In [7]:
price of insulation = 0.3275 dollar / foot ** 2
total cost of insulation = 3094.875 dollar
UA value = 50.09276437847866 btu / delta_degF / hour
Yearly energy cost = 36.06679035250464 thm
Yearly insulation cost = 309.4875 dollar
We compare to the cost of one sheet of insulation to multiple sheets.
1 sheet cost is $44 per year and 250 therms burned
