A very important detail is the treatment of the lining on the facade. Construction companies often want to save money and use the cheapest flashing profiles, which is often a very bad choice. They run the risk that the adhesive tape is of poor quality and that the grid may separate from the PVC profile. To illustrate this, the picture below shows the consequences this can have. The sight of such a cracked lining will not please even one householder.
The solution is to use quality locking profiles, preferably with a cover sleeve. We prefer profiles PROTECTOR no. .
