Here’s Why You Should Use Spray Foam over Fiberglass
Trying to choose an insulation method? After comparing the two, spray foam is clearly the better option. Here’s why you should consider it.
Obviously, this depends on the type of spray foam or fiberglass, since some grades are better than others. However, looking at basic prices, it’s clear that fiberglass is cheaper than spray foam. At Home Depot you can get a roll of fiberglass with almost 50 square feet for $10, while spray foam can fill up that same space between $22 (open-cell) and $50 (closed-cell). But when you look at the pros and cons for each, it’s clear that forking over a few extra bills for some spray foam is going to be well worth the money.
What’s easier to install?
While fiberglass may be cheaper, spray foam tends to have an easier installation process. Fiberglass requires measuring and cutting to fit those wall spaces perfectly, while spray foam easily expands 100 times the original size after a quick spray. This means getting every small corner perfectly without having to cut up smaller pieces of fiberglass in order to fit everything. Not sure which spray foam to buy? Here are the top three spray foam insulation sprays you should consider using.
What’s better to have?
What lasts longer?
Spray foam. The spray foam will stay in place and doesn’t settle, which can ensure continual performance with little fear of damage. However, fiberglass will need inspection, and even sometimes will need an upgrade. Spray foam’s sealing qualities can even protect your home from dust, allergens, and pollutants, while fiberglass can get dusty and trigger allergy and respiratory issues.
