Foamfrax® Insulation is a monolithic insulation system developed by Unifrax. Foamfrax Insulation is a three component system of specially conditioned bulk ceramic or alkaline earth silicate (AES) fibers, an inorganic binder, and an organic foaming binder.
The Foamfrax installation process combines the bulk fiber material with the inorganic and organic binders in a patented mixing mechanism. Within the mixing chamber, the fibers and binders are combined to create a homogeneous foam/fiber mixture. The Foamfrax installation machinery propels this mixture through a feed hose and nozzle, and the material is then gunned onto the target surface. The proprietary Foamfrax binder system and patented installation method completely encapsulate the fibers with the foaming binder, significantly reducing airborne fiber levels during installation. Foamfrax Grade I Insulation Fiber is a 1260°C (2300°F) Refractory Ceramic Fiber.
Foamfrax Insulation has the following outstanding characteristics:
