Can Mass Timber and Wood Be Used in Data Centers?

By Erin Figueroa In Exterior Cladding, Wood University /   No Comments

As artificial intelligence, cloud computing, and digital storage grow, so does the demand for data centers. The expansion of digital infrastructure and building these facilities has a large environmental impact. Most data centers rely heavily on steel and concrete, materials with high embodied carbon. At the same time, developers and tech companies face increasing pressure to reduce carbon emissions. Mass timber and solid wood building materials offer a lower-carbon alternative.

What is Mass Timber? 

Mass timber refers to engineered wood products made by layering and bonding lumber into strong structural panels and beams. These high-performing materials are designed for commercial buildings and large-scale construction and meet modern building codes for safety and fire resistance.

While mass timber is common in offices, schools, and multifamily housing, it’s now being explored for more technical building types, including data centers. 

Can Wood Be Used in Data Centers?

While much of the conversation around mass timber focuses on structure, wood can also be integrated into data center design in more targeted ways. Not every project will pursue a full mass timber structure—but many can incorporate wood strategically without compromising performance or reliability.

One of the most practical applications is exterior wood cladding. As data centers expand, their physical footprint and visual impact on surrounding communities continue to grow. Wood cladding offers a natural material expression that helps large-scale buildings integrate more thoughtfully into their environment and architectural context. When properly specified, solid wood cladding can meet durability, fire performance, and weathering requirements of high-performance building envelopes.

Wood flooring and interior cladding can also be used in controlled interior environments such as offices, lobbies, and support spaces, offering biophilic design strategies that contribute to occupant wellbeing and environmental quality.

By approaching wood as part of a broader material strategy—not just a structural system—project teams can incorporate it in ways that align with performance expectations and budget.

Why Consider Mass Timber and Solid Wood Material for Data Centers?  

Mass timber data centers use engineered wood as part of the primary structural system, offering an alternative to traditional steel and concrete construction while meeting the same performance but lowering the building’s carbon footprint.

Data centers operate 24/7, so the materials used to build them matter. The carbon created during construction can make up a large portion of the building’s total emissions.

As companies track their environmental impact, material choices are becoming more important in construction. Using mass timber and solid wood cladding in data centers helps to achieve emissions targets and corporate net-zero goals.

Why Project Teams are Exploring Timber: 

  1. Reducing Embodied Carbon  

    Data centers have large structural footprints, and replacing portions of steel and concrete can significantly lower the upfront emissions. Microsoft announced a 35% reduction in the Embodied Carbon Footprint of its new data centers compared to steel construction.A building’s total emissions come from several stages, including material production, daily operation, and what happens at the end of the building’s life. Using timber can reduce emissions during these stages. Scientists state that this approach could reduce global CO2 emissions by 14-31%.  

  2. Lower Costs 

    Firms confirm that mass timber reduces costs by more than 5%. Since timber is a lighter structural system than alternative materials, it can reduce foundation requirements. This reduction leads to lower material and labor costs. 

  3. Speed of Construction  

    Prefabricated timber components can reduce build timelines and increase the speed of building construction by up to 25%. The lighter foundation also allows for shorter schedules, due to less excavation and concrete work, as well as quicker installation for structural framing. 

  4. Alignment with Environmental, Social, and Governance (ESG) Goals  

    Many tech companies have intensive sustainability commitments, including the need to align with ESG goals and qualify for LEED credits. Low-carbon materials support those goals. Sustainable mass timber is transparently sourced from responsibly managed forests that store carbon and preserve biodiversity and water quality. 

  5. Fire Safe 

    Mass timber can be safely integrated into data center environments when designed in accordance with established fire codes—just like steel or concrete systems. What differentiates mass timber is its predictable performance in a fire. Rather than weakening rapidly, which is a common belief, it forms a char layer that slows combustion and helps maintain structural integrity over a defined period. This allows engineers to design assemblies that meet required fire-resistance ratings with a high degree of confidence. 

