A Natural & Sustainable Insulation

Hemp insulation is made from the hemp plant. The raw plant material is manufactured into hemp wool, which is formed from strong and woody fibres that prove to be an excellent insulation material. Used throughout history in ropes, sails, construction and agriculture, only recently have specialists discovered the benefits of using hemp for loft insulation. 

The hemp plant is fast-growing and requires very little water, making it a sustainable and renewable source of insulation. Once the lifespan of hemp insulation has come to an end, it is fully biodegradable and doesn’t release harmful volatile organic compounds (VOCs) unlike traditional insulation materials. 

To put it simply, hemp insulation is sustainable, renewable, and fully biodegradable. 

Even better, hemp’s lifespan is far longer than traditional insulating materials like fibreglass, polystyrene, and mineral wool, lasting for up to 100 years. It’s guaranteed to last the lifetime of your home, making it a cost-effective and environmentally friendly alternative.

Perfect For Period Properties

Installing loft insulation in period properties is notoriously difficult. Older attics are often confined and have awkward angles, uneven surfaces, and ventilation issues. Hemp is not only breathable but also hygroscopic, actively regulating moisture so your loft space can enjoy natural air circulation while staying extra warm in the winter. Hemp’s flexibility also makes it easy to fit around beams, joists, and any hard-to-reach areas.

Benefits of Hemp Insulation

Choosing hemp insulation will keep your home warm, improve the breathability of your loft, and keep the planet happy.

Highly Sustainable

Hemp is one of the most sustainable insulation materials out there. This rapidly renewable plant grows in just 3-4 months, requiring minimal water, no pesticides, and little maintenance. By choosing hemp insulation, you’re opting for a low-impact material that promotes environmental health from growth to installation.

Fully Biodegradable

Unlike synthetic insulation options, hemp insulation is fully biodegradable at the end of its life cycle. Once removed, it breaks down naturally and can even be composted, making it a zero-waste choice that minimises the impact on the planet over the long term.

Unparalleled Thermal Performance

Hemp insulation offers superb thermal performance, helping your home stay warmer in winter and cooler in summer. With its dense fibre structure, it easily retains heat, so you don’t need to keep the heating on. With hemp, you will save on your energy bills year-round.

Moisture Regulation

Hemp fibres are hygroscopic, naturally absorbing and releasing moisture, keeping insulation effective without compromising its structure. This moisture-regulating quality prevents damp and mould buildup in your loft, so you can enjoy a healthy, stable, and dry home.

Breathable

Hemp insulation allows your loft space to breathe. This helps prevent condensation, protects the building fabric, and promotes better air quality by allowing moisture to move naturally through your attic.

Full Soundproofing

Because of its density, hemp insulation provides excellent soundproofing. It reduces noise transmission between floors and rooms, creating a quieter home– without missing out on the benefits of natural insulation.

Pest Resistance

Hemp is naturally resistant to pests and rodents, unlike many organic materials. Once installed, it doesn’t attract insects or vermin, so you won’t need to invest in pest treatments.  It’s a safer and more sustainable insulation solution.

Quick & Easy Installation

Hemp insulation is flexible and soft, making it easy to cut, handle, and install. It doesn’t require any specialised equipment or intensive safety precautions, which means installation is often quicker, more straightforward, and easy to fit in tight loft spaces.

100-Year Lifespan

Hemp insulation is impressively durable, with a lifespan of up to 100 years. Its natural resilience and low tendency to degrade make it a sustainable and cost-effective insulation choice, providing decades of heat retention and long-term value.

This guarantee is insurance backed by the Independent Warranty Association.

How Does Hemp Insulation Work?

Hemp is one of the most effective insulation materials out there because of its unique fibre structure, which naturally traps air and slows down the movement of heat. Just as a jumper helps you hold on to body heat, hemp insulation creates a barrier against heat loss to stabilise your indoor temperatures.

Hemp fibres are known for their hygroscopic properties,  allowing them to be excellent at regulating moisture without compromising on insulation. Because it’s breathable, installing hemp insulation prevents the buildup of condensation which is common in traditional insulation materials like fibreglass. 

Even better, hemp’s density makes it an effective soundproofing material, helping to reduce noise transmission, so you can enjoy a quieter and more relaxing home. 

One of the most sustainable insulation materials, hemp insulation is fully biodegradable meaning it’s not only great at keeping your home warm, but it’s also environmentally friendly and an eco-friendly choice for your loft space.

Approved Hemp Insulation Installers

You may be wondering if our service is truly trustworthy. To assuage any concerns, several organisations have glowingly approved our service. RJ Insulation is Which? and Trusted Trader Approved. 

