Secondary Glazing

Secondary Glazing is Discreet, Durable and Functional. A stylish and cost effective way of increasing both acoustic and thermal performance.

Homeowners install secondary glazing to combat 2 main issues, acoustic and thermal performance. The installation of secondary glazing boasts a great number of benefits and can be installed within all house types even Grade I and Grade II listed buildings. Our customers receive an 80% reduction in noise breaching the primary window and up to 65% reduction in heat loss.

Secondary glazing is often used in conjunction with single, double, and triple glazed uPVC or timber windows.

Made from durable aluminium and available in over 200 RAL colours our systems are discreet, functional and come with a 5 year warranty on frames and glazing and a 2 year warranty on moving parts.

The installation of secondary glazing within conservation areas is advised by Historic England as the installation does not change the original fabric of the building.

For more information regarding secondary glazing’s use within conservation areas or Grade I and Grade II listed properties please speak with us directly.
