Fiberglass Insulation

Home Fiberglass Insulation in Kennesaw and Ft. Oglethorpe, GA

When it comes to insulation upgrades in Kennesaw, GA, most people are thinking about fiberglass. One of the reasons is because fiberglass insulation is the most common and widely used form of thermal energy protection.

Manufacturers craft this material from recycled glass, which is spun into thermal-resistant fibers. The insulation is then cut into strips (also called batts) to fit the framing in most houses. Fiberglass is also manufactured as blown-in insulation. Blown-in insulation is ideal for blowing into open spaces and/or densely packing into closed cavities.

Fiberglass insulation is most effective when installed by professional insulation contractors, and Foster Insulation is the company you can trust to do the job right. We possess the experience needed to install fiberglass correctly, and we take great pride in our work. Contact us today! We are always excited to provide advice to our customers


Fiberglass insulation has been around for years. It provides a wealth of benefits including creating comfortable living conditions. We want our customers to understand the benefits of attic insulation as a whole. Adding insulation to a home helps reduce energy bills across the board. Fiberglass is a great choice because it:

Has Excellent Acoustics: Soundproofing is an underrated quality of insulation. Most people tend to think about thermal protection, but you should also consider fiberglass insulation for soundproofing your home.

Is Noncorrosive: Fiberglass will not corrode or degrade over time. This quality is essential to help insulation function correctly.

Is Lightweight: Fiberglass isn’t just durable — it’s also lightweight. Its ability to provide superior weather, moisture, and sound protection without heft or bulkiness is a huge plus for any home.

Is Performance Certified: Industry leaders certify fiberglass for superior indoor air quality (IAQ) performance. This quality is essential, especially in older homes which tend to be more susceptible to air quality issues. Homeowners with allergies also appreciate the benefits of this top quality insulation material.


Foster Insulation installs several kinds of fiberglass insulation. One of the most popular is fiberglass batt insulation. The ideal locations for fiberglass batt insulation are open wall cavities and between ceiling joists. These areas occur throughout the house and on all floors. The batts are cut into pieces to fit between joists, making it easy for our specialists to install the insulation. Fiberglass batt insulation has numerous benefits:

  • It creates yearlong comfortable living and working conditions
  • It is more cost effective than other forms of insulation
  • It improves energy efficiency
  • It can lower energy bills
  • It decreases sound transfer and creates noise control


In addition to batt insulation, Foster Insulation offers blown in fiberglass insulation to insulate open attic spaces. Combined with air sealing, this type of insulation provides exceptional energy efficiency — it can cut your energy costs by as much as 50% by creating a thermal barrier. We utilize blown in fiberglass insulation in numerous areas throughout a home, including:

  • Densely packed into interior walls — fiberglass wall insulation creates a strong thermal barrier between rooms
  • Between floors for enhanced control through fiberglass sound insulation
  • Sloped areas found in spaces like attics
  • In attic knee walls


Foster Insulation wants you to understand there are cost effective ways to keep your home comfortable and reduce your energy bills. Fiberglass is the perfect way to do so. For many homeowners, combining air sealing with insulation is a dual approach to reducing air leakage and creating a thermal barrier. We offer free estimates and take the time to carefully review your home’s dynamics. Our goal is to insulate your home in one trip. We also understand that fiberglass isn’t the right material for every project, so we offer alternatives to fiberglass insulation like spray foam insulation.