We held the PAS 2030:2019 accreditation for the installation of insulation in 2022, which also covers cross-flow ventilation. Our installation team also conformed to PAS 2035:2019 for a year. We chose not to reinstate the accreditation because ECO4 would only allow fibreglass to be installed, which isn’t biodegradable and doesn’t fit our ethos.

In short, you can trust us for your insulation installation needs. Our friendly team always encourage you to make the most informed decisions about your preferred insulation through our online questionnaire.

From the initial call to the completion of the job, it’s been a pleasure to deal with RJ Insulation. After the survey, we were given a quote almost straight away but no hard sell or pressure attached to it. The date for installation was agreed. Two lovely guys turned up to fit the foil in the loft, both were very polite and courteous at all times. Dust sheets were put down and they hoovered up at the end of the job both days. I would recommend this company to anyone who’s thinking of having new loft insulation put in. You won’t get better than this, genuine people that take pride in what they do, a rare commodity these days.

R&J completed a loft conversion project for me in September 2021. From pre-sale to implementation, the experience of doing business with them was exemplary. Ron led us through a thorough, inclusive design process, where he and Max offered polite suggestions based on their experience, but always ensured we were getting exactly what we wanted. The statement of work and price breakdown were crystal clear, and they stayed in constant communication until the job was complete. Max and the rest of the install team carried out extremely high quality work, with great care and consideration, and the end result was absolutely perfect. It is clear that the whole team takes pride in the quality of the outcome they deliver, and it was an absolute pleasure to use their service. I would highly recommend R&J to anyone considering any kind of loft conversion work, they will not let you down.

Treated our home like theirs. Friendly, polite and great workmanship all the way. We are so pleased with the results. Highly recommended the team.

We recently moved to a new property with a walk in loft plus a shallow loft at the apex of the house. The walk in loft was very draughty especially in windy weather. We could also hear every word spoken in the loft clearly in the kitchen/rooms below. We thought the SuperFOIL product would be perfect, as we’d read that many mortgage companies will not give a mortgage on foam products fitted between the joists making the property hard to sell. We contacted R J Insulations and were impressed with their Surveyors (initial quote and follow up prior to installation) and with the communication from the sales office. The installation team (3 guys) were brilliant. So organised. They prepared our house with sheeting to cover walkways, were informative about every stage of the installation and were so polite. The installation took 2 days. We had SuperFOIL on the joists in the walk in loft and SupaSoft between the rafters and also SupaSoft between the rafters in the apex loft space. The first thing we noticed was the reduction in noise – the SupaSoft

    FAQs

    Hemp Insulation Installation FAQs

    Hemp is a much more expensive material than fibreglass to have installed in your home, however, its long-term cost savings make it a cheaper insulation option. Hemp insulation has a lifespan of up to 100 years, whereas fibreglass lasts for just 30 to 50 years, meaning it will insulate your home for twice as long (or more)! It also performs better while averting moisture build-up and allowing for natural air circulation in your loft. 

    If you’re concerned about the cost of hemp insulation, contact our friendly team today. We’d be happy to give you a free, no-obligation quote for your loft space.

    Both hemp insulation and sheep’s wool insulation are equally great at keeping your home warm, mainly because they’re both natural insulators. Both materials work by trapping air within their fibres, creating a barrier that protects against heat loss. 

    They’re also both hygroscopic meaning they’re both incredibly efficient at absorbing moisture and preventing dampness. Ultimately, whether sheep’s wool or hemp insulation is better for you depends on whether you’re vegan or not. 

    If you’re not vegan, we recommend Sheep’s Wool, but if you are, then Hemp is the best choice for your home. If you’d like to talk through your options, contact our friendly team today.

    Yes, hemp is a medium-density insulation material with low conductivity and a high thermal mass. In other words, it makes very effective insulation! It can easily retain heat, soak up moisture to prevent dampness, and is renewable, meaning your home not only stays warm but is friendly to the planet.

    Hemp insulation is very efficient at keeping homes warm in winter and cool in summer. Its dense fibres trap air, creating a natural barrier against heat loss. This means less energy is needed for heating and cooling, which can lead to lower energy bills. Hemp is also moisture-resistant and breathable, making it highly effective at regulating indoor humidity for a healthier environment.

    Hemp insulation can be more expensive upfront compared to some traditional insulation materials like fibreglass or mineral wool, but the long-term benefits make it worth it. Its durability and high performance can lead to hefty savings on energy bills, and its eco-friendly nature adds extra value to your home. Plus, since it can last for up to 100 years, it often pays for itself over time.
