Insulation Comparison, which is best?

When it comes time to insulate your home, you have many insulation options at your disposal. All insulation is designed to make your home more comfortable and efficient, but not all insulation is made equal. So how do you choose which insulation is right for you? The experts at 360 Thermal have come up with this insulation comparison to help you choose between the three main types of insulation: fiberglass, cellulose and spray foam.


Fiberglass is pink and fluffy, and it comes in batts. Fiberglass is also the most common types of insulation because it’s cheap and easy to install the pre-cut batts. But there are drawbacks to fiberglass insulation as well. Of the three types of insulation we’re going over today, fiberglass has the lowest R-value. And since fiberglass comes in batts, it makes it difficult to insulate nooks and crannies. Fiberglass also becomes useless once it gets wet.


Cellulose insulation is made of pulverized cloth and paper that has been treated with fire retardant, and it is a loose-fill product. Cellulose has a slightly better R-value than fiberglass, and since it’s loose, it can be blown into any nook or cranny. Cellulose helps to seal air leaks, and it even has some sound-proofing abilities. The downside to cellulose is that, if it gets wet from a roof or plumbing leak, it won’t dry quickly and will likely lead to mold.

Spray Foam

Spray foam is made by mixing liquid chemical compounds, and it can be used to fill any crack or gap. Spray foam has a much higher R-value than either fiberglass or cellulose, and it offers superior soundproofing qualities. Spray foam is also impermeable to water, so you don’t have to worry about mold or mildew.

Cutting your Utility Bills with Spray Foam Insulation

As you can see, spray foam insulation is clearly the superior choice, and here at 360 Thermal, we are your go-to spray foam experts in Houston. Contact us today to get your free estimate.
