Masonry Wall Insulation

Concrete masonry homes are less expensive to heat and cool than insulated wood frame homes. Much of this energy efficiency is attributed to the mass of a concrete wall. In Florida, a concrete wall takes advantage of differences in night and day temperature by responding to changes very slowly. As a result, less energy is required to maintain a comfortable constant temperature inside your home. It may take 4 to 8 hours for a temperature change to migrate through the mass of an insulated concrete block wall and only about 1 hour for an insulated wood frame wall. For example, a wood frame construction in Tampa, FL must have three times the R-Value than is required for a masonry home.

Masonry Walls have built-in insulation

  • Reduce heat gain and loss with mass
  • Small portion of overall load - 7% (see pie chart)
  • Masonry Wall with an R-4 added insulation is equivalent to an R-13 frame wall
  • Invested energy dollars are better spent on higher load areas in the structure such as roof systems, windows, infiltration, and mechanical systems
