I-Joists

Smart Products for Serious Builders

 

High-performance LP® SolidStart® I-Joists are stronger pound for pound, straighter and more reliable than traditional lumber, with reduced moisture content for floors with fewer pops and squeaks. And, because pound for pound they have a greater load-bearing capacity than sawn lumber, you can engineer the structural components of floors and cathedral ceilings with fewer pieces, saving installation and materials costs.
