[h=2]Cross Laminated Timber (CLT) Benefits[/h][h=3]Strength[/h]
Due to its amazing strength properties, CLT can be utilized in applications such as high-rises that wood has previously never been adequate for. The high strength properties have more benefits than just being able to build higher and make longer spans, they are evident in all the other amazing advantages CLT has. Any weakness in the individual stick of lumber is cancelled out by the cross lamination with other pieces until there is a single timber panel with uniform strength properties closer to reinforced concrete than wood. Lastly, cantilevers and loads can be designed in any direction rather than just one, offering exciting new design possibilities.
[h=3]Fire[/h]
The fire performance of CLT is better than any other wood building system. The low surface area and the airtight environment compared to standard wood construction also helps to inhibit fire growth in a contained space by limiting the available fuel. Even a normal installed panel does not allow fire to burn through which encapsulates the flame in a single area, suffocating it. Another great attribute is the solid thermal mass. This allows one side of the panel to be close to 1000 degrees Celsius while the other side is room temperature.
[h=3]Seismic[/h]
CLT is immensely strong, ductile, and light; the perfect attributes for an earthquake-proof building system. Seismic tests prove that CLT buildings can handle the world’s strongest earthquakes with no loss of life or structural damage. The high strength-to-weight properties decrease the seismic forces acting against the structure, making these buildings extremely safe while simultaneously allowing for smaller foundations. A 7 storey CLT building was shaken by the world’s largest shake table in Japan by 10 earthquakes and survived perfectly intact. CLT floor spans in a theoretical 24 storey high-rise have shown to reduce seismic load by 50% compared to reinforced concrete.
[h=3]Acoustic and Vibration[/h]
When replacing stick-frame walls, solid timber gives a massive upgrade in acoustic performance. CLT construction gives the home an airtight enclosure of solid mass elements, and with the proper design can satisfy the strictest acoustic ratings even in multi-storey residential buildings.
[h=3]Thermal Insulation[/h]
CLT is perfectly suited for passivhaus designs that are so efficient at insulating a home they don’t need any heating systems. The airtight environment doesn’t allow heat to leave through cracks, while the average home has cracks that add up to the size of a basketball. The high thermal mass of the timber also helps keep the interior temperature stable throughout the day – warm in the day, cool at night.
[h=3]Durability[/h]
Due to the cross laminated engineering, CLT has much better durability characteristics than solid wood. Long-term movement by the wood itself due to swelling, shrinkage, warp, and creep has been minimized to insignificant levels even for the tallest applications, opening up new frontiers for wood construction. Our product is tested constantly to ensure long-term lamination quality.
[h=3]Installation Efficiency[/h]
CLT adds tremendous value to underutilized lumber components by assembling them into precisely-machined building components. The assembly line method of manufacture maximizes efficiency off-site and minimizes the steps necessary to build a structure. We minimize the amount of transportation and manipulation necessary to extract maximum efficiency from the construction process. We simplify the assembly by lowering each panel and screwing it in place with just a few labourers in just 20 minutes. Erecting the shell of an entire house can take as little as 8 hours! Not only is it much safer to do, but it eliminates the waste from fine-tuning, squaring, cutting, and garbage disposal. All this amounts to the major benefits of completing the project in a fraction of the time it would normally take, making it more profitable, easier to estimate, and less risky for the workers, developers, owners, and investors.
[h=2]Cross Laminated Timber (CLT) Benefits[/h][h=3]Strength[/h]
- Allows wood to be used in never before seen buildings like 30 storey high rises
- Cross lamination creates perfectly uniform strength properties like steel and concrete
- Creates new possibilities in cantilevers and load bearing

[h=3]Fire[/h]
- Low surface area doesn’t sustain a flame so fires burn themselves out
- Airtight construction lowers the fires’ oxygen supply, gas does not travel through the panel
- Heat does not conduct from side of the panel to the other

[h=3]Seismic[/h]
- Combination of strength, ductility and light weight form the ideal earthquake-proof system
- Shake table tests up to 7 storeys prove that CLT buildings have excellent performance
- No loss of life or structural damage even against the strongest earthquakes

- Ideal building system for Passive Homes - that don’t require heating systems
- Can trap 90% of the heated air that escapes from normal homes
- High thermal mass of timber keeps home warm in the winter and cool in the summer
