Profile strip

Abstract

Profile strip for creating a transition between two adjacent surfaces of a building, in particular an existing upper plaster layer and a component, in particular a frame part, wherein the profile strip has a thermally insulating structure and is attached to the frame with an elastic sealing tape.

Description

[0001] The invention relates to a profile strip for sealing, covering, and insulating an expansion joint between a component, in particular a frame part, for example a window, and an adjacent surface of a building, in particular an existing plaster layer during window replacement. It must also be considered that new, more tightly sealed windows may expose other weak points, where moisture may form. 2 State of the art

[0002] When sealing and insulating after installation, the transition from plaster surfaces to other components such as windows and doors represents a critical point. Firstly, the joint movements caused by temperature, wind, and driving rain loads on the elements must be accommodated. At the same time, any damage must be covered and the thermal insulation of the joints increased. These requirements can currently only be met through several work steps. Sealing arrangements, profiles, or strips are known to accommodate these movements. In the case of existing plaster layers during window replacement, these often lead to a reduction in thermal insulation in the window joint rather than an increase, thereby further increasing the existing risk of mold. Therefore, additional external insulation of the reveal must be installed at considerable expense. 3 Problem

[0003] The sealing system, known under EP application 24162855.1, features a particularly thin sealing tape, allowing for optimal thermal insulation in the joint and can accommodate the increased expansion caused by climate change. However, the thermal insulation properties of the masonry are insufficient to meet the requirements for mold prevention in the window reveal. Therefore, additional thermal insulation is currently being installed on the reveal, which is a time-consuming and costly process. This increases the temperature level of the masonry on the interior side and conceals damage to the surface of the exterior plaster. 4 Solution

[0004] The invention relates to profile strips that are equipped with a particularly elastic sealing strip, only 3 to 4 mm thick, and simultaneously feature a higher construction with additional thermal insulation. This ensures the necessary sealing, insulates the connecting joint as required, and covers any damage caused by window replacement in a single step. 6 Description of an exampleExemplary embodiment based on Figures 1 and 2

[0005] The profile strip (2) is glued to the window frame (1) and blocks the joint to the plaster (4).

[0006] The strip is glued to the masonry through a groove (3) for additional fixation so that it holds securely even with large dimensions.

[0007] The permanently elastic sealing tape (5) is equipped with a slowed return to reduce the return forces on the plaster (4).

[0008] The hollow chambers (7) increase the thermal insulation and reveal depth so that the minimum temperatures on the room side of the joint and on the masonry are maintained. QUOTES CONTAINED IN THE DESCRIPTION
