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 is suitable for curved or flat surfaces. The polymer coating guarantees a smooth matte/gloss finish. It is compatible with gypsum, mineral wool, and metal substrates and supports heat - activated or mechanical installation for wrinkle - free results. The material can bear structural loads without losing strength, and its durable surface can keep its appearance in high - traffic 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 penetration for over 36 hours, achieving triple the performance of standard membranes. The hydrophobic coating can repel moisture while permitting vapor diffusion (0.15 perm rating), which can avoid blistering and mold growth. It can inhibit 99.6% of bacteria, so it is suitable for pools, laboratories and food facilities. Field tests in coastal areas have demonstrated 98% corrosion resistance after 5 years, guaranteeing 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 can reduce 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. Also, its non - metallic composition 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 core of the Fiberglass Coated Veil has a natural resistance to ignition. It is enhanced by flame - retardant additives to meet GB8624 Class A standards. It can self - extinguish when removed from the fire and prevent the spread of flames. In the event of a fire, it chars to create an insulating barrier, which slows the spread of the flame and protects public areas such as hospitals and malls.
