secondary double glazingSecondary double glazing, for existing windows and doors.

Secondary Double Glazing is a method of soundproofing and insulating your home without having to replace your existing windows. Easily the most cost effective noise solution for the majority of situations, it’s fast, simple, and typically requires no changes to the existing window or window dressings.

Using the Winseal™ system, sliding glass or hinged panels are custom-made to fit to your existing window frame. The fit is exact and provides an insulating pocket between your existing window and the Winseal™ pane, creating an independent and isolated system working in harmony with your existing glass to soundproof against intrusive noise, and insulate your home.

Saving energy and helping the environment, Winseal™ will typically turn a one or two star rated window into a 6 star system overnight.
