Superwhite 42 – Loft Blown Wool

Description

Superglass Superwhite 42 is a glass mineral wool blown loft insulation with a water repellent additive to enhance it resistance to moisture. Installed by professional insulation contractors to a minimum density of 16kg/m3 the product will have a declared Lambda 90/90 value of 0.042W/mK.

Application

Superglass Superwhite 42 is designed specifically to provide thermal insulation in new or existing loft/cold roof spaces 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.
