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
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
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 a bale of straw?
Regular straw would not be safe to use as insulation. . .there are places that sell treated straw though, and they would have to tell you the r-value
U value of r-19 insulation?
The U value is the inverse of the R value. For R value 19 insulation the U value is 1/19, or 0.0526.

Which material has the highest r value stucco pine board concrete or fiber glass insulation?
Fiberglass Insulation, R Value of 3.14. Pine board has an R Value of 1.74
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 does an R-Value tell you?
It is the measure of insulation against heat/cold afforded by varying thicknesses and composition of construction insulation materials. The higher the "R" Value the better the insulation characteristics.
Where did the name r value come from in insulation?
Where does the R value, respiratory quotient or RER come from.

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.
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.
