Maintains 270mm insulation & structural warranty
In modern and energy-efficient UK homes, mineral wool quilt insulation is laid 270mm to 400mm thick. Screwing boards straight onto 100mm joists crushes the quilt, causing severe heat loss, cold ceiling spots, and condensation damp.
Our certified fitters install specialized raised subframes — including the award-winning Loft-E® metal system for new builds and robust engineered timber frames for traditional Durham homes. We then lay premium 18mm P5 moisture-resistant tongue-and-groove boards.
