Secondary Glazing Benefits

Take advantage of the many benefits of Secondary Glazing

Installing secondary glazing with our standard glass will completely eliminate any draughts and cold spots that you currently have with your existing windows.

Secondary glazing frames are made from long-lasting aluminium with integral timber subframes which are sealed to the existing structure to ensure that the thermal integrity is maintained.

The clever design of our secondary double glazing ensures that they remain unobtrusive and blend in as much as possible with your existing window – they are even available in a wide range of colours to exactly match your internal decor.
