Secondary Glazing

Secondary Glazing

Secondary glazing is an effective way of improving your home’s thermal and acoustic insulation, especially if it is Listed or based in conservation area and the original windows have to be retained. Selectaglaze secondary glazing is a fully independent internal window, fitted on the room side of the existing primary window. It keeps the warmth in, draughts out, dramatically reduces sound levels, retains the character of the original windows and as a reversible alteration, is acceptable to both Heritage bodies and Conservation Officers. 

Warmer

Selectaglaze secondary glazing systems incorporate efficient seals to almost eliminate draughts and when glazed with low emissivity glass will reduce heat loss by up to 65%. This should show a notable reduction in energy bills and improve comfort levels in the home.  

Quieter

Bespoke and well fitted secondary glazing offers effective noise insulation. The secondary window frame is generally fitted 100-150mm away from the primary window, with the cavity working to limit noise transmission across the panes. Systems fitted in this way are capable of reducing noise levels by 42-45dB and even higher levels if a heavier glass is chosen, silencing the noise of passing traffic and or noisy neighbours. 

Safer

Windows are normally seen as "soft targets" for intruders and a secondary window, especially when fitted with a simple lock and strengthened glass, provides an additional barrier to entry. Our supplier Selectaglaze also offers enhanced systems accredited to Secured by Design (SBD) and are a Police Preferred Specification.  

Options

There are a number of styles of secondary glazing to help create a discreet treatment. They include; vertical sliding to match traditional box sash windows, horizontal sliding units, hinged casements as well as units that can be shaped to follow curves and arches of existing windows. Units can be colour matched or have a wood grain effect applied, making them even more unnoticeable.
