Is r-value good or bad?
it is a good thing i think R Value is the thermal resistance of a given material. The higher the R Value the more thermal resistance and the better the insulation. So, an R48 roof system is warmer than an R32 roof system. All insulation materials are rated by their R Value. An inch of rigid insulation has a higher R Value than an inch of fiberglass insulation. Check with the insulation manufacturer for the R Value.
An R-value is a rating for materials used as?
insulation
How much energy does insulation save?
it depends on the r-value of the insulation and the area or temperature range of the climate it is to be installed
What is the R value of attic insulation covered with plywood decking?
Every insulation has a different R value. It ultimately is determined by which insulation you will be using. Now lets do rough estimate. 4" thick, regular fiberglass mat has R-value of 13. Assuming that plywood has the same to half the insulating value of fiberglass, 1/2" plywood would have 1/8 to 1/16 of R-value of that 4" mat. Roughly R-1.6 to R-0.8
Do all materials have r value?
The answer depends on what you mean by "r values".
R -values of standard Batt insulation?
The R-value of standard Batt insulation typically ranges from R-3.1 to R-3.7 per inch of thickness. However, the actual R-value can vary based on the specific materials and thickness of the insulation.
Would batt be an form or type of insulation?
A batt is a form of insulation; instead of being a roll (as most insultion comes), a batt is usually a rectangular piece of insulation. A batt usually has a high R value and it is a lot thicker than most insulation so it is impractical to try to have it in rolls as they would be too large to handle easily.
What value does 10 insulation give?
If you are referring to the R value of insulation, then 10 would be the 'thermal resistance' value of the insulation. A value of 10 is about what 3 1/2 inches of fiberglass batt insulation would give you. That is what you might put within your exterior walls if you are using wood studs. The higher the R value the better insulation you will have. When you add up all of the R values of the materials that make up your exterior wall you will get your total value. Depending on where your building is located, and the climate in that area, you will need to adjust your insulation accordingly.
How do R-values of insulation affect the environment?

What is the difference in percent gain between R-19 and R-30 insulation in an attic?
57% gain. A R30 would be the same as a R19 + a R11 batt.
Why would 2x6 frame walls be good in Arizona?
You can put a higher "R" rated insulation batt in them, which will help keep the house cooler in the summer
Where can one find information on insulation r values?
One can find information on insulation R values via Wikipedia where there have a definition and a list of the types available. One can also find information on The Home Depot website.
How is insulation measured?
Floors, attics and walls all require insulation of different R-Values which are measured by the thickness of the insulation. The R-Value determines how well the insulation will resist heat flow. The higher the R-Value the more resistance it has to heat and cold. If you are adding to existing insulation there is another factor to consider. You will have to determine the R-Value of the existing to know how much additional insulation to add
What is the best type of attic insulation?
Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and its density. In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added.
What are value of insulation should you have in AZ?
in arizona according to the Department of Energy, they call for in an attic insulated home to have the equivalent of 16 inches to 18 inches of blown in attic insulation. Attic insulation is measured in R values regardless of what type of insulation you blow in or lay down. Attic guard is usually your best type of insulation which should be blown in at an R value of 49-60 in an Arizona home
Is dry wall an insulator?
While drywall, or gypsum board, does give insulation value it is not a high amount, a 1/2" piece of drywall will only raise the r-value by .45, if you are looking to improve the insulation of a wall you are much better off using rigid foam insulation. An extruded polystyrene board, that's Styrofoam, of 1" thickness gives you an R-value of 5.00, which is over 5 times greater per inch than that of drywall. You can further improve the insulation value of a wall by add some kind of batt insulation in-between the studs.
