HempWool® insulation is a sustainable and natural insulation material made from a blend of hemp fibers and recycled textiles. It offers excellent thermal and acoustic properties while being safe, non-toxic, and environmentally friendly.
It is an easy to use product substitution for conventional insulation products like fiberglass or mineral wool. You can learn more here.
Ordering HempWool insulation is easy.
Check out Buy.Hempitecture.com or simply browse our Shop on our website and add the desired size and quantities (in sq.ft.) to your cart from there you can choose to have the materials delivered or you can arrange getting the materials yourselves and one of distribution hubs. Follow the checkout process, providing the necessary shipping and billing information, and complete your purchase. For any assistance or special requests, feel free to contact our sales team at sales@hempitecture.com or give us a ring at (208) 218-8698.
HempWool® is made up of approximately 92% hemp fiber and 8% textile fiber binder.
The R Value of HempWool® is 3.69 per inch.
HempWool® be used in flooring, ceilings, walls, or anywhere else traditional insulation is used. HempWool® can also be used in vans, trucks, or bus building projects.
There are a number of tools you can use to cut HempWool. A non-serated blade is best. This could be a manual insulation knife used for cutting RockWool. Additional tools include a metal cut off wheel on a handheld grinder, a FESTOOL insulation saw, or even an electric bread knife.
HempWool® can be installed by any local insulation subcontractor, general laborer, or even yourself!
It’s easy and safe to use!

In addition to finding the total square feet of the wall(s) is by multiplying ceiling height by total wall length.
HempWool is a 1-to-1 replacement for conventional insulation products. Therefore, it works in conventional situations with 16″ OC or 24″ OC framing layouts.
HempWool works well under drywall, but can be used in conjunction with nearly every standard building material.
HempWool® has Class-E fire resistance, so although it is seen as higher on the FSI and SDI, you can protect HempWool between fire-resistant walling (both your exterior siding and interior wallboards). Due to the lack of fire resistance, it is generally approved by a case-by-case project and is not applicable for some projects.
HempWool is Vapor Permeable and Hygroscopic – meaning it can interact with moisture without any problems. HempWool helps prevent airborne moisture movement, improving building durability and longevity. HempWool disperses moisture and helps to protect the surrounding building components. It has the ability to store and release moisture without loss of its insulating properties. In fact, we’re currently doing a study on its mold resistance, since it is a great characteristic of the product. It’s not complete yet though.
ASTM Standards testing shows no mold growth. If HempWool is exposed to excessive moisture such as a flood or a persistant leak, like any product, mold can grow.
Hemp Fiber naturally repels rodents, mites, and termites because of the silica (a mineral) in the hemp plant. Hemp also has very little protein for pests and the mechanical strength of this material is too strong for anything to nest in it.
HempWool performs comparably to conventional insulation products in regards to sound attenuation. In the future, we intend to launch acoustic insulation products.
HempWool is ideal for humid environments, since the hygrometric insulation is vapor permeable and also resistant to mold. HempWool should not be exposed to excessive moisture, as excessive moisture can cause mold. Interior to a cavity that is properly air and vapor sealed, HempWool is the ideal product for humid climates.
HempWool insulation is extremely safe to handle and install. It contains no formaldehyde, glass fibers, asbestos, Chlorofluorocarbons (CFCs), Hydrofluorocarbons (HFC), or Hydrochlorofluorocarbons (HCFCs). There are no health risks such as cancer-related warnings associated with its installation. It does not irritate skin or itch as does mineral wool and fiberglass insulation.
Our products have been approved for use by building departments across the country. Because HempWool® and hempcrete are new to the construction industry, a technical conversation is useful for most building offices and inspectors to become familiar with these materials but they are often supportive of their use once they realize the sustainability potential. It is usually up to the local building jurisdiction to decide whether or not these building materials can be permitted.
Our products are currently manufactured in Canada. We are currently building a US manufacturing facility in Jerome, Idaho.
Plant based products generally are more sustainable than petrochemical, synthetic, or resource extracted products. This is because plants grow quickly, and during their growth cycle, the offset and store carbon dioxide. Industrial hemp is particularly adept at this.
HempWool is currently ASTM tested for a number of criteria. With our US manufacturing facility, we intend to have our products tested and qualified for numerous certifications.
Hemp and Marijuana both derive from the cannabis Sativa family, they do share certain similarities. However, due to each plant’s biological structure, they have several and very distinct differences.
Hemp plants are slim and very tall, reaching a height between 10 and 18 ft. Hemp leaves are also very skinny and are commonly found nearer the top of the stalk alongside the trichome-rich buds. Hemp plant color varies. Some are a lighter green, while others have a greyish hue.
Historically, industrial hemp and its fibers have been used for clothes, rope, shoes, carpets, and paper. Our products are 100% THC free.

The r-value of hempcrete ranges from r2.2 per inch to r2.5 per inch, dependent on density. this relatively low thermal resistance compared to other insulating materials do not take into account the thermal mass or phase shift regulating the capacity of Hempcrete.
In some instances, you can use Hempcrete for renovations. Hempcrete must be installed in a vapor open system. therefore, design considerations must be made to determine if Hempcrete is compatible with your renovation.
Cast-in-place Hempcrete is a mixed on-site, cast-on-site building method that uses temporary form boards to create the cavity in which Hempcrete is installed.Hempcrete blocks are pre-cured and delivered to the site in various dimensions. they are installed similarly to masonry-based blocks, but they are not structural or load-bearing.
Hempcrete is not intended to be a structural or load-bearing material. it cannot replace concrete. it is not intended for ground contact or below-grade applications.
Hempcrete should not be installed against osb or plywood. it is a vapor open wall assembly. consult a structural engineer for methods to gain shear value resistance without plywood or osb.
Consult our Hempbinder product guide to get an understanding of what equipment and tools are required for Hempcrete installation.

No. Hempcrete requires vapor open wall designs and should be finished with lime plaster or vented siding/cladding.
Hempcrete is an accepted building strategy for 1-story construction projects as referenced in the ICC Appendix. however, information should be presented to local code compliance officials to ensure its acceptance on a local level.
Hempcrete should be finished with vapor open materials or assemblies. lime plaster is recommended to be applied directly to the surface of a Hempcrete wall. alternatively, vented rain screen details or back vented siding could be applied on the exterior.

Hempitecture began in 2013 as part of a college senior thesis at Hobart & William Smith College by Hempitecture CEO Matthew Mead. In his evaluation of different natura building material solutions, Mattie decided hemp-based materials offered the greatest promise and trademarked and launched Hempitecture!
In 2018 after completing Idaho Basecamp and while working on the Highland Hemp House, Mattie reconnected with high school classmate Tommy Gibbons and the two founded Hempitecture as a public benefit corporation with a vision to scale sustainable building materials across the United States.
