FIREFLY Refractory Products

High performance, low thermal conductivity Refractory Thermal Insulation for all hot processes.

A range of refractory 3 dimensional products based upon inorganic minerals and fibres bonded with colloidal silica produced by a vacuum forming process and papers produced by a water based paper process. Available in board, shape and paper formats with low thermal conductivity (K value), less than 0.05 W/mK, and total immunity to thermal shock. Application temperatures up to 1600 °C depending upon the grade chosen. At densities as low as 180 kg/m3 products are available in rigid and flexible forms. All exonerated products in accordance with the European Directive 97/69EC on Classification, Packaging, and Labeling of Dangerous Substances
