1-Sided vs. 2-Sided LP® FlameBlock® Panels
Helping Prevent Row Home Fires
Putting Our Fire-Rated Panels to the Test
See how LP FlameBlock sheathing performs in a controlled product demonstration compared to untreated OSB.
How It’s Made
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.
Fire Resistive Technology
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-approved 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.
