As well as all of the other energy efficiency aspects mentioned earlier we are now embarking on quite a bit of secondary glazing in all of the mansions in Wales. Following successful trials at Chirk and Powis castle we are now targeting what we call the comfort heating zones in all of the mansions. These are places which are heated more than the museum part of the mansions areas such as tea rooms, offices and flats. This should have a significant effect on the heat losses esp from uncontrolled ventilation (get the original window to close properly first and don’t forget the heavy curtains). the system we have chosen is designed for each window and not a simple square profile which is then made up to fit. The profiles of the glazing bars are thin and powder coated to match the stone. On less sensitive area we have simply asked local joiners to make up frames for the windows.
If we can then there are no excuses. although the paybacks are longer we find it provided much better working environments. Because of the psychological effects on the people who control the heating ts much easier pulling the thermostat down that extra degree which can make a big difference
