3 Types of Fiberglass Insulation

The type of insulation that is installed in your home can have a direct impact on your utility costs each month.

Good insulation prevents the transfer of heat from your home's interior to the outside environment, which reduces the amount of energy your HVAC system must use to keep your living space comfortable.

If you are thinking of fiberglass insulation installation, you will have three unique types of insulation to choose from. Learn more about these varieties to help you select the one that will work best for your home.

1. Roll Insulation

One of the most common types of fiberglass insulation is roll insulation. This product comes in long, rolled-up strips that are uniform in width. Homeowners who are retrofitting an existing space with new insulation will often choose roll insulation.

Roll insulation gives you the ability to customize the length of each fiberglass strip to meet the unique dimensions of your existing space. There is less waste with roll insulation, so you can keep the cost of your insulation installation as low as possible.

2. Batt Insulation

Batt insulation is similar to roll insulation. The major difference between the two is that batt insulation comes in pre-cut lengths. These pre-cut lengths can be great when insulating a new build or an addition to your home.

Less measuring and cutting is required when installing batt insulation than roll insulation.

The pre-cut lengths can easily be installed in spaces with uniform dimensions in a short period of time. Batt insulation installation costs can be low because of the reduced amount of labor required to complete each project.

3. Loose-Fill Insulation

The third type of fiberglass insulation that can be used for residential projects is loose-fill insulation. Unlike roll and batt insulation, loose-fill insulation does not come in strips. Instead, it consists of fluffy bits of loose fiberglass that are blown into place using a mechanical blower.

Loose-fill insulation is most commonly used to insulate attic floors. There are no seams where adjoining strips meet with loose-fill insulation, so there is less potential for air leakage when you choose this type of insulation for your home.

Loose-fill insulation can also be a great option for oddly-shaped spaces, as the fluffy bits of fiberglass can be pushed into any corner or crevice to create an airtight seal.

Your budget, the dimensions of your space, and your personal preferences will all play a factor in determining which type of fiberglass insulation will best meet your long-term needs.

Communicating With Your General Contractor

Nothing is more frustrating than deciding on a construction project, only to be bombarded by a long list of problems during the construction phase. Unfortunately, if you work with the wrong person, you might become pretty familiar with issues. About five years ago, I hired one of my neighbors to renovate my bathroom. Although the mere idea sounds ridiculous now, at the time it seemed like a natural solution to a real problem. Unfortunately, as soon as he got started, I knew that he didn't know what he was doing.
