4x8 19/32 lp flame block fire rated osb hflosb58fb - Description

FLAMEBLOCK; 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.

OSB is a material with favorable mechanical properties that make it particularly suitable for load-bearing applications in construction. It is now more popular than plywood, commanding 66% of the structural panel market. The most common uses are as sheathing in walls, flooring, and roof decking.

OSB is strong and water-resistant.

OSB is considered more environmentally friendly than plywood because smaller, younger trees may be used because of the shredding process.

OSB uses a higher percentage of the tree than plywood.

OSB Oriented strand board

OSB Manufactured using wood strands and waterproof adhesives and do not contain added urea-formaldehyde resins. The wood strands are arranged in cross-oriented layers to provide strength and performance properties similar to equivalent thicknesses of plywood.
