Is triple glazing worth the upgrade?

Triple glass costs more, but often improves comfort near the window in winter and can help with noise or exposed orientations. It is not magic: the frame and installation matter too.

And double 6 mm + 4 mm?

If noise is the main issue, a 6 mm + 4 mm double often beats a standard triple. Thermally, triple usually still leads. We choose based on priority: winter comfort, bill, or a busy street.

When double still makes sense

Seldom-used rooms, a tight budget, or configurations that already perform well as Low-E/argon double glazing. We sometimes prioritize triple (or 6+4) where you live (living room, bedrooms) rather than everywhere by default.
