The U value is the inverse of the R value. For R value 19 insulation the U value is 1/19, or 0.0526.
"r" you kidding?

Drywall provides an R-value of 0.32 for 3/8" board, 0.45 for 1/2" board, 0.56 for 5/8" and 0.83 for 1" board. In addition to increased R-value, thicker drywall has a higher STC.
The minimum data value in a data set is simply the lowest value of the set (easily found by arranging the set from lowest-highest values in an excel sheet or by hand).
R value of asbstos cment roofing sheet ?
The r-value of a sheet of newspaper is typically around 0.04 per inch thickness. This means that newspaper provides minimal insulation value compared to other building materials.
The r-value of a sheet of wax paper is generally very low, around 0.05 to 0.07. This means that wax paper is not an effective insulator and will not provide much thermal resistance.
That is the proper spelling of "cardboard" (the stiff brown corrugated paper material).
Corrugated Plastic
The R-value of steel sheet metal is relatively low, usually ranging from 0.02 to 0.04 per inch. This means that steel sheet metal is not a very effective insulator and does not provide much resistance to heat transfer. Additional insulation such as foam or other materials is typically needed to improve the thermal efficiency of structures made from steel sheet metal.
No
Yes, magnetic force can pass through cardboard since cardboard is not a magnetic material and does not block magnetic fields. The force will still act on any magnetic objects above or near the cardboard ramp.
No, cheetahs are obligate carnivores and must eat meat. Cardboard has no nutritional value.
