Thermafleece NatraHemp is made using hemp, a low-impact plant that is suitable for insulation. Using hemp fibres grown in the UK, NatraHemp is an efficient, long-lasting and environmentally friendly alternative to traditional insulation. It is ideal for use in rafters, joists, and studs and it fits in securely whilst also providing a strong thermal insulation performance.

NatraHemp is completely harmless, so you won't need any protective clothing to install it, although it is recommended to wear a dust mask if working in an enclosed area, such as a loft. Unlike traditional loft roll insulation, NatraHemp won't irritate the eyes, skin or respiratory tract.
