What is the are rating of insulation?
Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.
What is the your value of wall insulation?
The R value is, in essence, the measurement of an insulation sheet’s ability to resist heat flow. Basically, R values range from 1.5 to 7, and the higher the number is, the more effective the insulation sheet is at increasing thermal efficiency, and thereby, insulating your home.

Is R60 too much insulation?
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 equals R60?
If you have approximately 6" of existing insulation, you'll need to add an additional 17" to reach R-60. If you have approximately 10" of existing insulation, you'll need to add an additional 13" to reach R-60. If you have no insulation, you'll need 23" to reach R-60.

Can you put too much insulation in your 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 R49 insulation good for attic?
It doesn't matter if your attic roof is low-pitched, dark colored, poorly ventilated, with full sunshine. R-49 will do a good job of protecting your ceilings from the extreme inferno-like temperatures of 130-140 degrees in your attic. Think about it.
How thick should blown-in attic insulation be?
about 10 to 14 inchesThe recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.
What is a good R-value for exterior walls?
R-13 to R-23Typical 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.
How thick should insulation be in walls?
In the walls: Typically, there is not an abundance of space inside your walls, so packing in the insulation isn't a bad idea. To get an R-value of 13 to 16, you will need four to five inches of insulation. However, if you use a more effective type of insulation, you may be able to get away with less.
What is the R-value of IsoBoard?
The Thermal Conductivity (k value) of new IsoBoard is 0.024W/m°C, and that of 5-year aged IsoBoard at 90% relative humidity is 0.03W/m°C, which is referred to as the “long term design” value.
How many inches is R60 cellulose?
17 inchesThe average recommended level is 17 inches of R60. In Zone 3, the average minimum requirement for attic insulation is 9 inches of R30 fill. The average recommended level is 17 inches of R60.
How deep is R60 cellulose?
In temperate coastal areas such as Zone 3, attic insulation of at least R30 up to a maximum of R60 is recommended. For loose-fill cellulose, this translates to a total depth ranging from 8 inches up to 16 inches.
How thick is r49 batt?
14" thickA: Hello Shelly, Owens Corning R-49 Fiberglas Batt Insulation is 14" thick and will be compressed if installed into a 2x10 or 2x12 rafter. Compressing insulation will reduce the R-value of the product.
What does R 60 insulation mean?
Related to: General. “R” is referring to R-Value. An R-Value is given to a product to indicate the ability for the insulation to resist heat flow. The higher the R the better the resistance to heat flow in most cases.
What is the recommended initial depth for R60?
Cellulose would perform at ~R60 at settled depth of 16-16.5", but the initial depth has to allow for ~10-15% of settling, ergo 18-20". The 20" number the recommended initial depth for R60 some of the better fiberglass blowing wools too.

Loose fill cellulous has an R-value of 3.7/inch so you'll need approx. 17" to hit R-60
How Thick Is R-19 Insulation?
R-19 fiberglass batting is usually around 6.25″ thick, but this can vary depending on the insulation material used.
What Is R-19 Insulation Used For?
R-19 is viable in several places around a house. Here are some common areas people consider putting it.
How Good Is R-19 Insulation?
R-19 is a good amount of insulation for exterior walls across the country. Depending where you live, there may be better options, however.
How thick is R49 insulation?
Like I said before, this insulation material needs the least thickness to achieve R49. This is due to the closely packed, air-tight structure of this insulation material. The R-value of closed-cell spray foam is around 6.5 per inch of its thickness. Therefore, closed cell spray foam insulation needs to be 7 to 8 inches thick to achieve R49 insulation rating (49/6=7.537 inches).
What is the R value of an insulating material?
The R value of an insulating material is basically the temperature difference needed between its two sides to conduct 1 BTU of heat per hour through an area of one square foot per inch thickness.
How much insulation is needed for fiberglass insulation?
As a result, blown-in fiberglass insulation has an R value of 3.2 only. Therefore, it needs to be at least 16.25 inches to R49 insulation.
Why is closed cell foam insulation good?
For example, closed cell foam insulations are a good choice if your attic or walls do not have room for thicker insulations.
What is R49 insulation used for?
Due to their high resistance to heat conduction, R49 insulations are used in attics irrespective of what climate zone the houses are in. However, they are more widely used in US climate zones 5 to 8.
What is the R value of foam board?
With an R-value of 5 per inch, foam board or polystyrene can achieve R49 insulation with 10-inch thickness.
What is the advantage of spray foam?
The advantage of open-cell spray foam is that it is more flexible, so this can be used in places like ceilings and roofs. Also, because there is no tightness between the individual cells, it does not require any special tools to install.
