A timber-framed extension in St Andrews, with PIR boards cut between every stud and floor joist, joints taped and a foil vapour layer over the top, ready for plasterboard.
A timber-framed extension and renovation in St Andrews, next to the original blockwork of the house. The walls and floor needed insulating before any linings went on.
Quinn Therm PIR boards cut tight between every stud. A snug fit matters more than the board: a few millimetres of gap all the way round is a lot of heat over a whole wall.
Foil tape across all the board joints and edges to make the wall airtight.
A foil vapour control layer over the boards, so warm, moist air from the room can't get into the frame and condense.
Service battens over the top for cables and plasterboard, and the same PIR boards fitted between the floor joists.

Floor joists filled with PIR, walls battened ready for board.
