Sustainability
We care for the people who make our products, the people who use them and the world we all depend on

As the market leader and a non-stop innovator, quality excellence and sustainability are at the heart of everything we do; whilst we have a strong focus on the thermal, fire and acoustic performance of our products, our pursuit of sustainability has much wider horizons.

Whilst we are dedicated to supplying sustainable high performance insulation solutions for enhanced energy efficiency in buildings, we also continually strive for improvements in our manufacturing and supply chain operations to improve quality and minimise our impact on the environment. All Knauf Insulation production locations have state-of-the-art manufacturing equipment and meet the highest quality standards, supported by an ongoing research and development program.

Raw Materials

Our Glass Mineral Wool insulation solutions contain up to 80% of recycled materials, the majority of which comes from the recently opened Veolia Glass Cullet facility. By maximising the amount of recycled glass cullet in the manufacture of our products, we minimise our need for mineral raw materials.

Our revolutionary bio-based binder, ECOSE® Technology avoids the use of petrochemicals. It is 70% less energy intensive than traditional binders, reducing energy consumption and CO2 emissions at our manufacturing facilities.

Our work to ensure safe and legal operations in our supply chain has enabled us to achieve certification to the Building Research Establishment's responsible sourcing standard BES 6001.

Manufacturing

Partnering with Siemens, we are unlocking efficiency opportunities to reduce our carbon footprint, saving the equivalent annual energy usage of almost 800 homes.

Our commitment to fair and safe working practices in our own facilities is embedded in our code of conduct, and reflected in the OHSAS 18001 certification covering all our production sites.

All our facilities are also certified to ISO 14001 and ISO 50001 standards.

We avoid waste and prevent pollution; we segregate factory waste to maximise recycling and to meet our
expectation of sending zero waste to landfill from our
UK plants.

Packaging & Distribution

Our industry-leading compression-packaging technology allows us to load more product onto each truck that leaves our factories. This means less packaging, fewer vehicles on our roads, so less CO2 emissions. It also means less storage space required for our customers. 

We have recently been trimming the weight of the pallets we use in the UK, cutting around 2kg per pallet, equating to a total saving of around 5,000 trees/year.
