Thermafleece NatraHemp 100mm Hemp Insulation Slabs

Thermafleece NatraHemp - British Hemp Plant Fibre Insulation

This 100mm x 570mm natural insulation solution harnesses British-grown hemp fibres for sustainable, high-performance thermal protection across UK construction projects. Hemp represents a rapidly renewable crop with minimal environmental footprint, yielding premium fibres ideal for insulation applications. The 100mm x 570mm NatraHemp slabs combine a rich hemp fibre blend with thermal bonding technology to maintain structural integrity and prevent material degradation throughout the product's lifespan.

Engineered for straightforward installation between rafters, joists, and studs, these 100mm Thermafleece NatraHemp insulation slabs deliver robust thermal performance across multiple building scenarios. At 28 kg/m³ density, NatraHemp simultaneously provides excellent acoustic properties, effectively dampening sound transfer through building elements including walls, floors, and roof assemblies. Incorporating NatraHemp into your construction strategy substantially improves thermal efficiency and reduces operational heating expenditure.

As a plant-derived natural fibre insulation, NatraHemp delivers an animal-free alternative suited to environmentally responsible construction schemes. Manufacturing takes place within the UK using domestically cultivated hemp, strengthening regional supply networks and minimising carbon impact.

NatraHemp functions as a vapour-permeable and breathable material, enabling it to regulate moisture levels during high-humidity conditions and foster improved indoor air quality within building structures.

Installation & Handling

Thermafleece NatraHemp presents a non-hazardous, user-friendly installation experience. The material causes no skin, eye, or respiratory irritation and installs comfortably without gloves or specialist protective gear. For work in sealed or poorly ventilated spaces such as attic areas, wearing a suitable dust mask and appropriate PPE remains advisable.

To preserve breathability characteristics, pair NatraHemp with a moisture-permeable underlay system.

Application Instructions / How-To Use

• Measure the cavity width before installation
• Cut the batts using a Stanley knife, insulation saw, or by hand tearing for quick fitting
• For precise cuts, compress the batt between 15 mm boards and saw along the overhanging edge
• Press the insulation firmly between rafters, joists or studs to ensure a secure fit
• Use scissors or shears to trim loose fibres
• Install in layers if multiple thicknesses are required to meet specific U-values
• Ensure full coverage without gaps for optimal thermal and acoustic performance
