Pyro-Guard is pressure-impregnated, interior fire-retardant treated lumber and plywood for enclosed structural applications.

Pyro-Guard is the only major fire-retardant formulation produced by an American-owned company.

Fire Performance
Pyro-Guard is pressure impregnated deep into the wood to provide permanent protection, unlike coatings, which only provide superficial protection.

When Pyro-Guard treated wood is exposed to fire, non-combustible gas and water vapor are produced, and a layer of protective char forms, which hinders combustion and insulates the wood against further damage.

Pyro-Guard interior fire-retardant treated wood has a low rate of fuel contribution and heat release, and it maintains structural integrity longer than other building materials such as steel. Consequently, fire damages and repair costs are minimized, resulting in reduced insurance rates.

Pyro-Guard meets the flame spread requirement of all building codes which is 25 or less, as determined by Underwriters Laboratories in the extended 30 minute duration of ASTM E-84, "Standard Test Method for Surface Burning Characteristics of Building Materials." Each piece of treated wood bears the Underwriters Laboratories Classification mark identifying it as being produced under its Classification and Follow Up Services.

Pyro-Guard should not be confused with fire-retardant surface coatings, because test requirements and code definitions are entirely different for each. Pyro-Guard is pressure impregnated and carries a flamespread rating derived by Underwriters Laboratories in the 30 minute ASTM E-84 flamespread test, while coatings are sprayed, brushed or rolled on the surface and flame tested for only 10 minutes. Fire retardant coated wood is superficially protected at best, and it does not meet code requirements for structural uses.

Ideal Applications

Pyro-Guard is used for interior structural applications.

Pyro-Guard is recommended for enclosed structural applications such as:

Plywood roof sheathing
Roof trusses
Rafters
Floor joists
Mezzanines
Shelving
Load-bearing walls
Floor sheathing
Partition walls
Studs
Interior beams
Blocking
Steps
Stairways
Platforms
Stages
Plywood subfloors
Wall sheathing
Telecomm/electrical panels

Physical Properties

Pyro-Guard has been strength-tested after prolonged exposure to elevated temperatures and moisture to verify its strength characteristics when used in roof systems and other recommended applications.

Flame spread classes, roofing classes and hourly ratings are confusing terms and they sometimes get misused. The first is based on the ASTM E-84/UL 723 "Test for Surface Burning Characteristics of Building Materials." The second is based on ASTM E-108/UL 790, "Test for Fire Performance of Roofing Materials." The third is based on ASTM E-119 "Fire Tests of Building Materials."
