Glass! Changing the Perception.
Jaipur Tuff's Vacuum Insulated Glass (VIG) replaces the air gap in ordinary windows with a true vacuum — thinner than a standard double‑glazed unit, yet built to lower your energy bills, block outside noise, and stop your windows from fogging up.
Heat travels through a window in three ways. VIG is engineered to shut down two of them completely — which is why it performs so differently from ordinary double glazing.
In a normal window, heat creeps directly through the gas trapped between panes. With no gas left to carry it, that path disappears almost entirely.
Warm and cool air currents that normally circulate inside a sealed window simply can't form in a vacuum — there's no air left to move.
An optional low‑emissivity coating reflects radiant heat back to its source, so summer sun and winter cold both have a harder time getting through.
Every number on a glass data sheet maps to something you actually feel at home or at work — here's what it means for you.
A vacuum core keeps indoor heat in during winter and outdoor heat out during summer, easing the load on your AC and heater year‑round.
U-value ≈ 0.5 W/m²KTraffic, construction, and noisy neighbours lose most of their punch — the vacuum gap has almost nothing to carry sound waves through.
Up to 38 STC / 31 OITCOur anti‑condensation series keeps the inner glass surface warmer, so moisture doesn't settle, drip, or invite mould on cold mornings.
Warmer surface, drier sillAt roughly a third of the thickness of a triple‑glazed unit, VIG fits into existing frames — ideal for renovations and heritage buildings.
~40% lighter than double glazingEvery pane is tempered before assembly — up to four times stronger than regular glass, and it breaks into small, blunt pieces rather than shards.
Tempered on both panesLower energy use over the life of the building means a smaller running carbon footprint — and less material used per unit than a triple‑glazed window.
Lower embodied + operational carbonEvery Jaipur Tuff VIG unit shares the same vacuum core — we simply tune the coatings and glass make‑up to whichever benefit matters most to your project.
Paired with a low‑emissivity coating, this is our best‑performing series for climate control — ideal for homes and offices that run air‑conditioning or heating for most of the year.
| Parameter | Value |
|---|---|
| U-value (thermal transmittance) | 0.4 – 0.6 W/m²K |
| Solar Heat Gain Coefficient (SHGC) | 0.28 – 0.55 |
| Visible Light Transmission | up to 80% |
| Overall unit thickness | 6 – 8 mm |
Lower U-value = less heat passing through the glass. Values vary with coating and glass thickness selected.
The vacuum gap starves sound waves of a medium to travel through, giving this series noticeably better acoustic performance than standard double glazing — without adding bulky thickness.
| Parameter | Value |
|---|---|
| Sound Transmission Class (STC) | 35 (standard) / 38 (hybrid) |
| Outdoor‑Indoor Transmission Class (OITC) | 30 (standard) / 31 (hybrid) |
| vs. standard double‑pane IGU | 34 STC / 29 OITC |
| Overall unit thickness | 6.5 – 10 mm |
Higher STC/OITC numbers mean more sound is blocked. Hybrid VIG combines a vacuum pane with a conventional gas‑filled gap for maximum reduction.
Condensation forms when a cold glass surface meets warm, moist indoor air. By keeping the inner pane closer to room temperature, this series keeps that surface above the dew point far more often.
| Parameter | Value |
|---|---|
| Interior surface temperature lift | up to +6 – 8°C vs single glazing |
| Recommended for exterior temperatures down to | -10°C |
| Indoor relative humidity tolerance | up to 60% RH |
| Overall unit thickness | 6 – 8 mm |
A warmer interior glass surface is the single biggest factor in preventing condensation — figures are indicative and vary by site conditions.

| Parameter | Single Glass | Standard Double Glazing | Jaipur Tuff VIG |
|---|---|---|---|
| Overall thickness | 4 – 6 mm | ~24 mm (4‑16‑4) | 6 – 8 mm |
| U-value (W/m²K) | ~5.8 | ~2.7 | ~0.5 |
| Sound rating (STC) | ~28 | ~34 | 35 – 38 |
| Relative weight | Lightest | Heaviest | ~40% lighter than double |
| Visible light transmission | ~88% | ~80% | up to 80% |
Its slim profile means VIG goes where thicker insulated units simply can't fit.
