yes the R-value does indicate resistance to heat flow
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.
The Potential energy decreases as r increases.
No. If you can get it, vacuum is the best insulator.
The actual bodywork of a box trailer is normally a thin skin of aluminum with a wooden/steel support frame, sometimes with a fibreglass roof. the cab itself can be steel or fibreglass.
glass you can see through and fibreglass you can not
no
all i know is fibreglass is on boats pools are made of it and fibreglass is a fibre
One of the companies that manufacture fibreglass ponds is actually Fibreglass-Ponds in the United Kingdom. You can order from their official website as well as contact them over the phone.
maybe

The U value is the inverse of the R value. For R value 19 insulation the U value is 1/19, or 0.0526.
hold r
the r value of air is pretty high
