Thermafleece NatraHemp fits securely between rafters, joists and studs providing excellent thermal insulation performance. Hemp is a fast-growing, low-impact plant crop that produces fine fibres suitable for insulation.  Thermafleece NatraHemp is a medium density insulation rich in home-grown hemp fibres and is a safe, efficient and durable alternative when plant fibre is the preferred choice.

Thermafleece NatraHemp can provide good acoustic insulation in a variety of systems.

Thermafleece NatraHemp is harmless and can be installed without gloves or protective clothing, although we recommend you wear a dust mask in enclosed spaces such as lofts. Thermafleece NatraHemp is not irritating to the skin, eyes or respiratory tract.
