Window frame extension elements for wooden and wood-metal windows, moisture-resistant and with sound insulation

Product description


The moisture-resistant Frinorm sound insulation frame extension elements are the right choice especially for high demands on moisture resistance as well as high demands on thermal insulation.


They are available with plywood board AW100, untreated, or plywood board AW100, with primer foil, or with real wood veneer in all types of wood. Depending on the sound insulation requirements, the frame extension elements are fabricated with one or two heavy bitumen foils. Glass wool, 20 kg/m3, is used for thermal insulation. The window frame extension elements are fabricated with a circumferential spruce edge band. Special edge bands can be inset according to your requirements.


All possible CNC edge profile work is performed on all sides according to your profile specifications. Special CNC processing like cut-outs, round and segment arches or surface finishing like ventilation slots or surface grooves are also possible.
