Fiberglass Insulation

Fiberglass Insulation for Florida’s East Coast

Many Florida homeowners do not realize the importance of having a well insulated home. Because we have mild winters, many homeowners mistakenly think they do not need to worry about home insulation. But insulation works not only during the winter to keep the warm, toasty inside air from escaping to the cold outside, it also keeps the cool, conditioned air from escaping into the hot, humid temperatures outside during the summer months.

What is Fiberglass Insulation?

There are a variety of places in your home that require different amounts and types of insulation. The most common and widely used type of insulation is fiberglass insulation. Made from recycled glass that is spun to create small fibers, it is then formed into fiberglass batts/rolls or small pieces of loose-fill or blown-in fiberglass that can be used for insulating most areas of your home such as walls, ceilings, and the attic. Fiberglass batt insulation resembles pink cotton candy and is the most recognizable type of insulation.

Benefits of Fiberglass Insulation

Here are some of the advantages of using fiberglass insulation in your home:

Cost Effective

Fiberglass is less expensive than other types of insulation but just as effective.

Energy Efficient

Fiberglass is one of the most energy efficient insulation options available to homeowners.


Made of a precise combination of glass, sand, and recycled materials, fiberglass insulation is better for the environment.

Absorbs Sound

Fiberglass is excellent at minimizing noise transfer from room to room and outside, making your home a quieter place to be.

Quick and Easy to Install

Both blown-in and fiberglass batts are installed in a quick and easy time frame by professionals.


Fiberglass is noncorrosive and noncombustible, does not absorb moisture, and does not deteriorate with age.

Types of Fiberglass Insulation

Fiberglass Batt Insulation

Batt or roll insulation is a blanket type of insulation that is perfect for unfinished walls, floors, and ceilings. It comes in a variety of widths for a snug fit between wall studs, attic and floor joists, and beams. Its level of thermal effectiveness is dependent on proper installation so it is important to hire a professional for the job.

Blown-In Fiberglass Insulation

Blown-in or loose-fill fiberglass insulation is commonly used to insulate a home’s attic, but it can be installed in nearly any space in a home including between floors, and interior and exterior walls. Loose fiberglass fibers are blown into an open area or space to create a blanket of protection for your home. Insulation can be blown into hard-to-reach spaces or densely packed into closed cavities to ensure your home is properly insulated.
