Hempcrete's Fire Resistance

Exploring How This Plant Could Replace Concrete

Building with Hemp fire test on hempcrete

 

Please note, this video below doesn't feature hempcrete, but it shows why, in my opinion, spray foam should be OUTLAWED in new construction in California. When it burns, it turns into an INFERNO. It releases so many toxins into the air and ground, and those toxins will eventually get into our water supply! It seems like there isn't a single area in this state, that isn't at risk for a serious fire, due to climate change. Look at how flammable the spray foam is! Again, this is just my opinion but it really seems like this is the VERY LAST thing we should be using in houses. Especially when we have such a cheap, fire-resistant, non-toxic, termite-resistant, highly insulative, carbon-sequestering, healthy building material like hempcrete!

How fire resistant is Hempcrete

Please note, I think it's much safer to put hempcrete (rather than hemp batting) into walls, because although the video below shows that the hemp fibers don't burn, I did see a different video that shows they can burn somewhat, without a lime binder (that's found in hempcrete). I'll post that video (by Belinda Carr) below this one.

AI Overview

To provide significant fire protection, hempcrete walls should typically be around 300mm (12 inches) thick. This thickness has been shown to offer good fire resistance in tests, with some studies demonstrating that hempcrete walls can withstand direct flame exposure for extended periods without significant damage.

Key points about hempcrete and fire resistance:
Thermal mass:
Hempcrete's high thermal mass helps to absorb heat slowly during a fire, delaying the spread of flames.

Non-toxic fumes:
Unlike some synthetic materials, hempcrete does not release harmful fumes when burning.

Building codes:
Check local building codes for specific requirements regarding hempcrete thickness for fire protection.

I found this video about how Jennifer Aniston protected her home from the LA fires. This is awesome that she was able to afford to do this! But who else can afford this kind of fire protection?
