Description
These 100% Made in USA hempcrete blocks are made with clean, graded, American hemp hurd and our proprietary hempcrete binder. We use a dedicated block making machine and our hemp blocks are cured in a temperature controlled environment. This is all done to provide consistent quality that you can count on.
Current sizing available for hemp blocks:
8″ (W) x 8″ (H) x 16″ (L) (Nominal)
12″ (W) x 8″ (H) x 16″ (L) (Nominal)
Hemp blocks and R-value/insulation numbers
The larger sized, 12″ hemp block allows for creating 12″ thick hempcrete walls. This gives even more insulative (R-value) benefit, keeping your home cooler in the summer and warmer in winter!
With an R-Value of 2 for every inch of hempcrete wall, an 8″ wall provides at least R-16 and 12″ offers R-24.
Those values are based on using a conventional hempcrete mix that contains only binder and hemp hurd. Adding aggregate (stones/sand) makes stronger, denser blocks but trades out R-value in return.
Notched/Retrofit Hemp Blocks for stud/timber framing
In addition to making solid hempcrete blocks, we also make hemp blocks that are notched to fit within a conventional stud framing system. For example, within a 16″ on center stud framing pattern as shown in the product gallery images. These hemp blocks fill the stud cavity and leave a flush surface on one side and 3+ inches of hempcrete mass on the other; allowing for multiple finish options based on your designs and wishes. In the images shown, 8x8x16″ hemp blocks were cast to fit against 2×4 studs but could also be made to accommodate 2×6, 2×4 framing and more.
The notches are set at the sides (type 1) or middle (type 2) of each block. This 2 block system allows you to create a staggered mortar joint going up the wall by using type 1 on the first course, type 2 on second and alternating up the wall.
Our notched hemp blocks simplify and speed up the building process for both new construction and retrofits. You could give an outdated home a high-performance upgrade, adding beauty and sustainability, making a true hemp home, by using these notched hemp blocks. Tear out the old painted drywall, fiberglass insulation, plastic wrap (materials often imported, highly synthetic with toxic or off-gassing concerns) and plastic siding, exposing the studs, and replace with hemp blocks and a beautiful, breathable finish such as lime/clay plaster and render.
