Manufacturing Process

The manufacturing process of Inno-Therm®/Métisse® allows us to limit the use of natural resources. For the product’s raw material we use recycled cotton textiles which are at the end of their life – 85% of fibres from recycled cotton and 15% PES (Polymer binder). Of the recycled cotton portion, over 85% is from recycled denim fibres.

The origin of the fibre component Inno-Therm®/Métisse®, recycled cotton from clothing “at the end of its life” fully leached over time, does not contain any VOC emissions (TCOV rate below the detection limit of 2 μg / m3 – test certified according to the standards in force). Inno-therm®/Métisse®, insulation is guaranteed to be free from fungal growth (as part of the certification test according to standard NF EN ISO 846). By the nature of its textile fibre, Inno-therm®/Métisse® insulation is recyclable after the building has been deconstructed.

The sorting process accounts for less than 0.5% of the energy used in production. Sorting by hand allows not only to limit energy consumption but also to offer social benefits in the manufacture through job creation.

The process uses around 3 pairs of jeans per square metre of insulation at 100 mm thickness!

The manufacturing steps for Inno-Therm®/Métisse®

VNR produced in 2011 by Mostra, for free distribution to European TV networks for EC/ DG Environment. The VNR focused on “resource efficiency” and “waste as a resource”. The insulation is not made in Rochdale. In July 2013, production of Inno-Therm®/Métisse® was transferred to Le Relais.

Recovery Insulation and Le Relais recycles our old jeans into thermal and acoustic insulation for our home and music studios

Le Relais is the French leader in the recovery of used clothing. Le Relais had the idea of developing insulation with unsaleable textiles in its network of thrift stores. It is called Métisse® and in the UK the brand is called Inno-Therm®/Métisse®, This low carbon insulation ranks among the best performing on the market following principles of the “circular economy” in manufacturing,
