This need is driven by various factors that are characteristic of the contemporary construction sector and the growing do-it-yourself market. Firstly, there is an increasing demand for sealing systems that are both by professional craftsmen as easily and correctly as by do-it-yourselfers installed. The complexity of many existing systems often constitutes a barrier for effective application, leading to suboptimal results and potential water damage in the long run term. Secondly, construction projects are characterized by a wide variety of angle shapes. and dimensions. Existing sealing systems often lack the necessary flexibility to adapt to adapt to this diversity without making compromises in the area of waterproofing or aesthetics. This results in situations where custom work is required, which both time can be cost-intensive. In addition, there is a growing need for sealing solutions that require no prior have certain limitations in terms of shape or dimensions. The rigidity of many current systems limits their applicability in non-standard situations. Moreover, many systems offer insufficient flexibility to be effectively applied to the various angle shapes and kim angles that occur in practice. This can lead to improvisation and potential unreliable seals. Existing corner sealing systems are often pre-formed for fixed angles, making them not universally applicable for deviating angle variations. This often results in suboptimal seals that can fail over time. Moreover, many current systems lack the required accuracy in the sealing, especially with complex angle geometries. This leads to an increased risk of leaks. and reduced durability of the seal over time. In summary, there is a clear market need for an innovative corner sealing system that combines the following features: - Easy installation for both professionals and DIYers - Universal applicability to various sealing materials for building envelopes; - Flexibility to adapt to various angle shapes and dimensions - No inherent limitations in shape or dimensions - Installation without the need for special tools or on-site adjustments - High accuracy in sealing, especially with complex geometries Developing a system that meets all these criteria would be a significant signify progress in the construction sectors offer a solution for the long term challenges associated with effectively sealing angular building structures. The external angular construction, as occurs in various building structures can be defined by the following characteristic elements: 1. Vertex: The vertex forms the central element of the external angular structure. It is defined as the point where two or more surfaces of the building structure meet and form an angle ß. In practice, ß usually lies between 45° and 135° °, and in many cases amounts to approximately 90°, . 2. Flanks: The flanks are the side faces that define the angle at the edge and extend from the vertex. In a typical exterior angle, there are two flanks. These flanks can vary in length, material, and surface texture, depending on the specific building structure. The transition between the flanks and the vertex forms a critical zone for waterproofing. 3. Kimhoek: The ledge angle, also known as the ledge, marks the junction between a flank of the edge and an adjacent horizontal plane (such as a roof). The ridge angle is characterized by a specific angle Cl, where 25° < Cl < 90°. 4. Flat surface: This surface extends from the horizon and forms the horizontal or almost horizontal part of the structure where water can collect. The effective Sealing the transition between this flat surface and the flanks is crucial for the overall watertightness of the structure. The main purpose of the present invention is to address the problems mentioned above. to address by providing an improved corner sealing system. To this end, it comprises corner sealing system according to the inventions assembly of a first flexible corner sealing element, designed for partial installation on a flat surface surface of the building envelope, the corner point, partial placement against the flanks and the kimhoeken; a second flexible corner sealing element, designed for placement over an external one angled construction fitted first flexible corner sealing element and over the edge, in which the first and second corner sealing elements are substantially flat in the unused state; the first and second corner sealing elements are manufactured from a single piece of material which material is weather-resistant and / or UV-resistant; both the first corner sealing element and the second corner sealing element includes the mounting side, which is covered by a protective removable film, which can be applied to a surface welded, glued or adhesive on the mounting side according to the manufacturer's instructions; in which the first corner sealing element is divided into at least three sections: a first section intended for placement on the flat surface comprising an angle-following second section provided with a curved section for placement in the bilge angles of the two flanks; a third section intended for placement against the first flank; and a fourth section intended for placement against the second flank, in which the third section and the third section are by means of the angle-following second section connected to the first section. The described corner sealing system offers a number of significant advantages over compared to conventional sealing methods: By application of the first corner sealing element in which the third and fourth section in the corner following the second section is connected to the first section is it corner sealing system suitable for various types of external corners on a building envelope, such as roofs and facades, with a wide range of junction angles (25° < Cl < 90°). When applying of the first corner sealing element, the first section is into the corner without any difficulty. to construct the structure, whereby the third and fourth sections follow the bilge angle.
