Secondary Glazing Properties

Improving the thermal and acoustic performance of your listed property shouldn't negatively impact the character of your home. Our entire range of bespoke secondary glazing products come equipped with durable, slimline aluminium frames that accentuate the stylings of the existing window.

Installing secondary glazing is the most effective method of keeping external noise out and keeping the heat in. Our ultra-high- performance frames can educe external noise levels by up to 80% and reduce heat loss by up to 65%. All this whilst retaining your properties authentic aesthetics.

Why Secondary Glazing?

Our bespoke secondary glazing range is an ideal solution for listed properties and homes within conservation areas. Where replacement windows are not a viable option, secondary glazing provides all the thermal and acoustic benefits you'd expect from a 21st century window system, without damaging the unique aesthetics of the primary window.

From a sound insulation perspective, secondary glazing offers the most effective levels of noise reduction on today's market, significantly outperforming all other glass solutions. Our bespoke secondary glazing is manufactured using state-of-the-art machinery to lock-in a tightly sealed frame which can reduce noise levels by up to a whopping 80%.

If security is your priority, secondary glazing offers a unique, additional deterrent to any would-be intruders. Unlike traditional windows, secondary glazing is incredibly difficult to open from the outside and creates a further layer of defence against forced entry. Our frames are made from only the most durable, high quality aluminum and are securely fixed to resist forcing.

If draughty windows are of bigger concern for your property, secondary glazing adds an extra layer of defence to guard your home against heat loss. The small gap between your existing window and the secondary unit effectively acts as an insulator, creating a separate layer of air between the two which can reduce heat loss by up to 65%.
