Window expansion tape 30 mm / 7-15 mm, length 6,00m
It often happens that windows are fitted without the use of window strips. If you have forgotten to stick them on as well, nothing is lost and we have a solution for you to fix it. You solve it by sticking on expansion strips. These are glued to the window frame just before the polystyrene lining is insulated. The tape expands and fills the space between the polystyrene and the window frame. This ensures that rainwater does not enter the lining and, in the event of condensation, water vapour is released to the exterior. This is a very simple and fully functional solution.
