This course will review an in-depth breakdown of permeability standards for both products and systems. The attendees will learn more about the multiple building products and how they perform in permeability standards. Discussion points to include the changes of the current energy codes and the requirements for the use of permeable and nonpermeable products. The participant will be able to better evaluate their current building assemblies and understand the requirements that are dictated by current codes.
- Identify the differences between Permeable and Nonpermeable materials.
- Review the differences between the 4 categories of permeable products and how they are rated.
- Recall the different testing methods used in rating different materials and assemblies.
- Discuss how vapor drive works along with proper specification of building materials in different climates.
