The Frinorm sound insulation frame extension elements for aluminium windows are especially suited for high demands on sound insulation as well as 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 sound insulation frame extension element is available with chipboard P5, E1, untreated, or plywood board AW100. Depending on the sound insulation requirements, the frame extension elements are fabricated with one or two layers of heavy bitumen foil. Glass wool, 20 kg/m3, is used for thermal insulation. The frame extension elements are fabricated with a circumferential spruce edge band. Special edge bands can be inset according to your requirements.
