Mass Masonry Walls and IECC Compliance

Provider: Mason Contractors Association of America
Discipline: Codes & Standards
Credits: 1.00

This webinar will address energy code compliance options for masonry walls. With respect to new construction, the various compliance paths will be explained, including a review for the mandatory versus prescriptive requirements. The U-factor alternative and continuous insulation requirements will be clarified. Additionally, the seminar will address retrofits of existing mass masonry walls, which require additional considerations with respect to the durability of the existing materials, especially when insulation and air barrier are installed on the interior of the walls. The need to evaluate masonry assemblies of existing buildings prior to modification is more essential than ever to ensure the benefits of changing the thermal and vapor resistance properties are not outweighed by the risks. A new standard, ASTM E 3069, “Standard Guide for Evaluation and Rehabilitation of Mass Masonry Walls for Changes to the Thermal and Moisture Properties of the Wall,” addresses these considerations for retrofits.

The webinar will discuss the application of the standard and the need for such guidelines based on the changes to the energy codes and offer resources that will improve the overall energy performance of existing mass masonry walls.

Learning Objectives:

1. Understand the various compliance paths with respect to energy codes and masonry construction, including the differences between mandatory vs prescriptive requirements and minimum insulation versus U-factor alternative.
2. Understand special concerns and red flags when adding insulation or air barriers to existing masonry construction.
3. Review the procedures and goals of ASTM E 3069 “Standard Guide for Evaluation and Rehabilitation of Mass Masonry Walls for Changes to the Thermal and Moisture Properties of the Wall.”
