Whether you’re fitting new frames or carrying out maintenance and repairs, our silicone sealant for windows provides reliable adhesion, flexibility and protection against the elements for both domestic and commercial applications.

Window Silicone Sealants for Durable, Weatherproof Window Sealing

Proper sealing around window frames is essential to prevent water ingress, draughts and heat loss, which is why Bond It develops high-performance silicone for windows and window sealant solutions trusted by trade professionals across the UK. Our formulations are engineered to bond securely to common frame materials including uPVC, aluminium, timber and coated surfaces, ensuring a clean, durable finish that performs in all weather conditions. Whether used internally or externally, each silicone window sealant is designed to accommodate movement caused by thermal expansion and building settlement without cracking or losing adhesion.
