Product Details
ToughRock® Fireguard C® Gypsum Board – a definitive solution for advanced interior drywall applications. Crafted with exacting standards, it’s noncombustible, tested and described in accordance with ASTM E136, making it ideal for construction requiring a high fire-resistant rating.1 Its core is a dimensionally stable compound of gypsum, strengthened with glass fibers forming a robust, fire-resistant barrier. This product adheres to the ASTM C1396 Section 5 standards and comes in two thickness variants. Choose the 1/2″ (12.7 mm) or 5/8″ (15.9 mm) gypsum board, both UL Type TG-C and ULC classified Type C.
In high-use areas like kitchens and bathrooms or anywhere subject to powerful side lighting, make the most of your ToughRock® Fireguard C® Gypsum Board by employing a skillful hand to spread a fine layer of joint compound across the entire surface. This pivotal step will soften any seam lines and guard against unwanted visual emphasis. To achieve top-notch results, it’s critical to follow the guidance detailed in the Gypsum Association guidelines (GA-214 and GA-216). These manuals are your key to a flawless finish and proficient joint treatment for your walls and ceilings.
FEATURES AND BENEFITS
- Exceptional Surface Compatibility: Accepts a wide variety of paints, textures, and wall coverings, making it ideal for any space.
- Enhanced Glossy Paint Performance: For kitchens, bathrooms, or areas with strong side light, skim coat joint compound over the surface to reduce joint photographing or highlighting.
- Reliable Joint Treatment: Follow Gypsum Association guidelines (GA-214 and GA-216) to ensure perfect joint treatment and finishing.
- Enhances Fire Resistance: UL-Classified Type TG-C with a noncombustible gypsum core reinforced by glass fibers. Tested to meet ASTM E136 standards, ensuring superior fire protection for walls and ceilings.
- Durability and Stability: The dimensionally stable core withstands tough conditions without compromising on performance.

*FIRE SAFETY CAUTION – Passing a fire test in a controlled laboratory setting and/or certifying or labeling a product as having a one-hour, two-hour, or any other fire resistance or protection rating and, therefore, as acceptable for use in certain fire rated assemblies/systems, does not mean that either a particular assembly/system incorporating the product, or any given piece of the product itself, will necessarily provide one-hour fire resistance, two-hour fire resistance, or any other specified fire resistance or protection in an actual fire. In the event of an actual fire, you should immediately take any and all actions necessary for your safety and the safety of others without regard for any fire rating of any product or assembly/system.

FAQs
While gypsum boards are stronger in one direction, for walls, they may be installed either vertically or horizontally on both wood and steel studs. If the boards are to be used in a fire rated assembly, then use the board orientation that is stated in your specific rated assembly.
