LP SolidStart I-JoistsLP SolidStart I-Joists make true and uniform floors and ceilingspossible for residential and commercial construction. Machinemade for precise, straight lines that stay straight, they are lighter yet stronger kilo for kilo than traditional timber joists and less likely to split, shrink, twist, warp or bow. LP SolidStart I-Joists are available in long lengths and deep depths so floors and ceilings can be designed with fewer pieces, saving installation and material costs. Builders are confident that they can offer their customers a product with exceptional performance and dependability, along with the peace of mind that comes with a Lifetime Limited Warranty when using LP SolidStart Engineered Wood Products.
