Insulation may be hidden behind the walls, but it plays a big role in keeping you comfortable all year long.
The job of insulation is to keep the house warm during the winter and cool during summer. With heating and cooling accounting for about half of the energy used in the home, proper insulation can cut back on energy usage and save homeowners money.
Keep reading for a comparison between two types of insulation: fiberglass and spray foam.
Fiberglass insulation is the more traditional form of insulation. This type of insulation comes in pre-cut rolls or blown-in loose fill. It works to regulate air temperature by trapping air inside tiny glass fibers, slowing the transfer of heat.
Pros of Fiberglass
Fiberglass insulation is inexpensive to install when compared to other types of insulation. It comes in pre-made R-Values, and it maintains performance levels for an extended period of time. Fiberglass is also easy to install.
Cons of Fiberglass
Though commonly used and easy to install, fiberglass is not as effective as spray foam at maintaining comfortable temperatures. Fiberglass cannot fit into every crevice, which can allow for air leaks. This is especially true in colder regions.
Spray foam insulation is newer than fiberglass and is becoming more popular in homes. Spray foam is installed by spraying a polyurethane foam into walls and ceilings. The foam expands to create an airtight seal. Spray foam can be used as the primary method of insulation or as a supplement to existing insulation.
Pros of Spray Foam
Since spray foam creates an airtight seal, it protects against pests, rodents, and mold, in addition to its insulating properties. It is more energy-efficient than fiberglass, sealing off any crevices so air cannot leak in. It also has a longer lifespan, because it does not break down or sag over time.
Cons of Spray Foam
Spray foam is more expensive than fiberglass. In addition, spray foam should be applied by a professional, which increases the cost even more. The installation process can be messy, so make sure you work with a professional who has experience with spray foam.
