Description

State of the art

TECHNICAL FIELD:

Construction, thermal insulation of buildings in the facade area

When carrying out thermal insulation in new buildings, it is common to use insulation layers that are installed directly in the wall area or on the outside of load-bearing walls. The windows and insulation are then on one level. As proof of such solutions, the example from Soprema 'SOPREMA, WAND-TECHNIK, system solutions' 11/2022 on page 50 is mentioned.

The situation is different in the case of renovation measures that are necessary for energy efficiency purposes. In the case of additional insulation measures to reduce heat losses, an insulating layer is almost always applied to the outside of the load-bearing wall. Existing windows and the new insulation layer are then no longer on the same level. This offset leads to thermal bridges and thus to heat losses. In addition, other structural problems can arise. In colder zones in the area of the existing window frame, condensation can occur and thus mold can form. The existing windows must therefore be removed and reinstalled at the insulation level. In addition, the laterally open cross-sections of the insulation materials around the window or door cutouts must be protected and covered. For this purpose, so-called soffit panels are used, which then have to be plastered. The GUTEX implio P soffit panel ('GUTEX implio,

Another example of soffit cladding is the products from Fixotherm Fensterbank-Dichtsysteme GmbH (www.fixotherm.at, stand o4/2023). Here the cladding is handcrafted from insulating materials, which are then plastered.

Frame-like enclosures are only known for covering the wall and the perimeter insulation. However, the window is not on the same level as the external insulation. Example: MEA CONNECT SYSTEM, brochure 010264015/ DE/07.2021 , Perimeter cover frame MEAFRAME, www.mea-group.com/de/produkte/abdeckkasten-fuermealuxit/ from 6/2023.

A drip tray is usually attached to the lower horizontal surfaces of the window cutouts, the side legs of which are plastered or placed on plaster. Such a construction often causes damage due to surface water penetrating the plaster layer.

Lintel boxes to be installed in the upper window area are known and common. They are attached to the wall area and are suitable for holding roller shutters, slat packages or textile screens. They do not represent a system-compliant solution in the sense of possible prefabrication. The boxes are added additively. Example: JOMA blind boxes, not just for passive houses (at www. joma.de), as of 2023.

Prefabricated system solutions are usually not available. Handcrafted constructions using a variety of individual products such as sealants, foils and reinforcements are necessary to achieve a result in terms of sealing the openings.

Problems and problem solving

The invention relates to the design and arrangement of frame structures for window or door openings in building walls, which are provided with thermal insulation on the outside of a load-bearing wall in order to improve the thermal protection of the outer wall.

Correct coordination of the insulation level of windows with the insulation level of the external insulation is particularly important for renovation tasks. The levels must not be offset here in order to avoid thermal bridges and subsequent phenomena such as condensation and mold formation on the inside of the wall. In order to achieve this goal, the old window constructions must be renewed and moved to the level of the external insulation. The inner frame parts (1) are positioned in the reveal opening in such a way that a window sill (13) on the inside can be left without changing the arrangement. The invention combines the individual aspects of window or door arrangement, insulation level and their termination in the area of their cutouts as well as the integration of a pocket to hold roller blinds, blind drives and protective devices (8) into an overall solution.

An inner frame part (1) rests on the load-bearing wall (12). The inner frame part supports the offset window (10) and bridges the zone between the original window position (14) and the external insulation (11). An outer frame part (2) engages over the inner frame part (1) in such a way that a stepped overall frame (3) is formed. The outer frame part (2) closes the outer insulation (11) and the Facade cladding or plastered surfaces (17) opposite the window or door cutout. This closure enables the construction of composite insulation as well as curtain or rear-ventilated facade cladding and protects insulation materials or plaster from moisture. The depth of the outer frame part can be varied for different insulation thicknesses or facade constructions of different depths. The overall frame can also be designed in such a way that by extending the outer vertical frame profiles (4) (7) an overall frame (6) is created, which has a pocket (8) for accommodating drives and protective devices such as roller blinds, blinds or screens (9 ) forms. This also makes it possible to arrange the side guide rails (16) for roller shutters or blinds on the inside of the outer frame part. A drip tray (15) made of folded sheet metal can be mounted on the horizontal threshold of the outer frame part. The side edges of the drip tray engage behind the outer, vertical frame profiles (4) or the extended outer frame profile (7) due to a slot-like recess (5) so that rainwater can run off onto the drip tray. This also ensures structural wood protection at this point.

The overall construction enables prefabrication and combination of previously individual components. This also enables optimal planning and production of the windows to be installed.
