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

Product description


The moisture-resistant Frinorm 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. PUR rigid foam, 32 kg/m3, is generally used for thermal insulation. Other types of thermal insulation like expanded rigid polystyrene foam with graphite additive (EPS lambda), glass wool or cork are also available. 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.
