Compatibility of building materials
In many cases, the sealing of joints represents a link between different materials. These can be paints, treated wood constructions, various plasters or even residues of existing sealing products.
In order for the waterproofing product to fulfil its requirements in the long term, no harmful interactions must occur. These can be chemical, physical or optical impairments, which must generally be avoided. To ensure this, compatibility tests must be carried out.
As a rule, pre-compressed sealing tapes have the advantage here, as only a physical expansion takes place.
Depending on the installation position of the window, the materials listed below may impair the sealing products:
- the coating system of the façade or window
- impregnation systems of a timber construction
- old sealing materials
- Release agents from the production of window profiles
- Natural pest
