MA - R3.1 Residential Air Barrier and Insulation Installation

Course Description: The installation of a continuous air and thermal barrier is perhaps the best and most cost-effective way to reduce energy waste and save money on utility bills; at the same time, important details are often missed. Part 1 of this course will be framed around the 2021 IECC Air Barrier and Insulation Installation criteria found in Table R402.4.1.1 with photos and graphics to illustrate noncompliant and compliant installation of critical details like attic penetrations, wall-to-ceiling transitions, rim joists, garage walls, knee walls, and tubs and showers on exterior walls. Installing and inspecting insulation to meet code and manufacturer requirements will also be discussed.

Learning Objectives: 

1. Describe and explain the difference between air barriers and thermal barriers

2. Determine and support air barriers at framing stage

3. Classify the quality of insulation installation

4. Interpret requirements for air barriers/mechanical inspection
