PHRC Webinars

Durability of Insulated Rim Joists

10/11/2016 1:00 PM - 2:00 PM

Instructor: Chris Hine (PHRC)

Throughout the building enclosure there are various assemblies that are deemed critical to the long-term energy efficiency and durability of a building. When best practices are followed, these critical areas contribute to a sustainable enclosure. When one or more compo¬nents are incorrectly designed or installed, moisture accumulation, rot, or mold growth may arise. In this webinar we will look at the rim joist portion of the enclosure. Many scenarios come into play such as insulation materials, whether the basement is conditioned and what types of cladding or materials are applied to the exterior of the assembly. We will review these scenarios and work through the risks associated with them.

Learning Objectives

  1. Review areas of concern that can lead to degradation due to moisture intrusion.
  2. Review insulation materials that can achieve the required R-value along with having the potential to be left exposed in unconditioned basements
  3. Understand the long term deterioration concern of some assemblies. These assemblies can be hidden from sight and can pose a safety and health concern to the occupants
  4. Review best practices when insulation the rim joist assembly. This will cover many scenarios and will review the best assembly for each.
