If you’re looking for a way to keep your home feeling comfortable, while also cutting down on your energy costs, installing insulation is a great option. When it comes to choosing which insulation is right for your home, there are several products to choose from, each with its own set of benefits. First introduced in the late 1930s, fiberglass has remained the most popular insulation material used in both residential and commercial construction projects. In this article, we will take a look at some of the top benefits of using fiberglass insulation in your construction projects. 

What is Fiberglass Insulation?

Fiberglass insulation is composed of extremely fine glass fibers. Typically, it will come in a blanket form; however, you can also find fiberglass insulation in loose-fill form. Fiberglass insulation works as an insulator by trapping air and slowing the transfer of heat. 

The resistance to heat flow, which is measured by the R-value, is determined by the thickness of the fiberglass batts. The R-value ranges from R11 to R19 for walls and can go up as high as R30 for ceilings and attics. 

Benefits of Using Fiberglass Insulation

Fiberglass insulation provides several benefits for builders and homeowners, including the following: 

More Eco-Friendly

One of the great benefits of fiberglass insulation is that it is better for the environment. It is primarily composed of recycled content; in fact, some fiberglass insulation products are composed of up to 80% recycled glass. 

High-Quality Thermal Performance

Whether you are trying to cool your home during the summer or keep it warm and cozy during the winter, fiberglass insulation helps keep your home at the desired temperature. Not only does this keep your home feeling more comfortable, but it also helps to lower your monthly utility costs. 

Resistant to Moisture and Fire

Perhaps one of the best qualities of fiberglass insulation is that it is resistant to both moisture and fire. It does not absorb or hold water. Because of this, it is less likely to develop moisture related damage, like mold, mildew, or wood rot. Also, it is naturally noncombustible, which is great for helping builders adhere to fire codes!

Cost Advantage

Although the cost can vary based on which material is being used, fiberglass insulation is one of the less expensive materials out there. Not only is fiberglass one of the cheaper options, but it is also extremely durable and has corrosion-resistant properties. On average, you can find fiberglass insulation for $1 per square foot, sometimes even less. 

Easy to Install

Aside from being one of the more affordable options for insulation, fiberglass is also one of the easiest materials to work with and install. Fiberglass insulation comes available in pre-cut panels, rolls and loose-fill, making it super flexible for installation. 


Fiberglass is sound-absorbent material, drastically reducing the transmission of sound in your home. Generally, the first inch of fiberglass insulation increases an assembly’s sound transmission class value by 3-4 points.
