Your attic is the single largest source of energy waste in your home. Heat rises, and without proper roof deck sealing, conditioned air escapes through gaps, cracks, and porous surfaces—driving up utility bills and forcing HVAC systems to work harder. Spray polyurethane foam attic insulation creates an airtight thermal envelope that stops this cycle.
Octofoam, LLC specializes in professional spray foam applications that transform attics from energy liabilities into high-performance barriers. Homes in Greenfield face humid summers and freezing winters, conditions that demand insulation solutions capable of handling extreme temperature swings and preventing condensation buildup. Traditional fiberglass batts settle, leave gaps, and allow air movement—spray foam adheres to every surface, forming a continuous seal.
According to the U.S. Department of Energy, air sealing and insulation upgrades can reduce heating and cooling costs by up to 20 percent annually. The investment in roof deck sealing pays dividends through lower monthly bills, improved indoor comfort, and better air quality by keeping outdoor allergens, dust, and pollutants from infiltrating living spaces.
How Roof Deck Sealing Works for Greenfield Homes
Greenfield sits in Hancock County, where summer humidity often exceeds 70 percent and winter temperatures regularly dip below 20°F. These conditions create challenges for traditional insulation materials that absorb moisture, compress over time, and lose effectiveness. Spray polyurethane foam expands on contact, filling voids around rafters, ductwork, and penetrations to create a monolithic barrier that resists moisture infiltration and air movement.
The application process involves spraying liquid foam directly onto the underside of roof decking. Within seconds, the material expands to many times its original volume, bonding permanently to wood, metal, and concrete surfaces. This creates both an air barrier and a vapor retarder, preventing condensation that leads to mold growth, wood rot, and compromised structural integrity. The closed-cell formulation offers an R-value of approximately 6.5 per inch—nearly double that of fiberglass.
Properly sealed attics also reduce the workload on HVAC equipment, extending system lifespan and reducing repair frequency. Research from Oak Ridge National Laboratory shows that uncontrolled air leakage accounts for 25 to 40 percent of heating and cooling energy use in typical homes.

Why Choose Spray Foam for Your Attic
Homeowners across Greenfield are discovering the transformative benefits of spray polyurethane foam attic insulation. Beyond energy savings, this solution addresses multiple concerns simultaneously:
- Eliminates air infiltration through roof penetrations, reducing drafts and temperature fluctuations throughout the home
- Prevents moisture accumulation that leads to mold, mildew, and allergen growth—critical for residents with asthma or respiratory sensitivities
- Strengthens roof structure by adding rigidity to decking, particularly beneficial for older homes in Greenfield's historic neighborhoods
- Reduces outdoor noise transmission, creating quieter indoor environments especially near U.S. Route 40 and State Road 9
- Increases resale value through documented energy performance improvements and modern insulation certifications
The Environmental Protection Agency estimates that improved insulation and air sealing can reduce household carbon emissions by approximately 2,000 pounds per year. For families committed to sustainability and long-term home value, spray foam attic insulation represents a proven solution that delivers measurable results.
