Characteristics of fixed fireproof glasses

  • Frame with internal insulation composed of inorganic silicate materials and, above all, without asbestos. The load-bearing profile of the frame is made of cold-formed tubular steel.
  • The false frame is made completely in a galvanized tubular pipe.
  • The window thickness is available in sizes 50 mm (EI2 60) and 80 mm (EI2 120), with the possibility of adding a fireproof glass (supplied disassembled). The latter comprises extra clear slabs, among which there is an intumescent material that favours insulation and ensures perfect fire protection.
  • Thermo-expanding gaskets are positioned along the entire external perimeter. On request, stiles and rails can also be installed.
  • RAL powder coating, with GRAY RAL 7035 colour as the standard one.