    In mission-critical facilities where risk mitigation and uptime are paramount, fire performance is achieved through a layered, system-based approach. Code-compliant timber structures incorporate fire-rated wall assemblies, automatic sprinkler systems, and compartmentalization strategies consistent with other construction types. In addition, solid wood materials such as fire-retardant-treated wood (FRTW) for exterior applications, and Class A-rated topical finishes for interior surfaces, can be specified to reduce flame spread and meet code requirements. 

    When properly detailed and engineered, these strategies allow wood to be used within data center environments—supporting both performance and safety without compromising operational resilience. 

Benefits Beyond Sustainability 

  • Early adopters can demonstrate leadership in sustainable infrastructure.  
  • As companies begin to measure carbon more consistently, the materials used in buildings become more important to long-term value. 
  • The global cross-laminated timber market size is expected to reach USD 3.56 billion by 2030, leading to increased workforce growth. 
  • Employees report better morale, productivity, and sense of wellness in these spaces. 

As digital infrastructure expands and benefits become clearer, the industry is starting to rethink how projects are designed from the ground up, with a growing responsibility to build intentionally.  

Materials and Support Designed for the Life of the Structure 

Selecting responsibly sourced materials that align with the 100-year lifespan of mass timber structures is an important consideration. Exterior wood components must be able to perform over time alongside the structure itself. Modified wood species and high-performance finishes can help improve durability, reduce maintenance, and support long-term performance. 

For complex, fast-moving, and large-scale builds such as data centers, careful evaluation of wood species, modification methods, and finish systems ensure alignment with design intent and project requirements. Prefinished wall assembly systems streamline installation, support proper ventilation, and simplify coordination across teams. Specialized guidance is also a critical component for the integration of solid wood cladding within mass timber assemblies, ensuring structural compatibility and compliance with building codes.  Addressing these considerations early in the design and specification process supports predictable timelines and smoother coordination during construction. 

Looking Ahead: Designing with Intention   

Mass timber data centers represent an evolving approach to construction—one that balances structural performance with environmental responsibility. As the industry continues to explore timber applications, long-term durability and informed material selection remain key considerations.  

Working alongside architects and contractors, RESAWN partners throughout the design and construction process—providing both thoughtfully developed wood products and the technical guidance to support them. We work closely with project teams to inform specification decisions and ensure alignment between solid wood cladding systems and the broader building assembly. 

By addressing material selection, detailing, and constructability early in the project process, we help teams navigate performance requirements, streamline installation, and reduce risk in the field. This integrated approach ensures that both the cladding and its supporting systems work together to meet durability, fire, and long-term performance goals. 

Designing with intention means looking beyond the structure itself—considering how each system component and layer of support contributes to the building’s overall lifecycle, performance, and impact.

What Are Wood Flooring Mockups?

By Erin Figueroa In Featured In The News, Flooring, Mockup Program, Wood University /   No Comments

A flooring mockup is a realistic preview that shows what a specific flooring product will look like once it’s installed in an interior setting. Instead of relying on a small hand sample or imagining the finished result, a flooring mockup lets you see the color, grain, finish, and overall tone of the material “in place” on a styled surface.

Flooring mockups are commonly used by designers, builders, and architects to compare product options side by side, visualize how a floor will interact with surrounding elements, and make confident, well-informed decisions when specifying wood flooring. A physical mockup helps confirm how a material interacts with the project environment—especially under varying lighting conditions, both natural and artificial, and in combination with other finishes— so expectations are set early, and approvals move forward with confidence and clarity.

While digital visualizations can be helpful during the design process, they can’t fully replicate real-world variables like natural daylight shifts, interior lighting temperatures, surrounding paint colors, and the natural variation found in wood. A physical flooring mockup provides the most accurate avenue to evaluate a product before ordering, minimizing surprises once materials arrive onsite.

Why Are Wood Flooring Mockups Used? 

Wood is a natural product, with character varying from board to board. A hand sample may show tone and texture, but never fully captures the full range of variation within a finished flooring installation. Mockups provide a larger, more representative view, so specifiers can review a species’ color variation, finish, and how the flooring material responds to project-specific lighting and color.

