Gold Bond Fire-Shield Gypsum Board

Gold Bond Fire-Shield Gypsum Board

Product catalog summary
Specifications:
The document outlines specifications for fire-resistant gypsum board products, specifically the Gold Bond® BRAND Fire-Shield® Gypsum Board. These boards are designed to enhance fire resistance and comply with ASTM C 1396, type X standards. The boards are available in various thicknesses (1/2" and 5/8"), widths (4'), and lengths (ranging from 6' to 16'). Edges can be square, tapered, or beveled tapered.
Materials:
The gypsum boards have a core with additives to improve fire resistance, surfaced with paper on all sides. They are formulated to retard heat transfer and maintain structural integrity during a fire.
Installation Procedures:
Installation should follow the manufacturer's guidelines as per the National Gypsum Company "Gypsum Construction Guide." Boards should be applied first to ceilings, then walls, using the longest practical lengths to minimize joints. Proper alignment and fastening techniques are crucial to avoid defects.
Fire Resistance Ratings:
The document specifies that type X gypsum boards must provide a one-hour fire resistance rating for 5/8" boards and a 3/4-hour rating for 1/2" boards when tested according to ASTM E 119. The boards act as a natural "sprinkler system" due to their water content, which evaporates and releases steam to retard heat transfer.
Recommendations:
For enhanced fire protection, Gold Bond Fire-Shield C products include a mineral core additive that expands under heat, maintaining board integrity. These boards can also be used for column protection to delay heat transfer and prevent structural failure.
System Burning Characteristics:
According to ASTM E84, the boards have a flame spread of 15 and smoke developed of 0.
Weights:
The weights of the boards are specified as 1.9 lbs/SF for 1/2" Type C, and 2.2 lbs/SF for both 5/8" Type X and Type C.
