Secondary glazing can reduce the heat lost through glazing by over 50%, and is much cheaper (though less efficient) than replacement sealed double (or even triple) glazing units. The lower costs means payment times for the investment are shorter.
What did we do at the Centre?
In this Small Meeting Room you can see magnetic made-to-measure secondary glazing panels. Having magnetic panels allows them to be removed in the summer. These were installed during a Volunteer Insulation event, drawing upon the £2,000 we gained in our work with Brighton & Hove 10:10 in a successful energy-reducing LEAF bid to government.
Elsewhere in the building you will seen custom-made fixed glass and plastic glazing held on with wooden beading, some of which was installed many years. Some were recently installed using materials purchased from the £10,000 prize win in the EDF Sustainability competition in October 2012.