Selecting the right wood species and finish plays a major role in the long-term durability and maintenance of a wood floor. Each species varies in hardness, grain structure, and resilience, which affects how well the floor holds up to everyday wear. Harder woods tend to resist dents and surface damage more easily, while softer species may show character marks over time.

To help architects and designers specify wood flooring with confidence, reSAWN’s flooring mockups provide an accurate way to evaluate species, color, grain, and finish before materials arrive onsite. By seeing the material in a larger format, you can validate overall pattern, tone, movement, and sheen, so what you choose is what you can expect in the finished space.

Flooring mockups are available for all our solid and engineered flooring products, including our collection of FloorScore® Certified European White Oak and Black Walnut products.

reSAWN’s Flooring Mockup Program

We offer three standard mockup options to meet a range of project sizes:

  • Small Mockup: Recommended for projects 1,500 – 5,000 sq. ft. Includes (5) 24” boards.

Wood Texture and Finish for Modern Architecture with Timeless Appeal

By Devon Maurer In CHARRED WOOD, Exterior Cladding, Featured In The News, Inspiring Designs, Interior Cladding, Low Maintenance Finishes, New Products, Product Updates, Sylva, Thermally Modified Wood, Wood University /  1 No Comments

Exploring the evolution of wood in design is an exercise in exploring the history of humanity itself. Through centuries of civilization, from the earliest forms of shelter to architectural marvels of Ancient Greece and Rome, wood has been an enduring, versatile material sparking constant innovation.

Once purely functional, wood has evolved into an outlet of artistic expression for today’s architects and designers. Beyond its structural properties. wood is now a medium for creating aesthetic appeal and bringing unique personality and perspective to a space.

That philosophy is at the heart of Sylva™, our thermally modified red oak products that combine durability, sustainability, and artistry—now expanded with eight new products featuring innovative textures and finishes.

Natural Beauty Meets Design Innovation

In its raw form, wood is already visually compelling, offering warm hues, organic patterns, and distinctive grain structures unique to each species. The choice of cut and milling approach, from the dynamic, cathedral patterns of plain sawn boards to the uniform, linear grain of rift and quarter sawn, shapes its personality, while textured finishes further enhance these qualities to create depth and contrast.

How Texture Shapes a Space

Wood texture is a sought-after statement that offers a tactile experience and plays a pivotal role in conveying character in a space. Texture can be achieved through different methods that influence style and durability:

  • Brushing

Brushing gently removes soft surface fibers, emphasizing denser grain beneath. This method accentuates the character of the wood, creating an interplay of light and shadow. Through this process, finishes can absorb more readily into the wood, enhancing grain contrast to deliver rich color variations.

Each new Sylva product features an aggressively brushed surface that amplifies the natural, unique grain structure inherent to red oak for a bold, textured appearance. The open grain allows finishes—ranging from rich black and cool grays to warm, natural hues—to penetrate the wood deeply, producing a saturated, dimensional color that maintains design integrity over time.

  • Shou Sugi Ban

Shou Sugi Ban, or Yakisugi, is an ancient Japanese technique that preserves wood by burning its surface, then cooling and finishing it with natural oil. The result is a uniquely rich texture and striking black carbon layer that resists moisture and decay. Brushing and Shou Sugi Ban each accentuate the beauty of wood in their own unique way. They can be used independently, or combined for added depth and dimension. Depending on the degree of brushing, Shou Sugi Ban can retain a heavy, tactile char layer, or reveal the natural grain beneath for a bold or refined aesthetic.

Color and Tone in the Built Environment

Research in environmental and color psychology has shown that color significantly affects human behavior and perception. Warm tones are linked to feelings of comfort, safety, and a sense of connection, while cooler tones offer balance and refinement, with hues that evoke calmness, serenity, and spaciousness. Dark or blackened finishes introduce a layer of richness and depth, with tones that communicate elegance and drama and can anchor a design to provide visual weight and contrast.

