Premium Ceiling Finish Material

WetAgainst’s Fiberglass Coated Veil (120g - 200g/m²) combines a lightweight design with great durability, which is perfect for commercial ceilings. Its high - tensile fiberglass core can prevent sagging and fit curved or flat surfaces. The polymer coating enables a smooth matte/gloss finish. It is compatible with gypsum, mineral wool and metal substrates, and supports heat - activated or mechanical installation to achieve wrinkle - free results. The material can bear structural loads without losing its 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, bonds with fiberglass to prevent water from penetrating for more than 36 hours. This is three times the performance of standard membranes. The hydrophobic coating keeps moisture away while permitting vapor diffusion (0.15 perm rating), which stops blistering and mold from growing. It can inhibit 99.6% of bacteria, so it is very suitable for pools, laboratories and food facilities. Field tests in coastal areas have demonstrated 98% corrosion resistance after 5 years, providing long - term protection for metal frames.

High Breathability for Acoustic Comfort

The microporous structure, with an airflow of 1200L/m²/s (certified by ISO 9237), regulates humidity and improves sound absorption (NRC 0.85). It cuts mid - frequency noise by 18dB, performing better than traditional panels in offices and schools. The breathable design stops condensation, reducing HVAC energy consumption by as much as 22% in climate - controlled areas. Its non - metallic composition also removes the risks of electromagnetic interference, which makes it safe for MRI rooms and technology - intensive environments.

Class A Fire-Resistant Mold-Proof Ceiling

The Fiberglass Coated Veil core has an inherent resistance to ignition. 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 and stop the spread of flames. In the event of fires, it chars to create an insulating barrier, which slows down the spread of flames and safeguards public spaces such as hospitals and malls.
