Superwhite 42 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 14.5kg/m³.

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.

Installation

Most mineral wool blowing machines can be used to install Superwhite 42 under the supervision of a professional company.

Performance
