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.
Elevate your build with a solution that helps meet building code requirements for fire-resistant construction. Evaluated by ICC-ES, LP® FlameBlock® Fire-Rated Sheathing is a component of 1- and 2-hour fire-rated wall assemblies and for use in roof deck applications. It combines flame-spread and burn-through resistance to give your customers peace of mind.
