Technical Bulletin #304 discusses how to use Polyiso CI (with foil or coated glass facer) to provide a continuous layer of insulation on the exterior of homes with wood or steel framing to minimize thermal bridges. Architectural images depict insulation covering the entire opaque wall surface that demonstrate significant increases in the overall thermal performance and energy efficiency of a home using Polyiso CI.
Thermal images highlight the temperature distribution and heat flux through wood and steel frame wall sections both with and without Polyiso CI and demonstrate an improved overall effective R-value. The technical bulletin also discusses Polyiso CI’s features and benefits related to attic, roof, foundation, and slab applications.
