Most Widely Used
Fiberglass insulation is the most often used of the various types of home insulation. It’s available in batt, blanket, and blown-in forms.
This type of insulation is made of mostly natural ingredients: sand and recycled glass. These materials are melted and spun into strands called fiberglass.
Fiberglass insulation is considered a “green” product because its use decreases the amount of energy required to heat or cool your home. This will cause less burning of fossil fuels and less emissions from this burning. But the high temperatures (around 2500 degrees Fahrenheit) needed to manufacture the fiberglass makes the process very energy intensive.
Because of this need for more energy in its manufacture, fiberglass can be seen as less desirable than cellulose, which is its nearest competitor. But blown-in fiberglass has about the same R-value as cellulose, giving you the same value for your money.
Advantages of Fiberglass Insulation
Loose fill fiberglass that is blown in can be an alternative to cellulose insulation, in spite of a higher cost. When fiberglass is blown in, it expands to fill all of the space where it’s used. This leads to an airtight home.
Because this type of fiberglass is made of virgin materials, there are no chemicals added to the product. This makes it a good insulation to use when people in the home have allergies.
There will be little or no settling or deterioration with blown-in fiberglass. Animals and microscopic organisms won’t use it for food.
Application of Blown-In Fiberglass
Since blown-in fiberglass is made of small strands of the material, it is considered a carcinogen. This means special precautions must be used when applying the insulation, including masks and body covering to protect those workers applying it. Once the fiberglass insulation is in place, it is covered with an appropriate material to keep the fibers from invading the living spaces. When blown-in fiberglass is used in spaces like attics where it usually won’t be disturbed, it is safe for the occupants’ health.
Professionals are usually best for applying this insulation material.
