Draughts can be cured

“What is the one thing everyone should do?” is the question I get asked most often by newspapers, interviewers and the like. What they want are some pearls of wisdom on solar panels or heat pumps or some such. But the, perhaps disappointing, answer is draught proofing. In an older property dr…

The typical cavity is 50mm (2 inches) wide and 50mm of foam insulation will reduce the heat loss through the wall by around 75%. As 35 per cent of the total hea…
