How many loft rolls do I need for my space?

Knauf Insulation Earthwool loft roll is available in 3 different thicknesses - 100mm, 170mm and 200mm. UK building regulations require 270mm of mineral wool insulation at ceiling level in a loft so the most common way of achieving this is through 100mm in between the joists and 170mm cross laid on top.

To achieve maximum performance, choose our 200mm loft roll, which will give a higher thermal performance when used in conjunction with 100mm layer between joists.
