A two bedroom house in a village in summer. Blue sky, yellow grass and the cracks are starting to appear.
The loft. No insulation. Baking hot in the summer, draughty and cold in the winter.
The bedrooms are 'rooms in the roof'. The top of the bedrooms have a layer of insulation but since the walls are lath and plaster afixed to the underneath of the rafters, it's not possible to insulate the walls without taking them down. The snow line shows where the heat is leaking out.
One year and 100mm of PIR insulation later. The snow hasn't lain on the left hand side because that side isn't finished.
