Open-Cell vs. Closed-Cell Spray Foam

Open-Cell vs. Closed-Cell Spray Foam: Which Is Right for You?

Choosing between open-cell and closed-cell spray foam is one of the most common decisions Minneapolis homeowners face when planning a spray-foam project. Both options have real trade-offs in cost, lifespan, and day-to-day use — and the right pick depends on your property, your budget, and how long you plan to stay in the home. This guide breaks the decision down in plain language so you can walk into a consultation knowing exactly what to ask.
