Fiberglass insulation is the most common type of residential insulator Fiberglass Insulationmade up of fine glass fibers. At homes, the fiberglass is used as an insulator in two prime forms – as blankets or loosely. The fiberglass, when installed as an insulator, reduces speed by which heat spreads in closed structures such as an attic. The fiberglass insulation works by trapping the pockets of the air and preventing unnecessary heating of the room.

The fiberglass insulation is considered to be the best alternative to home insulation and conserving energy. Fiberglass as an alternative choice to home insulation can help reduce electricity bills by almost 40% by increasing energy efficiency 12 times more than the other insulators.

How Fiberglass Works?

You must have studied in school that glass is a bad conductor of heat. It doesn’t allow the heat to pass through the glass. In short, the glass prevents conductive heat transfer. The fiberglass traps the heat when it is moving to the colder area. For instance, the fiberglass will prevent heat to pass out of your house in winter and enter your house in summer. The fiberglass can be installed anywhere in your house such as walls and attics.

A successful installation of the fiber insulation can help you save on electricity bills throughout the year. Although fiberglass insulators are considered to be best for residential usage, they are potent to trap allergens, dust, and moisture. If you or anyone in your family are asthmatic it is advisable not to go for fiberglass insulator.
