What is the R rating of a double pane window?

3 to 3.8
Double-pane windows have an R-value ranging from 3 to 3.8, while triple-paned windows have an R-value of up to 7- 8, making them more effective at blocking heat flow. This means that replacing double-paned units with triple-paned windows reduces heating costs.

How much does double insulated glass cost?
