Evidence shows that wood is a durable, high-performance material. Examples of wood buildings that have stood for centuries still exist all over the world. Mass timber products such as cross-laminated timber (CLT), and nail-laminated timber (NLT), are enabling increased dimensional stability and strength, and design versatility to enhance project detailing.
Durability is defined as the ability of a building or any of its components to perform the required functions in a service environment over a period of time without unforeseen cost for maintenance or repair.
Extensive research and documented experience have led to a number of proven strategies for ensuring that wood material reaches its full potential for longevity.
Using durable materials in tandem with an appropriate envelope design can result in significant savings in terms of reduced-cost maintenance and repairs later in a building’s life.
