CLT Suppliers

Redstone Arsenal Candlewood Suites Hotel

In the U.S., the Redstone Arsenal Candlewood Suites Hotel in Huntsville, Alabama, was the first hotel in the country built using CLT.

About CLT Panels

CLT panels are made up of three to nine layers of lumber. The layers are stacked at alternating 90° angles and are glued together with a nontoxic adhesive.

CLT wood is typically spruce, but a panel can also contain pine, fir or both.

A CNC machine is used to prefabricate panels for the construction site.

CLT Suppliers

CLT manufacturing is a small but rapidly growing industry in North America. Mass timber suppliers in the United States and Canada have been building new mills in anticipation of increased demand for CLT panels and other mass timber products.

Making the Connections

CLT panels are interconnected with long timber screws and metal hardware. Also, CLT jobs often involve glulam post and beam construction that utilizes concealed connectors. Finally, hybrid construction utilizing hot-rolled steel beams and CLT floors is gaining traction. Connections of this sort are typically made with screws driven through the steel flange into the CLT floor panel.
