Hempcrete’s perfect performance in recent fire resistance tests in the USA can help move the material one step closer to acceptance after samples put together by U.S. hemp builder Hempitecture scored perfectly in analysis carried out by ASTM, the international standards organization.
Hempitecture announced the development in a post last week, urging other hemp builders to use the results in their efforts to convince permitting officials and regulators to look more favorably on hempcrete.
The holdup
Lack of testing “has been holding us back from truly being able to call hempcrete the fireproof material that it actually is, here in the U.S.,” Hempitecture said in the post. Results from the specific test, ASTM E 84-19B, are recognized by building code officials and regulators in their safety analyses of a range of building materials.
“We have faced the disadvantage of little to no U.S. based testing on the mechanical and performance properties of the material,” Hempitecture noted, adding that documentation from other countries has not proven sufficient in the U.S. building environment.
