Premium Ceiling Finish Material

WetAgainst’s Fiberglass Coated Veil (120g - 200g/m²) merges a lightweight build with strong sturdiness, ideal for commercial ceilings. Its high-tensile fiberglass core can resist sagging and suit curved or flat surfaces. The polymer coating allows for a smooth matte/gloss look. It works with gypsum, mineral wool and metal substrates, and supports heat-activated or mechanical fitting for wrinkle-free outcomes. The material can handle structural loads without losing toughness, and its durable surface can maintain its look in busy places such as airports and hospitals.

36-Hour Waterproof Ceiling Defense

WetAgainst’s nano-ceramic layer, certified by ASTM D7793, fuses with fiberglass to block water penetration for over 36 hours—triple the performance of standard membranes. The hydrophobic coating repels moisture while allowing vapor diffusion (0.15 perm rating), preventing blistering and mold growth. It inhibits 99.6% of bacteria, making it ideal for pools, laboratories, and food facilities. Coastal field tests show 98% corrosion resistance after 5 years, offering long-term protection for metal frames.

High Breathability for Acoustic Comfort

The microporous structure, boasting an airflow of 1200L/m²/s (ISO 9237 certified), controls humidity and enhances sound absorption (NRC 0.85). It reduces mid-frequency noise by 18dB, outperforming traditional panels in offices and schools. The breathable build prevents condensation, lowering HVAC energy use by up to 22% in climate-controlled spaces. Its non-metallic makeup also eliminates electromagnetic interference risks, making it safe for MRI rooms and tech-heavy environments.

Class A Fire-Resistant Mold-Proof Ceiling

The Fiberglass Coated Veil core is inherently fire-resistant. Flame-retardant additives boost this trait, allowing it to meet GB8624 Class A standards. It can self-extinguish once removed from fire and halt flame spread. In case of fires, it chars to form an insulating barrier, slowing flame spread and protecting public areas like hospitals and shopping malls.
