Secondary Glazing

If you are lucky enough to own a listed building, or live in a conservation area, secondary glazing is your only option if looking to improve the insulation of your windows or maybe reduce the noise from passing traffic.

Secondary glazing can be single or double glazed and the system is an easy installation into your existing window frames or your window reveal. Sitting neatly behind your existing frames it is the obvious answer of how to improve window performance without altering the look of the exterior of your building. Hazlemere will supply and install made to measure secondary glazing in your home in any RAL colour of your choice. Our secondary glazing frames are lightweight aluminium, durable and easy to take care of.

Secondary Glazing for a happier home.

Adding an additional slim line window, even if double glazing is already in place, will improve thermal efficiency and choice of specialist glass can help deliver a reduction in noise.
