Secondary Glazing
when quality meets your requirements
Secondary glazing gives you more than double the sound protection you would receive from a standard double glazing product. It also offers increased thermal insulation when compared to it’s more traditional counterparts. For heritage properties, you get all the preservation advantages of double glazing without destroying the look, history or status of existing structures. All this is made to fit exactly to your bespoke specifications using precision machinery.
​
Styles to Suit every window
Our discreet, internal windows are installed into the window space using either face-fixed or reveal-fixed units. There is a 10-20cm air gap between our system and the existing window which drastically improves both thermal and acoustic performance.
Units are made-to-measure from a vast selection of window styles and shapes. We supply horizontal sliders, vertical sliders, hinged units, fixed and lift-out windows.
​
Acoustic Glass Options
We can use special acoustic glass that reduces sound penetration by up to 54dB. Glass is made thicker than double-glazing with an air-cavity of between 15–20mm. Street-facing properties benefit where sleep quality is normally affected. Commercial property owners can also meet building standards on acoustic thresholds.
​
Energy Efficient
We use a low-E glass system has a reflective coating which diverts heat back into a room. Made with an 8mm air-filled cavity, the special glazing has added heat-retention, will reduce your home’s energy consumption and allow you to save a great deal on heating your home.

Find the perfect colour for your Secondary Glazed Window insulation system using our range of over 200 RAL colours that can match all modern colours.
