Description

The invention relates to a wood-aluminium window or a wood-aluminium window door in wood-aluminium construction with glazing, a frame and a sash frame made of wood, with an aluminium profile forming an outer weather protection layer,

Such windows are known, for example, from DE-3844195-C2. From the wealth of other solutions, DE-29715346-U1, DE-29714268-U1, DE-19910320-A1, G-9214934.0, G-8332970.6, DE-3308384-A1, DE-19516486-C2, DE-3309541-A1, DE-4403087-C2, DE-4404565-C1, DE-29820220-U1 or EP-0169918-Bl should also be mentioned here.

A major problem with the known solutions is that they do not meet new regulations regarding thermal insulation, or are too complex to construct or too expensive to manufacture.

The object of the invention is to create a solution with which a wood-aluminum window or a wood-aluminum French window has good thermal insulation, is inexpensive to manufacture and the materials are reusable [recycled].

This object is achieved according to the invention in that double insulating glazing (6, 7) is provided as glazing (1) and a thermal insulation layer (8, 9) is attached to the outer sides of the cover and sash frame (2, 3), wherein the aluminum profiling (4, 5) covers the thermal insulation layer on the outside and the double insulating glazing is held by the thermal insulation layer (9), the aluminum profiling (5) and the sash frame (3), wherein the weight of the insulating glazing is essentially borne by the sash frame (3).

The invention achieves sufficient thermal insulation of about 1.2 W/(m ² k) for the entire window using comparatively simple means, so that the requirements for a low and ultra-low energy house [3-liter house] are met.

Advantageous embodiments of the invention emerge from the subclaims.

According to the second claim, an insulating glass with a thermal transmittance of 1.1 W/(m ² k) is expediently used.

According to the third claim, it is advantageous to use a rigid foam for the thermal insulation layer.

In a further embodiment of the invention, according to the 4th claim, the thermal insulation layer is approximately 23 mm thick.

Preferably, according to claim 5, the frame is constructed from three layers of wood.

For cost-effective production, standardized wooden window profiles [DIN 68121] are used for the frame parts in accordance with claim 6.

Advantageously according to claim 7, conventional seals are used, so that low costs arise.

According to claim 8, all materials are mechanically connected to one another, which enables reuse.

Advantageously, according to claim 9, a heat transfer coefficient of 1.1 W/(m ² k) is achieved for the frame parts.

Advantageously according to claim 10, a thermal transmittance coefficient of 1.2 W/(m ² k) is achieved for the entire window.

Further features, details and advantages of the invention will become apparent from the following drawing and description:

Fig. 1 shows a simplified section through an embodiment.

The use of standardized wooden window profiles for the sash and casement frames has the advantage that important properties, such as joint permeability and watertightness, are known and do not have to be determined again, which further reduces costs because standard window manufacturing tools can also be used.

The structure of the frame parts comprises three levels:

1. Weather protection layer outside, 2. Thermal insulation layer outside, 3. Stability, functional and optical layer inside.

The construction depth of the frame without aluminum profile is 88 mm.
