Aluminium Secondary Glazing

We have one of the broadest ranges of bespoke Secondary Glazing in the UK. Secondary glazing involves adding an extra slim-line window in addition to your existing windows. It is a effective & cost efficient method of insulating / sound proofing your windows. If you’re worried about the ever increasing energy costs, then you could save around 10% on your heating bills. The Energy Saving Trust states that it is an ‘ideal solution if you are unable to fit double glazing’.

Secondary glazing is perfect for use in Listed Buildings and conservation areas. Made from strong light weight aluminium, it can be made to be very slim and discreet. Considered a reversible change, secondary glazing is recommended by English Heritage and the Listed Property Owners Club.
