Insulation is an important part of a home. It greatly affects a home’s energy use and is critical in keeping the internal temperature of the house comfortable. Heat has the natural tendency to flow from a warm space to a cool space, causing heat transfer. During summer, hot air from the outside flows inside the house, making the house feel warmer. During winter, the warm air from inside the house will flow outside, making the house feel colder. Either way, the temperature inside the house will become uncomfortable for the dwellers if there is not an effective barrier to mitigate heat transfer.

Is Insulation Dangerous?

Naturally, the airconditioner helps during summer and heating helps during winter, but if a home is not efficient, the home’s heating and cooling systems will have to work overtime. You will see the evidence of this hard work in your elevated utility bills.

This is where insulation is needed. Insulation provides the barrier between the outside air and the inside air. It is placed inside the walls of the attic of the home to prevent heat transfer. Insulation keeps the house temperature comfortable with less help from either the air conditioning unit or the heater.

Fiberglass insulation is currently the most popular form of insulation used in homes. Fiberglass became popular as a replacement for asbestos. Asbestos was banned as an insulation material in 1989 by the Environmental Protection Agency after it was found to be carcinogenic.

Some people have expressed concern about the safety of fiberglass. Contact with fiberglass can irritate the skin and eyes. Inhaling fiberglass particles can obstruct breathing. There are some people who claim that fiberglass could also be carcinogenic, but there is insufficient evidence to substantiate this claim.

Fiberglass is widely considered to be safe when it is properly installed. During installation, fiberglass safely rests between panels and plaster. Fibers become airborne only when the insulation is being removed. Extreme care must be exercised when removing fiberglass insulation from homes. In fact, it is often best to leave this work to a professional.
