Hemp construction techniques for hemp insulation using spray, block and cast-in-place will be discussed by international and U.S. experts in Denver at the NoCo8 Hemp Expo in March, organizers announced. 

Construction experts will share their expertise about hemp-lime “hempcrete” insulation in residential and commercial building projects at the Crowne Plaza Convention Center in Denver on March 24-25. 

Fire-resistant, mold and pest-proof, hempcrete is gaining popularity in the United States after being used in Europe for 30 years to build carbon-negative natural wall assemblies.

Expert panelists will speak at the Education stage on the Expo’s Trade Show floor  at 2 p.m. on Thursday, March 24 during the NoCo Hemp Expo’s Business Conference and Investment Summit.  

Hemp construction panelist Cameron McIntosh, founder of Allentown, PA- based Americhanvre Cast Hemp is likely the most experienced spray-applied hemp insulation subcontractors working in the United States. 

Americhanvre also sells equipment and supplies. The company announced the April rollout of an American-made model of the EREASY Spray Applied Hempcrete System, developed in France. The machines will by manufactured by EZG Manufacturing in Malta, Ohio.

The spray-applied wall application of hempcrete insulation can result in 60% faster installation and reduced cure time for hemp-based buildings, McIntosh said. 

Construction panelist Ray Kaderli of Hemp Build Network is a Texas-based production builder and real estate investor who is insulating hempcrete homes in San Antonio, where a crew of hand-casting hempcrete builders recently completed a small hempcrete cannabis juicery.
