Insulation

While I was living in the house before the builders started I rarely put on the heating because the house was so air-leaky. I just wore lots of layers, sometimes including a hot water bottle, and was a heat sink for my neighbours. The brick wall to the right of the picture is their external wall and next to it is how much insulation I am offering them. I hope that is some recompense for how much heat I pilfered last winter and the winter before.
