Why Install Glass Shutters

A report on the Development and thermal evaluation of a secondary glazing system by the University of Ulster, Centre for Sustainable Technologies, found a 40% improvement in the thermal performance of a single glazed sash window when Glass Shutters were used.


Glass Shutters provide:

  • added comfort from reduced heat loss;
  • an elegant design which compliments your period features;
  • the benefits of secondary glazing while still allowing easy access to your windows.

Roller blinds can be accommodated behind the Glass Shutters and existing wooden shutters can still be used.  We can provide detachable knobs with concealed ring pulls for these if required. In some areas, planning consent may be required and we advise customers to seek advice from their local Planning Authority.
