Description

Window with glare and sash frame

The invention relates to a window with a frame and a rotatably mounted in the frame sash and a profile system for its production.

Technical area

With regard to the optimization of the thermal insulation of modern windows, a considerable effort is made by the profile manufacturers. Because of their good thermal insulation, plastic hollow sections made of rigid PVC (PVC-U) have largely prevailed for highly insulated windows. In order to optimize thermal insulation, newer systems with ever-increasing depths are being used. In the meantime, depths of 70 to 75 mm have largely become standard and newer profile series with overall depths> 80 mm are available. These systems have almost without exception window frame profiles with external frame overlap and sash with internal sash overlap, both the outer frame overlap of the frame profile and the inner sash overlap of the sash profile to improve the heat insulation have at least one hollow chamber.

State of the art

To further improve the thermal insulation has been proposed to use instead of steel reinforcements for stiffening the profiles special stiffeners with lower thermal conductivity and / or additional thermal insulation in the hollow chambers, as for example in the DE 20 315 913 U1 or the DE 20 2004 012332 U1 to be discribed.

The better the thermal insulation of the profiles and reinforcements used is optimized, the more problematic the remaining thermal bridges become.

task

Object of the present invention is to improve the thermal insulation of windows according to the preamble of claim 1 further or with alternative means.

Presentation of the invention

The invention solves this problem by a window according to the preamble of claim 1, wherein the folding area in the upper horizontal and / or in the lateral window areas is at least partially blinded by a rebate insulation. This inventively used Falzdämmung preferably consists of one or more plastic profiles, which can be connected in accordance with a particularly preferred embodiment of the invention in the rebate with the frame by snapping. It is particularly preferred if the rebate insulation used according to the invention is directly adjacent to the hollow chamber of the frame overflow. As a result, an optimal coupling of the heat-insulating property of the hollow chamber of the frame frame rollover is achieved with the invention Falzdämmung.

The rebate insulation according to the invention is preferably used both in the upper and in the two lateral window areas. In the lower horizontal region of the window rebate, it is preferred to use either no rebate insulation or, in the case of center seal systems, only in the room-side rebate area of the window in order to achieve optimum drainage in the outer rebate chamber.

According to a particularly preferred embodiment of the invention, the rebate insulation is formed from Falzdämmprofilen that are mitred in the two upper corners of the window and milled in the lower corners according to the frame contour. To produce a window according to the invention is first in a conventional manner of the frame by welding at the four corners - or in windows with posts possibly by a Six-point welding - made. In Falzbereich the Falzdämmprofile invention are then glued or preferably clipped. The Falzdämmprofile can also be welded together before clipping in the corner, but they preferably encounter each other in the miter area without welding at an angle of 45 °. In the lower corners of the frame, the rebate profiles according to the invention are preferably milled in accordance with the inner frame contour so that a clean transition to the lower horizontal fold region of the frame is formed. If required, a possibly adapted Falzdämmprofil can also be used in the lower horizontal area, wherein the transition of the lower horizontal Falzdämmprofils can be done in the lateral vertical Falzdämmprofile if necessary via injection-molded fittings.

An optimum effect of the Falzdämmprofile invention is achieved at depths of the frame of at least 70 mm, in particular over 80 mm. Here is the heat loss by convective heat transfer in the rebate area in relation to the otherwise very high thermal insulation of the glare and sash profiles the clearest. The Falzdämmprofile invention can be advantageously combined with other known thermal insulation measures such as elimination of the stiffening profiles, use of thermally separated stiffening profiles, foamed or provided with foamed Einschieblingen hollow chambers, etc., wherein the percentage improvement of thermal insulation by the use of Falzdämmprofile invention is even greater.

Preferably, the Falzdämmprofile invention are made of rigid PVC (PVC-U), in particular the same material that is used for the production of the frame profiles.

The Falzdämmprofile invention can be used both in central seal systems as well as in stop seal systems. Center seal profiles often have in the rebate area of the frame profile on a central sealing dome, which is provided with a receptacle for the center seal. For this type of window, preferably two mutually parallel individual profiles are used as Falzdämmprofile, wherein both profiles are separated from each other by the dome receiving the central seal. If necessary, however, the rebate insulation profile can also be designed in such a way that it integrally spans and covers a flatter central sealing dome. In this case, the Falzdämmprofil is preferably either with its own center seal, which can be, for example, extruded equipped, or the rebate damping profile has its own center seal groove for receiving a rolled-up or inserted center seal.

The Falzdämmprofile used according to the invention have in the region of the room-side edge to a height which preferably corresponds to the height of the fitting parts used. For the fitting parts the Falzdämmprofile are preferably milled out accordingly, so that complete the fitting parts after insertion into the cutouts flush with the Falzdämmprofilen. In the case of two-part rebate insulation profiles, it is optionally possible to interrupt one of the two rebate insulation profiles for the insertion of a fitting part.

The main purpose of the invention used Falzdämmprofile is to reduce the convective heat transfer in the rebate. Preferably, the free volume of the folding area is reduced by at least 40%, preferably by at least 50%, by the inserted rebate insulation profiles.

Frame profiles are often in the area of the wall reveal by means of screws, which complete the frame profiles penetrate, fastened. A particularly advantageous effect of the invention used Falzdämmprofile is that they cover these screws and thus both visually obscure and isolate with respect to the heat conduction into the masonry.

To further improve the thermal insulation, the rebate profiles used according to the invention can optionally be subdivided into a plurality of chambers by means of corresponding webs, one or more of these chambers being able to be foamed up. The chambers of the Falzdämmprofils used according to the invention can be used in an advantageous manner as a cable channel for concealed receiving a cable for receiving a sensor or other additional function in a window or as an air-conducting element in a forced ventilation window.

An inventive profile system comprises at least one frame profile, a sash profile and at least one Falzdämmprofil, the Falzdämmprofil is preferably latched to the frame profile. As far as the Falzdämmprofil used in center seal profile systems while the center seal dome of the frame profile is covered, the invention used Falzdämmprofil preferably has its own receiving groove for receiving a center seal or alternatively an anextruded center seal.

Particularly advantageous is the use of a Falzdämmprofils invention for concealed receiving a cable, a sensor or other additional function in a window. It is also suitable as an air-conducting element in a forced ventilation window.

Insofar as the term window is used in this description and in the claims, this also means a door. The Use of the term window is so far only for easier understanding.
