Aluminium Secondary Glazing
We supply and install a range of secondary glazing styles throughout Derry City, The North West and right across Northern Ireland.
Secondary glazing is a fully independent internal window, fitted on the room side of the existing primary window. We fit a range of secondary glazing, designed to provide effective noise insulation, thermal and draught insulation and enhanced security. When glazed with low emissivity glass they can reduce heat loss by up to 65%. The comprehensive range of secondary glazing allows sympathetic treatment of almost any style of window.
All units are bespoke and designed with careful consideration to meet the needs of the project.
Secondary glazing has stood the test of time and still proves to be one of the best forms of protection for homes, public and private sector buildings and industrial units against heat loss, draught and noise intrusion. APG provide a comprehensive range of secondary glazing options to our customers.
Secondary glazing is a perfect solution for a conservation area, and listed properties where altering or replacing the prime window is not possible or cost-effective. It can even benefit those windows that are already double glazed particularly on noisy main road areas where noise is an issue.
Practical Benefits with Security in Mind
Feeling safe in your home is an essential factor when choosing to upgrade your windows. Secondary glazing, however, doesn’t involve replacing your existing frame but includes adding a second layer of protection. Using modern technologies, our glazing offers superior security for your home.
Unlike singled glazing, our secondary windows are exceptionally difficult to break into from the outside. Provide your home with an additional protective barrier from unwanted intruders and guarantee your home an inherently strong and robust entry. Giving you the peace of mind that your home will remain secure.
Modern Properties
Secondary Glazing is not only for homes in listed and conservation areas; it also works well in more modern properties. Many customers opt for Secondary Glazing due to the level of road traffic noise, flight paths or a nearby railway.
With Acoustic Noise Reducing Glass you can leave the commotion outside where it belongs.
