Consistent Performance, Every Time
You can use LP® SolidStart® LSL (Laminated Strand Lumber) anywhere you can use traditional lumber.
The difference: you may not need as much of it. Its enhanced strength lets it span greater distances. And LP SolidStart LSL resists twisting, warping and shrinking, so you don’t need to assemble built-up headers or beams.

LP SolidStart LSL reduces waste twice: you won’t need to cull pieces on the jobsite. And LP SolidStart LSL is made from sustainably harvested trees, using every part of the tree in the manufacturing process. It’s conservation for the environment and your bottom line.

The trees used for LP® Engineered Wood Products can be replanted and reharvested in just 25 years.
