Benefits of fiberglass insulation

Nowadays, a whopping eighty-five percent of homeowners in America are insulating their attics with fiberglass. Fiberglass insulation is one of the most dynamic attic insulators and is also one of the most cost-effective.

The following are some benefits of fiberglass attic insulation.

Moisture and fire-resistant

One of the risks involved with owning a home is the potential for damage to property brought about by natural calamities. Luckily, in case of flood or fire, you can depend on fiberglass to resist them.

Fiberglass is not perfectly waterproof and thus can become damp. However, it neither retains nor holds water, making it easy to dry and fix it back in the attic. Moreover, fiberglass is good at moisture resistance means that you will not have to worry about mildew or mold growth on it.

Fiberglass is noncombustible, a coveted attribute since, in most cases, installing attic insulation requires lining material within wooden joists.

Easy to Install

Whereas fixing some popular insulators in your attic is challenging, installation of fiberglass batts is quite easy. The batts are designed such that they are of a similar width to the distance between wall studs.

Available in loose-fill form too

Although batts are often easy to fix, the task might turn to more challenging for attics with:

  • Pipes on the walls
  • Less headroom and crawl space to maneuver around
  • Cumbersome spacing between joists
  • Cooling and heating units on the ground

Luckily, you can avoid the headache of dicing fiberglass batts to certain sizes by going for the loose-fill insulation option.


Although fiberglass products are fantastic insulators, you would not tell from the price. In some instances, you can get it under one dollar per square foot. The price and savings on energy consumption make fiberglass an ideal option for home insulation compared to foam.
