Sustainable insulation company achieves a UK first

IndiNature, based in the Scottish Borders, has become the first UK company manufacturing industrial hemp insulation to achieve a full agrément certificate from the British Board of Agrément (BBA).

This means that the company’s insulation products can now be used by the housing and construction sectors at scale for both newbuild and retrofit projects.

IndiTherm was established in 2016 to make sustainable insulation materials on a commercial scale to help decarbonise construction.

The industrial hemp is sourced from East Yorkshire Hemp and IndiNature aims to help re-grow the local supply chain for industrial hemp over the coming years by working closely with farmers close to its base in Scotland.

The company’s CTO, Scott Simpson, was studying sustainable architecture at the Centre for Alternative Technology and carried out lab-based research into natural insulation materials. He used his family home as a case study; rebuilding and extending it using the best natural materials available.  The three-bed home now has energy bills 25% of the average and keeps humidities and temperatures even, comfortable and healthy all year long.  However, he found the products were hard to source, expensive and had to be imported.  Now, with IndiTherm certified, hemp-based batts can be used in many applications as a simple alternative where conventional mineral wool insulation is used in construction such as open timber frame studs, roofs and floors.

Scott said:

Our whole team feels proud to have worked with the BBA to achieve the only agrément certificate currently in the UK for industrial hemp insulation – and even more proud of the fact the products are made by local workers in our mill and the fibres are supplied by local farmers. This means carbon captured by British farms can be stored in British buildings.

We founded the business because we care about quality buildings, people’s health and the planet – a full BBA agrément certificate will help us grow those positive impacts on scale. Securing an agrément is a highly demanding and rigorous process for any company – as a start-up this been even more of a challenge but has meant we have optimised our in-house controls and are continuously improving product performance. It’s been tough for the team to get to this stage but we feel great about achieving our first certificate. The trend for natural low carbon construction materials continues to grow – this is an exciting time for IndiNature as we help accelerate that supply.

Alex McLeod, IndiNature’s new CEO added:

To have BBA certification demonstrates that our products have been tested to the highest standards expected here in the UK, and will undoubtedly assure architects, builders and contractors that our products are not only sustainable but achieve required performance levels.

We are currently the only UK manufacturer of natural fibre insulation products to be accredited with a full BBA agrément certificate and this is already proving to be very positively received by our current and potential clients.  We are now well placed to offer a range of unique carbon-negative insulation materials with the peace of mind that our products have been tested to the highest standard.  

 I’d like to thank the team at BBA for their diligence and rigour through the process and we look forward to working with them again as we expand and develop our product range.
