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) fibres, an inorganic binder and an organic foaming binder.
The Foamfrax installation process combines the bulk fibre material with the inorganic and organic binders in a patented mixing mechanism. Within the mixing chamber, the fibres and binders are combined to create a homogeneous foam/fibre 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 fibres with the foaming binder, significantly reducing airborne fibre levels during installation. Foamfrax Grade II insulation fibre is a 1649 °C refractory ceramic fibre.
Foamfrax Insulation has the following outstanding characteristics:
