In this article, we’ll look at the pros and cons of home insulation foam vs fiberglass. Fiberglass is a cheaper and more practical option, and spray foam is more durable and easy to install. But there are a few important differences between the two materials. Here are some of the key differences between the two:
Open cell spray foam has a lower R-value
The R-value of home insulation measures its resistance to heat transfer. The higher the R-value, the more effectively it holds in heat and air conditioning. The higher the R-value, the better the insulation will keep the interior of a home warm during the winter and cool during the summer. Fiberglass and Open Cell spray foam have similar R-values, but the latter has a lower thickness.
Fiberglass insulation is cheaper
Homeowners can opt for fiberglass insulation over home-insulation foam, but there are some disadvantages to this material. First of all, fiberglass sags into the walls, causing uneven thermal insulation. Second, fiberglass is prone to mold and mildew growth, and it can be harmful to workers without protective gear. Finally, fiberglass can be extremely expensive to install, and it will require special training and a spray foam rig that costs upwards of $70,000.
Spray foam is easier to install
Installing spray foam insulation is easier than ever. You can add it to existing walls without any drywall removal. Just remember that spray foam expands rapidly. If it doesn’t cover the whole panel, it will cause excess pressure against the plasterboard, cracking it. You may have to spend extra money to cover this problem, so it’s best to hire a professional. The best way to find the right expert in your area is to ask them to come out and give you a free estimate. Read more about this topic here.
Spray foam is waterproof
Despite its waterproof properties, spray insulation foam is not a perfect substitute for closed-cell insulation. It may be less dense, but it adds a substantial layer of insulating value that will not waver when temperatures fluctuate outdoors. However, it must meet certain structural requirements. A main flaw of this material is its inability to hold insulation as tightly as its closed-cell counterpart. It also has lower R-value, which measures its resistance to heat flow.
Fiberglass insulation is unfaced
There are two basic types of fiberglass insulation: faced and unfaced. Compared to faced fiberglass insulation, unfaced is softer, but both types can work as effective insulators. A face is made of fiberglass that is exposed to the elements, while an unfaced version is made of fiberglass that has not been treated with face-to-face adhesive. Unfaced fiberglass insulation can be easily installed and has a smooth surface. Learn more here.
