Thickness of walls.
How do you know how thick you need to make the bricks? I am wanting good insulation and each inch makes a big difference.
It's your decision to make. Our experience is mostly in the tropics. You may want to research the use of AirCrete (celular concrete) in climates similar to yours.
Thanks, I'll do some additional research, with your experience in the tropics, how thick do you make the walls?
