Hemp can be turned into Building Products creating a circular economy. Hemp grown by Missouri Farmers to create sustainable and energy efficient structures for Missourians is the ultimate in Green Building for a local economy.

Hemp Fiber Insulation, Hemp Plaster, and Hempcrete could be used by Missouri Craftsmen to build Energy Efficient Sustainable Missouri Homes- This is the Ultimate in Buying Local!

I’m from a farming/ranching background and now in the design build construction business.  I’ve been following how the Hemp plant fibers can be utilized to build highly energy efficient homes when they are mixed a couple of natural products- Scotty

One of the products I’ve been following is called hempcrete.  It has the strength of concrete and is also energy efficient, removes and traps carbon from the air as it ages.  This to me is the ultimate in sustainability for future Missouri Homes and Buildings.  

I’ve also been researching how:
-hemp seeds can be turned into a form of oil and can be used as a biodiesel product for the transportation industry.  

I’ve also seen a video by Henry Ford that showed he used the fibers from a plant to make early auto parts that were strong enough to take a blow from a hammer without damage.  

I’d like to see the State of Missouri Leading on the use of the industrial hemp plant-instead of falling behind other states and countries where it is working to create Sustainable Economies.  Scotty

In my quest to promote affordable sustainable buildings for the St Louis region has lead me to discover a new building product that provides high Rvalue for energy efficiency and has the strength of concrete!

I appreciate all the medicinal applications of Cannabis but what really turns my crank is the uses of the Industrial Cannabis or Industrial Hemp products: Food, Fuel, Building Products, etc. 

 I've been focusing my efforts on the Hemp + Lime mixture that some people call #Hempcrete  used in making buildings energy efficient naturally.

And when I learned that this revolutionary building product could be locally grown I believe I stumbled upon a viable solution that exceeds the needs of the growing Sustainable Driven Community.

This is the Ultimate in Buying Local!
One of the issues I’ve found while working on the brick buildings in the StLouis Region is the challenge of having adequate insulation on the exterior walls of the Masonry Structures.

These CAD designs by Scotty is one of the latest designs reflecting how this insulation could be installed over a Grid of #4 structural reinforcement.

Hempcrete Wall RValues
4 Inch Layer of Hempcrete = R14.2
Multiwythe St Louis Brick Building= R5
Total Wall RValue=19.2

Stay Tuned for more information.  I will soon be posting information from a Sustainable Builder who has been involved in the Hemp Building Industry in Europe.

Mr Greg Flavall,  has given these suggestions:
Depending on age of buildings u can ascertain whether lime mortar was used or cement. Older buildings used lime in which case u could add hemp/lime “plaster ” to exterior or interior to increase efficiency as we have done many times in Europe. If cement forget it; you’re asking for problems.

In UK we have had problems in the early days adding hempcrete to cement mortared brick clad buildings bc they do not breathe and the hemp has deteriorated;…

Also u can use an alkali resistant mesh cloth embedded into the Hempcrete for added flexural strength and no need for steel reinforcing unless you are horizontally affixing steel plates to retain brick structure

Mr G. Flavall, Hemp Technologies;

shares these Hempcrete Characteristics on their website:

  • Thermal Mass Insulation
  • Negative Carbon
  • Low Density
  • Clean Air
  • High Thermal Resistance
  • High Thermal Inertia
  • Vapour Permeable (breathable)
  • Design Flexibility (adjustable thickness)
  • Fire and Pest Resistant (NO Termites)
  • Significantly Reduce Co2
  • Emissions
  • Inherently Airtight
  • No Waste
  • No Mould
  • No Termites
  • No Dry Rot
  • Natural Substrates for Plasters and Renders
  • Low Air Infiltration

Here is a CAD design of my Future Hemp Home
