- Hempcrete is a bio-composite material created from the woody core of the hemp plant combined with a lime-based binder. Trusted around the world as a robust, high-performance sustainable building system, HempLime entered the US market a decade ago and is poised to take the industry by storm. Learn the technical and performance characteristics, demystify how to specify and construct with this proven material, and join a growing community of radically responsible industry stewards.
this wasn’t the 1st .. (or 2nd) time i’ve watched Alex Sparrow presentations.....and i must say that this one was pretty good, namely due to the Questions & themes raised after the presentations.
so thank you all ,
hope you’ll make part 2 available here on YT.
cheers from Portugal
Very informative presentation! Thank you. Looking forward to more like this.
incredible talk. sparrow knows his hemp. thanks!
Very interesting hempcrete topic.
Massive amounts of rice husks are available in Arkansas as they par boil to remove the husks.. Arkansas seems to be well available
What a comment. Dumb
@@Nestavan The point is there are other plant based insulators. and this is not a dumb comment just a note that while it does not have all of the properties of shiv it does have a large amount of silicon in the husks that just dont break down
@@stevepailet8258 if you want to compare a plant insulation which DOES NOT BURN, resistant to Mold and mildew and pests, including flood damage, by all means
I’m pretty sure the lime makes it
Pest resistant and not the hemp, just saying
@@ronkelley1115 correct that said hemp is also very high in silicon which has a similar effect
Greetings, fellow hemp enthusiasts. Check upon our hemp-related page and content. Be blessed all!
What are options for vapor permeable air tightness layer?
Does hempcrete block cell phone signals and wireless internet?
How I can do if I want to install wood cladding outside but also inside please ?
Thanks a lot for the video
1. Is hydraulic lime the best type to use for walls?
2. Is it safe to build two story house with 2x6 boards and hempcrete?
Was curious about hemp as a monolithic infill does that allow not needing inset cross bracing in the wood assembly.

Thank you all, very informative. I have a question regarding timber frame. Are there any issues with the spruce timber frame warping due to moisture transferring through the wall? Some builders in Hungary claim there is an issue and either use hard wood which is prohibitively expensive or what they call HTS structure.
As much as moisture might transfer through the wall to the frame it will also transfer through the wall and away from the frame. So the short answer is no on the warping and any frame (softwood or hardwood) will move depending on how green/dried upon installation, how much moisture loading there is inside the spaces (cooking, hot tubs, large dogs) and how spaces are heated ( traditional vs wood stoves). I have an unrendered (unplastered) hempcrete wall that has been sitting outside for three years on a piece of regular (non pressure treated) plywood. This wall gets rain, snow plowed up against it… and the plywood looks like the day it was built because the hempcrete continually wicks moisture away and stabilizes the plywood as well as the exposed end frame. Repeated moisture testing verifies this stabilization.
@@tomrossmassler8213 What about the moisture that go inside of wall, during the under zero temperature... is there a risk please ?
Thanks a lot for your answers
What are your thoughts on hempcrete walls with a parapet? I've heard of using a fiber board for the parapet, then plaster seamlessly
Any plaster meeting a differing substrate should be properly taped and/or flashed. Most of the products available to the US stucco industry or high performance green building industry are not appropriate. Sourcing the right materials is key 475 supply, rothoblass, etc…
Can hempcrete be used to fill cold formed steel partition walls?
Can prompt cement be used instead of lime to avoid corrosion?
Hello, I am going to be helping with a hempcrete house in Montana, can you help me with any contacts for experienced hempcrete builders in my neck of the woods?
