CLT
TECHNOLOGY -
THE FOUNDATION OF FUTURE CONSTRUCTION
The construction industry today faces one of the biggest environmental challenges of our time: the steel and cement sectors alone are responsible for two-thirds of global air pollution. In an era where we aim to build faster, more precisely, and more sustainably, cross-laminated timber (CLT) may be the solution. This innovative material not only accelerates the building process, but also significantly reduces the carbon footprint of buildings.
Thanks to visionary engineers and researchers, CLT began its rise in Europe during the 1990s. Since then, it has spread across the globe and has become a preferred choice for architectural projects in the United States, Asia, and beyond.
WHY DO WE RECOMMEND CLT TO OUR CLIENTS?
Up to 10% more usable floor space
One of the unique benefits of CLT technology is that, despite the exceptional strength of the panels, it allows for thinner walls. This means up to 10% more usable interior space can be achieved within the same gross footprint. Just imagine how much of an advantage this is for smaller plots—or when a client wants a more spacious home with minimal compromise. More space without expanding the footprint? That’s the power of CLT.
Straight walls, perfect corners
The precision of CLT is remarkable. The entire construction process is supported by Builing Information Modeling (BIM), ensuring that the design is executed with millimeter-level accuracy. This results not only inperfectly straight walls and flawless 90-degree corners, but also drastically reduces the chance of construction errors. The outcome? A building that is not only aesthetically sharp but also functionally flawless.
MANUFACTURING: HOW CROSS-LAMINATED TIMBER (CLT) IS MADE
CLT manufacturing is a cutting-edge technological process that combines sustainability with engineering precision. Each step is carefully designed to meet the highest construction industry standards, while maximizing the potential of natural materials.
Premium raw material:
Spruce and more
The foundation of CLT is high-quality, selectively sourced spruce, often complemented by larch or hardwood species depending on project needs. The timber undergoes:
Drying to 12% moisture content, ensuring dimensional stability and preventing cracking.
Planing for smooth, defect-free surfaces, allowing for perfect bonding between layers.
This preparation phase is critical for both long-term durability and high load-bearing performance.
Cross-lamination: The strength of alternating layers
The defining feature of CLT panels is the cross-oriented layering, where each adjacent board is rotated 90 degrees from the previous. This layout:
Ensures exceptional load-bearing capacity in both directions.
Minimizes natural timber movements like shrinkage or expansion.
This makes CLT ideal for load-bearing walls and floor systems, where structural reliability is paramount.
Eco-friendly adhesives
The layers are bonded using formaldehyde-free, eco-friendly adhesives that contribute to healthy indoor air quality and meet the strictest sustainability standards. These adhesives are:
Durable, retaining bonding strength for decades.
Non-toxic, with no harmful emissions.
Hydraulic pressing for strength and accuracy
The layered panels are then subjected to high-pressure hydraulic pressing, which:
Guarantees precise dimensions and uniform adhesion across all layers.
Increases panel stiffness, ensuring long-term structural integrity under heavy loads.
CNC machining: Precision at its best
Once pressed, the panels are processed using CNC (computer numerical control) machines, enabling:
Millimeter-accurate openings for doors, windows, and mechanical systems.
Custom modifications to meet unique project specifications, reducing on-site work.
Surface treatment: Functional and aesthetic finishing
CLT panels are sanded and treated to:
Highlight the natural beauty of the wood grain.
Apply UV-resistant and moisture-protective coatings on visible surfaces.
Enhance fire resistance and durability even on hidden faces.
Quality control and sustainability in practice
Every CLT panel undergoes strict quality assurance, including:
Dimensional accuracy and structural testing.
Verification of adhesive bonding strength.
Any timber offcuts or waste are recycled, either into particleboard or used as biomass fuel, ensuring minimal environmental impact.
Packaging and delivery with care
Finished panels are packaged using eco-conscious materials.
Transportation is optimized to minimize the carbon footprint while ensuring that the panels arrive safely and undamaged at the construction site.
WHY CLT PRODUCTIONS STANDS OUT ?
At its core, CLT manufacturing represents the perfect blend of precision engineering and environmental responsibility. By combining modern industrial methods with the time-honored virtues of wood, CLT becomes a material that is sustainable, robust, and architecturally beautiful.
This innovative process is what makes CLT not just a smart construction choice—but a visionary one.
STRUCTURAL PERFORMANCE: THE FOUNDATIONS OF CLT LOAD BEARING AND STABILITY
Cross-laminated timber (CLT) combines modern engineering precision with sustainability and cost-efficiency. Every CLT structure is individually designed to account for site-specific factors such as wind loads, seismic activity, and other local forces—ensuring long-term durability and safety under all environmental conditions.
Built on Eurocode 5 standards
CLT structural systems are designed in full compliance with Eurocode 5, the European standard for timber structures. As a result, CLT offers:
Exceptional structural stability thanks to its cross-laminated layers, which significantly reduce the natural movement of wood.
Reliable performance under international safety codes, including resistance to seismic activity and wind pressure.
Lighter than concrete, yet incredibly strong
One of the key benefits of CLT is that it’s:
Five times lighter than concrete, while still offering comparable strength.
Load-bearing in two directions, allowing for thinner floor slabs across the same spans.
This lightweight profile reduces foundation costs and enables faster, more efficient construction on-site.
THERMAL PERFORMANCE AND ENERGY EFFICIENCY
Thermal insulation is a key element of energy efficiency—it directly impacts heating and cooling demands, reducing both operational costs and environmental impact. When designing CLT (cross-laminated timber) structures,
special attention is given to the wall buildup, tailored to the building’s function and the client’s specific needs.
This doesn’t just improve indoor comfort—it’s also a major contributor to long-term sustainability
The thermal properties of wood
Wood has excellent natural insulation characteristics, influenced by its mass, density, and moisture content. CLT structures feature a thermal conductivity (λ) of just 0.13 W/mK, which is notably lower than that of conventional Porotherm 30 N+F masonry (0.16 W/mK). This means that CLT walls offer better insulation performance at the same thickness—while remaining lightweight and structurally stable.
Layer configuration
To achieve optimal thermal performance, CLT walls can be combined with a variety of insulation systems, including EPS, XPS, mineral wool, or cellulose-based materials.
By optimizing each layer, the building’s energy demand can be minimized—while maintaining year-round thermal comfort for occupants.
Comparing insulation
CLT walls may have lower thermal mass than concrete or ceramic masonry, but this can be effectively compensated with the right insulation strategy.
Wood’s natural breathability also ensures fresh indoor air and a comfortable indoor climate—an added benefit for both well-being and air quality.
Minimizing thermal bridging
One of CLT’s standout features is its ability to reduce thermal bridging. The high manufacturing precision and tight panel joints result in airtight assemblies that eliminate common sources of heat loss. This not only enhances energy efficiency,
but also contributes to the longevity and sustainability of the structure. CLT’s thermal performance offers a combination of cost-efficiency and environmental responsibility, making it an ideal solution for both residential and industrial buildings. When paired with the right insulation systems, CLT enables the construction of low-energy, eco-conscious buildings—without compromising comfort or design
