= Cross Laminated Timber
Elements are made up of at least 3 layers of timber lamellae that are arranged perpendicular to each other and then glued together under high laminating pressure to form large-format structural solid wood panels. The transverse arrangement of the lamellae increases the load-bearing capacity and dimensional stability of the structural timber elements, whilst the impact of swelling and shrinkage is reduced to an insignificant minimum.
Developed in 1995 at the Technical University in Graz, Austria, CLT has developed into an internationally strong building material with exceptional building capabilities and characteristics.
STRENGTH AND STABILITY
Cross lamination provides superior dimensional stability and shear strength performance at a very unique weight to strength ration compared to other common structural materials.
THERMAL PERFORMANCE
CLT are better insulators, requiring little to no insulation. The solid panels have nearly zero air infiltration into the building envelope. This has a big impact on heating and cooling costs.
FIRE RESISTANCE
A thick cross-section provides valuable and superior fire resistance for a CLT panel. Their mass means they char slowly, slowing and eventually stopping combustion. In an event of fire, CLT structures suffer less degradation than concrete and steel.
MOISTURE MANAGEMENT AND VAPOR DIFFUSION
Wood is naturally hygroscopic, serving as a moisture management system within a building envelope. The wood's ability to absorb and emit moisture can naturally stabilize an indoor environment. CLT buildings breathe, which minimizes the risk for mold growth and maximizes the comfort of its occupants.
ENVIRONMENTAL BENEFITS
Wood is the only major building material that grows naturally and is renewable. CLT has a lighter carbon footprint as wood products continue to store carbon absorbed by trees while growing. Also, engineered wood manufacturing requires significantly less energy to produce than concrete and steel.
HEALTHY INDOOR ENVIRONMENT
The only constituents of a CLT building system are wood and a non-toxic/non-VOC adhesive. CLT building materials do not introduce any toxins into the indoor environment providing clean indoor air quality.
LIFE CYCLE ANALYSIS
The longevity of CLT components ensures that the future value of any structure remains high. CLT buildings are fully recyclable once they reach the end of their useful life.
DESIGN FLEXIBILITY
CLT has unique structural properties that provide increased design flexibility, allowing for distinctive and innovative projects.
