0it 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.

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.

The answer will depend on the value of r.The answer will depend on the value of r.The answer will depend on the value of r.The answer will depend on the value of r.

The required R value for walls and roof insulation varies depending on your local building authority. The ideal R value will depend on the climate, altitude, latitude and exposure of your site and the form, amount of glazing,materials and use of the building.

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.

why semi conductive materials do not conduct current well & all of little value in their intrinsic state

No. A higher R-value is a better insulator.

To convert U vals To R Vals 1/u = r val

Yes. Don't know for sure but its pretty low. however note that R value depends on the thickness. You double the thickness you double the R value.

the r value of air is pretty high
