The glass market is evolving rapidly, and a major innovation is shaking up the standards: vacuum double glazing. Thinner, lighter, and even more efficient than conventional double or triple glazing, it opens up new opportunities for architects, developers, and installers.
What is Vacuum Double Glazing?
Vacuum double glazing consists of two glass panes separated by an extremely thin gap (0.1 to 0.3 mm) from which air or gas has been removed. This vacuum space almost completely eliminates thermal transfer by conduction and convection.
- Total thickness: 6–12 mm (compared to 24–32 mm for standard argon double glazing and 36–44 mm for triple glazing).
- Weight per m²: around 20–25 kg/m² (30–40% lighter than traditional insulating glass).
Thermal Performance: Comparing Different Types of Glazing
One of the main advantages of vacuum double glazing is its exceptional energy performance.
Below is a comparative table of thermal transmittance coefficients (Ug, in W/m²·K):
Type of insulating glass | Average thickness | Average weight (kg/m²) | Ug (W/m².K) |
Argon double glazing | 24–32 mm | 30–35 | 1,1 – 1,3 |
Argon triple glazing | 36–44 mm | 40–50 | 0,6 – 0,8 |
Vacuum double glazing | 6–12 mm | 20–25 | 0,4 – 0,5 |
Result: with only 6–12 mm thickness, vacuum double glazing matches or even exceeds the thermal performance of triple glazing—while remaining much thinner and easier to handle. Acoustic performance is also significantly improved (gain of 4 dB).
The Advantages of Vacuum Double Glazing
1. Reduced weight for easier handling
Thanks to its thin profile and lighter weight, vacuum glazing is much easier to handle, reducing transport and installation costs as well as risks linked to heavy loads.
2. A modern and sleek aesthetic
With a thickness of only 6 to 12 mm, this glazing allows for slimmer frames, a more elegant design, and larger glass surfaces.
3. Outstanding thermal performance
With a Ug coefficient of 0.4 to 0.5, vacuum double glazing outperforms argon double glazing and matches—or even exceeds—triple glazing, while being two to three times thinner.
4. Enhanced acoustic insulation
The vacuum between the two panes effectively blocks sound transmission, delivering superior acoustic comfort, particularly suitable for urban environments and noisy areas
