Why are double-glazed windows effective at reducing thermal energy transfer?
1 )
They contain a vacuum between the glass panes.
2 )
The two layers of glass prevent conduction.
The argon gas between the panes is a poor conductor, and the space prevents con vection currents.
4 )
They reflect all radiation away from the building.
