The bay window is the old type which has just wood underneath and a few brackets holding it up, the windows are double glased upvc though. Thinking of changing the windows in the summer, but for now is there anything simple-ish that can be done to improve the insulation? In the current weather the window sill on the inside is typically at 8 - 9 degrees C whilst the others in the house are at about 16 - 17c (thermostat is set to 20c).
The local DIY store is recommending a can of spray on foam for the outside but can't say how much this will improve things.
