The key unique advantages of this standard fire-resistant gypsum board include its 1-hour passive fire resistance per ASTM E119 standards, which provides critical extra time for occupants to evacuate and first responders to contain fires. Its tapered beveled edges eliminate the need for additional joint compound buildup to create a seamless finish, reducing installation time and material costs. The dense, uniform gypsum core ensures consistent thermal and fire performance across every sheet, while the sulfate-resistant kraft paper facing resists moisture damage and surface degradation. Third-party certified by UL, CSA, and ISO 9001, this board meets the strictest safety and quality standards for interior construction. It is compatible with standard drywall installation tools and fasteners, making it accessible for both professional contractors and DIY enthusiasts, and its low formaldehyde emission level ensures a healthy indoor air quality for occupied spaces.
This standard fire-resistant gypsum board has standardized dimensions of 2400mm in length, 1200mm in width, and 12.7mm in thickness, with a single sheet weight of approximately 24.8 kg. Its core is composed of high-purity gypsum mixed with fire-retardant additives, delivering a core density of 850kg/m³ and a thermal conductivity of 0.16 W/(m·K). The board meets the 1-hour fire resistance rating per ASTM E119, with a water absorption rate of ≤10% to resist minor moisture exposure. The facing material is sulfate-resistant kraft paper, which provides a smooth, paintable surface and protects the gypsum core from physical damage. The edge type is a 1/2-inch tapered bevel, designed to create a recessed joint for easy finishing with drywall compound. It is compatible with #6 drywall screws and standard installation tools, and holds certifications including UL Listed, CSA Certified, and ISO 9001, with formaldehyde emissions limited to ≤0.05ppm to meet E0 grade indoor air quality standards.
This standard fire-resistant gypsum board is ideal for a wide range of interior construction and renovation projects, including commercial office building interior walls and ceilings, public school classroom partitions and ceilings, hospital corridor and patient room drywall, retail store display wall framing, and residential home interior partition walls. It meets local building code fire safety requirements for non-residential and residential interior spaces, making it a versatile choice for contractors, builders, and DIY homeowners. It is particularly well-suited for high-traffic areas where fire safety is a top priority, as well as spaces where a smooth, professional finished surface is required. Additionally, its low formaldehyde emissions make it suitable for use in occupied spaces such as childcare centers, senior living facilities, and healthcare environments where indoor air quality is critical.
