What IndiNature does

IndiNature (legally Industrial Nature Ltd) is a UK manufacturer of bio-based insulation products, headquartered in Jedburgh in the Scottish Borders. Founded in 2016 by Scott Simpson and Sam Baumber, the company opened its flagship IndiNature Mill in November 2022 following a £3M investment from the Scottish National Investment Bank, with a second production line commissioned in 2024. As of the most recent disclosures, IndiNature is privately held, has raised over £5M cumulatively, and operates with 11–50 employees.

The company manufactures a range of natural fibre insulation products — IndiTherm, IndiBreathe Flex, IndiBoard, IndiSilence, IndiLoft, and i-joist backer blocks — made principally from UK-grown industrial hemp and recycled jute fibre, processed via airlay/thermobonding and carding/crosslapping/needle loom production lines. Its IndiTherm product is documented with negative embodied carbon (-0.79 kgCO2eq/kg) on a cradle-to-gate basis, and both IndiTherm and IndiBreathe Flex hold full BBA Agrément certification (2024), making IndiNature the only UK manufacturer with full BBA certification for natural fibre insulation. The company subsequently achieved ISO 9001:2015 (May 2024), IAA approval, the UK's first Ofgem Innovation Uplift for natural fibre insulation (May 2025), and Euroclass B-s1, d0 fire classification in tested timber frame systems (April 2026).

IndiNature generates revenue primarily through one-time sales of branded insulation products via a multi-channel distribution network: specialist insulation distributors (Ultimate Insulation, EcoMerchant, Ecological Building Systems), regional building materials merchants, OEM/white-label supply (Mayplas Thermapad), and integrated system partners (HEMSPAN BIOHAUS). End customers span architects, contractors, developers, self-builders, social housing providers (e.g. Renfrewshire Council), heritage and commercial projects (Duchy of Cornwall, Biorenewables Development Centre), and government-funded retrofit programmes (ECO4/GBIS). Pricing is quote-based through merchants; specific list prices are not publicly disclosed. A secondary B2B revenue stream has emerged from bespoke natural-fibre non-woven manufacturing using the second production line.

Revenue model

1. Natural Fibre Insulation Products: IndiNature generates revenue from the sale of its natural fibre insulation products including IndiTherm, IndiBreathe Flex, IndiBoard, IndiSilence, and i-joist backer blocks. Products are sold through distributors, merchants, and directly. The company also earns revenue from OEM/manufacturing for partners (e.g., Mayplas Thermapad). Sales are reported as growing threefold year on year, reaching just under £1M in the first two years of product sales (2022-2024).
2. Bespoke Natural Fibre Non-Woven Manufacturing: With the second production line, IndiNature manufactures custom natural fibre products for other brands and sectors including bedding, furnishings, acoustics, agriculture, and automotive composites. This represents a B2B manufacturing revenue stream alongside its own branded products.

Core offering

IndiNature manufactures and supplies natural fibre construction insulation products — flexible batts (IndiTherm), vapour-permeable batts (IndiBreathe Flex), semi-rigid boards (IndiBoard/IndiBreathe Boards), acoustic insulation (IndiSilence), and loft insulation (IndiLoft) — made primarily from UK-grown industrial hemp with some recycled jute. Production is carried out at the company's Jedburgh Mill using airlay/thermobonding and carding/crosslapping/needle loom lines, and the company additionally offers bespoke natural fibre non-woven contract manufacturing for partner brands.

Product overview

IndiNature offers a portfolio of natural fibre insulation products made from UK-grown industrial hemp and recycled materials. The core product range includes IndiTherm (pure hemp fibre flexible batt insulation), IndiBreathe Flex (recycled jute and hemp blend), IndiBoard (semi-rigid insulation boards), IndiSilence (acoustic insulation), and IndiLoft (loft insulation). These products work together as a comprehensive natural fibre insulation system for walls, roofs, floors, and lofts in both retrofit and new build construction. All products capture net carbon amounts, are vapour breathable, and are certified by BBA. The company operates the IndiNature Mill in Jedburgh, Scottish Borders, the UK's first dedicated natural fibre insulation factory.
