Yes he has the ear protection … but who needs hand protection?
Cavity Wall insulation – don’t do it!
Images from a thermal camera showing damp ingress on the internal leaf of the gable end of a Warehouse in Hampshire. Water has penetrated the outer brickwork and the “cavity” insulation has bridged the gap between the inner and outer leaves. The result – a very damp inner wall. The thermal imaging camera shows where it is damp (coloured blue/purple/black). Not very desirable!
