Does building a Hempcrete Wall take longer?

Most likely. As with any masonry-type construction, there are some limitations to the installation. For example, if the temperature gets too low, or there is excessive moisture in the air it slows the curing time of the lime-binder. The lime-binder can take anywhere from 4-8 weeks to completely cure. The sequence of trades and inspections […]

We have found that when presenting to code officials, it is important to emphasize the essential characteristic of the hempcrete – it is an insulation system with unique hygroscopic qualities. We have successfully permitted projects in seismic zone 2a, as well as in coastal regions with 130 mph wind loads. Establishing a relationship with the […]

Hemp has absolutely no use as a recreational drug. Think of the Cannabis Sativa grouping of plants as the Canine family, who’s genetic makeup has been altered to give way to breeds like […]

What is the R-value of Hempcrete?

The R-value varies with the density of the mix – the more binder, the less insulation. Additional binder increases the density of the material and hence its heat transmission properties. The mix that we typically specify has an R-value of about 2.4 For a 12” wall, yielding more than R-28 for the wall. There are […]

What are my finish options with hemp walls?

We recommend that the exterior be finished with an approved system like Baumit®. The interior may be finished with lime render, clay plaster, or lime-over-clay. Mineral colorants can be added to the render to provide a wide range of color options. Interior lime surfaces may have surface applied minerals mixed in a water solution and […]

Can Hempcrete be used in a basement?
