Nov 14, 2025 · Learn the baseline thermal resistance of cinder block walls and discover practical strategies for significant insulation improvement.

Perlite and perlite insulation values for masonry units outlined and described including coverage charts.

Jan 31, 2022 · The R-value, or thermal resistance, of a cinder block wall ranges between 1.9 and 2.5. This is not suitable for an exterior wall which should range in value between R-13 and R-23.

Concrete masonry’s thermal performance depends on both its steady state thermal characteristics (described by R-value or U-factor) as well as its thermal mass (heat capacity) characteristics.

The R value of cinder blocks is an important measure of how well they resist heat and help save energy in construction. Knowing what affects this value can help you make smart choices …

Understanding the r value of cinder block wall is crucial for managing energy costs. A higher R-value means less heat is lost in the winter and less heat is gained in the summer, reducing the …

R-value is the measure of insulation to gain or lose heat. Learn which materials create a higher CMU (or concrete block) R-value, including cellulose, denim batts, and silica aerogel.

Jan 15, 2025 · The R-value of cinder block insulation falls between R-1.9 and R-2.5, depending on density. While cinder blocks provide structural strength, they do not insulate well on their own.
