R-values are additive, so any insulation you add to the outside of your house will improve its overall R-value—and a single inch of foam insulation can increase the R-value of your home by 5.

Foam board insulation is easy to use and a great DIY way to add some insulation. It comes in standard-size 4×8 sheets and smaller sizes, in thicknesses from 1/4-in. to two inches. Some types of ...

Its R-value averages R-4.3 per inch. With its relatively large air pockets, open-cell spray foam provides decent insulation against heat and noise. However, since the air bubbles are not sealed, both ...

offer higher R-values per inch than alternatives — potentially allowing for thinner insulation layers. Your roof insulation options are diverse — including spray foam, rigid boards ...

Higher insulation values come with fiberglass batts providing R-3 per inch of thickness, closed cell foam offering R-7 per inch, and blown cellulose yielding around R-3.85 per inch. 3. Air ...

Spray foam insulation is similar in application to ... it’s important to understand “R-value.” This is the standard by which all types of insulation are judged; the R-value essentially ...
