Choosing Between Insulation Types: Spray Foam vs. Fiberglass

Insulation plays an important role in homes and buildings. In fact, the EPA estimates that with the right insulation, energy bills could be decreased by up to 20%. This is why it’s crucial to make sure you’re using the right type of insulation for the job. There are two common types of insulation: spray foam and fiberglass. This article is going to explore a few key differences between fiberglass and spray foam insulation products so you can make an informed decision.

Fiberglass Insulation

Fiberglass insulation comes in big sheets. This type of insulation works by trapping air inside tiny glass fibers, which effectively slows the transfer of heat. In doing this, the material is able to keep heated or cooled air within a designated area. However, fiberglass insulation does not completely seal an area and still allows for air leakage, which could be problematic. In extremely cold weather, fiberglass loses heat pretty quickly, meaning it’s not as energy-efficient as it could be. So while fiberglass insulation is inexpensive, it isn’t often the best choice for buildings or homes that really need an energy-efficient type of insulation.

Spray Foam Insulation

Using spray foam insulation equipment is common among home builders, insulation contractors, and even HVAC contractors. This type of insulation works by starting out as a smaller amount of product and quickly expanding to almost 100 times the original volume. After the polymer is finished expanding and filling the designated area, it hardens. This allows the insulation to cover larger areas with less work. Because it turns into a solid, spray foam insulation products result in very minimal air leakage, making it very energy-efficient. Spray foam rigs are generally only used by professionals but the overall process is fairly quick. This insulation can last several years and effectively prevents both air and moisture infiltration. It can even help limit the amount of dust and pollen that enters a building.

As you can see, spray foam has endless benefits to offer. It can successfully prevent air leakage and even adds strength to the structure of a building. So if you’re looking for insulation for an upcoming project, consider going with spray foam insulation.
