A full loft conversion in Perth: the sloping ceilings, flat ceiling, dwarf walls and stud walls all insulated before the plasterboard went up, on a new structural floor.
Turning a loft into a room means insulating the roof itself, not just the loft floor. Every surface of the new room needs doing, and each needs a different approach.
Xtratherm PIR boards fitted between the rafters on the sloping ceilings, leaving the ventilation gap above.
A foil vapour control layer across the underside, taped at the joins, to keep moisture out of the roof.
PIR boards in the dwarf walls and a reflective multifoil in the stud walls.
Mineral wool between the ceiling joists at the top of the room before the plasterboard went up.
Stud wall with the multifoil fitted between the studs.
Ceiling insulation going in as the plasterboard goes up.
Attic rooms are the hottest in summer and coldest in winter if the roof isn't done properly. Insulating every surface, with a proper vapour layer, is what makes a converted loft a room you can use all year.
