The number of BREEAM credits available from using Knauf Insulation’s Earthwool FactoryClad Roll played a part in its specification for Marks & Spencer’s flagship sustainable store at Cheshire Oaks.
Located near Ellesmere Port in Cheshire, this store is one of Marks & Spencer’s most sustainable stores. It was opened in Summer 2012 with over 148,000 square feet of selling space across two floors, parking for 950 cars, spaces for 100 bicycles and electric car charging points.
The store which has achieved a BREEAM ‘Excellent’ rating was designed to be the most carbon efficient premier store, with 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.
Gethin Williams, Euroclad’s Elite Systems Coordinator said: “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. Thanks to these many characteristics, we thought it was perfect for this project, which resulted in it achieving the relevant BREEAM credit. 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.
Gethin Williams at Euroclad concludes: “Our ongoing partnership with Knauf Insulation has resulted in us supplying significant tonnage of insulation per year, over various projects. Knauf Insulation’s product development is focused on the long-term, performance of its products and their environmental impact, which ultimately gives us the confidence to include in our specification.”
