IndiBoard® natural fibre insulation

Breathable. Sustainable. High-performance.

IndiBoard is a semi-rigid, multi-purpose insulation board made from industrial hemp - providing excellent thermal performance with natural breathability. Its vapour-open design safely releases excess moisture, keeping surrounding materials dry and helping to preserve the building fabric over time.

Suitable for use as an internal insulation board, IndiBoard can be applied in both retrofit projects and new-builds. It can be fixed directly to the wall and covered by plasterboard or lime plaster.

Occupants benefit from a complete, moisture-regulating thermal envelope that improves indoor air quality, comfort, and energy efficiency year-round.

Key Benefits:

• Made from sustainable UK-grown hemp
• Vapour-open and moisture regulating
• Reduces thermal bridging for consistent warmth
• Carbon negative with net carbon storage

Installation:

Keep product dry during storage and handling.

Cut using wave-form insulation blades (handsaw or powered dual-blade reciprocating saw). Refer to the installation guide for full instructions.
