Fire-resistant sealing foam TECHNONICOL 240

Special single-component polyurethane foam with improved fire-resistant properties

Special fire-resistant sealing foam TECHNONICOL 240 is a single-component polyurethane material that possesses a fire resistance limit of up to 240 minutes. The product is supplied in aerosol cans. It ensures great thermal and sound insulation. The sealing foam has good resistance to moisture, mold and ageing, as well as excellent adhesion to most construction materials: concrete, brick, wood, metal, etc. (excluding polyethylene, silicone and Teflon). Gets cured under influence of moisture. Does not contain substances that deplete the ozone layer of the atmosphere.

Fire-resistant sealing foam TECHNONICOL 240 is used for:

  • thermal and sound insulation of joints when assembling fire-resistant metal doors, gates, hatches, dampers and windows;
  • sealing joints between walls and floor slabs for fire and smoke protection;
  • filling voids in fire-resistant walls, partitions, etc.
