Well, the truth is… if you’re looking for a modern, high-performance option and have the budget for it, spray foam outperforms fiberglass—especially in air sealing and overall comfort. Fiberglass still does a solid job and remains a reliable, code-approved material, it just doesn’t deliver the same level of coverage or efficiency that foam is designed to provide.

Most residential projects are completed within a few hours, while larger commercial projects may take longer depending on the scope of work.

R-value is simply the measurement of how well insulation resists heat flow — the higher the R-value, the stronger the protection, the greater the efficiency, and the more controlled your home feels.

Closed-cell spray foam is recommended for crawlspaces, basements, exterior walls, metal buildings, and any area where strength, moisture control, and high R-value are needed. Open-cell spray foam is typically used for attic rooflines, bonus rooms, and interior walls because it expands more, fills irregular spaces, improves comfort, and offers better sound control at a lower cost. Both are high-performance options — closed cell is the durable, moisture-resistant choice, while open cell is the flexible, budget-friendly choice for creating a comfortable, conditioned space.

Airflow is the movement of actual air through gaps, cracks, and openings due to pressure differences, while heat flow is the movement of heat through materials because of temperature differences. Airflow is controlled by sealing the leaks; heat flow is controlled by insulation and R-value. One stops drafts, the other slows energy loss — and together they determine how efficient and comfortable a home truly feels.

According to ENERGY STAR, a properly sealed and insulated home can reduce heating and cooling costs by about 15%, and in Georgia that typically translates to $300–$800 per year in real savings — all while making the home feel more stable and comfortable year-round. But in homes with major air leakage — especially attics with HVAC units — the improvement can reach closer to 30% because you’re fixing a much bigger problem

Not always — blown-in fiberglass can typically be added on top unless the existing insulation is moldy, wet, or contaminated.
