When it comes to keeping Rochester homes warm in the winter and cool in the summer, insulation is one of the most important investments you can make. Traditional options like fiberglass batts and blown-in cellulose have been around for decades, but modern building science points to a superior solution: spray foam insulation. At Sunset Roofing, we provide closed cell spray foam insulation that offers unmatched performance, durability, and energy efficiency compared to traditional methods.

What Is Spray Foam Insulation?

Spray foam insulation is a two-part liquid material that expands and hardens into a dense foam when applied. The foam fills gaps, cracks, and cavities, creating an airtight seal that traditional materials can’t match. Sunset Roofing installs closed cell spray foam, which is known for its rigidity, moisture resistance, and superior thermal performance.

The Science of Air Sealing

Traditional insulation works by slowing down heat transfer, but it doesn’t stop air movement. Small gaps around framing, outlets, or rooflines allow conditioned air to escape and unconditioned air to enter, which reduces comfort and efficiency. Spray foam, on the other hand, acts as both insulation and an air barrier. By expanding into every crevice, it eliminates drafts and seals the building envelope. The result? Consistent indoor temperatures and reduced energy waste.

Superior R-Value Performance

The insulating power of a material is measured by its R-value, or resistance to heat flow. Fiberglass batts average an R-value of 3.0–3.5 per inch, while cellulose typically measures around 3.2–3.8. Closed cell spray foam insulation provides an R-value of approximately 6.0–7.0 per inch — nearly double the effectiveness. This means you achieve higher performance with less material, making it especially effective in tight spaces and roof assemblies common in Rochester homes.

Moisture Resistance and Mold Prevention

Western New York homeowners know how much moisture can impact a house, from snowy winters to humid summers. Traditional insulation can absorb water, losing effectiveness and encouraging mold growth. Closed cell spray foam is water-resistant and creates a moisture barrier, preventing condensation and protecting your home’s structure from rot and mildew. This durability makes it a smart long-term investment in Rochester’s challenging climate.

Structural Benefits

Unlike fiberglass or cellulose, closed cell spray foam adds structural strength. Once cured, it hardens into a rigid material that reinforces walls and roof decks. This added stability is particularly valuable in areas prone to heavy snow loads or high winds, both of which Rochester residents are all too familiar with.

Energy Efficiency and Cost Savings

Energy efficiency is one of the biggest reasons homeowners switch to spray foam insulation. Because spray foam eliminates air leaks and provides superior thermal resistance, HVAC systems run more efficiently. According to the U.S. Department of Energy, up to 40% of a home’s energy loss is due to air leakage. With spray foam, homeowners often see energy savings of 20–40% on heating and cooling bills — savings that quickly offset the initial investment.

Noise Reduction Benefits

Spray foam doesn’t just insulate against temperature fluctuations — it also dampens sound. The dense, airtight barrier reduces noise transfer from outside and between rooms, making homes quieter and more comfortable. Traditional insulation simply can’t provide the same level of soundproofing.

Environmental Advantages

Because spray foam drastically reduces energy use, it contributes to a smaller carbon footprint. Homeowners who prioritize sustainability find spray foam a smarter choice than fiberglass or cellulose, which degrade more quickly and often need replacement sooner. The long-lasting nature of closed cell spray foam means fewer materials end up in landfills over time.

Why Traditional Options Fall Short

Fiberglass Insulation: Inexpensive but prone to gaps, air leakage, and moisture absorption. It also sags over time, reducing effectiveness.
Cellulose Insulation: Made from recycled materials but highly susceptible to moisture, settling, and mold growth.
Spray Foam Insulation: Airtight, moisture-resistant, structurally supportive, and energy efficient — outperforming traditional options in nearly every category.

Why Rochester Homes Benefit Most

Rochester’s four-season climate puts insulation to the test. Homes here face freezing winters with heavy snow, spring rains that test moisture barriers, hot and humid summers, and windy fall storms. Closed cell spray foam offers comprehensive protection against all of these challenges, making it the ideal insulation choice for Western New York homeowners.
