Developed in Europe in the 1990s, CLT is the latest in engineered wood products that are strong and rigid enough to replace steel and concrete in larger, taller buildings. CLT panels consist of layers of narrow planks, about 1” thick, laid perpendicular to the preceding one. The layers are glued and the entire sandwich is pressed and trimmed. Construction using CLT panels tends to be cheaper and more environmentally friendly than other materials.
Using CNC machinery, the panels can be cut to the precise dimensions in the architectural plans, including window, door, plumbing and ventilation openings. Channels for electrical wiring can also be cut into the panels.
