Product Details

Earthwool Loft Roll 40 is a flexible glass mineral wool quilt which is lightweight, flexible, resilient and non-combustible. The rolls are 1140mm wide and are either partially perforated or fully cut to produce either 2 rolls 570mm wide or 3 rolls 380mm wide.

Earthwool Loft Roll 40 is primarily used for the thermal insulation of pitched roofs at ceiling level. However, it can also be used to thermally insulate floors and partitions, or wherever a lightweight mineral wool quilt is required.
