You wouldn’t leave a window wide open if the heating were on. But if you have stripped floorboards, the chances are that you’re doing the equivalent.
Cold air naturally circulates below ground floor floorboards, and the small gaps between boards in an average-sized room add up to the equivalent of a small window. No wonder your toes are feeling chilly. According to the us, just filling gaps between floor and skirting boards will save around £20 – and 100kg of CO2 – annually, paying for itself in less than a year.
