What is DLT used for?
DLT, similar to other mass timber products, is being used for a wide range of building types from offices and schools to commercial and public buildings. Less common than other mass timber products historically, it is growing in popularity and use. It can be used as walls, floor and roof construction. Similar to nail-laminated timber, DLT panels can be used as stairs and elevator shafts as well as bent and assembled to create curved roof structures.
Similar to other mass timber products, DLT panels can be topped with concrete to form timber concrete composite (TCC), a hybrid system used to reduce cross sections, increase spans and lessen noise transfer and vibrations.
DLT can be run through a molder to produce different aesthetic and acoustic profiles—such as a kerf, chamfer, ease or square edge. Alternating patterns of lumber are used to create various aesthetic appearances. DLT panels can also accommodate mechanical services and sound absorbing insulation, neatly tucked away as part of its cut and design.
Quality control is provided by the ICC certification for the proprietary DLT in North America. The ICC report demonstrates compliance of the DLT product with the requirements of the International Building Code. The report provides structural capacities for DLT panels and shows how to calculate fire resistance ratings.