Our eight new Sylva finishes span this spectrum – from a light, airy gray that opens a space, to warm, inviting browns and a deep black offering drama and sophistication, each finish is carefully crafted to appeal to any design aesthetic.

Acetylated Wood: Performance-Driven Timber for Exterior Applications

By Devon Maurer In CHARRED WOOD, Exterior Cladding, Featured In The News, Wood University /  3 No Comments

With an increased industry focus on sustainability and product performance, wood continues to be the building material of choice for durability, stability, and eco-consciousness. No other resource captures a unique warmth and beauty while providing the high-performance and adaptability sought after by architects and builders.

While the benefits of wood as a building material far outweigh the cons, natural wood is susceptible to vulnerabilities like moisture, rot, and decay. However, by modifying the wood, these vulnerabilities can be offset to enhance the durability and dimensional stability of wood without compromising its natural beauty or environmental friendliness.

What is Modified Wood?

Wood modification involves the application of a chemical, physical, or biological agent upon the wood to alter the cellular structure and enhance performance. Modified wood is stronger and more resistant to decay through reduced water absorption and expansion/contraction. There are a variety of modification techniques, including thermal modification, chemical modification, and furfurylation, which is a combination of both thermal and chemical modification. This article will focus on the benefits of chemical modification – or acetylation – a chemical reaction that has been used for over 100 years and turns softwood into hardwood by preventing the cells in the wood from absorbing water.

Acetylation: Chemical Modification of Wood

Acetylation is the most established, proven, and effective form of chemical wood modification. Unlike pressure treatment, which forces chemical preservatives into the fibers of the wood in a pressure chamber, acetylation chemically alters the biological structure of the wood.

The Acetylation Process

During the acetylation process, the wood is subjected to an organic reaction with acetic anhydride – a clear, colorless liquid with a strong scent of vinegar (essential, vinegar without the water.) Acetic anhydride reacts to a part of the wood’s cellular structure called free hydroxyls, which allow the absorption and release of water in and out of the wood. The acetylation process converts free hydroxyls into acetyl groups, which water can no longer bind to, significantly reducing the ability of the wood to absorb and retain water.

Wood Selection

Accoya® Wood is the leading example of chemically modified wood, utilizing a cutting edge, proprietary acetylation process. The acetylation of Accoya yields exceptional results for demanding exterior applications like cladding, decking, and more. The processing of producing Accoya begins by responsibly sourcing radiata pine, a high-yield, fast-growing softwood species. Accoya wood is FSC®-Certified, protecting local biodiversity and habitats through a sustainable timber supply chain.

Acetylation Reaction

Once sourced and milled, the wood is subjected to a chemical reaction with acetic anhydride, which occurs in a high-temperature, high-pressure environment, typically around 120° Celsius (248° Fahrenheit). During this phase, the hydroxyl groups (-OH) on large molecules such as lignin and hemicellulose in the plant cell wall react wiht the acetic anhydride and are replaced by acetyl groups (-COCH3).

Accoya Modified Wood Acetylation Process

Post-Reaction Processing

After the acetylation reaction, the wood undergoes washing and drying to remove residual chemicals and by-products; the finished product is completely non-toxic and certified safe for humans, animals, and the environment.

The resulting acetic acid from the reaction is recovered and purified through a distillation process, which is then recycled back into the acetylation process, effectively regenerating acetic anhydride. This closed-loop system not only reduces the consumption of raw materials, but minimizes the environmental impact associated with the production and disposal of chemicals.

Lumber Milling: A Guide for Techniques & Cuts in Architectural Design 

By Jocelyn Mahan In Featured In The News, Flooring, In the Field, Interior Cladding, Wood University /  2 No Comments

Lumber milling is an age-old craft that merges wood’s natural beauty with the functional needs of architecture and design. Each milling cut offers a unique intersection of form, grain pattern, and structural properties that dictate aesthetic appeal and practical utility. Understanding these techniques is key to maximizing wood’s potential, from the versatile efficiency of plain sawn boards to the dimensional stability of rift and quarter sawn cuts. 

