Please try to solve this on a sheet of paper so it is easier to understand.
1). Compare the heat loss between a standard
double pane window 0.9 m by 0.47 m hat has a
gap filled with air that is 3 mm wide with a triple
pane windows of the same size that has two
gaps with air inside them, each 3 mm wide. The
outside temperature is 8° C and the inside
temperature is 25° C* for both situations. The
glass between the two gaps is 4 mm wide.

Since heat flow is measured in watts (J/s), a simple model emerges if you throw
in the obligatory substance-dependent constant k:
kA(T2 –
T1)
P =
d
