Applications for Hoover Pyro-Guard Lumber and Plywood
Pyro-Guard lumber and plywood products are strength-tested after prolonged exposure to elevated temperatures and moisture, verifiying the strength characteristics of the wood for use in roof systems and other applications. Plywood span ratings and lumber design value adjustments are based on strength testing after prolonged exposure to high temperatures that you roof applications typically experience. Pyro-Guard products can also be used for ceiling and floor joists and other applications, including:
- Plywood roof sheathing
- Roof trusses
- Floor joists
- Load-bearing walls
- Floor sheathing
- Partition walls
- Interior beams
- Plywood subfloors
- Wall sheathing
- Telecomm/electrical panels
Advantages of Hoover Pyro-Guard Wood Products
- Construction with Pyro-Guard treated wood requires no special tools or skills.
- Pyro-Guard trusses and roof decks often qualify a masonry wall building as “non-combustible” for insurance purposes.
- Pyro-Guard can often be substituted for non-combustible materials without affecting building classification.
- Use of Pyro-Guard wood partitions instead of untreated partitions often allows for an increase in square footage and lower insurance rates.
- The use of Pyro-Guard wood roof decking is usually accepted in lieu of parapet walls in multi-family dwellings.
- Even when sprinklers are mandatory, the use of Pyro-Guard can further reduce fire insurance rates.
- Pyro-Guard is commonly accepted by building codes for partition walls, store fronts, fixtures and roof construction in shopping centers.
Benefits of Pyro-Guard Interior Fire Retardant Treated Wood
Increased Fire Performance without Additional Smoke Toxicity
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.
When it comes to smoke toxicity, Pyro-Guard has successfully passed a stringent combustion toxicity test. Smoke produced by Pyro-Guard treated wood was no more toxic than smoke produced by untreated wood.
Pyro-Guard was the first FRTW (fire-retardant treated wood) to be issued a Code Compliance Report based on high temperature testing for roof sheathing and framing uses.
Natural Color and Textture Retained
The natural wood color and texture remains intact with Pyro-Guard. Raised grain may occur, especially on sanded plywood, and this is easily removed by sanding. Marks may be left by drying sticks on both sides of lumber and plywood. If these are undesirable, Pyro-Guard can be ordered with stick marks on one side only.
Strength Tested for Structural Applications
Pyro-Guard was the first interior fire-retardant treatment with plywood roof span ratings and lumber strength adjustments based on high temperature testing. Plywood was strength-tested after exposure to 170 degrees F, and lumber was strength-tested after exposure to 150 degrees F according to ASTM 5516 and ASTM 5664. As a result, Pyro-Guard can be used with confidence in all recommended structural applications, including plywood roof sheathing and roof trusses.
Multiple Finishing Options
Pyro-Guard interior fire-retardant treated wood can be finished or painted. As with untreated wood, the wood must be dry and clean before finishing. Pyro-Guard fire retardant treated wood, like any other type of wood, should only be finished after the structure is enclosed and mechanical equipment is placed in service. This allows the moisture content in the wood to stabilize at an acceptable level. Coating systems should first be tested on sample material and exposed to actual use conditions to determine if the desired effect can be obtained.
Resistant to Decay and Termites
Treatment with Pyro-Guard provides excellent resistance to decay and termites. Keep in mind, however, that interior fire-retardant treated wood is not recommended for use in damp or wet conditions, or in contact with concrete slabs or soil.
Promotes Air Flow
Adequate air flow must be provided in wood roof systems to prevent moisture buildup in the wood. It is the sole responsibility of the building owner or his agent (builder, architect, engineer, etc.) to insure that ventilation is provided to at least the level required by the appropriate building code.
Low Hygroscopicity and Corrosiveness
The hygroscopicity (moisture absorbency per ASTM 3201) and corrosiveness of Pyro-Guard fire-retardant treated wood is far lower than the maximum allowed by industry and governmental standards. Even though testing indicates that carbon steel fasteners can be compatible with Pyro-Guard, galvanized fasteners are recommended. Pyro-Guard is safe to use with galvanized truss plates, duct work, plumbing, conduit, and copper. It contains no halides, sulfates, or ammonium phosphates.
