What Is Fiberglass Insulation?

Stack of yellow wall heat insulation material.

Fiberglass insulation is one of the most used insulating materials in the present construction due to the ability to insulate against both thermal and sound. But what do they put into making this material? Now it’s time to look at what fiberglass insulation is made of, how it is made, and what it has to offer.

Benefits of Fiberglass Insulation

Fiberglass insulation is widely used for many reasons. It gives good thermal performance, which is useful in regulating temperature inside structures besides lowering the energy consumption. It is safer than most of the other insulation materials as it is resistant to fire since it does not spread flames or come up with toxic gases when exposed to heat. Further, fiberglass is acknowledged to have high sound-absorbing qualities and is thus useful in noise control. It also has the added benefit of being less costly and requiring less effort to install, making it a favorite with homeowners as well as builders.

What Is Fiberglass Insulation Made Of?

Fiberglass insulation, in other words, simply consists of fine glass fibers. These fibers are made mainly from silica sand, which is mixed with other ingredients such as limestone, soda ash, borax, and other minerals to produce molten glass. This mixture is then spun into fine fibers, as the molten glass is literally spun through holes in a disk to form fibers similar to making cotton candy. These fibers are during production coated with a binder, commonly an organic material such as phenol formaldehyde, which assists in holding the fibers collectively and imparts the fluffy nature of the insulation.

How Is Fiberglass Insulation Made?

The fiberglass insulation manufacturing process can be described by the following steps: First of all, the primary materials are heated to temperatures of approximately 1450 degrees Celsius. This molten mixture is then extruded through small orifices in a high speed machine and drawn out into thin filaments. These fibers drop on a conveyor belt, where they are treated with a binder and then baked in an oven to set the structure of the insulation. The final product can be formed into batts, rolls, or loose fill according to the purpose of use.

Conclusion

Knowing what fiberglass insulation is made from not only helps explain this common product but also understands the usefulness of fiberglass for increasing the efficiency and comfort of buildings.

FAQs on Fiberglass Insulation

Q: Is fiberglass insulation safe to use?

A: When properly installed and not disturbed, fiberglass insulation is safe. However, during installation or if the material becomes damaged, it can release fibers that might irritate the skin or respiratory system. Protective gear like gloves, masks, and long-sleeved clothing is recommended during handling.

Q: Can fiberglass insulation be recycled?

A: Yes, fiberglass insulation can be recycled. Many manufacturers use recycled glass in their production processes, contributing to sustainability efforts.

Q: How long does fiberglass insulation last?

A: When installed correctly, fiberglass can last the lifetime of the building without significant degradation, although it's generally recommended to check for settling or compression over time
