Applications evaluated by ICC-ES for fire-rated sheathing that combines flame-spread and burn-through resistance to meet fire codes.
A building solution that provides strength, savings and easy installation – at an affordable price.
Combined flame-spread and burn-through resistance bolster a home’s fire resistance capabilities, improving the homeowner’s peace of mind.
Structural design values are not limited, providing more flexibility in designing wall openings, frames and bracing.
See how LP FlameBlock sheathing performs in a controlled product demonstration compared to untreated OSB.
To create a standard OSB panel, LP’s innovative manufacturing process combines wood strands oriented in cross-directional layers with waxes and resins. Then, to create LP® FlameBlock® panels, LP’s proprietary non-combustible, fiberglass-reinforced Pyrotite® treatment is added, which combines flame-spread and burn-through resistance. This creates a product that not only resists fire damage but meets code, provides design flexibility, and also offers the strength and structural integrity of traditional OSB panels.
Go to work with a building solution that meets building code requirements for fire-resistent construction while increasing structural ratings. LP® FlameBlock® is an ICC-ES evaluated component of 1- and 2-hour fire-rated wall assemblies and roof deck applications. It combines flame-spread and burn-through resistance to give your customers peace of mind.
