Project: Historic Draft Reduction near Lake Winnebago A homeowner in a 1920s residence near the lake struggled with freezing floors and high heating bills due to a porous stone foundation. We implemented a Closed-Cell Spray Foam application to the rim joists and crawl space walls. The result was an immediate 20% reduction in heating costs and the elimination of cold drafts, restoring comfort to the first floor without altering the home's historic exterior.
Don't let another season pass with high energy costs and uncomfortable drafts. Contact Proseal Spray Foam today to schedule your assessment.
Unlike fiberglass, which acts like a wool sweater allowing air to pass through, spray foam expands to create an air-tight seal. In Neenah's climate, this is crucial for stopping the cold winter air from penetrating the home and prevents warm, moist air from escaping, which reduces the risk of ice dams.
Yes, we often use a technique called "injection foam" or retrofitting with dense pack cellulose for existing finished walls. However, for attics, crawl spaces, and basements—where the framing is exposed—spray foam can be applied directly to the substrate with no demolition required.
Generally, yes. Closed-cell foam is impermeable to water and acts as a vapor barrier, making it the superior choice for basements and crawl spaces where ground moisture is a concern. Open-cell foam is better suited for dry, interior cavities or roof decks where water resistance is less critical.
Absolutely. A significant amount of cold air enters a home through the rim joists and foundation of the crawl space (the "stack effect"). By sealing and insulating this area, you prevent cold air from cooling your floors and ducts, reducing the workload on your furnace.
When applied correctly by professionals, spray foam insulation is an indefinite solution. It does not sag, settle, or degrade over time like cellulose or fiberglass can. It typically lasts for the lifespan of the building, making it a "one-and-done" investment for your property.
