Concrete masonry homes are less expensive to heat and cool than insulated wood frame homes in mild climate zones. Some of this energy efficiency is attributed to the mass of a concrete wall. A concrete wall takes advantage of differences in night and day temperatures 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 compared to only 1 hour for an insulated wood frame wall. For example, a masonry wall with R-4 added insulation is equivalent to an R-13 frame wall in climate zone 1.
Fi-Foil has innovative solutions for masonry walls that augment the mass of masonry by adding layers of highly reflective material that significantly decrease the transfer of heat through radiation and reduce convection in the building wall assembly. In addition, we offer solutions that are paperless to decrease mold growth and comply with green building standards.
