The Frinorm standard frame extension elements for aluminium windows are suited for high thermal insulation requirements. The aluminium shell is purely mechanically mounted. Due to the high expansion coefficient of the aluminium, the aluminium shell is only clamped into the guide groove. The aluminium shell is available for one or both sides from Frinorm or on site. All RAL and NCS colours are available. The standard frame extension elements are available with chipboard P5, E1, untreated, or plywood panel AW100. PUR rigid foam, 32 kg/m³, or expanded polystyrene rigid foam with graphite additive (EPS lambda), 25 kg/m³, is used as standard for thermal insulation. Other types of thermal insulation, such as glass wool, are also available. The frame extension elements are fabricated with a circumferential spruce pine edge band. Special edge bands can be inset according to your requirements.
