As insulation specialists, it’s no surprise that we get a lot of questions from homeowners about insulation. “What are the different types of insulation?” “What kind of insulation is best for my home?” “Are there types of insulation I should avoid?”
Home insulation is especially important here in New England where winters are frigid. We wanted to take a moment to give you an overview of the different types of insulation and which types offer the greatest benefits.
How Insulation Effectiveness Is Measured
Before we introduce you to the most effective types of insulation, it’s important to understandR-value. R-value measures insulation’s ability to control heat flow. The higher the R-value, the greater the insulating power.
Different types of insulation have different R-values. Cellulose insulation, for example, has an R-value of R3.2 to R3.7 per inch in loose fill form. If you wanted to achieve an R-value of, say, R49 in the attic using cellulose, you would need to install enough of it (about 14 to 16 inches) to achieve that R-value.
The Most Effective Types of Insulation
Cellulose insulation is made from recycled newspaper and treated for fire resistance, making it eco friendly. It comes in a loose form, allowing it to be blown into finished areas and hard to reach spaces. It may be used in a loose fill, such as when it’s blown along an a ttic floor, or densely packed in building cavities.
Spray foam insulation is sprayed on a surface as a liquid and then quickly expands into a foam plastic to fill every hole and crack. Because of this, it has excellent air sealing qualities and can even serve as a vapor barrier. Spray foam is great for air leaks, high moisture areas, and hard to reach spaces.
|Type of Insulation||R-Value Per Inch||Great For|
|Cellulose, loose fill||R3.2-R3.9||Attics|
|Cellulose, densely packed||R3.8-R3.9||Walls|
|Spray foam, open cell||R3.5-R3.6||Air leaks, walls, ceilings, floors, areas that need soundproofing|
|Spray foam, closed cell||R6.0-R6.5||Air leaks, walls, ceilings, floors, crawlspaces, high moisture areas|
