Looking for a weight comparison air/hemp/dust/styro crete to conventional wall system

Hey there,

Looking for a weight comparison air/hemp/dust/styro crete to conventional wall system.  My mind runs to things like this.  I'm curious about how the load compares across the 'cretes' and ultimately to a conventional wall system.  Our house now has typical 2x framing, board, plaster, and fibreglass insulation.  I'm wondering if panelised 'crete' products would be lighter (or heavier or comparable) on a frame.  

Anyone know?  Or know of a calculation?

Thanks heaps,

Hi Nissa,
I would guess that someone somewhere has done the math, but it was not me :)

The best I have is to tell you that hempcrete is generally 1/8th or 1/7th the weight of concrete. In all the use cases of hempcrete that I have seen, it is not being held up by the frame, it is being held up by the foundation, and simply surrounds the frame.

You simply need to find the density of each product, then do the maths to determine the volume of each material used.
Some may need a thicker wall to be used in a practical sense.
