Triple glazing adds a third pane and a second gap. It's common in cold European climates, but the calculation is different here. Here's how to think about it for an Indian home.
A third pane and second air gap further slow heat transfer and add more sound dampening than double glazing. The gains over double glazing are real but smaller than the jump from single to double.
Triple glazing is designed mainly to retain indoor heat in very cold winters — a problem most of India does not have. For heat exclusion and noise, well-specified double glazing already does most of the work here.
For the great majority of homes in this region, good double glazing is the sensible stopping point. Triple glazing is rarely necessary and adds weight and cost for a marginal local benefit.
Rarely. Triple glazing mainly helps retain heat in very cold climates. For heat exclusion and noise here, good double glazing is usually the right level.
It adds some noise reduction, but the bigger improvement is going from single to double. The double-to-triple gain is smaller.
