Technology

  • ELVIAL I² Insulation Technology: An additional insulation zone in the central chamber of every profile; up to a 38% gain in energy performance (Uf).
  • Insulating bars up to 42 mm: 25% glass fibre reinforced, for high insulation plus extra rigidity.
  • Co-extruded gaskets: Optimise the isothermic flow at the centre and around the perimeter.
  • Foam insulation profile: Minimises heat loss around the glass.
  • Advanced Sealing System: Triple-level watertightness with EPDM and co-extruded gaskets, vulcanised EPDM corners and "smart" clip-on end caps.
  • Durability for a Lifetime: A support that transfers the glazing load to the mechanism on the inner side of the sash, for smooth operation regardless of glass weight.
