Styles of secondary glazing

Secondary glazing is a popular choice when it comes to the problem of how to improve the thermal efficiency and sound proofing of sash windows and casement windows in listed buildings and period properties, by installing secondary glazing you can keep the look of your period property intact with internal sightlines remaining the same and at the same time complying with planning guidelines for conservation areas and listed buildings.

There are many styles and configurations of secondary glazing to suit the layout of your original sliding sash windows, casement windows or more modern variations , below you will find a comprehensive range of styles and variants of our secondary glazing systems to suit your every need, if you need any more help please don’t hesitate to contact us.

Where can Secondary Glazing be used?

Secondary glazing systems really come in to there own when you have limitations on how you can improve the thermal efficiency of your windows and to reduce noise pollution. This is mainly if you own a listed building or live in a conservation area and conventional double glazing is not an option for your property due to planning restrictions and government guidelines, in some instances you can fit slim double glazing but this is hit and miss as it is up to the discretion of your local conservation officer, if slim double glazing is an option you would like to pursue check out our sister company Kensington sash window restoration.

So secondary glazing is the obvious choice in these circumstances as it drastically reduces heat loss, cuts down on noise and is easily fitted without any major disruption or mess, most average sized homes can be fully completed in 1-2 days.
