You’ve conquered the busiest season of the year, and now it’s time to tackle that insulation problem, so spray foam insulation or fiberglass insulation? Banker Insulation has previously written about the best applications for spray foam insulation, so let’s talk about the difference between these two popular, energy-efficient insulation types.

Spray Foam Insulation

The installation of spray foam is in attics, roofing, and interior wall cavities. Spray foam is used because it expands and fills even the smallest gaps. If combined with attic air sealing, spray foam becomes a moisture barrier reducing the risk of mildew or mold.

When combined with protective coatings and other materials during construction, spray foam can produce a cool roof. In an environment like Phoenix, cool roofs can reduce your overall cooling cost.

If you’re constructing a new home or you’re renovating, this is a perfect time to use spray foam insulation in your walls. This type of insulation can have benefits such as soundproofing, energy efficiency, and better comfort within your home.

Fiberglass Insulation

Fiberglass comes in the rolled form or loose fill that’s blown in. The loose type is used in areas such as attics, walls, and floors like spray foam. This type of insulation traps air in glass fibers that slows the transfer of heat into your home or business. Another benefit of fiberglass is that it’s low-cost insulation.

Fiberglass batts can be installed without professional assistance, but it’s highly recommended that you have a professional insulation company install it for you. Professionals will have all the proper protective gear, and there will be less of a risk to you and your family. Another benefit is that the installation cost is usually cheaper than spray foam.

Fiberglass has been around the longest, which is one reason that many people choose it over spray foam because it’s more familiar. Fiberglass also tends to make less of a mess than spray foam.

Cons of Spray Foam and Fiberglass

There are three cons that homeowners and business owners should be aware of when considering spray-in insulation: cost, difficulty to apply, and the mess. While the cost to install is a drawback, the amount of money you save in the long run makes up for this.

For fiberglass, there are two disadvantages you should be aware of: it’s not as efficient and settles faster. While you’ll probably save money on the installation, you’re more likely to have to install new insulation sooner, and you may not save as much on your utility bills.
