Not known for their high R-values, masonry materials are not thought of as good insulators. Masonry materials do, however, have thermal mass, the ability to store heat and release it later. As such, mass masonry wall systems have better energy performance than light-framed wall systems of equal thermal conductivity. This quality provides a great benefit by maintaining occupant comfort levels and lowering energy and equipment costs over the life of the building. Read more.
