Hemp Insulation: Thermafleece NatraHemp Insulation

Hemp insulation: Thermafleece NatraHemp is a medium density hemp insulation rich in hemp fibres. It is a safe, efficient and durable alternative when plant fibre is the preferred choice.

Hemp is a fast-growing, low-impact plant crop that produces fine fibres suitable for insulation.

Thermafleece NatraHemp natural insulation fits securely between rafters, joists and studs providing excellent thermal insulation performance. What’s more, with a density of 25 kg/m3, Thermafleece Natra Hemp insulation can provide good acoustic insulation in a variety of systems.

To retain the benefits of water vapour, absorption and release, Thermafleece NatraHemp may be used in conjunction with a vapour permeable underlay. Protect the insulation from prolonged exposure to sunlight when unpacked and avoid wetting for extended periods, store under cover and clear of the ground.

Why Insulate With Thermafleece NatraHemp?: Insulating a property will significantly lower the amount of energy lost from the building envelope, reducing energy consumption and carbon dioxide released to the atmosphere.

Performance: With a Thermal Conductivity of 0.040 W/mK, Thermafleece NatraHemp provides a better level of performance compared to low density insulation.

Cost Effective: Energy savings from using Thermafleece NatraHemp meaning it can pay for itself in a few years.

Long Lasting: Thermafleece NatraHemp contains a lofting agent to maintain fibre stability and structural integrity throughout.

Sustainable: Using Thermafleece NatraHemp can reduce your carbon emissions by many tonnes over the lifetime of use. The hemp fibres fix carbon dioxide further helping reduce greenhouse gas levels.

Safe: Thermafleece NatraHemp is safe to handle without the need for personal protective equipment. It can be recycled or safely disposed of at the end of its life
