PLAINTIFF'S EXHIBIT * GEORGIA-PACI F I C Fire-Block Gypsumboard COMBUSTIBLE ROOFING Plywood Sheathed Roof over G-P Fire-Block Gypsumboard COMBUSTIBLE Fire-Block Gypsumboard has been developed for application under roof coverings to act as a "Block" against fire. Its main purpose is to stop fire from burning through the roof covering and into the building. It will also contain the spread of fire which starts in the attic area of a building. Full scale fire tests have proven Fire-Block to be very effective in containing roof surface and attic fires. Tests conducted at the University of California prove that Fire-Block provides maximum protection from exterior originated roof fires. It is recommended for use in both residential and commercial construction. PRODUCT USE: It is used on roof rafters, under either strip sheathing or ply wood sheathing. It is suitable under wood shakes or shingles, or other types of roof coverings. ADVANTAGES: 1. Tests show fires take over one hour to burn through to attic when Fire-Block Gypsumboard is used under the roof covering. 2. Low cost roof protection. 3. Easily installed, cuts and nails like regular gypsum wallboard. 4. Protects roof against wind blown fire brands. 5. Can be used in attached garages to prevent garage fires from spreading to attic space over living area. 6. Can protect house from fires originating in attic. PRODUCT DATA: Thickness--Vi" Size--2x8' Edge--Square Core--Special fire resistant core with gray paper on both sides. APPLICATION: Nail directly to rafters. Long edge should be laid across raft ers, which can be spaced up to 24 inches on center. Ends of board must be on framing members. Use regular gypsum wallboard or 4d common nails. Solid or spaced roof sheath ing is to be applied over Fire-Block, nailing through the FireBlock. Use nails Vz" longer than usual. Caution: Walk on rafter supported part of roof, not on unsupported gypsumboard. SGP 0025964 -- FB-16-6/70-5 GEORGIA-PACIFIC/iGYPSUM DIVISION, P.O.
