Description

Frame for a window or a door

The present invention relates to a frame for a window or a door, consisting of a frame and / or a sash constructed of plastic profiles, preferably of PVC, with at least a first inner chamber, in which a first infrared radiation barrier substantially parallel to the plane of the window or The door is arranged.

In particular, the invention also relates to a profile system and a method for producing windows, preferably of plastic windows, with increased thermal insulation.

Plastic windows have u .A. the advantage of good thermal insulation, which is achieved in that the profiles used are formed as hollow chamber profiles. As the number of so-called inner chambers increases, the capacity of thermal insulation increases. The state of the art today corresponds to window systems with 3 to 10 chambers. The disadvantage here is that the profile systems with increasing number of inner chambers have a greater depth and a higher weight and thereby cause higher production costs. The higher production costs result from a higher material usage with decreasing production speed. So z. B. Systems with 8 chambers to approx. 50% higher weight and a depth of about 75 mm, while for a three-chamber system usually a depth of only 50 mm is sufficient.

The insulating effect of plastic window systems is based on the insulating capacity of air and the relatively low thermal conductivity of the plastic. Plastic windows exist and the like. a frame and a sash made of mitred profiles made by welding in the corners. This creates encapsulated chambers in which the air is trapped. The higher insulating capacity of multi-chamber systems, however, is modest in relation to the overhead in production, due to physical constraints. The heat transfer from one chamber to the next takes place via the heat conduction in the PVC (PVC = 0.15 W / m K) and via the convection and heat conduction of the trapped air (air = 0.026 W / mK) as well as heat radiation. Thus, not the additional number of inner chambers ostensibly for the improved thermal insulation but only the additional depth (clear width of the profile chambers) prevail. Another measure to increase thermal insulation was made by introducing insulating foams (eg PU hard foam, λΡΙΙ = 0.035 W / mK), but with modest success, since such systems cause higher production costs, can be recycled only to a limited extent and large depths require. In summary, the disadvantages of multi-chamber system in a modest thermal insulation at the same time great depth and higher production costs.

By means of vacuum technology, a further increase in thermal insulation is possible. Individual closed to the outside chambers are evacuated after welding the mitred wing or frame profile bars. The heat transfer is reduced by heat conduction and by convection in air. The proportion of heat transfer by thermal radiation remains unaffected.

From DE 201 04 213 A or DE 44 26 331 A profile elements for windows are known in which the thermal insulation is improved by radiation barriers, which are inserted or inserted in individual cavities. As a result, a certain improvement is achieved, which is not yet completely satisfactory.

The object of the invention is to eliminate the above disadvantages and to provide a solution which has a still further improved thermal insulation.

According to the invention it is provided that in at least one further inner chamber, a further infrared radiation barrier is arranged substantially perpendicular to the plane of the window or the door.

Essential to the invention is the fact that not only the heat flow is inhibited perpendicular to the plane of the window or door effectively, but also the heat flow, which can sometimes pass through the frame perpendicular thereto.

In particular, it can be provided in the casement that the further inner chamber is arranged with the further infrared radiation barrier in Glasfalzbereich of the glass, or be provided in the frame, that the further inner chamber is arranged with the further infrared radiation barrier in the region of the wing frame facing surface. As a result, heat losses over the glazing rebate or over the gap between the frames can be effectively prevented. In order to additionally reduce the proportion of heat transfer by heat radiation, it is proposed according to the invention to use infrared heat radiation barriers preferably in the chambers of the profile facing the interior of the room. For this purpose, thin-walled, one-sided, reflection-coated infrared barriers are introduced into these chambers, care being taken to ensure the least possible direct contact with the profile material in order to avoid heat transfer by heat conduction.

By the solution according to the invention, it is possible to equip the profiles easier and with a smaller number of chambers and still achieve a better insulation effect. The main effect of the invention is not primarily based on the fact that an inner chamber is divided by the infrared radiation barrier into two sub-chambers, but on the fact that the heat transfer is effectively prevented by radiation. The infrared radiation barriers can be provided both in the sash profile and in the frame profile.

