Horizontal Sliding Secondary Glazing

About Horizontal Sliding Secondary Glazing

Secondary glazing units offer the perfect piece of added insulation against the cold and extra protection from noise pollution. Here at Sussex Glazing, we fit these secondary glazing units to standard windows and doors at commercial and residential premises across East and West Sussex. If you are looking to enhance your home or workplace, then secondary glazing units may well be just what you are after.

Horizontal sliding units

We install a large range of secondary glazing units, including fixed, hinged, lift out, vertical and horizontal sliding units. The horizontal sliding units that we install allow the secondary glass panel to slide easily and smoothly from side to side.

It slides on brass rollers, which means that you have easy access to your main window or door. This is handy for cleaning, maintenance and for extra ventilation, when required.

A range to choose from

As with all of our products here at Sussex Glazing, we offer a huge range of choices, to ensure that you end up with the perfect product for your home. We understand that when it comes to your Sussex home, you will want to ensure that you are selecting windows that match your decor and all of your needs.

Therefore, we offer a large choice of sizes and fittings, as well as a huge range of finishes, colours, and styles.

Where can these be used?

  • On individual windows that are used for ventilation
  • Over the glazed panels in doors
  • Over any shaped window
  • Over stained glass windows, to offer extra protection and insulation
