Instructor: Christopher Hine (Residential Design & Construction Specialist, PHRC)

Rooms located above a garage, often referred to as bonus rooms, have been a source for difficult air sealing and thermal control details. In this session, learn about these locations and review details on how we can reduce the risk for air infiltration and thermal control details.

Learning Objectives

  1. Understand the initial concerns regarding bonus rooms and their relationship to surrounding conditioned and unconditioned spaces.
  2. Review bonus room air sealing details that could allow for both unconditioned air along with potentially hazardous air to enter the conditioned space above.
  3. Discuss details and materials used in creating the assembly between bonus room and the space below. This assembly is critical as the control layer that can keep poor air quality from entering the conditioned space.
  4. Examine how the 2018 IRC requires specific materials to be used between the garage and bonus rooms above for the safety of the occupants.
