Knauf Insulation has launched FactoryClad Roll 35, a non-combustible glass mineral wool solution for built-up metal walls and roofs with some of the lowest embodied carbon of any equivalent 35 lambda mineral wool product on the UK market.
FactoryClad Roll 35 was specifically developed to insulate the 12,000m2 roof of the new Co-op Live arena in Manchester, one of Europe’s largest and most sustainable live entertainment arenas.
“Co-op Live is a project that places sustainability at its heart,” explained Liliya Luke, Glass Mineral Wool Product Manager at Knauf Insulation. “So it was essential our new FactoryClad Roll 35 not only delivered the required thermal efficiency but met the project’s sustainability requirements.”
“We know that the construction industry faces a monumental task in delivering on the country’s net zero target. FactoryClad Roll 35 not only ticks all the boxes in terms of thermal, fire safety and acoustic performance but it’s backed up by the sustainability credentials the industry needs, so we decided to roll it out to meet demand for sustainable insulation for commercial buildings.”
FactoryClad Roll 35 is non-combustible with the best Euroclass A1 reaction to fire classification. Because it is made of mineral wool, it also acts as a sound absorbent lining within built-up metal roofs, so will help control the reverberation of internal sound.
It comes in five thicknesses between 60 and 220mm and is manufactured at a width of 1,200mm for speed of fitting. It also has a high tear strength which ensures its durability and ease of handling during installation.
FactoryClad Roll 35 is backed up by a wide range of sustainability credentials. It’s manufactured with ECOSE® Technology, Knauf Insulation’s unique bio-based binder that contains no added phenol or formaldehyde and is 70% less energy-intensive to manufacture than traditional binders. Products made with ECOSE® Technology generate low levels of dust and low VOCs and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort.
All Knauf Insulation’s glass mineral wool is made using up to 80% recycled content, mainly bottles and jars collected from the local area. The company has also invested in the most advanced compression packaging, which reduces handling, storage and transport emissions as well as the amount of plastic film used. In addition, the products are manufactured in the UK.
Like other Knauf Insulation glass mineral wool products, FactoryClad Roll 35 is accredited Declare ‘Red List Free’. This means there is an obligation to disclose a full list of product ingredients up to 0.01% and it certifies that the product does not contain any harmful chemicals featured on the Declare ‘Red List’.
