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.

Installation

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