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.
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.

57% gain. A R30 would be the same as a R19 + a R11 batt.
You can put a higher "R" rated insulation batt in them, which will help keep the house cooler in the summer
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.
No, this statement is inaccurate. The higher the R-value of insulation, the more resistant it is to heat flow. R-value measures the effectiveness of insulation in resisting heat transfer, with higher values indicating better insulation properties.
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
To calculate the surface temperature on the cold side of 92mm of batt insulation, you can use the heat transfer equation, considering thermal resistance. First, determine the thermal resistance of the insulation using its R-value, which is typically provided by the manufacturer. Then, apply the formula (Q = \frac{\Delta T}{R}), where (Q) is the heat transfer rate, (\Delta T) is the temperature difference across the insulation, and (R) is the thermal resistance. Finally, rearrange the equation to solve for the surface temperature on the cold side, accounting for the indoor and outdoor temperatures.
The "r-value" is a measure of the thermal resistance of a material. However, cloth itself does not have a standard r-value as it can vary greatly depending on the type of cloth, its thickness, and other factors. It is generally better to refer to specific types of insulation materials for standardized r-values.
