Knauf insulation materials were chosen to insulate one of Marks and Spencer’s most carbon efficient premier stores.

The project took a holistic approach taken towards key sustainability factors such as water, carbon, biodiversity, the community, materials and waste to landfill.

Knauf Insulation’s Earthwool® FactoryClad Roll 40 was utilised within the 11,000m2 multi-wave form standing seam roof, which was supplied by Euroclad to achieve an outstanding visual, functional and environmentally friendly element of the store design, plus achieving a BREEAM ‘Excellent’ rating. The number of BREEAM credits available from using Knauf Insulation’s Earthwool Factory Clad Roll 40, played a part in its specification for Marks and Spencer’s flagship sustainable retail store at Cheshire Oaks.

Earthwool FactoryClad Roll 40, in 280mm, has a 90/90 lambda value, a generic BRE Green Guide rating of A+ and has excellent thermal and acoustic properties. Being lightweight, flexible and with a high tear strength, fitting was fast and error free, ensuring the thermal integrity was uncompromised.

Knauf Insulation’s Earthwool FactoryClad Roll 40 is manufactured with ECOSE®Technology, has a thermal conductivity of 0.040W/mK and also has the highest possible Euroclass A1 reaction to fire rating when tested in accordance with BS EN 13501-1.

In addition to this, Knauf Insulation’s mineral wool products with ECOSE Technology benefit from a revolutionary, bio-based, formaldehyde-free binder technology, based on rapidly renewable materials, instead of petro-based chemicals – delivering superior environmental sustainability and enhancing the environmental credentials without affecting the thermal, acoustic or fire performance. What’s more Earthwool FactoryClad Roll 40 represents no known threat to the environment and has zero Ozone Depletion Potential and zero Global Warming Potential.
