Concrete and concrete block walls can be insulated in a number of ways.
Concrete block can be insulated by applying rigid foam board to either the outside of the walls (on new construction) or the interior walls (on existing homes).
An additional method of insulating concrete blocks involves the use of blocks consisting of autoclaved aerated concrete (AAC) or autoclaved cellular concrete (ACC). These materials contain about 80 percent air by volume and have about 10 times the insulating value of traditional concrete blocks. Precast ACC blocks use fly ash instead of the high-silica sand used in AAC blocks. Autoclaved blocks easily absorb moisture, so they must be protected from water, but they are lightweight and easy to install.
In poured concrete foundations, beads of polystyrene foam can also be incorporated into the concrete mix to increase their R-value. This method can increase the R-value 10-fold over standard poured concrete.
