Original upvc window seals can become compressed or perished therefore may need replacement. Window seals act as both draught proofing saving on your heating bills but they also act as soundproofing. This should not affect the performance of your window/door in most circumstances this product will provide a new airtight/soundproof seal. Replacement may be needed where your existing rubber window/ door seals have become compressed and are not fully sealing the gap in the window when it is closed, this will then let in both air and external sound.
