Trus Joist Industrial Applications
TimberStrand® LSL Core: Stiff, Straight and Strong.
TimberStrand® laminated strand lumber (LSL) brings these same structural benefits to architectural wood doors and windows, providing a quality that cannot be matched by the shop-grade lumber traditionally used in millwork. TimberStrand® LSL is free of knots or other defects than can cause warp in traditional lumber.
Its strength and dimensional stability makes TimberStrand® LSL a superior core material for doors, windows, and other millwork products.
