DL467 – Raised Loft Boarding System – Pitched Roof With Insulation at Ceiling Level

Price range: £9.00 through £14.00 + VAT

This detail illustrates a raised loft boarding system installed over a pitched roof with ceiling-level insulation. A high-performance mineral wool layer provides thermal insulation between ceiling joists, with a vapour control layer below and a ventilated 50mm air gap above. The raised boarding platform is installed to the manufacturer’s guidance, ensuring unobstructed airflow across the loft void. Rafter ventilators and over-fascia ventilation maintain consistent airflow and reduce the risk of condensation.

See drawing notes for full information.
