
Aluminum Made to Look Like Wood
There are some manufacturers that offer aluminum facade solutions for homeowners and commercial properties looking to achieve the look of wood. The aluminum products mimic the appearance of natural wood grains, knots, and textures.
While aluminum facades offer numerous advantages such as durability, flexibility, and low maintenance, there are also some disadvantages that should be considered, including:
Cost: Aluminum facades can be expensive compared to traditional wood cladding materials.
Corrosion: Aluminum is susceptible to corrosion if it is not properly treated or coated. Exposure to moisture and chemicals can lead to rust and discoloration, which can detract from the appearance of the building.
Thermal conductivity: Aluminum is a good conductor of heat, which can lead to energy loss in buildings. Additional insulation may be required to offset this problem.
Environmental concerns: The production of aluminum requires a significant amount of energy and generates greenhouse gas emissions. Additionally, the extraction and processing of aluminum can have negative impacts on the environment.
Limited design options: While aluminum is a flexible material, there may be limitations to the design options available with this cladding material. Some architects and designers may prefer other materials for their aesthetic appeal or greater design flexibility.
Scratches and dents: Like all aluminum cladding materials, Knotwood is susceptible to scratches and dents, which can detract from its appearance.
Technological Updates in Wood
There have been many recent technological updates in the use of wood as a building material, which have made it more versatile, efficient, durable, and dimensionally stable.
Modified Wood Options
Various environmentally friendly chemical and heat treatments can be used to modify the properties of wood. For example, acetylation can make wood more durable and resistant to decay, while thermal modification can improve its stability and strength. This type of wood requires minimal upkeep to preserve its appearance and structural integrity over time. Low-maintenance modified wood products can be a great option for homeowners who want the beauty and warmth of wood without the hassle of regular maintenance. However, it’s important to choose the right type of wood for your specific application and to follow any recommended maintenance guidelines to ensure that your wood products last as long as possible.
Structural Analysis Software
Structural analysis software can simulate the performance of wood structures under different loads and conditions, allowing engineers and architects to optimize designs for strength, durability, and efficiency. This technology has led to the development of new building systems and techniques that use wood in innovative ways.
Sustainable Forestry Practices
Technology has made it possible to manage forests more sustainably, by using satellite imagery, remote sensing, and other tools to monitor forest health, track tree growth, and identify areas of concern. This technology has helped to reduce the environmental impact of harvesting wood while ensuring a steady supply of sustainably harvested timber for building and other uses.
Overall, technology has helped to make wood a more versatile, efficient, durable, and dimensionally stable building material, opening up new possibilities for architects, engineers, and builders to create innovative and sustainable structures. Moreover, wood has a natural warmth and character that is difficult to replicate with synthetic materials. While there are synthetic materials that can mimic the appearance of wood, they often fall short in terms of sustainability, texture, color variation, and overall aesthetic appeal.
Wood is one of the most mimicked building materials because of its adaptability, availability, and natural beauty. It can be shaped, cut, carved, and finished in a variety of ways, allowing it to be used for a wide range of applications, from furniture and flooring to building construction. In summary, while alternatives to natural wood products may have some advantages, they may not be able to fully replace the environmental and authenticity benefits that come with using natural wood. Plus due to technological updates in the use of wood as a building material, it is more versatile, efficient, durable, and sustainable than ever before.

Thermal modification is a process that utilizes high heat to alter the dimensional composition of wood. The cellular structure is changed by applying heat without oxygen, which creates a controlled chemical reaction. The thermal modification process permanently modifies the cell walls of the wood and results in improved durability of the wood as well as increased dimensional stability.
Three Falls Residence – GRAPHITE Abodo Vulcan Cladding
The aim of modified wood is to overcome the shortcomings of standard timber. The modification process enhances the performance of the wood, resulting in improvements in the longevity of timbers – dimensional stability, decay resistance, reduced water absorption, less expansion/contraction, etc. In addition, since most advanced modification processes are environmentally friendly, the materials can still be disposed of properly at the end of the product life cycle.

What Are The Benefits of Using Thermally Modified Wood?
Durability: Wood becomes instantly more durable after being thermally modified. Water absorption in regular wood can cause warping, discoloration, and even the growth of bacteria or fungi. This is not an issue with thermally modified wood. Water cannot warp or deform it because the modification process naturally changes the cellular structure of the wood.
Aesthetics: Thermally modified wood has a beautiful, consistent chocolate-brown color from surface to core.
Sustainability: Solid wood building materials have a net-negative CO2 profile – better than any conventional building material. It requires less energy to create the finished product than other building materials such as concrete, metal, or plastic.
Environmentally Friendly: Many exterior wood products are treated with wood preservatives – some more toxic than others. The thermal modification process uses heat and steam to cure the wood. There are no harmful toxins or chemicals that are used in the process.

