As a plant-derived, natural fibre insulation, NatraHemp offers a vegan-friendly choice for environmentally conscious builds. Production takes place in the UK using domestically cultivated hemp, strengthening regional manufacturing and minimising carbon footprint.

NatraHemp exhibits vapour permeability and breathability, enabling it to regulate moisture during humid conditions and foster superior indoor air quality within building structures.

Installation & Handling

Thermafleece NatraHemp is non-toxic and straightforward to install. It poses no skin, eye, or lung irritation risks and requires no gloves or specialist protective gear during fitting. For work in sealed or poorly ventilated spaces such as attic areas, wearing a suitable dust mask is advisable.

To preserve breathability, pair NatraHemp with a moisture-permeable membrane or underlay.

Application Instructions / How-To Use

• Establish cavity dimensions prior to fitting
• Trim batts with a Stanley knife, insulation saw, or manual tearing for rapid installation
• For clean edges, sandwich the batt between 15 mm boards and cut along the protruding section
• Wedge the material securely between rafters, joists or studs for a tight seal
• Use scissors or shears to remove protruding fibres
• Layer multiple thicknesses when necessary to achieve target U-values
• Maintain complete coverage with no voids to maximise thermal and acoustic results

Storage Guidance

Keep insulation in a sheltered location away from ground contact. After opening, shield it from extended sunlight, moisture, or wet conditions to preserve its thermal properties.
