China Vacuum Glass manufacturers
SERENE Is a professional Vacuum Glass manufacturers and supplier in China, providing customized Vacuum Glass services and able to produce any Vacuum Glass for your project.
what is Vacuum Glass
Vacuum glass is made by sealing two pieces of flat glass on all sides and evacuating the gap between them (air pressure is lower than 0.1Pa). The gap between the two pieces of flat glass is only 0.1-0.2mm. The insulation principle is that the vacuum layer can isolate heat conduction, and there is no convective heat transfer. The heat transfer is mainly caused by radiation heat transfer.

Vacuum Glass Specifications and dimensions
The thickness of each layer of glass is between 3mm and 6mm, while the thickness of the vacuum layer is usually between 0.15mm and 0.4mm.
Thickness: The thickness of vacuum glass is usually between 4 and 19 mm.
Size: The maximum size of flat tempered glass can reach 2440mm×5480mm, and the minimum size is 250mm×100mm.
The maximum size of curved tempered glass is 2440mm×5000mm, and the minimum size is 600mm×400mm.
vacuum glass Features
Significant energy-saving effect: Vacuum glass effectively isolates heat conduction and convection heat transfer through its unique structural design, and relies on radiation heat transfer for heat exchange. The thermal conductivity K value of vacuum glass is low, usually between 0.48 w/m2·k and 0.9 w/m2·k, which significantly improves the thermal insulation performance of the building
Good sound insulation effect: The sound insulation performance of vacuum glass is better than that of traditional hollow glass and laminated glass. Its sound insulation principle is to avoid low-frequency resonance and matching effect, and reduce the introduction of external noise
Structural features: Vacuum glass is composed of two flat glass sheets, which are sealed on all sides and separated by supports to form a high vacuum cavity. A high vacuum state is formed inside the glass, and the external atmospheric pressure will cause the glass to slightly concave, requiring special tiny supports to keep the glass flat
Material properties: The heat transfer of vacuum glass is mainly through radiation heat transfer, and the distance between the two glass sheets is very small (only 0.1-0.2mm), so the insulation effect is very good. The sound insulation performance of vacuum glass is not affected by the thickness of the glass, and it can be compounded with other types of glass to further improve its performance.
Advantages of Vacuum Glass
Low-carbon and energy-saving:
Vacuum glass relies on the special structure of the vacuum layer to effectively block the heat conduction between indoor and outdoor, significantly reduce the power consumption of air conditioning and the emission of pollutants and greenhouse gases, and reduce environmental pollution.
Super heat insulation:
- In summer, vacuum glass can effectively control solar radiation and keep the room cool;
- In winter, even if the outdoor temperature is very low, the inner surface temperature of vacuum glass is only 3-5°C lower than the indoor air temperature, keeping the room warm and comfortable.
Super sound insulation:
Vacuum glass uses its special structure to block the propagation of sound and effectively block noise, especially for medium and low frequency sounds with strong penetration.
Anti-frost:
There are no air and water vapor molecules in the vacuum layer of vacuum glass, and the thermal resistance is very large. No condensation will occur in the glass in winter.
Long life:
Vacuum glass has a 30-year warranty, which basically guarantees the same life as the door and window system. The surface is not easy to cool, which prevents the formation of frost and water mist, and increases the durability and service life of the window frame.
Light and thin structure:
The thickness of vacuum glass is only 8~10mm, which is much thinner than insulating glass, saving installation space and window frame materials.
Suitable for plateau areas:
The internal air pressure of vacuum glass is close to zero. When used in plateau areas, it will not only not cause cracking, but also reduce the atmospheric pressure and stress of vacuum glass due to the small pressure difference, thus improving safety
Vacuum Glass producing process
Vacuum glass is composed of two sheets of flat glass separated by a support in the middle and sealed with low-melting-point glass solder or metal solder around the periphery to form a vacuum cavity. This makes vacuum glass excellent in thermal insulation. Usually, at least one low-emissivity coated glass is used in the two glass substrates to reduce heat transfer.
Vacuum Glass applications
Buildings: Vacuum glass is widely used in high-end residences, hotels, hospitals and other places that require high efficiency and energy saving due to its excellent heat insulation and thermal insulation performance. Vacuum glass can effectively reduce energy consumption and improve the comfort of living and working.
Vehicle and ship doors and windows: Vacuum glass is also commonly used in doors and windows of vehicles and ships, providing transparent insulation materials to ensure the use effect in various means of transportation.
Insulated cabinets: In areas such as display cabinets and refrigerators that require transparent insulation materials, the application of vacuum glass can improve their insulation effect.
Places with high sound insulation requirements: Vacuum glass is suitable for places with high sound insulation requirements such as residences, hotels, and recording studios near the road. Significantly reduce the impact of external noise on the indoor environment and improve the comfort of living and working.

FAQ
The difference between vacuum glass and insulating glass
Compared with insulating glass, vacuum glass has better thermal insulation and heat preservation performance. The hollow glass is filled with dry air or other gases, while the gas in the cavity of vacuum glass is very thin, almost close to vacuum, and the heat transfer coefficient is low (0.8~1.5W/㎡·K), which is much lower than the heat transfer coefficient of insulating glass (2.2~3.0W/㎡·K).
The sound insulation performance of vacuum glass is also better than that of insulating glass, which can effectively block external noise.
is it ok to vacuum glass
It is generally not recommended to vacuum glass, especially larger or sharp pieces, as they can damage the vacuum cleaner’s internal components, such as the hose or bag. Small, dull fragments might be manageable, but caution is advised.
can you vacuum glass
Yes, you can vacuum glass, but it depends on the size and type. Small, smooth pieces may be safe, but sharp or large shards can harm the vacuum. Using a vacuum with a strong filter and sturdy hose is preferable.
is it safe to vacuum glass
Vacuuming glass can be unsafe if the pieces are sharp or large, as they may puncture the vacuum bag or hose. Always wear gloves and consider using a broom and dustpan for larger shards to avoid risks.
can you vacuum glass off carpet
Vacuuming glass off carpet is possible but risky. Small pieces might get trapped in the fibers, and sharp shards could damage the vacuum. Use sticky tape or a lint roller first to pick up smaller fragments
can you vacuum up small pieces of glass
Small pieces of glass can be vacuumed, but ensure they are not sharp enough to damage the vacuum. Use a vacuum with a strong filter and empty it carefully afterward to avoid injury from the collected glass.
