Energy Efficiency = The Mass of Concrete Construction

Energy Efficiency = The Mass of Concrete Construction. Just looking at a piece of lumber and then a concrete masonry block makes it clear why concrete homes are more energy efficient than wood-frame homes. Concrete's mass slows down the passage of heat moving through the wall. This means that, with the same insulation, a concrete home stays
