They can be used in conjunction with foundation panels and stacked to create multiple stories as a part of a complete wall system building solution.

Basement walls made out of concrete stone concrete bloc and other masonry foundation materials have very minimal insulating properties and cause approximately 20 of heat loss in a home.
