Question

Consider a double pane window. The glass surface may be treated with a low emissivity coating to reduce ________?

1) heat transfer
2) light transmission
3) sound insulation
4) condensation

Answer 1

A low emissivity coating on the glass surface of a double pane window reduces heat transfer, helping to keep the room warmer and reducing heating costs.

Step-by-step explanation:

A low emissivity coating on the glass surface of a double pane window reduces heat transfer. This coating reflects heat back into the room, preventing it from escaping through the window. By reducing heat transfer, the low emissivity coating helps to keep the room warmer in colder months and reduces the need for heating, ultimately saving energy and reducing heating costs.
