There is a harsh environmental reality that globally, most homes are built with zero insulation. The most common building type on the planet is concrete frame with brick or concrete block infill walls. It's estimated that 99% of these homes are completely uninsulated.

I've lived in a poor place and built several homes there. I know how concrete frame homes work, and also the types of building materials that are available. If one wants to install continuous exterior insulation, rigid foam board would be your best option, but it doesn't work well, with thermal bridging and thermal bypass limiting the effectiveness of the material. And rigid foam board is relatively expensive and unavailable in many places.

I've been working to develop solutions to this problem, using monolithic pour lightweight insulating concrete (LWIC). It's an imperfect solution in a lot of ways but could be effective and create a safer and healthier living environment for a lot of people.…
