Aluminium Secondary Glazing

Offering superior noise reduction, ideal for conservation and listed properties.

Strong, reliable, long lasting and unobtrusive

Perfect solutions for heritage and conservation

Often, the only way to retain the external character of a period property is to use secondary glazing. Our designers can ensure that slimline aluminium sections will sit discreetly behind your window frames, preserving the original look.
 
Our aluminium secondary glazing offers increased thermal insulation, enhanced sound insulation and improved security, as well as reducing condensation.
 
The most popular options are vertical and horizontal sliding, however, hinged, lift-out or fixed units, can provide an alternative solution.
