According to the Department of Energy, properly insulating the attic can save 10 to 50 percent on a typical heating bill. For many homeowners, insulating the attic is the most effective method to save on energy costs.
How many inches of blown insulation do I need?
The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.
Can you put too much insulation in 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.

Is blown in insulation better than rolls?
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.
Which is better foam or blown insulation?
Between spray foam and blown-in cellulose, which is better? Both spray foam and blown-in cellulose insulation have their advantages. Spray foam has a higher R-value, so it’s the more effective insulator. But cellulose is better at insulating street noise.
How do I estimate the cost of insulation?

How many bags of blown in insulation will I need?
More on Calculating Insulation Needs Divide the measured square footage you obtained by 1,000 square feet to obtain the multiplication factor: 1,500 square feet/1,000 square feet = 1.5. Multiply the R-value chart number to obtain the number of bags (rounding up at the end): 40.8 * 1.5 = 61.2 or 62 bundles.
Which insulation is best for attic?
Many people consider fiberglass batt to be the best attic insulation. It consists of plastic reinforced by small glass fibers. The batt version comes in blanket form — i.e., small, pre-cut sections that you can lay down wherever you need to.
Is R38 attic insulation good?
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.
How often should attic insulation be replaced?
