Spray insulationand fiberglass are two types of insulation materials that are used commonly these days for insulating houses;it is often that many homeowners wonder which one is better, cheaper and a more practical solution for keeping their homes well-insulated. Read on and know the answer.

Spray Foam or Fiberglass Insulation – Which one is Cheaper?

When you pay for fiberglass insulation, you are supposed to make per-square foot payment. The expenses for fiberglass insulation of a home or room will be determined by the amount of space that you wish to insulate, as well as how much R-value you would like yourspray foam insulation material to come with.

On the other hand, you have to pay for Spray foam not by square foot but per board foot. A board foot happens to be a 1” thick by 1-foot long and wide space. For instance, when 3-inch closed cell spray foam is used to cover a thousand sq. ft space, it equals 3,000 board feet. The cost of 1 board foot of closed cell spray foam may be 2 – 3 times the cost of a sq. foot of fiberglass.

Which One is Better – Spray Foam or Fiberglass Insulation?

What is better spray foam insulation or fiberglass? With spray foam, although you have to pay a higher price, you can expect much better air sealing and insulation. While fiberglass insulation is much cheaper in comparison, its effectiveness is less, particularly in very cold weather conditions.

Fiberglass insulation is used in around 85% of homes in American, and happens to be the commonest type of home insulation. The market share of Spray foam insulation might be less in comparison, but it is getting more and more popular steadily. For spray foam insulation, there is a need for professional installation. However, homeowners themselves can also often install fiberglass insulation.

Spray Foam Vs Fiberglass Insulation – Which One Is Better Around Windows?

Spray foam Vs fiberglass insulation around windows, which one is better to opt for? This is a question that comes to the minds of many homeowners. It is important to note that a material which prevents the leakage of air around the frame is the best kind of insulation to use for stopping drafts around windows. 

Spray foam and fiberglass insulation are the two types of insulation materials that are used most commonly. Often, Spray foam comes as the better material for insulation around the windows. Fiberglass is only workable when the cavity is tightly air-sealed on every side of windows. Spray foam, on the other hand, itself works as an insulator and an air barrier.

Fiberglass insulation is durable, and can last quite a few years. But it can gradually lose its effectiveness by the end of its lifespan. As it deteriorates over time, this type of insulation has to be replaced. On the other hand, spray-foam insulation can last for as long as 8 decades or even more, justifying the higher price tag that it comes with.
