Are there temperature fall charts for various insulated rooms?

there 2 metrics may want consider:
r-value , u-value.

r value measure of how material insulates or reduces transfer of heat, , how insulation , building materials gauged.
u value measure of thermal conductivity or how material transfers heat, , typically how windows gauged.
these 2 values inverse functions of each other.

r values may added give total.
example if have 4" brick r value of 0.44 , 1/2 inch drywall gypsum board r value of 0.45 total r value of 0.89.

one way of checking how insulated room is, room steady temperature relative surroundings, switch off heat source, , measure rate @ temperature difference falls.

there charts available have done various types of insulated rooms?
