What is roof void insulation?
We start with access and safety: a walkway, lighting and the risk assessment for working in a large void, plus any asbestos register for the building. Insulation is laid on the ceiling or between ceiling joists, with services, light fittings and fire compartment lines kept clear. More about roof void insulation for a commercial building.
