Rationale

Hempcrete is an eco-friendly construction material that can be made into an insulation material. The process for manufacturing hempcrete varies from region to region making it difficult, if not impossible, to create a specification for the composition of this material. Therefore, a performance specification is necessary to qualify the insulative properties of a hempcrete insulation material. Performance specifications will allow for hempcrete manufacturers to produce hempcrete in any way they see fit using any number of aggregates or binders, and make it easier for hemp-building projects to get permitted and pass inspection, so long as the hempcrete meets the insulation performance specification. This working group will generate the unbiased data necessary to establish the average R-value and Fire Resistance of hempcrete insulation that shall be used as the foundation for a hempcrete insulation performance specification.
