Hemp Blocks

Hempcrete is an amazing natural building material with many advantages unfortunately, there have traditionally been several issues which have restricted its wider use, such as requiring specialist knowledge, inconsistent supply and ultimately higher cost.

We have resolved these issues by using hemp blocks, which require no specialist skills or equipment, and by Partnering with Senini we have secured a regular high-quality supply, making the blocks more cost effective and available for more general use.

Why Build with Hemp Blocks?

Eco friendly
High insulative properties
Sound absorbing
Non-Flammable
Thermal mass
Carbon negative
Energy saving
Durable
Easy to use
100% natural

Hemp Block Uses:

Hemp blocks are the most accessible form of hempcrete, they are easy to use and require no special tools or machinery. They are light, easy to handle and with their size progress on site is very quick.

Internal or external solid wall insulation to existing properties.
New build walls around a steel frame or oak/ glu-lam feature frame.
New build walls in conjunction with a stud timber frame.
Floor insulation.
Roof insulation.
Internal wall where high acoustic performance is desired.
Intermediate floor insulation where high acoustic performance is desired.
Sensitive restorations

Are hempcrete blocks for you?

Are lower running costs more important to you than low cost up-front?
Is living in a healthy home with no chemical off-gassing important to you?
Are you concerned about the environmental cost of your material choices?
Would you like your home to clean up the atmosphere by capturing and locking up carbon?
Are you willing to adapt your design in pursuit of the above aims?

If you answer ‘yes’ to any above then hempcrete is for you, welcome aboard and give us a ring, we salute you and would really like to help.

Do you see new materials and an altered design as an inconvenience you could do without?
Is cost more important to you than the cost to the environment?
Is low up front build cost more important to you than low running cost?
Are you happy with using materials that produce huge amounts of Carbon in their manufacture that pollute the planet?

If you answered ‘yes’ to any of the above, then unfortunately hempcrete blocks are not for you, we wish you good luck with your project.

Eco Friendly

Our blocks are made of hemp shiv and hydrated lime. Hemp shiv is the chopped up woody stalk of the industrial hemp plant and is the waste from the hemp fibre industry. It is packed full of the carbon that the plant has taken out of the atmosphere during its growth.

When you build with our blocks you capture that carbon and fix it in the fabric of the building making our blocks carbon negative, as they have captured more carbon than it takes to produce and transport them. The advantage is doubled when you take in to account the carbon that would have been used to make the current insulation alternatives, making it a win, win.

The hemp shiv is mixed with hydrated lime, hydrated lime is made from burning and crushing limestone. Although this is an energy intense process the benefit of using hydrated lime is that it re-absorbs a lot of the carbon dioxide released during burning as it carbonates or sets, giving our blocks a further environmental advantage over other hempcretes.

This makes it more environmentally friendly than using hydraulic limes, or of course cement, which is burnt at a much higher temperature than lime and does not reabsorb carbon as it sets.

Both ingredients of our blocks are 100% natural and waste blocks or waste at the end of the building’s life poses no harm to humans or the environment.

IndiTherm Hemp Insulation

IndiTherm Hemp Insulation – Flexible thermal insulation ‘batts’ made from UK crops.

Insulation that you can friction fit between structural framing or against masonry – with excellent rigidity to resist slumping.

Healthy and soft to touch for installers. Very large carbon savings – net negative embodied carbon. Building occupants will benefit from the exceptional thermal and moisture buffering properties of this sustainable material. It has the added property of low-density heat storage, which means indoor temperatures stay warm in winter and cool in summer. Durability tested.

Benifits of IndiTherm Hemp Insulation

Sustainable: IndiTherm batts are made from natural fibres sourced from crops grown in the UK, making them an eco-friendly and sustainable insulation material. They are carbon-negative, meaning that they capture more carbon than is produced during their manufacture.

High Thermal Performance: IndiTherm batts have low thermal conductivity and moisture-buffering properties, which help to maintain comfortable indoor temperatures all year round. They are designed to reduce heat loss and improve energy efficiency, which can result in lower energy bills and more comfortable living spaces.

Healthy Indoor Air Quality: IndiTherm batts are soft to the touch and support healthy indoor air quality. They are vapor breathable, which means that excess moisture can be transported out of buildings, reducing the risk of dampness and mould growth.

Easy to Install: IndiTherm batts are flexible, easy to handle, and can be friction-fit between structural framing or against masonry. Their exceptional rigidity resists slumping, which means that they maintain their effectiveness over time.

Durable: IndiTherm batts have been tested for durability under extreme conditions and are an excellent insulation solution that reduces waste while keeping buildings dry. They are recommended by Historic Scotland and Historic England because they help preserve buildings by keeping structures dry.

Storage

• Product must be kept dry during storage and delivery.
• Pallets must not be stacked.

Hemp Insulation by IndiNature

UK Grown – Sustainable – Multi Use – Carbon Locking

Hemp Insulation is a natural and sustainable way of insulating your property. A whole range of sustainable building products made from hemp are available for use in restoration and new build projects. Hemp construction uses renewable crop-based materials that absorb carbon dioxide (CO2) as they grow, providing an opportunity to capture and store CO2 in the fabric of buildings.

HempBuild Building Shiv

Natural Hemp Shiv made from UK crops.

Hemp construction uses renewable crop-based materials that absorb carbon dioxide (CO2) as they grow, providing an opportunity to capture and store CO2 in the fabric of buildings for their entire lifespan. Sustainable building products are being made from all parts of the hemp plant and are ideal for use in both renovation and new build projects. Hemp fibre can be made into “user-friendly” recyclable loft insulation which does not contain any harmful ingredients and compressed hemp shiv is used to make fibreboard, but by far the most exciting development is hemp lime plaster and hempcrete, an insulating material that can be used for construction.

Breathability

Hemp-lime composite materials absorb moisture vapour and allow it to pass through the fabric of the building; This effect is known as ‘breathing walls’. Structures built from non-breathable materials can trap moisture, which is very likely to cause mould growth, particularly if there is insufficient ventilation and high levels of condensation. Breathability also helps to protect the fabric of the building, particularly against decay in the timbers.

Hemp and lime masonry construction is unique because it provides a method of building which is structurally sound, can provide thermal and acoustic insulation, thermal mass and storage but can also be used as the external skin of a building. It is extremely simple to construct, using just one method to meet many very different requirements for walls, floors, and even roofs.
