Spray on insulation

  • SpreFix G is a lightweight non-combustible material (density 45-50 kg/m3), composed of fine and airy granulate wool mixed with a two component binder, with temperature resistance up to up to 600°C which provides thermal, acoustic and moisture insulation.
  • Besideds, with fire protection spray-on application, SpreFix S offers temperature resistance up to 1125°C.
  • SpreFix G and SpreFix S are mixed in the air during application and congeals into a seamless gel-like structure when hits the surface to be insulated and/or fire protected. The surface can finally be sealed with SpreFix Seal for high-pressure cleaning purpose.
