iLevel Timberstrand LSL beams
TimberStrand from iLevel laminated strand lumber (LSL) is made with a network of hardwood strands laminated together with a waterproof adhesive to form a single, solid piece of material.
Defects found in solid lumber have been engineered out, so it resists bowing, twisting, shrinking and telegraphing. It is an excellent alternative to traditional stave lumber or solid sawn lumber cores. Stave lumber core is manufactured using small wood blocks which can have grain and density variation, or gaps between individual blocks that can telegraph through veneer or cause warping of doors and windows.
