• Barely noticeable.

  • Stay warm in the winter and cool in the summer.

  • Vertical soundproofing.

Secondary Glazing

Secondary glazing is ideal for buildings of every period where, windows require regular ventilation. Casement windows but can be used for many other styles that make secondary glazing an ideal economic solution to reducing noise and heating bills.

Vertical secondary glazing can be mounted within the ‘staff beads’ of a vertical sliding sash window, allowing the lower panel to be opened and enabling the retention of working internal shutters. This is an important priority when satisfying the needs of Conservation Officers.

Horizontal slider systems and vertical systems are:

  • Easy cleaning with windows simply lift out for easy cleaning and storage – it could not be simpler. Suitable for Georgian, Victorian and Edwardian vertical sash windows.
  • Substantial energy savings are achieved and overall efficiency can be doubled by improving the heat-loss coefficients.
  • Noise reduction that is typically more than twice as effective as double glazing. With an air-gap of only 40mm and using 4mm toughened glass noise was reduced by 40dBA while retaining normal working of existing internal shutter.
  • Ultra-thin lightweight framework means that its visibility is kept to an absolute minimum.

Listed Building Consent is required for any alterations that would affect the character of the building and it is a criminal offence to carry out these works without consent.  If you wish to carry out any work on a Listed building you will require Listed Building Consent through your local authority. If the building is in a conservation area then advice should be obtained from a Conservation Officer at your local planning authority.In any instance Wells Glass can take you through the process as painlessly as possible.
