Fiberglass Insulation

Fiberglass is a popular insulating and heat-retaining material, widely used in construction for the purposes of heat preservation and sound insulation. Due to its unique structure, it is not subject to corrosion. It firmly retains heat or cold but, at the same time, does not interfere with ventilation in the room. This material is widely used, mostly for the purposes of insulation, protection against corrosion, and sound transmission.

Typically composed of fine fibers, fiberglass comes in several forms:

  • Loose-fill fiberglass insulation (tiny glass fibers that you blow or pour into the wall cavity);

  • Blanket form of insulation (available in the form of fiberglass insulation batts or rolls, which you wrap around or lay on top of surfaces).

Why Installing Fiberglass Insulation?

Fiberglass, as an insulator, slows the spread of heat, cold, and sound in structures. Limiting the amount of air coming into and leaking from a home can work to make a home comfortable. It's important to note that fiberglass limits air movement but doesn't stop it completely.

If you're searching for a way to reduce your heating and cooling bills, boost your thermal protection, and improve indoor air quality, fiberglass material is what you need! If properly installed, this energy-efficient and environmentally friendly material not only prevents homeowners from experiencing redundant heat loss or gain but also hinders access to outdoor pollutants and allergens.

Fiberglass Insulation Uses

Glass wool is most often used as a heat and sound-insulating material indoors, since it quickly loses its insulating properties when in contact with moisture. Fiberglass insulation is used under pitched roofs, wood floors, and interior walls. This is a great option for residential and commercial projects.

Installation of fiberglass insulation aids in isolating rooms and attics, floors and ceilings, unfinished walls, pipes, and ducts with rigid boards or soft batts. 

Working both for vertical and horizontal applications, it goes between beams and joists, ensuring thermal resistance and sound control.

Fiberglass Advantages & Benefits

Take a look at some of the most important advantages of fiberglass:

  • Cost-effectiveness
  • High thermal performance
  • Fire Resistance
  • Acoustic control
  • Secondary raw materials
  • Energy efficiency

Cost Effectiveness

The fiberglass insulation reduces the need for continual heating and cooling since it blocks air heat transfer. Typically, the installation costs are quite reasonable for fiberglass insulation. Moreover, this material has a long lifespan and provides thermal resistance for many years without replacement if treated properly. Thus, to prevent dampness and mold from spreading from the exterior walls to the fiberglass batts, it's important to consider additional sealing, a vapor barrier, or other means of moisture control.

High Thermal Performance

Good-quality fiberglass insulation hampers the movement of heat in and out of the building, sealing it and allowing it to maintain the most comfortable temperature for human living. Fiberglass is a material with an exceptional ability to trap air in the pockets due to its composition: the fibers are arranged closely but not in a continuous, end-to-end manner.

Fire Resistance

No matter if it's fiberglass batt insulation, loose-fill insulation, or board insulation, they all share one property: they are non-combustible. And if we speak about faced fiberglass, the fire-resistant facing helps the material not only to not catch fire but also stop its rapid spreading, acting as a barrier for the fire and providing you with extra time to leave the place or call the firefighters.

Acoustic Control

Some people use acoustical insulation to manage sound transmission. If your walls are thin or your neighbors are loud, fiberglass insulation is one of the most effective means of sound control. By absorbing sound waves and suppressing the noise, the material makes it hard to reach areas within your four walls. More so, fiberglass insulation reduces the ability of the sound to reflect, which ensures a calmer and more peaceful environment in your home.

Secondary Raw Materials

Fiberglass insulation material consists of recycled glass that undergoes a thermal treatment. Then, the fabricators transform it into fine fibers bound together that come in the form of fiberglass batts, blankets, rolls of different thicknesses, and R-values. By using recycled glass, we can lessen the amount of new resources that otherwise would be taken from the planet and also decrease the emissions from processing them. This makes the material eco-friendly.

Energy efficiency

Homeowners always care about energy efficiency, at least because it is reflected in their bills. By installing fiberglass insulation, you ensure proper preservation of heat or cooling through the use of air pockets. Insulation helps to trap air inside the place, thereby regulating the heat flow. Such thermal control allows you to save energy on the operation of the air conditioner and heaters, keeping the premises cool in the hot summer and warm in the cold winter.

Fiberglass Insulation for Your Property

How do I choose the proper type of insulation material? Besides studying building codes and insulation types, it's also essential to keep in mind the following factors:


R-value is the measurement of the insulation's thermal resistance. Materials with high R-values have better insulation properties, perfect for supporting consistent temperatures indoors, while materials with lower R-values signify a milder ability to stop the flow of heat. However, low-R-value fiberglass may be sufficient for regions with temperate climates and is less expensive in comparison with other options.

Method of installation

If you choose to install fiberglass, you will find out that it's relatively easy. The material effortlessly fits in the spacing between rim joists and studs, and is also well-suited for such areas as crawl spaces. Thanks to its versatile form and composition, fiberglass is easy to handle, reshape, and fit into different areas.


In comparison with other materials, fiberglass insulation is one of the most cost-effective options, both in terms of prime cost and installation cost. Yet, the project's scale, the particular fiberglass insulation's properties, and other factors may affect the expanses.


According to this parameter, fiberglass insulation can have a lower environmental impact. Firstly, you get it from recycled materials. Secondly, it's possible to recycle fiberglass at the end of its life. And finally, fiberglass insulation with a high R-value helps reduce energy consumption during its lifespan.

Fire resistance and moisture resistance

Fire-retardant features and abilities to control moisture intake may play a big role in your decision-making process. Not only do building codes require the insulation to be safe for occupants, but its elemental resistance is also vital for the structure's longevity and overall air quality in the building.
