Description:

The wood industry is currently trying to reduce its dependency on the

one - and two-family housing market by expanding into the nonresidential

market for wood construction. One difference between nonresidential

structures and one- and two-family dwellings is the requirement for firerated

assemblies. Fire resistance requirements have generally been met in

wood construction either by adding gypsum board as an interior finish or by

adding sacrificial wood. Another method that could be used to meet fire

resistance ratings involves the use of fire-resistive coatings. At the

present time, no commercial fire-resistive coatings are marketed in the

United States for use on wood.

A fire-resistive coating is capable of withstanding a fire and giving

protection from it. Commercial fire-resistive coatings are primarily

marketed for use on steel. Some coatings have recently been marketed as

thermal barriers for foam plastics. Coatings marketed for use on wood are

fire-retardant coatings. A fire-retardant or flame-retardant coating delays

ignition and combustion of the combustible substrate when the coating is

exposed to fire.

In this paper, I review some of the comments, ideas, and recommendations

of the April 29, 1988, workshop on the future of fire-resistive coatings in

wood construction, held at the Forest Products Laboratory (FPL) in Madison,

Wisconsin. The approximately 30 attendees represented both the wood and

coating industries as well as other interests such as testing laboratories

and insurance companies. The workshop was held in response to a recommendation

of the National Forest Products Association (NFPA).
