Insulation is now being added to the inside of the roof. It is being cut and fitted between the rafters before being sealed at the edges to make it extra energy efficient.
The insulation is standard sheets of Celotex – the kind of thing that is used in typical brick construction between skins. This insulation stays in place on a slope in the way that the Earthwool wouldn’t.
The original plan was to run the insulation vertically down this stud wall, but now that this is becoming a cupboard, the insulation needs to carry on in the roof joists.
The guttering and roof tiles have now been removed – making this feel more like the inside of a building – and the triangular timber wall frame has been built.
