Dear forum members,
We had our fairly large house insulated for about 50,000 with 18cm mineral wool (7 inches). A strip (telescopic mesh strip) was glued onto the connection elements, such as windows and doors. This strip is supposed to be able to compensate for slight expansions (up to 2.8mm).
However, in our case the strip has detached from almost all windows and doors, leaving a gap of about 2mm between the windows and the strip. You can slide a Japanese spatula or paper about 2-3cm (1 inch) behind it. Excessive expansion as a cause can be ruled out, since it is clear that the expansion range in the strip has not opened at all. For one door, the cause was that the strip was glued onto tape, but this was not the case for the windows. There, the strip was already glued several days before the insulation work started.
The company that carried out the insulation now wants to solve the problem by cutting the sealing tape, which the strip is glued onto (SK-PE sealing tape), at an angle to create a small gap and then filling this gap with silicone.
My question is: Is this an appropriate solution to the problem? The silicone joint is a maintenance joint that needs to be regularly checked and maintained. A properly functioning strip would be the better solution, which we have also paid for. How would you handle this situation?
Thank you for your opinions,
Arne
