In the world of architectural design and construction, the choice of building materials plays a pivotal role, influencing the aesthetic appeal and a structure’s sustainable commitment and functional aspects. With the growing emphasis on sustainability and reducing carbon emissions, staying well-informed and possessing the knowledge to design and build with sustainable materials has become more crucial by the day.
According to The Institution of Structural Engineers, the building and construction industry is responsible for 40% of annual carbon dioxide emissions. Choosing appropriate building materials represents the first step in decarbonizing the building and construction sectors. The global popularity of using renewable, biogenic building materials is rising due to high sustainability awareness. A building product’s embodied carbon accounts for all the carbon emissions released throughout the product’s entire supply chain and life cycle. When opting for a building material, consideration should be given to all factors influencing carbon emissions throughout its entire life span.
Beginning as raw material, wood functions as a carbon sink, actively storing carbon dioxide from the environment. Contrary to the prevailing belief that harvesting trees disrupts the ecosystem and diminishes the photosynthesis process, wood remains a carbon sink even after being harvested. The regrowth of trees following harvest plays a crucial role in sustaining and balancing the ecosystem. Throughout the regrowth process, trees absorb carbon from the atmosphere. In addition, when forestry is managed sustainably with a focus on biodiversity, the diversity of the ecosystem provides an environment for microorganisms to thrive. These microorganisms actively contribute to soil restoration and enhance the productivity of emerging forests. Consequently, the soil gains capacity as a carbon store, effectively mitigating carbon dioxide emissions into the atmosphere.
A significant factor influencing the embodied carbon of a building product is transportation. Arup’s Embodied Carbon report highlights that the logistics involved in transporting raw materials to the factory contribute to 8-10% of the embodied carbon while transporting the finished product to the construction site accounts for 50-55%. The sourcing of materials holds paramount importance in determining the embodied carbon of building materials, impacting manufacturers and the decisions of architects and builders.

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. It’s naturally durable so the timber doesn’t require any chemical preservatives, and has a beautiful, consistent brown tone.
The versatility of thermally modified wood and its eco-friendly attributes establish it as a compelling choice for building materials across various applications, spanning from interior to exterior and encompassing both residential and commercial settings.

