Secondary Glazing is a slim-line window added to your existing windows. It is a fully functional and independent secondary window that is fitted on the inside of a property.

     As the Energy Saving Trust states, it is an ‘ideal solution if you are unable to replace your existing windows with double glazing’. It is a cost effective and efficient way of insulating & sound proofing your windows.   

     Perfect for use in conservation areas and listed buildings. It can be very slim and discreet, as it's made from strong light weight aluminium.

     Secondary glazing comes in different designs allowing us to match the existing window designs and easy access to the existing window for opening and cleaning:

  • Vertical sliding
  • Horizontal Sliding
  • Lift Out
  • Hinged (Butt or friction)



  • Increases thermal and acoustic properties of existing windows
  • Excellent noise reduction and sound proofing
  • Slim sightlines
  • Wide range of glass options with Self Cleaning Glass and Noise Reduction
  • Easy to clean and maintain
  • NO alteration to existing windows required - ideal for old and listed properties
  • Standard white colour
