Can independent data prove that spray foam performs better in freezing northern winters? Yes. The Spray Polyurethane Foam Alliance (SPFA) conducted an extensive Life Cycle Assessment comparing spray foam to traditional fiberglass in Climate Zone 6 (the upper Midwest cold climate).

The study proved that while spray foam has a higher initial material density, its inherent air-impermeability prevents the freezing northern wind from cutting through the building envelope. The energy modeling revealed that replacing fiberglass with spray foam in a single northern home saves so much cumulative heating energy that it is the environmental equivalent of removing 14 to 23 cars from the road for an entire year.

Why do standard insulation ratings fail in the brutal Wisconsin winter? Because standard lab tests for fiberglass assume zero wind and zero moisture—conditions that don't exist in the real world. When wind blows or moisture condenses, traditional insulation values collapse. Spray foam creates a total air and moisture seal that maintains its performance regardless of the weather.

Traditional vented attics often lead to significant energy loss, particularly when HVAC systems and ducts are exposed to extreme temperatures and air leakage. Transitioning to an unvented, conditioned attic by applying spray foam insulation directly under the roof deck effectively brings the HVAC system into the home's conditioned envelope, which can reduce heating and cooling energy use by 10% or more. Read below to learn how closed-cell spray foam is an ideal solution for any climate because it offers the highest R-value, acts as a vapor retarder, and creates an exceptionally tight air seal that prevents moisture problems like mold and wood rot. Beyond superior energy efficiency and moisture resistance, unvented attics provide enhanced disaster protection against high winds, wildfires, and wind-driven rain, ultimately creating a more durable and comfortable home.

The following article provides essential health and safety information regarding the use of Spray Polyurethane Foam (SPF) insulation in homes and buildings. Readers will learn about the versatile applications of SPF for energy efficiency, the importance of professional training and personal protective equipment, and the critical differences between worker reentry and occupant reoccupancy times.