Phase 1 – The kiln is slowly elevated in temperature until the moisture content of the wood is essentially zero %. The wood in the kiln is then heated further until it reaches the desired modification temperature – in most cases 230 degrees Celsius for outdoor end-use applications.
Phase 2 – The kiln is held at the modification temperature for a prescribed time to achieve full modification. This time is the critical point in the process.
Phase 3 – The kiln is allowed to cool, and the wood is reconditioned with steam (we bring the moisture content back to around 7%). Once cool enough the wood can be extracted from the kiln.
reSAWN TIMBER co. is proud to be the exclusive manufacturer and distributor of Abodo® thermally modified Vulcan cladding and decking products in the USA.
Kebony Modified Wood
Kebony is considered a dually-modified wood, which means it’s both chemically and thermally modified. That happens through their proprietary process called furfurylation. The Kebony technology modifies wood by forming stable, locked-in furan polymers in the wood cell walls. These increase the dimensional stability, as well as durability and hardness, of the wood. This process is based on impregnation with furfuryl alcohol produced from agricultural crop waste. Kebony thus uses a plant-derived waste product to give enhanced strength and durability to another plant product – namely wood.
Kebony Clear Decking
Kebony wood is safe since the wood does not splinter and doesn’t contain toxins or chemicals, nor does the wood get too hot in the summer. Furthermore, Kebony wood is resistant to rot and fungi, and other wood-destroying microorganisms in an above-ground context. Kebony is a low-maintenance material that does not require additional treatment beyond normal cleaning, thus, no oils or other impregnation solutions are needed.
Thermally Modified Red Oak
Thermally modified red oak is a popular option for locally sourced timber from the United States. In North America, red oak trees are prevalent and grow to a height of around 70 feet and a trunk diameter of 36″. Being the largest species group, it is highly sustainable.
While there are copious amounts of international building material manufacturers, local suppliers can offer benefits that overseas vendors cannot.
Carbon Footprint Reduction – Our relationship with our environment truly matters. Building materials that are locally sourced means shorter trips to haul, less greenhouse gas emissions, and less diesel fuel consumption.
Support Products Made in the USA – By specifying local materials, a product’s sustainability profile extends to extraction, manufacturing, and transportation practices.

In this video & article, we discuss reSAWN’s Accoya modified wood offering which is prefinished with a waterborne exterior oil. Our one-coat (1C) and two-coat (2C) product offerings provide specifiers with the choice of a more saturated color if desired.
1C Option – Finished with 1 Coat
‘1C’ denotes Accoya wood that is prefinished with one coat of our proprietary exterior oil in the factory. There is no need to apply a second coat of finish post-install.
2C Option – Finished with 2 Coats
‘2C’ denotes Accoya wood that is prefinished with one coat of our proprietary exterior oil in the factory AND will require the installer to apply a second coat of finish post-install. This finish will be included on the sales order and shipped with the materials. Applying a second coat of finish post-install will further saturate the initial color of the cladding and extend the duration of the deeper color.
The video focuses on RAILAY 1C and RAILAY 2C, two of reSAWN’s Accoya wood products with a waterborne exterior oil.
Video Transcript:
Hi, I’m Diane with reSAWN TIMBER, and I’m here today to talk to you about several of our Accoya products that are available with 1C or 2C exterior finish. 1C indicates Accoya is prefinished with one of our exterior oils in the factory, and this does not require a second coat. 2C indicates Accoya is prefinished with one of our exterior oils in the factory, which will require a second coat onsite by the installer.
The big difference between 1C and 2C is the color saturation on day one and as it weathers over time. Applying a second coat of Accoya does enhance the initial color of the exterior cladding and it extends the life of that deeper color over time. However, if you choose not to apply that second coat of finish, that can be a cost savings for your project.
I’m here at the factory in Pennsylvania and we do testing of our own products outside on our weathering rigs. We test for aesthetics and performance. So here are two examples. This is RAILAY 1C and RAILAY 2C – these have been outside on our weathering rigs since September 2021. That is 10 months of accelerated weathering. It’s considered accelerated weathering because it’s on our rigs on a 45 degree angle facing due South.
reSAWN TIMBER co. Accelerated Weathering Rigs
So 10 months of accelerated weathering represents approximately 30 months on the job site. So you can see they are weathering a little bit differently, but yet they’re weathering beautifully. So as you have your project needs or requirements for exterior cladding and Accoya modified products, give us a call at reSAWN TIMBER and we’d be happy to help you out. Thanks!

How is Accoya wood modified?
Accoya wood is modified through a process known as acetylation. Accoya takes radiata pine, a softwood, and subjects it to a vinegar known as acetic anhydride. Acetyls are naturally present in wood, and acetic anhydride enhances the hydroxyl groups, providing water-repelling characteristics. This process turns the softwood into a hardwood by preventing the cells in the wood from being able to absorb water. This vinegar is verified as non-toxic with Cradle to Cradle Certified Gold, scoring ‘Platinum’ for Material Health. This modification process gives Accoya its durability and rot and decay resistance.
Accoya wood accetylation process
Does Accoya wood require a lot of maintenance?
Not only is Accoya’s durability proven, but it has also been shown to retain its appearance, requiring much less frequent maintenance than other wood species. Since Accoya wood undergoes the acetylation modification process, it requires little to no maintenance. The modification process enhances the performance of Accoya wood, providing outstanding dimensional stability that results in lower maintenance frequency and therefore less coating over the lifetime of the product.
Accoya wood doesn’t require recoat maintenance. However, if the desire is to get back to that day one color, we do recommend a recoat for aesthetic purposes. Maintenance and recoating guidelines vary by product. Contact reSAWN TIMBER co. for product-specific information.