With the resurgence of natural materials in present-day architecture, the choice of milling techniques plays a critical role in achieving specific design aesthetics and performance outcomes. Whether for flooring, wall cladding or structural components, knowing the distinct qualities of each cut allows designers, builders, and architects to make informed decisions. 

This article explores the distinctions of lumber milling, demystifying key terms and revealing the artistry behind sawyers’ choices. 

Plain Sawn: Efficiency Meets Visual Appeal 


Plain (or flat) sawing is the most efficient and common milling technique. In this process, the sawyer aligns the first cut parallel to the curvature of the log. Then, they keep cutting the wood, switching between going the same direction as the log and across it, until they reach the middle. 

Characteristics and Advantages:

  • Efficient & Cost-Effective: This method maximizes the number of boards that can be milled from a single log, reducing waste and making it the most affordable option. 
  • Aesthetic Appeal: Plain sawn boards display a distinctive “cathedral grain” pattern, giving wood surfaces a natural, dynamic look. 
  • Readily Available: Due to its widespread use, plain sawn lumber is one of the most accessible options on the market. 

Applications: 

  • Flooring & Millwork: WESTPORT Select Plain Sawn North American Black Walnut offers tonal uniformity and clarity, enhanced by the cathedral grain for an elegant look. 
  • Cladding: Products like ARDMORE utilize plain sawn material for a more monotone application, while HOWAITO leverages grain variations to create a lively tonal interplay. 

Live Sawn (Original Cut): The Most Resource-Efficient Approach


Live sawn, or original cut, is a milling technique that produces the widest boards possible from a log by making parallel cuts from top to bottom. This method captures the entire cross-section of the log, resulting in a unique blend of cathedral grain, vertical grain, medullary rays, and sapwood within a single board. 

Key Visual & Structural Elements:

  • Cathedral Grain: Found in the outer sections of the board, adding a dramatic and sweeping aesthetic.
  • Vertical Grain: Visible in the inner sections, offering a more linear and structured appearance.
  • Medullary Rays: Radiating from the log’s center, these unique flecks or streaks are highly prized in species like oak.
  • Sapwood Contrast: The lighter outer layer of the log creates natural visual interest against the heartwood.

Benefits of Live Sawn Milling: 

  • Minimal Waste, Maximum Sustainability: Because the entire log is used, this method supports sustainable forestry practices by increasing overall yield. 
  • Superior Stability: The variety of grain orientations within a single board improves dimensional stability, reducing the likelihood of warping. 
  • Organic Aesthetic Appeal: Live sawn boards feature a striking mix of grain patterns, making them ideal for bold, naturalistic designs. 

Applications: 

  • Flooring: Live sawn products like European White Oak are a popular choice in rustic and contemporary interior designs. 
  • Architectural Elements: Suitable for feature walls, beams, and ceilings where natural character is desired.

Rift Sawn and Quarter Sawn: Precision and Stability 


The rift and quarter sawn milling methods are often misunderstood in woodworking. The key difference lies in the angle of the tree’s growth rings relative to the board’s surface, as seen from the end of the cut. 

Quarter Sawn: 

  • Growth rings are at an angle of 60 to 90 degrees to the surface. 
  • Creates straight grain patterns and often showcases medullary rays, which appear as flecks or ribbons, adding a unique visual element to certain species like oak. 
  • Higher resistance to moisture absorption, making it more stable than plain sawn lumber. 

Rift Sawn: 

  • Growth rings are at an angle of 30 to 60 degrees to the surface. 
  • Produces a clean, straight grain with minimal variation and no visible medullary rays. 
  • Highly sought for precision applications such as fine furniture, cabinetry, and architectural millwork. 

Milling Process: 

  1. A log is first cut into four quarters (cants). 
  2. Each quarter is then sliced parallel to its flat face, with the sawyer turning the cant 90 degrees after each cut. 
  3. The first, wider cuts become quarter sawn boards, while the smaller cuts with a lower grain angle become rift sawn boards. 

