Sustainable building and renovating with Hempbuild Isohemp hempcrete blocks.

The selection of construction materials in your project is of primary importance. Building performance, ease of implementation and the impact on the health of occupants are criteria that will guide your choice.

You have a building or renovation project and of course you want a solution without compromises? Benefit from the many advantages of walls made of Hempbuild Isohemp hempcrete blocks: a healthy and warm atmosphere, optimum thermal and sound insulation, moisture regulation, fire resistance, etc.

The key advantages of Hempbuild Isohemp hempcrete blocks.

  • It has great energy efficiency.
  • It maintains a steady temperature.
  • It is a breathable material.
  • It provides a healthy environment.
  • It’s very simple to use if you follow the process correctly.
  • It gains in strength over time.
  • It can be used seamlessly around the building to create an airtight layer.
  • It has the versatility to be used in floors and roofs.
  • It’s hygroscopic, so absorbs moisture and humidity within the building.

renovations & refits

From Farmhouses & Barns to Victorian Dwellings.

When renovating, we recommend to use breathable materials that are resistant to condensation and do not release any volatile organic compounds. Hempcrete blocks sustain the existing building and regulate the moisture in the air on a continuous basis thanks to a breathable wall that is permeable for water vapour. The blocks are placed as a second lining to the interior wall and allows, among other things, to isolate old brick/stone walls or damp walls. It is one of the only products that retains its insulating properties even in a very moist environment. Wooden floors are safe from condensation.

High performance thermal insulation

In winter as in summer, you want to maintain a constant and pleasant temperature inside your building. The hempcrete block lets you achieve this by naturally regulating the temperature of your house thanks to its capacity to diffuse accumulated heat. Its great inertia helps protect from cold in winter and hot in summer.

Eliminate Thermal Bridges

Stop the cold coming through the walls by eliminating thermal bridges and potential condensation problems (dew points). Moisture regulation between old and new materials. The non-flammable hempcrete blocks are fire resistant for up to 3 hours.

Ease of implementation – Straight Walls.

Their size and their easy installation on site allow you to work quickly with our Isohemp hempcrete blocks. The inner walls allow you to correct uneven walls that are strong enough to hold heavy attached objects such as a sink, a cabinet a TV, etc.

HEMPCRETE BENEFITS

One important benefit of using hempcrete is the sustainability factor. Making concrete results in very high CO2 emissions and its production is the third ranking producer of man-made CO2 in the world. Cement is the source of about 8% of the world’s carbon dioxide (CO2) emissions,according to think tank Chatham House.

Hempcrete and Hempcrete blocks are a CO2 negative resource. Using it actually lowers our CO2 emissions. Hemp absorbs CO2 from the atmosphere as it grows, retaining the carbon and releasing the oxygen. This process is called carbon sequestration. In fact more carbon is taken out of the atmosphere by the growth of the hemp plant than is emitted as a result of its production.

Hempro isohemp system

Thanks to the Hempro Isohemp System you can now build an entire building using only one natural insulating material: hempcrete blocks. For a homogenous construction that benefits from all the hemp qualities. The Hempro IsoHemp construction system is a simple, fast, economical, customisable and reliable solution. It meets all your expectancies of modern housing with great opportunities. From a single-family home to a building fit for an eco-district, you can easily implement low-energy, very low-energy or passive constructions.

There are many advantages to the Hempro Isohemp System with reinforced concrete.

  • Homogenous wall
  • Customised construction: The Hempro System tackles many technical challenges and lets you implement any sort of project.
  • Time-saver at the building site  : working with only one insulating material that is large and does not weigh much and is quickly fitted. Interior and exterior finishing options can be directly applied to the masonry. 
  • Large room sizes for extra living space and large picture windows.
  • Easy to construct: The base frame inserts into the insulation without a temporary frame.
  • Healthy and natural product.

The resulting load-bearing structure are: modern, economical and very cosy buildings! 

HEMPCRETE INSULATION

From Farmhouses & Barns to Victorian Dwellings.

Building a second, exterior wall of your home is the optimal solution to achieve high thermal insulation for the entire building, while still having all the finishing options for your facade! Whatever your exterior insulation project might be, hempcrete blocks are a perfect choice.

Benefits of exterior insulation

  • Avoid thermal breaks.
  • Keep thermal mass inside.
  • Improve the look of the facade.
  • Easy to fit.
  • Protect the inside of your home.

High performance thermal insulation

In winter as in summer, you want to maintain a constant and pleasant temperature inside your building. The hempcrete block lets you achieve this by naturally regulating the temperature of your house thanks to its capacity to diffuse accumulated heat. Its great inertia helps protect from cold in winter and hot in summer.

Why choose IsoHemp hempcrete blocks for exterior insulation ?

They offer a complete durable insulation for buildings and allow many different finishes. The blocks are laid on masonry & peripheral foundation. That way they provide support for a quality aesthetic finish.

HEMPCRETE Floors

The use of hempcrete blocks on the ground enables you to insulate the tiles and is a suitable base for screed. Whether it’s a renovation or a new build, insulating your floor has never been such a fast task thanks to IsoHemp hempcrete blocks. This technical solution is fast and simple. The product is dry, which makes it possible to add the finish of your choice very quickly.

The advantages of hempcrete blocks to insulate floors.

Excellent compressive strength (15t/m2).

Fast installation and efficiency over time that appeal to many architects/designers.

High technical flexibility like the option of underfloor heating, insertion of ducts in the screed.

Laying insulation for an entire building: in just a few hours simply lay the blocks on the ground staggered and then add a layer of reinforced screed.

HEMPCRETE ON FLAT ROOFS

If you want to insulate a flat concrete roof, it’s easy to use hempcrete blocks. Whatever the configuration, their installation is fast and easy. A slope layer of concrete is applied on which the sealant for the roof will then be applied.

This solution has the advantage of a quick and easy on-site implementation.
Equipped with a high thermal inertia, the hempcrete block makes it possible to stop the building overheating in summer and to guarantee an excellent insulation over time.

HEMPCRETE construction facts

Buildings made of hempcrete:

Store the carbon from a renewable biomass throughout the life of the building material. Create a vapour-permeable construction envelope that ensures healthy indoor air quality.

Provide excellent thermal insulation and a large thermal mass, depending on block size. Avoid thermal bridging and provides good airtightness with simple detailing.

Are simple to construct. Building with Hempcrete requires care but the skills are easy to learn and homes made of Hempcrete last for hundreds of years.
