Thermal imaging surveys conducted by EWH last week have clearly revealed how effective shutters, curtains and blinds are at preventing heat loss through windows.
A thermal imaging camera reveals where heat is leaking from a building, with hot areas showing up red and colder surfaces in blue. Throughout the World Heritage Site the results were consistent, where shutters and curtains were closed they proved to be highly effective in keeping in the heat.
The photo opposite was taken of a typical Georgian New Town house. The windows with closed shutters on the first floor in blue, contrast dramatically with those on the ground floor.
