Question 1

Is double glazing worth it in Indian weather?

Accepted Answer

Yes, particularly in cities with strong summer heat, high humidity and traffic noise which describes most urban Indian markets. The hotter and noisier your specific location, the stronger the case.

Question 2

How much do double glazed windows cost compared to single glazed?

Accepted Answer

Expect roughly 30–60% more upfront than single glazing, depending on frame material, glass specification and gas fill. The difference is typically offset over time through lower cooling costs, though the payback period varies by home and climate. Premium brands like TOSTEM, which deliver factory-engineered systems, often sit at the higher end of this range but offset the upfront cost with superior seal reliability and durability through TEXGUARD-coated aluminium frames, reducing long-term replacement costs.

Question 3

Do double-glazed windows really reduce electricity bills?

Accepted Answer

In most homes, yes. By slowing heat transfer through the glass, they reduce how hard your air conditioner has to work, which lowers electricity consumption. The effect is most noticeable in rooms with large glazed areas and direct sun exposure. Optimised double-glazed systems, like TOSTEM's pre-tested aluminium units with low-E coatings, maximise this benefit because factory quality control ensures consistent gas fills and seal integrity that preserve thermal performance year over year.

Question 4

Can double glazed windows be repaired if the seal fails?

Accepted Answer

Not pane-by-pane. If the seal between the two panes fails and moisture or fogging appears, you usually need to replace the entire glazed unit. TOSTEM aluminium System Windows use a pre-engineered system that helps reduce the risk of issues caused by inconsistent on-site assembly. This is why seal quality and warranty terms matter more than almost any other spec when buying—and why choosing a manufacturer that factory-builds and tests complete units (rather than local assembly) meaningfully lowers the likelihood of early seal failure.

Question 5

Are double glazed windows only suitable for modern or luxury homes?

Accepted Answer

No. While slim modern double glazed windows suit contemporary architecture particularly well, the underlying thermal and acoustic benefits apply to any home with meaningful sun or noise exposure, regardless of budget tier.

Question 6

What’s the difference between double glazed windows and double glazed windows and doors as a system?

Accepted Answer

The glazing technology is identical to two sealed panes with an insulating gap. “Windows and doors” simply refers to using the same double-glazed glass and frame system across sliding doors, casement windows and fixed panels on one facade, so the whole home gets consistent thermal and acoustic performance rather than just individual windows.
