IndiTherm Insulation made from UK-grown Hemp - IndiTherm is a high-density, flexible Natural Fibre insulation made from Hemp. Suitable for most situations where flexible insulation is used, such as roof spaces, suspended floors, timber-frame walls, etc.
Though IndiTherm is a flexible insulation, its high density makes it rigid enough to "friction fit" between structural framing. This makes IndiTherm particularly well-suited for areas where insulation can be prone to slumping, such as walls, or where work is above your head during installation.
As with most natural fibre insulation, it's non-itchy and easy to handle. This makes installation even easier for the installer.

Ordering & Delivery Charges
Stocked and delivered on our behalf by the manufacturer, IndiNature.
Key Benefits
- Carbon Negative: Hemp captures 15-20 tonnes of carbon per hectare every year grown. The energy required to manufacture is relatively low, making the end product carbon-negative.
- Vapour Open - Naturally regulates humidity, reducing the risk of damp and mould, promoting healthy indoor air quality.
- UK Grown and Manufactured - helps reduce carbon emissions from long-distance transportation.
- Friction Fit Installation: Fits between timber studs/joists. Like most other flexible insulations, IndiTherm has the advantage of being more rigid than comparable products. The increased rigidity reduces slumping and increases ease of installation.
- Installation - IndiTherm insulation is non-itch, soft to the touch and easy to handle. As with any insulation fitting, we recommend wearing a mask during installation.
Technical Details
- Thermal Conductivity - 0.04 W/mK
- Density - 45kg/m³
- Carbon Negative - Net storage of -0.7 kg CO2 eq/kg
- Specific Heat Capacity - 2100 J/(kgK). A high heat capacity helps rooms stay warm in winter and cool in summer. Generally, Natural Fibre Insulations excel here versus synthetic alternatives.
- Fire Rating - E (Euroclass Fire Rating), tested to BS EN 13501-2 | Euroclass B-s1, d0 reaction to fire classification when used as part of a tested timber frame system with a plasterboard lining in accordance with EN 13823 (Single Burning Item)
- Vapour Diffusion Resistance μ - 2, tested to BS 5250:2011 + A1:2016
