Pyro-Guard® Fire Retardant Treated Plywood (FRTW)

Protect your build with the industry standard in fire safety. Pyro-Guard® is a pressure-impregnated, interior fire-retardant treated plywood designed to provide structural stability and peace of mind. In the event of a fire, this advanced treatment chemically reacts to smoke and heat, significantly slowing the spread of flames and reducing smoke development.

It’s not just plywood; it’s a critical component of a code-compliant life-safety system.

Key Features & Benefits

Flame Spread Prevention: Carries a Class A (Class 1) Flame Spread Rating, the highest level of protection available for wood products.

Structural Integrity: Unlike surface-applied coatings, the pressure-impregnated treatment becomes part of the wood, ensuring it won't peel or flake off over time.

Code Compliance: Meets or exceeds requirements for major building codes (IBC, IRC) and carries the Underwriters Laboratories (UL) mark for quality assurance.

Durability: Formulated for interior applications with low hygroscopicity, meaning it won't absorb excessive moisture or cause corrosion to metal fasteners.

Ease of Use: Can be cut and installed using standard woodworking tools (though certain restrictions apply to ripping and surfacing—always check the technical guide).

Technical Specifications

Important Application Notes

Pro Tip: Pyro-Guard is specifically designed for interior, weather-protected environments. For exterior projects or high-moisture areas (like decks or siding), we recommend using Exterior Fire-X® instead.

Fasteners: Use code-approved galvanized or stainless steel fasteners to ensure long-term performance.

Storage: Always store panels in a dry, covered area to maintain the integrity of the fire-retardant chemicals before installation.
