Questions about room-in-roof insulation in Winchester

Can it be done without removing the plasterboard?

Sometimes the flat ceiling and eaves voids can be reached from behind. The slopes almost always need the boards off to insulate them properly.

Will the room get smaller?

Slightly. Insulated plasterboard over the rafters takes a few centimetres off each slope.
