Re-thinking Your Insulation Strategies

Wednesday May 8, 9:45am – 10:45am

Regency Ballroom

Many people in the construction industry involved with the design of exterior wall assemblies rely on the prescriptive requirements of the International Energy Conservation Code (IECC) in designing exterior wall assemblies. What could be wrong with the strategy of complying with prescriptive code requirements? Actually, a lot. The presentation will address the shortcomings of the IEC’s prescriptive requirements and show through hygrothermal analyses when compliance with such requirement can result in exterior wall assembly failures, discuss why they fail and offer solutions to avoid such failures.

Learning Objectives:

  1. Learn the prescriptive requirements for insulation for above grade vertical walls in the International Energy Conservation Code.
  2. Learn the performance requirements for insulation for above grade vertical walls in the International Energy Conservation Code.
  3. Learn the conditions that can cause moisture related failures in walls that comply with the prescriptive requirements of the International Energy Conservation Code.
  4. Learn how to use the performance requirements in the International Energy Conservation Code to avoid moisture related failures.
