Window Sealing

To maintain quality and ensure your double glazed windows and double glazed doors perform consistently well in any weather, it is imperative that all gaps are closed. Depending on whether the installation was performed externally or internally, the best sealant will be selected. Just as there are many different types and grades of windows or hardware, there are many different grades of sealant quality. We only use high-performance products to ensure the window and door quality is not compromised. A sealant bead at the final stages of installation ensures the possibility of draughts is eliminated, preventing water penetration and damage while leaving the appearance neat and attractive.

Many people believe that all silicone gels on the market are the same, but we have found that their properties and suitability vary dramatically. Generally, silicone descriptions offer little information about the correct grade and type for a given application. Because of performance variability, no single type of silicone sealant should be used for everything. Using the incorrect silicone or improper application may cause joint failure, contamination of surfaces, or excessive movement in the sealed joint. To avoid contamination of surfaces, the installer should ensure that the surfaces are clean, all protective tape is removed, and there is no residue. For deep or wide joints, the installer can fill the recess with foam packer rod.
