The up to wall clip serves an essential function by creating expansion between the elevated terrace and the surrounding boundaries. The elevated terrace, which is a type of floating floor, is not permanently connected to the building's structural elements, neither from below nor from the sides.
Separating the terrace from the surrounding boundaries, which are usually walls, parapets, railings, window frames, etc., aims to create a ventilation gap between the elements. The lack of proper separation and permanent connection between the two elements leads to the formation of damp areas, which over time can result in mechanical damage and potential leaks. Moisture-exposed contact areas are particularly prone to biological corrosion, significantly impacting the aesthetics of these areas.
The elevated terrace, as a floating floor, is subject to thermal expansion, causing variations in the dimensions of the terrace surface. Therefore, it is necessary to ensure proper expansion between the individual elements. Failure to apply appropriate expansion can lead to stress and damage to the terrace, cracking of the tiles, and deformation of the surrounding boundaries.
The up to wall clip creates a gap with a width of approximately 8 mm, which provides the appropriate distance and prevents the formation of damp contact areas and damage related to thermal expansion. In the case of materials characterized by higher thermal expansion, it may be necessary to increase the width of this gap.
In the case of terraces with a significant surface area, where there is an uninterrupted terrace surface exceeding a length of 10 m, it is necessary to calculate the allowable dimensions of terrace expansion based on parameters provided by the manufacturer of the terrace flooring, such as tiles or decking boards.
