Hemp insulation is a completely natural form of insulation, crafted using fine hemp fibres. Due to its low-impact manufacturing process, it is one of the most sustainable types of insulation available. In fact, as hemp fibres naturally retain CO2, using this insulation in your home will prevent tonnes of carbon emissions across its lifetime.
Along with its sustainability, hemp insulation is also highly versatile. It can be used to insulate walls, floors, and roofs, fitting snugly between rafters, joists, and studs. Thanks to its natural construction, you won’t need to wear any PPE when installing hemp insulation, even when cutting it.
As hemp fibres are naturally fine, they can be woven into a tightly-packed slab of insulation. With a density of 25kg/m3, hemp insulation offers excellent acoustic performance, ideal for homes where noise may be a concern. Plus, due to the way hemp manages moisture in the air, your home’s internal air quality will also improve.
You’ll also save plenty of money on utility bills, due to hemp’s fantastic thermal performance (thermal conductivity of 0.040 W/mK). So, if you’re looking for a safe, reliable, and eco-friendly alternative to traditional loft insulation, hemp could be just the thing for you.

What Is Hemp?
Hemp is a variety of the Cannabis Sativa plant grown specifically for industrial use. Its strong, woody fibres are ideal for a variety of purposes, including insulation. As hemp wool has incredibly low levels of thermal conductivity, it’s an ideal natural insulation material. Plus, hemp naturally draws CO2 and other impurities from the air, contributing to a healthy home environment. Due to its resilience, hemp can be grown in almost any soil under a wide range of conditions and is one of the fastest growing plants on Earth.
What Are the Advantages of Hemp Insulation?
Hemp insulation has many advantages, which make it easy to see why this insulation material is growing so quickly in popularity.
- Excellent thermal and acoustic performance
- Low levels of embodied energy
- Fully recyclable at the end of its lifespan
- Draws CO2 and other pollutants from the air
- Not irritating to human skin or lungs
- Contains no hazardous materials
- Regulates moisture content in the air
What Are the Disadvantages of Hemp Insulation?
Hemp insulation does have a few drawbacks however, which we’ve listed below:
- Poor performance against high levels of excess moisture
- Contains non-renewable polyester binder (10%)
- Unproven, not as much testing as other materials
What Is the R-Value of Hemp Insulation?
Hemp insulation has an R-Value of 3.5 per inch of material thickness.
Is Hemp Insulation Flammable?
Hemp insulation is flammable; however, it is fire-resistant, meaning it will resist flaming and prevent the spread of fire for up to three hours. All of the hemp insulation we sell passes the standards of BS EN 5803-4.
