1. What is spray foam insulation?
Spray foam is a two-part liquid that expands into a solid foam when applied, sealing gaps and insulating your home or building at the same time. It outperforms traditional fiberglass batts by creating an airtight barrier that reduces energy loss.
2. How much does spray foam insulation cost?
Spray foam insulation typically costs between $1.50 and $3.50 per square foot depending on the type (open-cell vs. closed-cell) and the area being insulated. Every project is different — contact 605 Spray Foam for a free estimate tailored to your space.
3. Is spray foam insulation worth it?
Yes. Most homeowners see significant savings on heating and cooling bills, often enough to offset the upfront cost within a few years. It also improves air quality, reduces moisture, and can increase your home’s resale value.
4. What’s the difference between open-cell and closed-cell spray foam?
Open-cell foam is softer, less dense, and better for interior walls and soundproofing. Closed-cell foam is denser, waterproof, and ideal for exterior walls, basements, and crawl spaces. 605 Spray Foam can help you decide which is right for your project.
5. Can spray foam insulation be used in existing homes?
Absolutely. Spray foam can be applied in attics, crawl spaces, rim joists, and existing walls with minimal disruption. It’s one of the best upgrades you can make to an older home in South Dakota’s climate.
6. How long does spray foam insulation last?
Spray foam can last the lifetime of your building — often 80+ years — without sagging, settling, or losing effectiveness like traditional insulation can over time.
7. Does spray foam insulation prevent moisture and mold?
Closed-cell spray foam acts as a vapor barrier, preventing moisture from entering your walls and reducing the risk of mold growth. This makes it especially valuable in South Dakota where temperature swings cause condensation issues.
