Features of vacuum glazing

Thin Profile

One of the notable aspects of vacuum glazing is its thinness. The overall thickness can be less than 7 mm compared to traditional double glazing, which usually ranges from about 24 mm to 28 mm.

Low U-Value

The U-value of vacuum glazing can be significantly lower than traditional glazing, indicating better insulating properties. It can achieve U-values around 0.7 W/m²K or lower, depending on the design. Single glazing will have a U-value 5.8 W/m²K and so vacuum glazing is a considerable improvement. In fact, vacuum glazing achieves the same efficiency as triple glazing and yet it is roughly the same thickness as that of a single pane of glass.

High Visibility

The clear glass allows for high transparency, ensuring ample natural light while minimizing heat loss.

Durable Sealing

The vacuum seal is typically achieved through specialized manufacturing techniques, making these units durable and resistant to moisture and air infiltration.

Applications of Vacuum Glass

Heritage Window Restoration Projects: Perfect for listed buildings where single glazing is required. At only 8.3mm thick, vacuum glass provides modern energy efficiency without compromising the building's historical character. This makes it an excellent option for conservation areas where traditional glazing must be retained.

New Builds and Modern Homes: Its sleek profile and high performance make it a natural choice for contemporary designs.

Residential Homes: Ideal for renovations or new constructions aiming for better insulation and sustainability.

Commercial Buildings: Offices, retail spaces, and public buildings can benefit from the energy savings and soundproofing of vacuum glass.

The production process of glass

Raw material preprocessing. The block raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed, so that the wet raw materials dry, iron containing raw materials for iron removal treatment, in order to ensure the quality of glass.

Preparation of mating materials.

The melting system. The glass mixture is heated at a high temperature (1550~1600 degrees) in the pool kiln or crucible kiln to form a liquid glass that is uniform, bubble-free and in line with the requirements of forming.

To shape. Process liquid glass into the desired shape of the product, such as plate, various utensils, etc.

Heat treatment. Through annealing, quenching and other processes, the stress, phase separation or crystallization inside the glass can be eliminated or generated, and the structural state of the glass can be changed.

FAQ

Q: Is vacuum glazing more expensive than traditional glazing options?

A: Due to advanced processing and materials, vacuum glazing is usually expensive upfront. However, it can be cost-effective in the long run by offering this much energy efficiency that there will be less cost expended on heating and cooling.

Q: What kind of maintenance is required for vacuum glazing windows?

A: There is very little maintenance required for vacuum glazing other than cleaning, as its hermetically sealed unit avoids condensation and water/dampness from building up.

Q: How long do vacuum glazing windows typically last?

A: If well-maintained, the vacuum glazing window is going to last upwards of 25-30 years or even more due to its robust build and sealed design.

Q: What are the latest innovations in vacuum glazing technology?

A: Recent innovations include improvements to thermal and acoustic insulation, increasing manufacturing efficiency, and finding new materials to maximise performance even further.
