What Are Insulation Types?

If your home is starting to feel too hot in the summer or too cold in the winter, it may be due to the insulation in your home, especially if it’s over 20 years old and has never been updated.  There are several types of home insulation to choose from.  You’ll find the most common material found in insulation to be fiberglass, cellulose and rock wool.

The different types of insulation are Batts and blankets, loose fill, plastic foam, rigid boards and reflective each with their own advantages depending on your home.  The common standard by which insulation is measured is the R-value which measures the conductive resistance to heat flow and should be considered when choosing any material for insulation purposes.

What Is Blown In Cellulose Insulation?

Cellulose is made from a combination of treated recycled paper and wood made popular in the 1970’s when the green movement started.  Cellulose insulation provides an efficient green, non-toxic and affordable thermal solution to insulating your home. It is made of 80% post-consumer recycled newsprint.  Air leakage is the basic reason for heat loss and Cellulose is known to be a superb air blocker.

Blown in Cellulose insulation is sprayed and provides the extra benefit of soundproofing. A special blowing machine is used so it can be strategically applied throughout the structure. It can be installed in new or existing structures and is a popular retrofit application because existing wall finishes are not removed to install the insulation.  Cellulose provides and R-value of approximately R-3.5 per inch thickness. It is favored in attics because you can blow unrestricted depths of fiber to achieve deep coverage with very little labor.

The Cellulose Insulation Manufacturer’s Association (CIMA) claims that insulating a 1500 square foot house with Cellulose will recycle as much newspaper as an individual will consume over a 40 year period.  That means if all new homes were insulated with cellulose, this would remove 3.2 million tons of newsprint from the nation’s waste stream per year but only 10% of homes built today use cellulose. It is argued that long term, Fiberglass requires approximately 8 times more energy to make when adjusted to reflect energy cost per installed R-value unit.

What Is Blown In Fiberglass Insulation?

Fiberglass is the fluffy cotton candy like material that most people are familiar with made by jetting molten glass through tiny heated holes in a high speed stream.  The resulting fibers are drawn very thin and to great length.  The fibers are then collected into a matte to produce fiberglass insulation.

Like Cellulose insulation, it’s fire-resistant and won’t rot so it’s great for a wide range of homes. This material is the standard in over 90% of new homes built in the U.S.  Blown in Fiberglass insulation.  If applied to proper density, it will yield a similar performance to cellulose.  Densely blown, Fiberglass will have a slightly better R-value per inch although debatable based on which contractor you talk to.

Cellulose is slightly less in material cost, however, the cost of labor to install it is higher due to requiring far more bags to move and it’s sometimes dusty attributes.  So for reason of keeping labor costs down, Fiberglass is still usually favored by contractors and homeowners especially when moisture is not an issue such as in drier climates since it is not known to absorb moisture and hold it as well as Cellulose.

Special gloves and gear are recommended when applying Fiberglass insulation since the material is known to cause irritating skin conditions.  Professionals are well-protected and take extra precautions during the process of handling these materials.
