Product Summary
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.
Construction and Materials
FlameBlock® Fire Rated Sheathing by Louisiana-Pacific Corporation is a high-performance Oriented Strand Board (OSB) engineered for superior fire resistance. This innovative product provides builders and contractors with a robust sheathing solution that meets stringent fire safety codes while offering the structural integrity expected from a premium OSB panel.
The construction of FlameBlock® Fire Rated Sheathing involves a proprietary manufacturing process. Large, precisely cut strands of wood are oriented in specific directions and bonded together with durable resins. This layered and oriented structure is what gives the sheathing its inherent strength and stability. What sets FlameBlock® apart is the inclusion of specific fire-retardant additives integrated into the wood strands and bonding resins during the manufacturing process. This additive technology is designed to inhibit flame spread and reduce smoke development when exposed to fire.
Key materials used in the construction of FlameBlock® Fire Rated Sheathing include:
- Wood Strands: Precisely cut and oriented strands of high-quality wood form the core structural component of the panel.
- Resins: Strong, water-resistant resins are used to bond the wood strands together, ensuring panel integrity and durability.
- Fire-Retardant Additives: Proprietary additives are incorporated into the wood strands and resins to impart fire-resistant properties. These additives work to reduce the flammability of the material.
FlameBlock® Fire Rated Sheathing is designed to offer significant advantages in terms of fire safety. Its performance characteristics contribute to improved building code compliance, potentially allowing for enhanced fire-rated assemblies. The product offers a combination of structural performance and fire resistance, making it a versatile choice for various construction applications where fire performance is a critical consideration.
