This is one of the questions we hear most often.
“Why your vacuum insulated glass cost way more than standard insulated glass?”
We do not avoid the question. Once you understand SuperVIG®’s value, we believe you will see whether it is worth it for you.
How does it work?
Vacuum insulated glass is one of the most complex glass products used in buildings today.
It takes far more than simply joining two panes of glass.
What Makes SuperVIG® VIG Different?
Difference 1: Precise Support Pillar Placement
Because the space inside vacuum insulating glass is evacuated, the two panes must withstand enormous atmospheric pressure—about 10 tonnes per square metre.
To prevent the glass from breaking under this pressure, thousands of microscopic support pillars must be evenly distributed between the panes.
These support pillars must meet strict requirements:
Only about 0.5 mm in diameter
Height tolerance controlled at the micron level
Precisely calculated spacing to distribute pressure evenly
Resistant to high temperatures and corrosion, with extremely low thermal conductivity
Failure in a support pillar can cause the entire glazing to be void.
Difference 2: Our Patented Proprietary Edge-Sealing Method
Edge sealing is the most critical technical challenge in vacuum insulated glass.
SuperVIG® uses a patented edge-sealing material system that must provide:
- Hermetic Seals:Minimal gas leakage
- Thermal expansion compatibility:Closely matched thermal expansion to the glass to prevent cracking through repeated temperature cycles
- High-temperature resistance:Able to withstand the heat required during edge sealing
- Weather resistance:Long-term resistance to UV radiation, moisture, and temperature fluctuations
This edge-sealing method is a core technology built on years of SuperVIG® R&D and more than 20 years of vacuum insulation expertise at its parent company, Super Tech New Material. It is also one of the industry’s most difficult technical barriers to overcome.
Difference 3: Precise Vacuum Processing
The vacuum level inside the glass directly determines its thermal and acoustic insulation performance.
A higher vacuum level improves performance, but also makes the manufacturing process exponentially more difficult.
SuperVIG® maintains an internal vacuum below 0.1 Pa—about one millionth of standard atmospheric pressure.
Maintaining this vacuum requires:
- A scientifically designed gas evacuation process
- A strictly controlled clean production environment
- Precision sealing
- Rigorous final inspection standards
What do we promise and how do we deliver?
| Precision Support Pillar System | Structural stability for over 30 years |
| Patented Edge-Sealing Materials | Long-term vacuum retention |
| High-Precision Vacuum Processing | Consistent thermal and acoustic insulation |
| Rigorous Final Inspection | Quality assurance for products |
There are more added value waited to be explored.
Overall SuperVIG® VIG is a premium VIG product that is more expensive than most insulated glass and is certainly not the cheapest option among VIG.
However, it may help with:
Save on annual heating and cooling costs (for homes in northern China, energy savings can exceed 40%)
Avoid replacement for 30 years (standard insulating glass typically lasts 10–15 years)
Improve indoor comfort and sleep quality
Divide the extra cost by 30 years, then by 365 days. What do you get for that small daily difference? You can do the math.
