Live Investor Q&A

At Sativa Building Systems, our mission is to provide patented non-toxic Z-panels that ensure a safe environment for everyone!  Our Z-Panels consist of hempcrete, which is a combination of hemp shiv, hydrated lime, and water!

By creating products that differentiate from traditional wall construction, we are creating an entirely new kind of building process with materials that make safe homes for everyone. Because homes shouldn’t hurt people!

We recently held an exclusive investor Q&A webinar, where we had the opportunity to answer some burning questions from our investor community. 

Here are some of the most popular questions, but if you want to learn more, we suggest to watch the recording of the video!

How did you adjust hempcrete to make it a better material?

Zach Popp:

“Hempcrete in its original form is a satisfactory material. So it’s not so much that I made the material better, it’s that I put it into a more usable form.

The future of getting hempcrete commercialized and adopted in the market is in precast blocks or panels.

Hempcrete as the material is amazing, but as I mentioned, it does have those deficiencies where it takes a long time to dry out. 

We found a way, our unique process for drying the hempcrete ensures it doesn’t take six to eight weeks to dry. Instead, it takes about 48 hours at most.”

How does hempcrete reduce mold in a home? If it’s natural, wouldn’t it be susceptible to moisture and damage?

Zach Popp:

“Hemp is made from cellulose. Cellulose can mold and break down. I would never say that it’s impervious to mold. However, it’s more mold resistant because every little piece of hemp is coated in the lime binder. 

The binder is what makes it less susceptible to mold. Coupled with the fact that it’s breathable or vapor permeable, so it doesn’t trap moisture in the wall. 

So mold needs moisture to build up, right? Usually, if you were to spray your wall once with water and then it was to dry out, it’s not going to mold. But if you were to do that over and over and over, it’s why mold develops in places like bathrooms. 

Because there’s constant humidity, there’s constant moisture. Since hempcrete walls breathe, they don’t trap that moisture. They’re always releasing it. It’s the fact that it’s coated in a lime binder and breathable makes it much more mold resistant.”

Z Panel 2.0?

Zach Popp:

“Yeah. So Z Panel 2.0 in a nutshell is the lightweight version of the original Z panel. When I made the Z panel, I favored density to ensure that it had enough strength to stay intact and not crumble when you cut it. 

But after I made that version, I wasn’t super happy with the thermal efficiency of it. 

I thought I could get this higher. I knew that in all my research of other hempcrete products, they were able to have an R-value of closer to 22, 24, 25. Somewhere in that range for 12 inches of hempcrete, right? 

So I started playing around with different mix ratios and I adjusted the binder formula a little bit. Now I have a Z panel that uses less material making it more lightweight, has more air trapped inside that making it more insulative.

 Z Panel 2.0 is right around 45 pounds while the original version was closer to 60 pounds.”
