FRAME CONSTRUCTION FOR A WINDOW, A DOOR OR A FIXED GLAZING

Claims

1. Frame structure for a window, a door or a fixed glazing, comprising: - a frame profile (2, 3), the material of which has a thermal conductivity of less than 1.0 W / mK and - a sash or leaf frame (2) as well as - a fixed frame (3); - a vacuum insulated glass unit (1) that is held at an insertion depth (S3) of the frame structure (1); wherein - the vacuum insulated glass unit (1) has a heat transfer coefficient Ug of at most 1.0 W / (m2K); characterized in that - the frame structure comprises a thermal coupling element (5; 15) on the interior side in the region of the insertion depth with a thermal conductivity that is increased with respect to the material of the frame profile of the sash or leaf frame (2) by a factor of at least 10 and preferably a thermal conductivity that is increased by a factor of 20 and particularly preferably a thermal conductivity that is increased by a factor of 300; and - an outer insulation thickness (S1) in the heat flow direction that is greater than the thickness (S2) of an inner seal (6) by a factor of at least 3, preferably by a factor of at least 4.

2. Frame structure according to claim 1, wherein the frame structure has an interior-side rebate which is provided in the form of a glazing bead (5) or a fixed rebate, wherein the interior-side rebate comprises the thermal coupling element (15).

3. Frame structure according to claim 1 or 2, wherein the frame profile of the sash or leaf frame (2) consists of wood, rigid integral foam, GRP, CRP or thermoplastic material, in particular PVC, PP or PA, or of a composite profile made of wood and rigid foam or of a composite profile made of thermoplastic material and rigid foam.

4. Frame structure according to any of the preceding claims, characterised in that the insertion depth (S3) of the vacuum insulated glass unit (1) is between 15 mm and 25 mm.

5. Frame structure according to any of the preceding claims, further comprising an insulating element (12) that is arranged on the exterior side in the region of the insertion depth of the vacuum insulated glass unit (1).

6. Frame structure according to any of the preceding claims, characterised in that the thermal coupling element (5) comprises metal at least in regions and is preferably a glazing bead (5) made of aluminium.

7. Frame structure according to any of claims 1 to 5, characterised in that the thermal coupling element (15) is aluminium foil, with which the glazing bead or rebate (5) is covered.

8. Frame structure according to any of the preceding claims, characterised in that the thickness of an outer seal (4) in the heat flow direction is at least 50% greater than the thickness of an inner seal (6).

9. Building envelope comprising a frame structure according to any of the preceding claims.
