Double Glazed Window Cost in India (2026 DGU Price Guide)

Is Double Glazing Worth It in India? The Honest Answer

Double glazed windows cost 60-80% more than single glazed. But in an air-conditioned building, single glazing costs you more in electricity every year. The question isn't whether DGU is expensive — it's whether the payback period makes sense. In most Indian commercial applications, it does.
