Everyone thinks it must have been the sustainability factor, the sensationalism of hemp or even, our namesake- non-toxic, healthy homes. Since hempcrete appears lightweight, some people are concerned about its durability. Another famous illustration are the hemp panels of the British Science Museum that are used in an artifact storage unit because the material provides superior control of the environment.

This material does well in relative humidity above 90%, and it can hold the water vapor without degrading. The lime binder used in making hempcrete also has antimicrobial and antifungal properties that keep the coated surfaces of walls resistant to mold. The property is at 8,000 feet elevation surrounded by mountains on every side. The area is high plains desert so there are many piñon pines, rocky sandy ground and sage. The thermal performance coupled with the south facing windows and thermal mass will be extremely effective in the colder winter months.
The Science Behind Building With Hempcrete
Because this building sector is still in its nascent phase, no one actually knows what could happen if the demand for hemp houses would rise. But on Monday, the full Senate advanced the ban 27-9 without any debate. In what would be his opening and closing statements on the bill, he referenced the laws the legislature passed that created the consumable hemp industry in the state and updated requirements in recent years.

The insulating quality is r-2.5 per inch, and it has the unique ability to capture airborne pollutants over time -- it absorbs carbon when it is grown and in place. The material's high thermal mass helps keep a steady interior temperature as well. The interior walls are made from Purepanel, another unique product that is made from recycled paper. It consists of a rigid skin with a corrugated paper core, just like cardboard. The project also features 30 window frames that have been salvaged and fitted with high tech glass. They were placed to get the most daylighting without overheating the space.

The Controlled Substances Act of 1970 classified both hemp and marijuana as Schedule I substances, hindering their cultivation and its use. Recent years, though, have witnessed a resurgence of interest in hemp as a versatile and sustainable crop and legislative changes to distinguish it from marijuana. In the U.S., before being stigmatized and criminalized in the 20th century, cannabis had a long history of use for various purposes. In 1619, responding to England’s growing need for maritime ropes, Jamestown colonists cultivated hemp in the New World, as the Queen of England mandated. However, the Marijuana Tax Act of 1937 marked the beginning of its prohibition, eventually leading to its classification as a Schedule I controlled substance in the 1970s. The subsequent decades saw a shift in public perception, with increasing acceptance of cannabis for both medicinal and recreational use, culminating in the legalization movement that swept across various states in the 21st century.
The inspiration for creating a hemp-based home came when the couple was still living in Los Angeles.
All three projects began, or were completed, in 2022 and the builders/subcontractors are already starting new projects. This is because it isn’t suitable for load-bearing walls, and the foundation structure has to be made out of timber and steel. A house made of hemp might sound like a hippie idea from the 70ies, but is actually a concept that can build our sustainable future.
Hemp Houses: A More Sustainable Way to Build and a Healthier Way to Live
This expense, multiplied across team members, adds up significantly for small businesses and entrepreneurs in the hemp industry. A Santa Barbara County official said a project has been submitted for planning approval but still needs to pass most stages of the permitting process. A house, outbuilding or any other structure would have to be deemed appropriate for the site, and any unconventional materials would have to be declared safe. In addition, hempcrete is a much better insulator than traditional concrete, though how much better depends on the moisture content and the density of the material.
We are doing the garage of a house we will build next year in La Veta, CO. We’re also building an office inside of Global Fiber Processing’s new facility and making blocks at our facility in Lafayette, CO. As for building projects, we have three in the books and several down the pipeline. Two in Wimberly and another in Pipe Creek is being zoned, mapped and prepped for rainwater harvesting, earthworks and permaculture while we are in the design phase. In that spirit, we’d like to introduce you to three new hempcrete builds in Texas, Colorado and Michigan.
The internal walls have been left as exposed hemp, featuring cross sections of marri tree limbs. Take a Deep dive into specification and installation of Hempcrete and Natural Plaster wall systems throughout the building envelope. Recommended as an all-in-one introduction for industry professionals and self-builders. But now, the company is taking unlimited pre-orders for the spring 2022 season. It's already seen hundreds of inquiries, including some that want to create entire communities out of Travelers.
In addition, hempcrete is known to be resistant to pests, mold, and insects. One cubic meter of hempcrete wall can hold up to 30 kilograms of carbon. The House passed House Bill 952 by Rep. Dustin Miller, an Opelousas Democrat, that would keep consumable hemp products legal, but tighten regulations on them. "If anyone is exploring the idea of using an alternative building product they should definitely look into it [hemp]," she said. Ms Jankowski said the total cost of the build was about $300,000, which put it in the ballpark of conventional building products like double brick.
An open floor plan helps the light penetrate deep into the home as well. To maintain breathability, we use historic lime plasters on the exterior so moisture is always released keeping away mold and rot. In contrast, hemp houses are often described as breathable structures that provide natural sound and thermal insulation, humidity regulation, and effective protection from the elements.
This fully built cabin is sure to be the perfect space to feel good and get comfortable, whether as a Airbnb, a mother-in-law suite, or even temporary housing. This particular design, paired with small windows both helps the energy efficiency of the home and brings occupants out of the building so they spend more time connected with outdoor spaces. The hemp industry has emerged as a promising agricultural industry in recent years, offering economic opportunities and sustainable products. However, one significant hurdle faced by hemp producers is the requirement of fingerprinting and extensive background checks, which can be costly, time-consuming, and arguably unnecessary. Hempcrete blocks can maintain interior temperatures, among other uses, and are made of the plant's woody core, a limestone-based binder, and water.
They're also biodegradable, lightweight, and have no carbon footprint, according to Coexist. Hemp can also be used like stucco to protect the outside walls of new and existing homes from moisture. As a vapor-permeable material, it can absorb water when it’s raining and then expel it when the sun is shining.
To compare, concrete has an R- value of 0.1 to 0.2 per inch, making it an insufficient insulator. It would have cost even less if Velasco had been able to source the hemp hurd and lime locally, he said. Velasco trucked in American-grown hemp hurd from North Carolina and imported lime binder from Europe for the project. A movement to create low-cost mini-housing in the state of California may be the golden opportunity hemp building needs to enter the public consciousness, one builder and startup founder believes.
