Side by side
Pick the criteria that actually matter for your house and exposures.
- Cost: triple pane typically adds 10–25 percent per opening
- Comfort: triple pane reduces the cold-glass feeling on windward elevations
- Noise: helps, but laminated glass in a double pane often does more per dollar
- Weight: heavier sash, which matters on large or upper-floor openings
- Efficiency: the low-E coating and a tight install usually matter more than pane count

- Balanced low-E coating, low U-factor with a moderate SHGC

Frequently asked questions
How long should replacement windows last?+
A quality vinyl or fiberglass unit installed correctly should run 20 to 30 years, with the insulated glass seal typically being the first thing to fail. Builder-grade units in newer subdivisions often start fogging at the 12 to 18 year mark.
What is the best upgrade if I skip triple pane?+
A better low-E package matched to your exposures, laminated glass on street-facing rooms for noise, and a full-frame install with proper flashing and perimeter air sealing.
