Cross Laminated Timber (CLT) acts as both the structural and visual element of a building. It can be used for floors, roof, and walls, truly embodying the idea of Mass Timber construction.
CLT is comprised of several layers of kiln-dried lumber boards stacked in alternating directions. It is bonded with structural adhesives and pressed to form a solid, straight, rectangular panel. CLT panels are lightweight yet strong and known for excellent acoustic, seismic, fire (yes, meets fire rating requirements), and thermal performance.
Because CLT panels arrive to the jobsite pre-cut and pre-drilled, this expedites installation/reduces labor onsite. There is virtually no waste of fiber hence the eco-friendly aspect of CLT.
Currently, 18 story CLT buildings are approved per building codes (Oregon and Washington), with the expectation of approval of taller buildings. CLT is becoming an alternate to traditional materials such as steel, concrete, and masonry and truly embodies the Mass Timber craze by using the only renewable building resource available: timber.
