GRECHO Fiberglass Coated Veil is crafted to endure long-term UV exposure, far surpassing the standard 3-month industry benchmark for insulation facings.
Tested under ASTM G154 (QUV accelerated aging):  It retains structural stability with no chalking, yellowing or strength degradation after 6,000 hours of UV irradiation, equivalent to over 6 years of service in high-altitude areas.
Reflective surface technology​​: It lowers heat absorption by over 85%, avoiding thermal deterioration of PIR, rockwool panel and glass wool insulation cores.
Ideal for solar-exposed applications​​: Ideal for roofing, facades and industrial insulation used in high-UV regions like mountainous areas, deserts and tropical climates.

Ordinary Rockwool Veil facings tend to deteriorate in wet conditions, while GRECHO’s coating delivers long-lasting moisture resistance.
Hydrophobic nano-coating​​: Features a water contact angle over 110°, blocking water absorption and inhibiting mold growth on Rockwool panels and Glass Wool Insulation.
Tested per EN 1928​​: Endures 6 hours of continuous water exposure with no leakage, perfectly suited for roofing, cold storage and underground insulation.
Seamless protection​​: Firmly adheres to insulation cores, closing all gaps to stop water infiltration.

Safety is non-negotiable. GRECHO offers ​​flexible fire ratings​​ to meet project requirements:
B1 (Flame-Retardant)​​: Low smoke, self-extinguishing—ideal for ​​commercial buildings and HVAC systems​​ using ​​Rockwool panels​​ or ​​Glass Wool Insulation​​.
A1 (Non-Combustible)​​: Zero flame spread—mandatory for ​​tunnels, high-rises, and industrial facilities​​.
Third-party certified​​: All fire ratings are verified by ​​EU Notified Bodies​​ (e.g., CE Marking).

Traditional ​​Rockwool Veil​​ facings delaminate at high temperatures—GRECHO's ​​stays intact​​:
Stable up to 200°C​​: Perfect for ​​hot pipes, industrial equipment, and solar panel backing​​ with ​​Rockwool panels​​ or ​​Glass Wool Insulation​​.
No thermal warping​​: Maintains adhesion even under rapid temperature swings (tested per ISO 6722).

Compatible with all major insulation cores​​: PIR, ​​Rockwool panels​​, ​​Glass Wool Insulation​​, and fiberglass.
Works with standard lamination methods​​: Flame-bonding, adhesive, or mechanical fixing.
Eliminates secondary coatings​​: Saves ​​15–20%​​ in material and labor costs vs. painted/aluminum facings.
