We’re committed to making the world a better, more sustainable home for everyone

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.

I have severe allergies, and my contractor is installing Isover. What’s in the product?

We are unable to provide specific case advice – however, please refer to our Safe Use Instruction Sheet (SUIS), a link to which you’ll find below. Our product contains less than 1% mineral oil, which is added to reduce dusting of the glass mineral wool.

Does your insulation contain palm oil?

No. Isover insulation does not contain palm oil.

Is Isover packaging recyclable?

Yes. In 2025, we also reduced the ink coverage in our white packaging to less than 15%. This reduction means our packaging can now be used to produce a wider variety of items made of recycled content than previously. This is because using a higher proportion of white plastic makes it more versatile. Our packaging also contains 30% Post Consumer Recycled content, which means less raw virgin materials go into our packaging and further strengthens our commitment to sustainability.

Do you recycle leftover insulation?

Isover doesn’t currently offer a customer recycling service. If you do need to dispose of leftover insulation, residues or by-products, this should comply with the requirements of environmental and waste disposal legislation and any local authority rules.
