The 4x8ft Mold-Resistant Fire-Rated Gypsum Board is a 12mm-thick drywall panel engineered for high-moisture environments and fire safety applications. Constructed with a fiberglass-reinforced gypsum core and specialized mold-inhibiting additives, this panel meets ASTM E119 fire-resistance standards (1-hour rating) and ASTM C1396 mold-resistant requirements. The water-resistant paper facing and tapered edges ensure seamless installation in bathroom walls, saunas, or fire-rated partition systems.
Key Features Of Gypsum Plaster Board
Advanced Water Resistance: Tested to withstand 72 hours of continuous moisture exposure without warping or mold growth.
Reinforced Durability: 9mm thickness balances impact resistance (15N/mm²) and lightweight design (8.5kg/m²) for easy handling.
Anti-Microbial Treatment: Silver-ion infused core inhibits bacterial growth, critical for healthcare and food service environments.
Precision Edges: Tapered long edges enable seamless joint finishing with water-resistant compound.
Functional Benefits
Structural Integrity: Maintains dimensional stability at 800°C for 90min.
Smoke Suppression: Releases <15% CO₂ during combustion (EN 13501-1).
Acoustic Enhancement: STC 52 rating when paired with rock wool insulation.
Application Scenarios
Restroom partitions in airports, malls, and office buildings
Locker room dividers in gyms or swimming facilities
