Secondary Glazing

Horizontal sliding secondary glazing

Subtle Style, dramatic difference

Andy Glass Windows are able to supply and install secondary glazing in a wide range of styles, individually designed to enhance your existing windows (not interfere with them.)

Secondary glazing is subtle and versatile.  Designed to shadow or surround your existing window configuration, the panels and layouts are measured to compliment your existing transoms and mullions. Meaning that the secondary glazing isn't visibly noticeable from the outside (and is often difficult to see from the inside!)

Recommended by both English Heritage and The Listed Property Owners Club, the benefits are outstanding.

Approved in conservation areas

Secondary Glazing from Andy Glass is ideal for any period building with original windows. Your building may be listed or located within a conservation area; or you might simply not want to replace your windows.  Whatever the reason there are many thousands of properties within the UK alone, where replacing original windows would be either forbidden or perhaps a little inappropriate.

  • Secondary glazing, when coupled with effective period window renovation, allows you to preserve the charm of your original windows - whilst helping you reap modern benefits.

  • Subtle and versatile, secondary glazing can compliment a renovation project with ultra-slim sight-lines - without compromising the operation of the original windows.

  • The aluminium sections used in secondary glazing can be powder coated in any RAL colour to match your existing theme.  From light oak wood grain effects to Chartwell Green or indeed any heritage shade desired - anything is possible.

  • Respectful appreciation of period styles mean that arches, rakes and almost anything bespoke can be fabricated by expert technicians.
