by wing or gre cut; which, and which foam material is formed of profile materials which, for internal reasons, are formed into chambers, i.e., the flap is divided into a plurality of chambers, which are usually filled with juice to avoid unnecessary complications when extruding the profile materials.

Brain or multiple glass panes (double or triple paned glass) have been used to improve the strength of the profile member or the larger chambers of the wing section profile material by providing a reinforcing insert as a window frame or window frame.

Mego;

in the sample, direct chapping of the profile chambers of window profile materials raises technological problems (see DE 103 58 49 Al).

While the use of polyurethane tin cores (see AT 410 350 A) for the profile element used in the manufacture of window or door frames also causes difficulties for larger size elements and is not a satisfactory solution in terms of heat transfer.

US 20117001108 Al. A process for making a door or window frame incorporating a chamber into a wood profile member is filled with the chamber insulation material. In the first step, the wood allo and ~ 2 ~ panel is formed with the frame, and then the foam liquid foam is foamed into the chamber.

Therefore, it is an object of the present invention to provide a plastic profile element which at the same time satisfies the requirements in terms of heat transfer values and, on the other hand, has a high and mechanical load bearing capacity. Furthermore

an appropriate window system b and their combination, edge layout must be published in Figures 1, 2.
