National Gypsum's Gold Bond High Strength Fire-Shield Gypsum Board is a 5/8 in. Type-X wall and ceiling panel designed for interior applications that demand both fire resistance and superior durability. Featuring a high-density, reinforced gypsum core, this board provides enhanced impact resistance and sag control while meeting ASTM C1396 specifications for fire-rated construction. It performs reliably in assemblies requiring a one-hour or greater fire rating, making it suitable for commercial, institutional, and multifamily projects. The dense composition improves surface hardness, reducing surface damage in high-traffic areas such as corridors, stairwells, and utility spaces. Encased in 100% recycled face and back paper, National Gypsums Fire-Shield board also supports environmentally responsible design and contributes to GREENGUARD Gold Certified indoor air quality standards. Easy to score and snap, it installs efficiently with standard drywall tools, offering a balance of strength, safety, and code compliance for demanding interior wall and ceiling systems.
