Premium Ceiling Finish Material

WetAgainst’s Fiberglass Coated Veil (weighing 120g to 200g/m²) combines a lightweight design with great durability, which is perfect for commercial ceilings. Its fiberglass core with high tensile strength can resist sagging and fit curved or flat surfaces. The polymer coating can ensure a smooth matte or gloss finish. It is compatible with gypsum, mineral wool and metal substrates, and it supports heat - activated or mechanical installation to achieve wrinkle - free results. The material can bear structural loads without losing strength, and its durable surface can keep its appearance in busy areas like airports and hospitals.

36-Hour Waterproof Ceiling Defense

WetAgainst’s nano - ceramic layer, which is certified by ASTM D7793, combines with fiberglass to prevent water from penetrating for more than 36 hours. This is three times the performance of standard membranes. The hydrophobic coating can repel moisture and allow vapor to diffuse (with a perm rating of 0.15), thus preventing blistering and mold growth. It can inhibit 99.6% of bacteria, so it is perfect for pools, laboratories and food facilities. Field tests in coastal areas have demonstrated that it has 98% corrosion resistance after 5 years, which guarantees long - term protection for metal frames.

High Breathability for Acoustic Comfort

The microporous structure has an airflow of 1200L/m²/s (certified by ISO 9237). It regulates humidity and improves sound absorption (NRC 0.85). It can reduce mid - frequency noise by 18dB, which is better than traditional panels in offices and schools. The breathable design stops condensation and can cut HVAC energy consumption by as much as 22% in climate - controlled areas. Also, its non - metallic composition gets rid of the risks of electromagnetic interference, making it safe for MRI rooms and technology - intensive environments.

Class A Fire-Resistant Mold-Proof Ceiling

The core of the Fiberglass Coated Veil is naturally fire - resistant. Flame - retardant additives further enhance this property, enabling it to meet GB8624 Class A standards. It can self - extinguish when taken away from the fire source and prevent the spread of flames. In case of fires, it chars to create an insulating barrier, which slows down the spread of flames and protects public places such as hospitals and malls.
