Windows are used in different settings and applications, each with unique needs and requirements. The single most effective way to increase the energy efficiency of a window is by adding more layers of glass between the inside and outside of your home.
## Double Pane vs Triple Pane Windows
The bottom line is this: **triple-pane windows are worth the additional cost** if you plan on living in your house for a long time, or if you can't tolerate a cold draft in winter. Triple pane is extra insurance against cold air seeping inside.
A **double-pane window** contains a sealed glass unit with two glass panes — infinitely more efficient than single-pane windows (where only one piece of glass separates you from the outside).
The best efficiency comes from **triple pane windows**, which use three panes of glass in a sealed unit.
## Noise Reduction
Triple pane windows also provide noticeably better noise insulation than their double-pane counterparts. If you live near a busy street, train tracks, or under a flight path, triple pane is worth strong consideration on those rooms alone.
## Cost Considerations
Ultimately, it comes down to what you're looking for from your windows. Triple-pane glass costs more, and you have to answer whether the higher cost is worth the increased benefits for your situation.
- **Primary residence in a cold climate?** The cost difference is usually worth it. - **Cottage, shed, or part-time residence?** Double-pane windows do the job at a lower cost.
