Fiberglass vs Cellulose vs Foam Insulation

You know your home needs to be insulated, but with so many types of insulation to choose from, which one should you go with? Your local experts at Foam Bear Tampa are here to explain the differences between fiberglass, cellulose, and spray foam insulation so you can choose the best option for you and your home.

Fiberglass: The Traditional Option

Whenever you buy a new home, it likely has fiberglass insulation. This is because it’s the less expensive choice while still technically getting the job done, but that doesn’t necessarily mean it’s the best option. Since fiberglass insulation typically consists of whole sheets placed side-by-side, it’s difficult to get an air-tight seal since there will likely be gaps in-between where the sheets meet. Fiberglass is the cause of many common problems due to poor insulation. Another thing to consider is that fiberglass insulation needs to be maintained and replaced every so often since it wears down faster. So although it may seem cost-effective at the moment, you’ll be paying more with each new replacement.



● Cheap

● Poor insulator

● High energy bills

● A hassle to install

● Maintenance required

● Needs replacement every few years

Cellulose: An Older Invention

For those who are looking for a quick and easy solution, cellulose insulation consists of loose fill or blown-in materials often including recycled newspaper. While this will technically fill in the space that you need insulated, it’s not effective in the slightest since air can easily flow through the many gaps in the loose composition. Your air conditioner will be on full blast as if there’s no insulation at all. And although it’s a less expensive option like fiberglass, you’ll be paying for frequent upkeep and replacement costs. The first application is usually the easiest since you’re just filling in the space, but removing your old cellulose insulation to make room for a new application can leave a huge mess behind. It’s no wonder that it hasn’t been a popular choice since the ‘50s.



● Cheap

● Easy first application

● Minimal insulation

● High energy bills

● Needs to be replaced often

● Leaves a huge mess

Spray Foam: The Best All-Around

If you’re unfamiliar with spray foam insulation, it’s a mixed compound that expands after it’s applied. This trait, when handled properly, can provide a completely air-tight seal for the most comfortable home and lower energy bills. This is because, on top of providing a tight seal, spray foam has the highest R-value meaning that it works best as an insulator. Not only that, but properly-installed spray foam insulation can last a literal lifetime with no maintenance required. This is why spray foam is the best choice for homes.



● Best insulator

● Low energy bills

● No maintenance or replacements needed

● Lasts a lifetime

● Quick installation

● Higher initial cost
