This course explores the below grade use of polyisocyanurate (POLYISO) insulation to meet energy code and maximize thermal performance of the building foundation. Let us help dispel the myths that have been created relative to POLYISO insulation while discussing its thermal performance, water absorption, and load capacity – the three primary characteristics for below grade insulation. In addition, we will discuss how the insulation can provide protection for the foundation waterproofing system.

Learning Objectives: 
  1. Review why buildings are insulated below grade and how to obtain the best performance
  2. Review codes and standards that apply to below grade applications and insulation
  3. Understand testing that validates POLYISO as a below grade option, and how it compares to other materials
  4. Understand below grade POLYISO insulation applications and how they meet specific project requirements
