Clt Wall Panel Thickness

Widths up to 18 feet and lengths up to 98 feet are possible but uncommon.

Clt wall panel thickness.

Machine stress rated or visually graded dimensional lumber or scl dried to 12 moisture content before layup. 13800 x 3100 x 400 mm lenght x width x thickness. A common na thickness is 1 3 8 planed 2x stock prg 320 provides thickness to width requirements of laminations. The apa mark of quality.

Cross laminated timber clt panels are formed by stacking and gluing together successive perpendicular layers of wood. The layered stacks are then pressed in large hydraulic or vacuum presses to form an interlocked panel. Alternating grains improve clt panels dimensional stability. Clt sizing finished panels are typically 2 to 10 feet wide with lengths up to 60 feet and thickness up to 20 inches.

Structural composition of clt laminations. Clt wall i joist adapted from trada 2009 26. Standardized sizing achieving building efficiencies can be greatly enhanced if the project is designed from the beginning with standard crosslam clt panel sizes such as 2 4 m or 3 m by 12 19 m. The timber is strength graded to bs en 14081 1 2005 and glued together in a press which applies pressure over the entire surface area of the panel.

Board thickness typically varies between 5 8 inch to 2 inches with board width ranging from 2 4 to 9 5 inches the panels can be manufactured at custom dimensions though transportation restrictions dictate their length. Clt panels consist of not less than three cross bonded layers of timber typically ranging in thickness between 20mm and 45mm. Clt wall i joist adapted from trada 2009 27.
