Is R60 attic insulation worth it?
Is R60 attic insulation worth it?
Recommended R-Value Varies by State You need exactly as much as the area you live in determines. Here, where temps get pretty hot for much of the year, attics should have from R30 to R60 (average is R38). Those living up north want anything from R49 to R60. This helps insulate against the extreme cold weather.
How many inches of blown insulation do I need for R60?
If you have no insulation, you’ll need 23″ to reach R-60.
What R-value insulation do I need for my attic?
R-38
The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.
What insulation is best for attic?
Fiberglass is one of the best attic insulation materials, and it’s available in various forms. We’ve already discussed the batts and roll forms, both of which involve flat, pre-cut sections. But fiberglass is also available in loose-fill or blown-in form.
How thick is R60 spray foam?
However it appears that it reaches it’s maximum R value at about 5-6 inches which equals approx. R30-36.

Can you add too much insulation attic?
It’s possible to over-insulate an attic as too much will cause moisture buildup and eventually result in mold. Eventually, adding more insulation leads to diminishing returns in trapping heat as well.
Which is better attic insulation blown or rolled?
The Differences Between Blown-in and Rolled Insulation The lower the R-value is, the less effective it will be as insulation – although it will be cheaper as well. In such situations, blown-in insulation is much more effective since it allows you to easily insulate those hard to reach areas.
How deep is R60 blown insulation?
It appears that 16″ deep is to get R60 for attic loose fill cellulose insulation, and 24″ deep is to get R60 for attic loose fill fibreglass insulation.
What is the best attic insulation?
Cellulose insulation is one of the most popular and efficient methods of attic insulation. It has a relatively high R value (3.7) and for the most part higher than that of fiberglass. Higher R values correspond to higher insulation power. In our opinion, it is the best bang for the buck.
What are value should attic insulation be?
Attic Insulation: Houses in a cold climate should have a minimum of R-49 in the attic, which is equivalent to approximately 16″ of fiberglass insulation. Warmer climates only require an R-38 or higher, or about 12″ or more.
