Every home should have some form of insulation to help regulate heat in the walls and attic space. Not only can the proper amount of insulation reduce the amount of heated or cooled air that is released into the atmosphere, it can also help reduce the amount of energy the home may be using. One of the most popular types of insulation is fiberglass insulation. A Houston roofing contractor can provide more information about the advantages and disadvantages of fiberglass insulation.
Fiberglass insulation usually comes in batts or rolls that can be pushed into the attic floor or sides. Some of the batts come precut while other types must be cut down to size. The insulation is comprised of thin strands of glass, making the material lightweight and cost effective. The thin strands are efficient at trapping heat and retaining a set temperature.
There are many advantages to choosing to install fiberglass insulation. Fiberglass insulation is an effective solution for homeowners on a budget. This type of insulation does not burn, meaning that it does not pose a fire risk. Some fiberglass insulation is made from recycled materials while they are not a tempting snack for insects and other attic pests. Finally, fiberglass can reduce sound.
One of the main disadvantages to fiberglass insulation is that it can be particularly dangerous to humans.

Fiberglass insulation usually comes with warnings stating that there may be carcinogens that can lodge in the lungs if they are inhaled. Some types of fiberglass insulation may even contain formaldehyde. Formaldehyde can cause cancer in those who are installing it. As such, protective gear must be used and it is not recommended that homeowners install this type of insulation on their own.
Another major downside to fiberglass insulation is that the insulation can settle over time. As the insulation settles, its "R" value decreases. Additionally, fiberglass batts do not seal walls and cannot be installed into small holes. This usually means that there are areas where hot or cold air can escape. If it is pushed into small spaces, it can cause moisture to build up. This in turn can cause mold to grow.
Although it may seem that there are more disadvantages than advantages to installing fiberglass insulation, this type of internal barrier material is still one of the top choices when a home needs insulation. A professional roofer can be contacted for help with choosing the right type of fiberglass insulation and for safely installing the insulation.
