Mineral Wool (Loft Roll)
Mineral wool (glass or rock wool) loft roll is the UK's most widely used loft insulation material. It is laid between and over the ceiling joists of an unused loft to a recommended depth of 270mm, meeting current Building Regulations. Installation is quick, affordable, and highly effective at reducing heat loss. Government-backed grants may cover part or all of the cost for eligible homeowners.

Frequently Asked Questions
How thick should my loft insulation be?
Current Building Regulations recommend a minimum of 270mm of mineral wool insulation. If your existing insulation is less than 100mm, topping up to 270mm is one of the most cost-effective energy improvements you can make.
