Window frame extension elements for plastic windows, standard

Product description


The Frinorm standard frame extension elements for plastic windows are especially suited for high thermal insulation requirements.


They are available in unplasticised PVC in different shades of white (Veka, Kömmerling or Finstral) or unplasticised PVC with Renolit foil (all colours). Expanded rigid polystyrene foam with graphite additive (EPS lambda), 25 kg/m3, is generally used for thermal insulation. Other types of thermal insulation like PUR rigid foam or glass wool are also available. The frame extension elements are fabricated with a circumferential plywood edge band, or an edge band only on the long sides. 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.
