A Comparison of Heat Flux Through Double- and Single-
Paned Windows

Our Experiment:• Using a hairdryer, we heated up one side
of a single-paned window• Both of the surface temperatures were
measured using a thermocouple every few seconds until they reached equilibrium temperatures

Our Experiment – continued. . .• This same procedure
was repeated for a double-paned window
• The temperature data obtained was used to compute the heat flux through the two different windows and a ratio was found between the two

Discussion of Results
• It is clear from the preceding slides that double pane windows are far more thermally efficient than single pane windows.

Conclusions and Recommendations
Buy new windows!
