Which keeps more heat fleece or soft leather?
The answer depends on air flow and if it's wet. Fleece has a higher R value, however it won't stop air flow by itself. Leather will stop air flow, however it does not have a very high 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.
The effectiveness of insulation is rated with?
The effectiveness of insulation is rated with an R-value. The higher the R-value, the better the insulation's ability to resist heat flow.
Is a material with a lower R-value a better insulator than a material with a high R-value?
No. A higher R-value is a better insulator.
What type of insulation has the highest R value?
As strange as it may sound dead or still air is one of the best insulators. Insulation such as fiberglass or rock wool and styrofoam work because they are fluffy with trapped air. If you have a sheet of four inch thick R40 fiberglass and squeeze it into a wall made of 2X3 studs you will have less R value than than a 3 inch piece of fiberglass insulation. So the highest R value goes to the insulation that traps the most dead air per inch of thickness and is installed propperly.

Why is old putty good for insulation?
I am not sure where you heard this but the thickness of old putty against the thickness of insulation for r-value is not as good. The best insulator is air. Fiberglass insulation has a high r-value because of the air it holds not the fiberglass itself. So that's why you don't cram 6in fiberglass into a 4in space, it does not work when you compress it.
