Loft Insulation

Glass mineral wool loft roll for insulating between and over ceiling joists. Current Building Regulations guidance for lofts is around 270mm in total, usually laid as two layers. Prices ex VAT, delivered to England and Wales.

100mm loft insulation usually goes between the joists, with a 150mm or 200mm layer laid across them to reach around 270mm in total. Order enough rolls for both layers: each product page shows the m² per roll.
