My loft insulation is saving me cash

We had snow during the night, not a lot just a slight sprinkling, I had a look at my roof today and it was all white, the snow had not started to thaw.

The snow on my neighbours roof next door had all melted and so had most of the other roofs in the street.

You may recall last summer I insulated the loft to a depth of 12 inches with Rockwool, .. now it's paying off.