Wildfires have become a common topic and focus worldwide as they are becoming more frequent, intense, and challenging to contain. The rapid spread of wildfire into inhabited areas could cause devastating losses of life and health, as well as financial and property damages.
The Wildland Urban Interface (WUI) is a critical area where human development meets the natural, undeveloped landscape. The population is rapidly growing in the U.S., and more and more people and families are choosing to live in the outskirts, suburbs, and rural expanses. Housing development follows the population and grows into wildlands. As communities expand, the interface between wildlands and urban areas becomes increasingly prominent—a high-risk area when wildfires occur.
The Wildland Urban Interface is not static as it is constantly growing. The WUI zone varies across regions depending on climate, topography, vegetation, and land use. WUIs typically include suburban neighborhoods, recreational areas such as golf courses, and communities near natural landscapes. These locations are where wildfires have the most significant impacts on human lives. The latest information on WUI areas can be found on the official website of the local fire department.
Vegetation, topography, and human activities are three major factors of wildfire spread in the WUI areas. The lush greenery enhances the aesthetic appeal of residence placements. Its combination with natural topography, such as steep slopes, canyons, and ravines, provides mental solace for residents. However, when wildfires occur, the vegetation becomes fuel for wildfires, and the layout of the land can affect how quickly flames advance, adding complexity to managing and mitigating fire risks.
In addition to natural wildfires, human activities could pose fire risks in these interface zones. Recreational outdoor activities, agriculture, and urban development increase the likelihood of human-induced wildfires. Human activities elevate the probability of initiating fires and add challenges to emergency response and evacuation. Rapid urbanization and sprawling developments create numerous access points for fires, making it challenging for firefighting crews to swiftly contain blazes. Evacuating residents during a wildfire becomes a logistical puzzle, requiring meticulous planning and coordination among emergency services.
Mitigating and preparing for wildfires, particularly in wildland-urban interfaces, are critical concerns for the public and federal, state, and local governments. These efforts are essential to safeguard communities from potential losses and damages. Common fire mitigation strategies involve community planning, comprehensive fire and life safety regulations, and stringent building standards. Educating and preparing the local communities about the devastating effects of wildfires can help reduce human-ignited fires and improve emergency responses. Creating ample defensible space between structures by reducing vegetation helps decrease the speed of fire spread. Additionally, choosing WUI-compliant building materials during new and remodel construction can mitigate the impact of wildfires and minimize the risk of ignition.
Living on the edge of wildlands comes with the allure of natural beauty and the challenges of managing the inherent risks. The Wildland Urban Interface demands a proactive and collaborative approach to safeguard communities against the threat of wildfires. Through careful planning, education, and investment in firefighting resources, residents and policymakers can work together to create resilient communities that coexist with nature while minimizing the impact of potential disasters. As we continue to expand our urban footprint, understanding and addressing the complexities of the Wildland Urban Interface will be crucial for building a safer and more sustainable future.
In an unprecedented reversal of American history, the demographic landscape of the United States is undergoing a transformative shift. A growing number of Americans are choosing to relocate from major cities and metropolitan hubs to the outskirts, suburbs, and rural expanses, propelled by a multitude of factors. As individuals settle in and around diverse ecosystems such as forests, grasslands, and shrub lands—also known as wildland-urban interface (WUI) zone—ramifications of this population shift become more pronounced.
This migration trend unfolds against an increasingly pressing concern—climate change-induced wildfires across North America. The intricate interplay between human habitation and natural landscapes amplifies the challenges associated with wildfires. With rising temperatures and prolonged droughts heightening the risk of wildfires, a significant emphasis is placed on enhancing safety measures and protections in the WUI zone.
Introduction of Wildland Urban Interface Construction Codes
Over the years, with the escalating threat of wildfires, there has been a growing development of building codes tailored specifically for areas prone to wildfires.
The Wildland-Urban Interface (WUI) provisions are typically integrated into state or local building codes. California is known for introducing its own set of WUI zone construction requirements within the California Building Code (CBC) in 2008. CBC regulations mandate that building products intended for use in the WUI zone or State Responsibility Area (SRA) must adhere to specific directives. The WUI construction code primarily aims to enforce heightened standards for fire resistance and ignition resistance in the built environment.
A home or building designed and constructed with meticulous attention to detail and the use of compliant building materials significantly enhances its chances of withstanding a wildfire. There are two common ways to identify optimal building products for properties located in wildfire-prone areas: opting for WUI-Compliant building products or selecting products listed under CAL FIRE Building Materials Listing Program.
WUI-Compliant Building Products
WUI-compliant products generally refer to products and materials that meet specific standards and regulations outlined for the Wildland-Urban Interface zones.
According to California Building Code (CBC), the minimum requirement for building envelope components, such as siding/cladding is that an exterior wall covering or wall assembly, shall comply with one of the following requirements:
Wall assemblies that have been tested in accordance with the test procedures for a 10-minute direct flame contact exposure test set forth in ASTM E2707 with the conditions of acceptance shown in Section 707A.3.1
Wall assemblies that meet the performance criteria in accordance with the test procedures for a 10-minute direct flame contact exposure test set forth in SFM Standard 12-7A-1.
CAL FIRE Building Materials Listing Program
CAL FIRE is a California state agency responsible for safeguarding natural resources within areas designated by the State Board of Forestry as State Responsibility Areas (SRA). In alignment with this mission, the Office of State Fire Marshal (OSFM) introduced the Building Materials Listing (BML) Program. This program serves as a comprehensive initiative aimed at evaluating and certifying a diverse array of building materials. Product manufacturers are required to pass rigorous testing conducted through laboratories accredited by the State Fire Marshal (SFM), ensuring their building materials meet stringent standards for the WUI zone.
The BML Program provide authorities, architects, engineers, contractors, and the fire services with a reliable and readily available source of information when they do not have a staff or subject matter expert to assess the building material quality.
There is a common belief that wood, being perceived as combustible and flammable, is not considered a safe material in proximity to fire. As a result, wood is often not the first come to mind when selecting building materials for building structures in wildfire-prone areas. As technology advances, reSAWN TIMBER co. addresses this challenge by innovatively modifying wood structures. The thermally modified wood offerings, Abodo and Sylva, can be more resistant to fire than untreated wood. The thermal treatment alters the chemical composition of the wood, leading to a decrease in the content of flammable substances within the material, while preserving the original aesthetic of wood.
As demographic trends evolve and more individuals relocate to wildland-urban interface (WUI) zones, architects, builders, and homeowners must stay well-informed about the escalating wildfire risk. This necessitates diligent research, selecting building materials by code requirements, and preserving aesthetic appeal throughout the construction process.

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.
