Hoover Pyro-Guard

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

Uses

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

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.

Pyro-Guard plywood span ratings and lumber design value adjustments are based on strength testing after prolonged exposure to high temperatures experienced in roof applications.

Pyro-Guard is used for interior structural applications such as ceiling and floor joists.