Advantages of Rift and Quarter Sawn Milling: 

  • Dimensional Stability: The perpendicular grain alignment minimizes expansion and contraction due to humidity changes. 
  • Durability: Less prone to warping and cupping, making it ideal for flooring and high-end woodworking projects. 
  • Refined Aesthetics: The uniform grain structure provides a sleek, modern look that suits minimalist and modern designs. 

Applications: 

  • Flooring & Cladding: Quarter sawn white oak is a popular choice for high-end installations, offering both durability and an elegant grain pattern. 

By understanding milling techniques, builders, architects, and designers can deepen their design narrative and elevate their projects with the beauty and integrity of wood. Whether emphasizing the natural grain patterns of plain and live sawn boards or opting for the structural reliability of quarter and rift sawn lumber, each cut offers unique advantages.

Engineered vs Solid Wood – Choosing the Right Flooring

By Jocelyn Mahan In Featured In The News, Flooring, In the Field, Inspiring Designs, Wood University /   No Comments

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.

Field Mockups: A Key Tool for Accurate Building Design and Execution

By Blake Huang In Featured In The News, In the Field, Inspiring Designs, Wood University /  1 No Comments

Climate is a diverse and beautiful factor that significantly influences building design. Elements such as temperature, humidity, wind, and precipitation shape a structure’s aesthetics, functionality, construction process, material choices, and longevity. With rising construction costs, even minor errors can significantly impact a project’s budget and timeline. Ensuring precise execution is particularly critical for exterior building materials that protect a structure from the natural elements. Field mockups for exterior wall assemblies are essential tools to verify material selection and construction techniques before the project begins.

What is Field Mockup?
A mockup is typically a smaller-scale representation of the actual building, designed to mimic the building’s structure and construction. Field mockups are typically placed at or near the construction site. They provide a tangible, three-dimensional representation of a design, allowing architects, designers, contractors, and owners to assess functionality, aesthetics, and quality before full-scale production.

Why Use Field Mockups?
A mockup is useful for evaluating the integration of construction systems and the performance of materials. Each structure and location are unique, and with countless building material options available, BIM or CAD detailing cannot address field-dependent variables as effectively as a full-scale field mockup for exterior wall systems. Moreover, when working with natural materials like wood, climate plays a large role in shaping how the wood weathers. Mockups help verify the material’s suitability for specific climatic conditions and ensure quality construction. By simulating real-world conditions, mockups deliver many benefits to the architects, contractors, owner, and stakeholders:

  • Weathering Observation: Monitor how materials weather over time.
  • Product Appearance: Evaluate the appearance of materials over a larger field.
  • Confident Material Specification: Ensure the chosen product suits the specific exterior conditions of the construction site.
  • Wood Movement Tolerance: Assess wood movement in the project-specific climate.
  • Ventilation & Drainage Effectiveness: Monitor the effectiveness of rear ventilation and drainage through assembly details (e.g., rainscreens).
  • Construction Best Practices: Serve as a teaching tool for trade partners, promoting efficient and accurate practices during constructions.
  • Stakeholder Review: Enable stakeholders to observe and assess the weathering process of materials and construction structures, helping to set expectations and facilitate stakeholder approval.

reSAWN’s Mockup Program
At reSAWN TIMBER co., we are dedicated to delivering exceptional results and ensuring complete satisfaction. We offer a mockup program and always encourage our clients to take advantage of a field mockup. Certain reSAWN products require a field mockup prior to full ordering.

When possible, mock-ups should be installed well before materials are delivered to the project site (8-16 months in advance) to allow the materials to acclimate and weather according to the region’s climatic conditions.

The Art and Functionality of Slats in Architectural Facade Design

By Jocelyn Mahan In Abodo Vulcan Slats, Featured In The News, In the Field, Inspiring Designs, Wood University /   No Comments

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. By embracing the potential of slats, architects can design buildings that are not only beautiful but also environmentally responsible and adaptable to the needs of their occupants.
