Do Concrete Masonry Walls Require Continuous Insulation?
Revised 2023 No. This is a common misconception. Although one particular compliance path (2021 IECC Table C402.1.3) requires insulation to…
R-Value/U-Factor Calculator
The CMHA R-Value/U-Factor Calculator is a spreadsheet-based calculator tool that determines steady state thermal properties of concrete masonry assemblies. Calculations…
Thermal Catalog of Concrete Masonry Assemblies
Revised 2012 Energy codes continue to evolve and requirements for building envelopes continue to tighten. Fortunately, concrete masonry construction provides…
Will Doubling a Wall’s R-Value Double the Energy Efficiency?
Revised 2014 Rarely. Although higher R-Values reduce heat flow through building elements, the R-Values have a diminishing impact on the…
What Options Are Available for Complying With the International Energy Conservation Code?
Revised 2024 The International Energy Conservation Code (IECC) [1] provides several different, independent methods of complying with the minimum energy…
How Can Concrete Masonry Assemblies Comply With Code- Mandated Air Barrier Requirements?
Revised 2024 The International Energy Conservation Code [1] includes performance requirements for air barrier materials and systems. In the 2021…
Can “Equivalent R-Value” be Used to Determine Compliance With Mass Wall Energy Code Requirements?
Revised 2014 No. The Equivalent R-Value of concrete masonry assemblies (or any mass wall system) cannot be used to determine…
Concrete Masonry in the 2012 Edition of the IECC
INTRODUCTION Although masonry is an ancient material, today’s concrete masonry can be a significant benefit to modern sustainable buildings. In…
Heat Capacity (HC) Values for Concrete Masonry Walls
INTRODUCTION Heat capacity is a material property used to assess a wall’s thermal mass, and it is often used as…
