FI RESTOP0 GYPSUM SHEATHING
G-P Firestop Gypsum Sheathing is an incombust ible gypsum product with a treated core and a specially formulated water repellent paper on both sides. G-P Firestop Gypsum Sheathing meets the requirements of ASTM C79-67 as well as Federal Specification SS-L-30C, Type 11, Grade W, Class 2, including requirement for water resistance. This eliminates the need for building paper (except where required by local building code).
G-P Firestop Gypsum Sheathing is manufactured in widths 2' and 4'. The 2' wide sheathing is made with tongue and groove edges to provide a structurally strong and stable wall. V-tongue and groove edges fit snugly, minimizing wind infil tration. The 4' wide square edge sheathing applied vertically, completely eliminates the need for corner bracing. It is designed to meet racking test requirements of FHA Technical Circular 12.
ADVANTAGES
Non-Combustible! Low Cost! Only one-half the price of some competitive type sheathing. Approximately 3% installation waste and uses fewer nails.
Average house can be sheathed in about 8-man hours. Four-foot wide sheathing eliminates need for corner bracing.
Easily scored and snapped. Water resistance core and face paper.
PRODUCT USE
May be used on both commercial and residential buildings, wherever strong, stable walls are desired.
