Debunking the Myths: The Truth About Spray Foam Insulation

Spray foam insulation has quickly become one of the most effective and energy-efficient options for homeowners and builders alike. Yet despite its growing popularity, there are still a few persistent myths that create confusion—and can keep people from making a smart investment in their home.

At Blue Ridge Insulation, we believe in honest, expert guidance. So let’s clear the air and set the record straight on some of the most common misconceptions about spray foam insulation.

❌ Myth #1: “Spray Foam Is Too Expensive”

✅ The Truth:

Yes, spray foam typically has a higher upfront cost than traditional insulation—but it pays for itself over time through major energy savings. Its superior air-sealing abilities help reduce heating and cooling costs by up to 30% or more. Plus, it can increase home resale value, reduce HVAC wear, and even qualify for energy efficiency rebates.

❌ Myth #2: “Spray Foam is Dangerous or Toxic”

✅ The Truth:

When installed by trained professionals like our team at Blueridge Insulation, spray foam is completely safe. The material is inert once cured and poses no health risks when properly applied. We follow strict safety and ventilation protocols during installation to protect you, your family, and your property.

❌ Myth #3: “Spray Foam Can Damage My Roof”

✅ The Truth:

This rumor often stems from misinformation. Spray foam is commonly applied directly to roof decks to improve efficiency and prevent moisture buildup. In fact, closed-cell foam adds structural strength and can help prevent issues caused by condensation or air leakage—prolonging your roof’s life when installed correctly.

❌ Myth #4: “You Shouldn’t Use Spray Foam in Cold Climates”

✅ The Truth:

Quite the opposite—spray foam performs exceptionally well in cold climates. It offers one of the highest R-values per inch, creating a strong thermal barrier that reduces drafts and keeps heat inside where it belongs. It’s also an excellent moisture barrier, protecting against frozen pipes and ice dams.

❌ Myth #5: “Spray Foam Is Only for New Construction”

✅ The Truth:

Spray foam is a fantastic solution for both new builds and existing homes. It can be used in attics, crawl spaces, rim joists, and more—even in retrofit projects. Our team is experienced in applying spray foam in tight and irregular spaces, offering custom solutions for homes of any age.
