Many homebuilders are drawn to the use of SPF because it can provide an all‐in‐one solution for: High R‐Value Insulation Air‐Barrier / Vapor Barrier Increased Racking Strength / Wind Uplift TABLE OF CONTENTS Improved Indoor Air Quality (IAQ) Challenging Geometry / Architecture GENERAL INFORMATION Many Other Demands o SPF Overview PPT (SPFA) o SPF Attic PPT (SFC) Sprayfoam is a field‐installed product. Being field‐installed allows SPF to realize its o LCA – Short Report greatest benefit: producing a tightly‐sealed building envelope resulting in substantial o LCA – Long Report energy cost‐savings and other benefits for the owner. This is a notable value‐add for a FIRE SAFETY homebuilder and one of the best ways a builder can differentiate itself from the o ICC‐ES AC‐377 competition. o Decoding Thermal and Ignition However, SPF is also a complex product that requires installation by a trained, Barriers PPT qualified, and ideally SPFA‐Certified professional contractor.
