Hemp Building Materials

Sharing is caring!

Hemp can replace synthetic, petroleum-based and other high embodied energy materials to produce high-performance products that are better for the environment, better for your health and your wallet.

How Hemp is Used in Building Construction Materials

The parts of the hemp plant currently used for construction are woody inner core (for hempcrete), the outer fibrous skin (for hemp fiber batt insulation) and hemp seed oil (for hemp oil wood finish and deck stain).

Hemp-Lime “Hempcrete” Building Envelope Thermal Walls

Hemp shiv or hurd is mixed with a lime-based binder to produce a rigid material that is cast into walls, between or around structural supports. Hempcrete walls, When cured and finished, exhibit low toxicity and good vapor permeability while maintaining a high degree of airtightness,  good thermal insulation, and stabilizing thermal mass. This combination of properties, unique to hempcrete, combines to create a sustainable, healthy and comfortable indoor environment.

Hemp Fiber “Batt” Insulation

Hemp fiber is bonded into sheets that be formed and cut into a variety of dimensions then installed as semi-rigid “batts” between structural framing as a direct substitute to fiberglass and many other typical insulation materials. Hemp fiber insulation exhibits higher insulation performance (R-Value) but less other beneficial characteristics than Hempcrete in its typical application.

Hemp Oil Wood Finish and Deck Stain

Hemp oil is pressed from seeds and processed to produce a coating that is easy to use, beautiful and durable. Product test results show that hemp oil based deck stain can outperform high-end commercial products in resistance to weathering while containing very low levels of toxic VOCs (volatile organic compounds), making it an excellent alternative to synthetic and petroleum-based polymer coatings.