Preferably, the infrared radiation barriers are frictionally received in an inner chamber of the respective profile. This means that the profile forming the infrared radiation barrier is slightly deformed and resiliently supported on the inner wall of the chamber.

The thermal insulation at particularly critical points of the frame can be improved in particular by providing a flashover of the frame with an infrared radiation barrier and / or a flashover of the casement with an infrared radiation barrier to increase the thermal insulation. As a rollover part of the profile is referred to, which protrudes to form a stop for the insulating glass or the frame. It can also be included in the frame insulating glass Glasfalzbereich be provided with an infrared radiation barrier, whereby the thermal insulation is further improved.

Furthermore, the invention also relates to a method for producing a frame made above. Essential to the method is that the infrared radiation barriers are introduced before welding in the mitered profile sections. To facilitate insertion, the infrared radiation barriers are preferably deformed during insertion. This ensures a positive fit in the chamber.

The invention will now be explained in more detail with reference to Figures 1 to 4. Show it :

FIG. 2 shows a detail of FIG. 1 in an isometric view; FIG. and Fig. 3 and Fig. 4 two further embodiments of the invention in section.

Fig. 1 shows a plastic window, represented as a detail of a corner in an isometric view, consisting of a frame 1, a casement 2 and the insulating glass 3.

Fig. FIG. 2 shows a detailed representation of a plastic window according to the invention from FIG. 1 in an isometric view, consisting of the frame 1, the sash 2 and the insulating glass. 3

3a is the plane of the window which is parallel to the glass sheets of the insulating glass 3. In the frame 1, a first chamber 7 is arranged in the use position on the inside of the room. In this first chamber 7, a first infrared radiation barrier 7 'in the form of a thin-walled metal profile is inserted, which is slightly curved due to an oversize and is held in the first chamber 7 in a force-fit manner. Alternatively, a thin-walled plastic profile can be used, which is metal-coated on one side.

In addition, a further chamber 5 is arranged in the frame 1, which adjoins the gap 11, which is formed between the frame 1 and the casement 2. In this further chamber 5, a further infrared radiation barrier 5 'is arranged in an analogous manner. This is apart from the curvature substantially perpendicular to the first infrared radiation barrier 7 '.

In the casement 2, similar to the frame 1, a first infrared radiation barrier 6 'is arranged in a first chamber 6 and a further infrared radiation barrier 4' is arranged in a further chamber 4. The further infrared radiation barrier 4 'is intended to reduce the heat flow via the glass folding region 10. For clarification, the further infrared radiation barrier 4 'next to the window is shown again.

Reinforcing profiles 8, 9 are inserted in known per se in matching chambers of the blend frame 1 and the sash 2. These reinforcing profiles 8, 9 can according to the invention as well as the other infrared radiation barriers 4 ', 5', 6 'and 7' be glossy coated or mirrored, in particular also on the surfaces directed to the other chambers 4 and 5.

Fig. 3 shows the plastic window according to the invention in cross-section, consisting of the frame 1, the casement 2, the insulating glass 3, the infrared radiation barriers 4 ', 5', 6 'and 7', wherein the reinforcing profiles are omitted.

Fig. 4 shows a variant of the plastic window according to the invention in cross-section, in which an additional further infrared radiation barrier 12 'is provided in the frame 12 on the inside of the rollover 18 and in the sash profile 2 an additional further infrared radiation barrier 15' on the inside of the rollover 16. These infrared radiation barriers 12 ', 15' can already be produced in the course of the extrusion or else be applied to the profile sections afterwards.

On the insulating glass 3, a further infrared radiation barrier 17 'is likewise provided in the glass folding region 10, which is pulled up beyond the end face onto the glass surfaces in order to avoid thermal bridges.

In additional chambers 13 and 14, additional infrared radiation barriers 13 'and 14' are additionally extruded. The infrared radiation barriers 12 ', 13', 14 'are disposed on inner webs 22, 23, 24 which are preferably extruded and more preferably fiber reinforced material.

The present invention makes it possible to optimize the thermal properties of windows or doors.
