Product Information

Fiberlock IAQ 8000 is a white, dual-purpose, high-performance coating designed to penetrate and reinforce duct liner or duct board insulation materials.


It can also be used to seal unlined duct work to prevent microbial particulate from becoming airborne.


IAQ 8000 is a non-flammable, water-based formulation that forms a flexible membrane in duct liner insulation materials. It is high in viscosity to provide maximum binding ability on insulation materials.


Manufactured from premium acrylic resins to allow for optimal durability and flexibility, necessary for air duct environments. Fiberlock IAQ 8000 contains an EPA-registered fungicide to prevent mold from growing on the surface of the cured film.


Successfully tested to ASTM standard C- 411 “Hot Surface Performance of a Coating on Glass Fiber Blanket Insulation.” ASTM E-84 Class “A” fire rating. Meets requirements of NFPA 90A/90B standard.
