Article Preface:

Spray Polyurethane Foam Insulation has become a huge part of our conversation. To prepare for our October 2025 continuing education classes, the Association joined the Spray Polyurethane Foam Alliance. They have an amazing amount of technical and installation material. We are pleased to have a close relationship with SPFA and believe that all foam-ers should be members of their Association. This is the first of what we hope will be a series of articles to inform the HVACR industry, educators, foam-ers, and homeowners how to use and enjoy the benefits of Polyurethane foam. In fact, we hope they will supply training materials to our college energy and construction education programs. These articles and information represent the research and opinions of SPFA and are for your consideration; however, as with all products, we recommend that you get approvals from your local inspectors before using any equipment or product.

• Energy savings, with potential reductions of up to 30% or more in heating and cooling costs. • Durability and longevity • Sound dampening • Flood resistance* * closed-cell SPF However, realizing the full potential of SPF insulation requires collaboration between HVAC and insulation contractors during the early stages of design and planning – for both new and existing buildings. Proper system sizing and ventilation strategies are critical, especially given the airtight nature of SPF-sealed enclosures. Oversized or undersized HVAC systems can compromise energy efficiency, occupant comfort, moisture management and indoor air quality. Additionally, SPF insulation introduces specific fire protection considerations that may influence HVAC system design. These requirements must be addressed proactively to ensure compliance with building codes and to maintain occupant safety.

Spray Foam and HVAC- What HVAC Contractors Need to Know Integrating high-efficiency HVAC systems with a building envelope insulated and air-sealed using spray polyurethane foam (SPF) creates energy-efficient, durable structures that offer superior comfort for occupants. SPF insulation provides a range of benefits, including: • Highest R-values per inch among insulation materials*. • Air sealing and moisture control*, reducing drafts and preventing mold and mildew. • Improved indoor air quality by minimizing allergens and pollutants. • Enhanced structural integrity*.
