With the walls its Plan B

As my friend Guy remarked "there is margin in mystique". 

The steel framing method where a mobile factory and arrives on site and extrudes all the sections in a day may be the best way to go overseas but locally the contractors are killing the market with ridiculous pricing.








So plan be is to build a cavity brick wall with a 50mm cavity and pour the insulation into the cavity as the building goes up. The product (Thermopour) comes in 100 litre bags and is mixed like cement.
