Spray Foam Insulation

Home Spray Foam Insulation in Kennesaw and Ft. Oglethorpe, GA

Spray foam insulation is a two-in-one home insulation and air sealing product that can help homes and businesses increase comfort and reduce energy consumption. Foam insulation expands when applied. While fiberglass insulation can be combined with air sealing, spray foam achieves both with one step.


Spray foam insulation has a variety of benefits for a homeowner:

  • Increased Comfort: It prevents drafts, improves air quality and enhances acoustics.
  • Energy and Cost Savings: You can reduce your monthly energy costs by 30% to 50%. With such significant energy savings, your spray foam insulation cost will be returned to you in a timely manner.
  • Reduced Outside Air Infiltration: It seals the home from air movement, helping to reduce pollen, dust and allergens.
  • Durability to Last a Lifetime: Once applied, spray foam insulation will not shrink, sag or settle — even if it comes into contact with water. It sticks to a wide variety of materials including masonry, cement, metal studs, wood studs and rooflines. Foam insulation can even be used to insulate garage doors!

Our expert team of spray foam insulation contractors at Foster Insulation is ready to answer all your questions about insulation and what the spray foam insulation cost will be for your Kennesaw or Ft. Oglethorpe home project.

Types of Spray Foam Insulation

There are two different types of foam insulation: Open Cell Spray Foam and Closed Cell Spray Foam. They each have unique benefits.

Open Cell Spray Foam Insulation

Open cell foam insulation works as an insulator and air barrier. Weighing only 0.5 pounds per cubic foot, open cell spray foam gets its name from its broken cell structure. This allows air to fill the empty space inside the material. The typical R-value of open cell foam is 3.7 per inch. Open cell spray foam insulation is vapor permeable, dampens sounds and eliminates air infiltration.

Closed Cell Spray Foam

Like open cell foam insulation, closed cell insulation works as an insulator and air barrier. Closed cell insulation is solid and denser than open cell spray foam. The cells of the bubbles remain intact, which makes the material rigid. The closed cell composition and increased density contribute to a higher R-value than that of open cell foam insulation. Higher density allows closed cell insulation to contribute to building stability during storms and high winds.

Spray foam provides both an air sealing and insulating solution and is built to endure more severe weather conditions than fiberglass insulation. This makes the cost of spray foam insulation an investment that is worth every penny. While spray foam is commonly thought of for new construction, spray foam insulation can be installed in existing homes.
