Aluminium Secondary Glazing

Secondary glazing involves adding an extra slim-line window in addition to your existing windows. It is an effective and cost efficient method of insulating and sound proofing your windows. If you’re worried about ever increasing energy costs, secondary glazing could save you 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.
