LP SolidStart

A Perfect Fit

How LVL Is Made

LP® SolidStart® LVL is a strong, straight and durable framing product made for superior performance. It can be used in place of traditional lumber for greater consistency and design flexibility. Advantages include:

  • Ultrasonically graded veneers are arranged in specific patterns to maximize strength and stiffness
  • The veneers are bonded with exterior-grade adhesives under pressure and heat, resulting in low moisture content for dimensional stability

How LSL Is Made

LP® SolidStart® LSL’s manufacturing process provides superior performance with less shrinking, warping and twisting.

  • Made from a mix of sustainably harvested aspen and maple hardwoods for greater strength
  • A steam injection press results in low moisture content (7%–10%) similar to the conditions inside a home
  • End- and edge-sealed to reduce swelling
