Secondary double glazing

Granada Secondary Glazing

Joinery and Heritage Craftsmen are official agents for Granada Secondary Glazing, a UK manufacturer of high quality internal glazing units with over 35 years of experience. Secondary glazing units are a sensible alternative when there is insufficient depth in window frames to install heritage double glazing units, and the only alternative would be to re rout the sashes - or expensively manufacture new ones. If you can't install heritage double glazing panels or are not allowed to do so, secondary glazing is a sensible and cost effective alternative solution. Granada's aluminium framed units sit inside the window recess and provide more efficient soundproofing and draughtproofing than when using heritage double glazing, reducing heat loss by up to 77% and up to 80% noise reduction when compared to a standard window. An 80mm gap between the existing window and the secondary unit effectively acts as an insulator, creating a separate air layer which keeps cold air outside. Granada produce a wide variety of frames in various opening configurations and in over 200 powder coated RAL colours, a brief selection of which is illustrated below. If you're considering a window draughtproofing solution, we'll be delighted to advise you.
