An insulation value of R-38 is at the high end and requires a minimum thickness of 12 inches. R-value does not depend on a single layer of insulation. To achieve R-38, you can use two layers of R-19 or three layers of R-13, which give slightly higher thermal resistance.Is R38 better than r49?
A ceiling with an R-value of 38 lets through only 1/38 of the amount of energy per square foot that passes through that window, or about 2.6% of the energy; a ceiling with an R-value of 49 lets through only 1/49 of the amount of energy per square foot that passes through that window, or about 2.0 % of the energy.How thick is R38 Rockwool insulation?
x 15.5 in. x 48 in. Batts (41.33 sq ft/bag)What R-value should my attic have?
R-Value is a measure of insulation's ability to resist heat flow. 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.What R rated insulation should I use?
Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy's (DOE) ranges for recommended levels of insulation below.Is R38 good for attic?
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. The more insulation you use, the better insulated your home will be.What insulation is best for attic?
Fiberglass, cotton, and mineral wool can all work as loose-fill insulation material, but the far and away top choice for blown-in insulation is fiberglass. Contrary to batts insulation, blown-in fiberglass insulation is perfect for filling in tight voids around wiring, pipes, or any area with awkward framing.What is recommended R-value for ceiling?
For homes in California, the attic should achieve an R-value between R-30 and R-60. Most areas of the country have a higher minimum R-value recommendation, but just about everywhere recommends up to R-60.Is r40 insulation good?
It is a rigid material that helps reject lots of water, adds wall racking strength as well as impact resistance. Closed-cell foam has a higher R-Value than any insulation, it ranges from 5.0 to 7.0 per inch. Regarding the thickness of the spray foam insulation, it depends on certain factors.Is R30 enough insulation for attic?
The average recommended level is 14 inches of R49. In Zone 2, the average minimum requirement for attic insulation is 9 inches of R30 fill. The average recommended level is 17 inches of R60. In Zone 3, the average minimum requirement for attic insulation is 9 inches of R30 fill.Can insulation be thicker than joists?
For the most effective results, insulation that is thicker than the depth of the ceiling joists should consist of two or more layers. The thickness of strips making up the first layer should equal or exceed the width of the ceiling joists.What insulation fits in 2x10 rafters?
Consider using high-density R-30 batts, which are as thick as R-25 batts, but fit into 2x10 framing. You can also add rigid foam insulation under the rafters, which adds R-value and eliminates thermal bridging through wood rafters.How much does blown attic insulation cost?
In general, it costs between $1 and $1.50 per square foot to insulate an attic with blown-in insulation, so a 1,200-square-foot attic would run $1,200 to $1,800 to insulate.How much insulation do I need for 1000 square feet?

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.Does doubling the insulation increase the R-value?
ABOUT INSULATIONThe thermal barrier of a home should consist of a continuous layer of insulation on all sides—including the lowest floor, the exterior walls, and the ceiling or roof. Doubling the thickness of insulation will double the insulation's R-value, cutting heat loss in half.
