What Is Vacuum Glass

 

 

Vacuum glass is a highly insulating type of glass consisting of two tempered glass panes with a thin vacuum gap. The vacuum minimizes both heat and sound transfer to the utmost minimum, effectively keeping cold and noise outside.One of the panes has a Low-E coating on the glass, reflecting heat from the interior back into the home. This prevents heat from escaping the home through the glass.

 

Advantages of Vacuum Glass

 

 

Noise reduction
The high vacuum gap of vacuum glass can effectively block the sound transmission, and the impact on the auditory experience varies by 3 to 4 times for every 5db increase in noise. Weighted sound insulation measurements show that the outdoor noise of 75db can be reduced by 41db, while the typical noise reduction effect of ordinary laminated glass is only 29db. It has a significant sound insulation effect on medium and low frequency noise such as traffic and construction.

 

Save energy
The excellent insulation value of vacuum glass provides significant savings on your energy bills. Because the glass insulates well, you need to heat less and therefore consume less energy. This not only results in lower energy bills, but is also good for the environment. Moreover, compared to the savings on your energy bill, the cost of vacuum glass is relatively low. Thus, it is a sustainable and profitable investment.

 

More comfortable living or working environment
Another advantage of vacuum glass is that it provides a more pleasant indoor environment. Because the glass insulates well, it stays warm in the winter and cool in the summer. This makes for a more comfortable living or working environment and contributes to increased productivity and well-being.

 

‍Safety
Security is an important aspect of any building, and vacuum glass also offers advantages in this area. This is because it is stronger than traditional insulating glass and has a higher resistance to break-ins and fire, for example. This is because the vacuum between the panes of glass makes the glass less likely to break and to stay together in case of breakage. This reduces the risk of injury. Moreover, vacuum glass can also be combined with additional safety film, making the glass even stronger.

 

Long service life and low maintenance
Vacuum glass has a long lifespan and is low maintenance. The glass is resistant to external influences such as uv rays and extreme temperatures. In addition, it is easy to keep clean and no special maintenance is required to maintain its insulation value.

 

Sustainability and environmental friendliness
In addition to energy savings and longevity, vacuum glass is also a sustainable and environmentally friendly solution. The glass is fully recyclable and no harmful substances are required for production. In addition, the energy saving helps reduce co2 emissions and is thus good for the environment.

Heat at 450 °c for 15 to 60 minutes to remove moisture and organic matter attached to the glass;

Seal two glass panes edge with solder glass to form a whole piece;

Open a venting hole at an appropriate position for vacuum extraction by using a vacuum pump, ensuring the vacuum pressure between the two glass panes reaching 0.001 mm HG to make vacuum glass.

 

 
How to Choose a Vacuum Glass
 
01/

U-value: The U-value measures the rate of heat transfer through the glass. The lower the number of the U-value, the better the property in thermal insulation. Look for a vacuum glass with a low U-value.

02/

Solar Heat Gain Coefficient (SHGC): A lower SHGC means less heat is transmitted through the glass. If you live in a hot climate, look for a vacuum glass with a low SHGC.

03/

Visible Transmittance (VT): The VT measures how much light passes through the glass. A higher VT means more light is transmitted through the glass. If you want more natural light in your home or office, look for a vacuum glass with a high VT.

04/

Sound Transmission Class (STC): The STC measures how well the glass blocks sound. If you live in a noisy area or near a busy street, look for a vacuum glass with a high STC.

05/

Durability: Look for tempered vacuum glass that is durable and long-lasting.

06/

Cost: Vacuum glass can be expensive, so make sure to choose one that fits your budget.

 

 

How the Vacuum Glass Works

In vacuum glass, the cavity has all the air removed. Because heat and sound cannot cross a vacuum, this makes for a very efficient window with great insulation properties.
Because a vacuum has the same properties no matter if it's .1mm or the vastness of space, the cavity between the two panes can be incredibly small and still have the same heat and sound-insulating properties.

Q: What is the difference between insulated glass and vacuum glass?

A: Insulating glass usually has its interspace filled with gas. When installed horizontally, its U-value rises due to the increase of gas convection. In comparison, vacuum insulated glass contains no air between the glass panes. U-value remains constant regardless of the position of installation.

Q: What is the R-value of vacuum insulated glass?

A: Well-insulated walls deliver R-12 to R-20 insulation, 3 to 5 times less heat loss than triple glazed windows.

Q: Is vacuum insulated good?

A: This design provides excellent insulation, keeping your beverages at the perfect temperature for an impressive 6-8 hours when hot, and over 12 hours when cold. Glass vacuum insulation is known for its incredible heat retention and its ability to retain the flavor and quality of your drinks.

Q: What is the purpose of vacuum insulation?

A: Vacuum insulation is a simple yet ingenious concept that relies on the principle of thermal conductivity. In simpler terms, it's all about minimizing heat transfer between the contents of the bottle and the external environment.

Q: How is vacuum insulation made?

A: The core material consists of a pressed powder board of fumed silica and is not flammable. It is sealed under vacuum with a gas-vapor-tight film. By creating a vacuum, gas conduction is virtually eliminated.

Q: What are the advantages of glass in construction of vacuum system?

A: Both materials are used in Ultra High Vacuum (UHV) and Ultra Clean Vacuum (UCV). Glass benefits from its low coefficient of thermal expansion (CTE), its inertness towards harsh chemical environments and low thermal and electric conductivity.

Q: Which glass is best suitable for vacuum system?

In addition, the material has high transmission in the visible range and a low coefficient of thermal expansion, making it resistant to thermal shock.

Q: What is the advantage of having a vacuum between the two glass walls?

A: The vacuum between the glass walls prevents heat loss by preventing radiation. Hint: A vacuum flask or thermos flask is designed so that it will not allow heat loss by any means of conduction or radiation. The vacuum prevents the heat loss by conduction because vacuum is a bad conductor of heat.

Q: What is glass vacuum coating?

A: Vacuum coating is a finishing process during which the metal is applied to the surface of the input product by the PVD method. Coating takes place in special vacuum systems and is not only cost-effective but above all very environmentally friendly.

Q: Is vacuum glass expensive?

A: High Price. One common criticism of vacuum glazing is its initial higher cost compared to double glazing. However, it is important to consider the long-term benefits and return on investment (ROI) that vacuum glazing offers.

Q: Why is vacuum not used in double glazing?

A: Most double glazing consists of two panes of glass separated by a cavity. Some people think that the gap in the windows is a vacuum, but that is not true. The cavity is usually filled with a noble gas, such as Argon. This gas slows down the heat that's trying to escape your room – this is called thermal transfer.

Q: Is vacuum glass worth it?

A: Vacuum double glazing is much more expensive than both standard double glazing and triple glazing although it will provide greater value thanks to its u-values and longer expected lifespan. Whilst vacuum double glazing can make a great investment for your glazing needs, the payback time could be prohibitive for most.

Q: Is double glazing a vacuum?

A: While there is no regular vacuum in double glazing, the airtight seal created by the spacer does make it an effective barrier against heat loss.

Q: Is vacuum insulated good?

A: This design provides excellent insulation, keeping your beverages at the perfect temperature for an impressive 6-8 hours when hot, and over 12 hours when cold. Glass vacuum insulation is known for its incredible heat retention and its ability to retain the flavor and quality of your drinks.
