1. Weather Resistance
Your new windows or doors will be completely draught-proof and watertight. The Slimline profile is produced with all weather bubble gaskets (seals), fused to both the inner and outer frame section.
The bubble gaskets are hollow and offer greater compression and remain in-line with the profile for a neater appearance. They are fused to the profile, which means they can never shrink back, reducing the chance of leaks or unpleasant draughts in your home.
