Is gypsum board fire resistant?
Yes, gypsum board is naturally fire-resistant due to its core composition of calcium sulfate dihydrate, which releases moisture when exposed to heat, slowing flame spread. For aluminum ceiling and facade systems, fire-rated gypsum boards (Class A or Class 1 fire resistance) are commonly used, achieving up to 1–2 hours of fire protection when paired with fire-resistant aluminum framing. These boards meet standards like ASTM E119 or BS 476 and comply with Singapore’s SS 532 and BCA requirements.
Our company integrates fire-rated gypsum boards with lightweight aluminum frameworks to create systems that balance safety, durability, and aesthetics. For high-risk areas (e.g., commercial buildings, corridors), we recommend 12.5mm–15mm fire-resistant boards with added glass fibers or vermiculite for enhanced performance. Aluminum’s non-combustible properties further boost the system’s safety, making it ideal for modern construction.
All our gypsum boards undergo rigorous third-party testing for fire resistance and smoke density. Contact us to design a fire-safe aluminum ceiling or facade tailored to your project’s needs!
