Loft/Ceilings - Blown Wool

Superglass Superwhite 42 is a glass mineral wool blown loft insulation with a water repellent additive to enhance it resistance to moisture.

Superglass Superwhite 42 is designed specifically to provide thermal insulation in new or existing loft/cold roof spaces to a depth of up to 500mm. Blowing the insulation can be a better solution particularly in hard-to-treat lofts, where conventional rolls can’t be easily installed. Most mineral wool blowing machines can be used to install Superwhite 42 under the supervision of a professional company.
