Knauf Insulation Rolls

Knauf Insulation (Rock & Glass Products) designed its loft insulation products specifically for the thermal insulation of attic and cabin spaces. For example, if you are insulating at ceiling level (above or between joists), they have a suitable product: Earthwool® Loft Roll 40 - these unfaced loft insulation products are made just for merchants and distributors to keep on hand before handing them off to the customer. They'll retain their shape even after spending weeks on end exposed to sunlight!
