Sustainability
We’re committed to making the world a better, more sustainable home for everyone
At Isover we’re committed to creating a more sustainable future for all. From all electric equipment in our UK plant being powered by 100% renewable electricity, to cutting water consumption in our plants , we’re continually making improvements to deliver lasting impact.
We’re committed to making the world a better home for everyone, and delivering sustainable solutions that meet the needs of our customers.
Sustainable building materials
As we work towards becoming a world leader in sustainable insulation solutions, Isover brings together in-depth market knowledge and research to create more sustainable building materials that deliver their intended performance. For example, we provide thermal insulation that can help reduce energy consumption in buildings such as for heating up and cooling down.
Circular economy
Our Isover glass wool products manufactured in the UK contain recycled glass. This is a combination of 52% externally sourced recycled glass and 30% internally sourced glass cullet. In addition, in 2024, we became the first insulation manufacturer in the UK to partner with The Pallet LOOP, switching from disposable single‑use pallets to green timber pallets that can be collected and reused.
Recyclable packaging
Our new packaging design uses 30% post‑consumer recycled content and reduces ink usage to under 15% with a change to white base foil. This reduction means our packaging can now be used to produce a wider variety of items made of recycled content than before. This is because using a higher proportion of white plastic makes it more versatile.
By investing in innovative solutions and best practices, we’re continuing on our journey towards net zero carbon by 2050, demonstrating our commitment to sustainability and using resources in more considered ways.
Sustainability-driven operations
At our Runcorn facility in Cheshire, we’re continuing to deliver on our environmental commitments. All electric equipment in the plant is powered by 100% renewable electricity, whilst Runcorn has also been part of our water-saving programme, with advanced monitoring and metering to cut annual water consumption by 30 million litres. Plus our delivery fleet now uses HVO (Hydrogenated Vegetable Oil), a renewable fuel source.
