Details

This webinar will provide an in-depth look at the cause and effects of below-slab moisture and vapor concerns in homes and considerations for incorporating effective, durable protection. With a science-based, educational approach, the presentation will provide a tailored look at the natural movement of water vapor, soil-gas (like radon) and subterranean termites into the first side of a home and the importance of taking the ground permanently out of play regardless of a home’s location or foundation type. Even more, the presentation will walk through the material innovations and evolving residential industry standards and guidelines that influence the selection and installation of foundation vapor control systems. This includes new requirements for the vapor retarder beneath concrete floors in the 2021 International Residential Code (IRC). There will be a particular focus on the role that effective vapor protection has on the long-term performance of homes, including energy efficiency, human health, durability, and reduced ownership costs/impacts – and the value it offers to homebuilding professionals and their customers. 

Learning Objectives:

  • Understand the science of below-slab moisture vapor, soil-gas, and subterranean termite movement into homes and potential negative outcomes related to home performance, human health, and overall sustainability.
  • Recognize the short and long-term problems with generic poly sheeting (or the omission of vapor protection) and be familiar with 2021 IRC requirements, as well as industry standards and guidelines for vapor retarders/barriers beneath concrete floor slabs and in crawl spaces of new homes.
  • Better understanding of the unique product performance and installation considerations for the barrier systems at the first side of the home given varying home foundation types and concerns.
  • Recognize why effective, durable foundation vapor protection aligns with consumer demands and offers homebuilders an opportunity to decrease liability and bring further value to clients.
