EPiC database - Cross laminated timber (CLT)

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.

Cross laminated timber (CLT) is a manufactured timber product, similar to plywood. Solid timber members are bonded together, with the grain alternating by 90 degrees for each lamination. CLT is much thicker than traditional plywood and has superior structural capabilities. It has excellent dimensional stability, strength and rigidity.

CLT is fabricated using a range of different timber varieties. It is typically bonded together using melamine urea formaldehyde, polyurethane or other adhesives.

CLT has different structural capabilities when compared with conventional timber, and acts as a sheet product, rather than a framing product. It can be used as a complete floor, wall or roof system, without the need for additional supporting members.
