Cross-Laminated Timber
Cross-laminated timber (CLT) is a wood panel product typically consisting of three, five or seven layers of dimension lumber oriented at right angles to one another and then glued to form structural panels with exceptional strength, dimensional stability and rigidity. Since CLT panels resist high racking and compressive forces, they are particularly cost effective for multi-story and long-span diaphragm applications. Some specifiers view CLT as both a product and a system that can be used interchangeably with other wood products; it can also be used in hybrid applications. Because of CLT’s structural properties and dimensional stability, this mass timber product is well suited to floors, walls and roofs used in mid-rise construction. The wall and floor panels may be left exposed in the interior, which provides additional aesthetic attributes. The panels are used as prefabricated building components, which can speed up construction practices or allow for off-site construction.
