Room-in-Roof Insulation

Improve comfort and energy performance in converted loft rooms, dormers, and roof spaces.

Room-in-Roof Insulation

Rooms built into the roof can lose heat quickly through sloping ceilings, dwarf walls, dormers, and hidden roof voids when insulation is incomplete or unsuitable.

Sublime reviews the room layout and heat-loss areas before recommending insulation measures that suit each part of the roof-room structure.
