How much heat is lost through a 3’× 5' single-pane window with a storm that is exposed to a 60°F temperature differential?

Step 1

Heat lost *Q* is the product of *U*-value, temperature difference ∆*T* and area *A*. Therefore,

Step 2

*R*-value of single pane window with a storm is equal to 2. Therefore, *U-*value whi...
