Exceptional Options With the Vacuum Glass

Vacuum glass has a lengthy history in the glass industry despite its novelty. In the future, it is expected that vacuum glass will be one of the greatest thermal insulation glass products on the market, despite the fact that it is a relatively new product. This article will provide an overview of vacuum glass, including its advantages and future market possibilities. At first you will need to know what’s vacuum glass.

Vacuum glass, what is it?

As with ordinary insulated glass, vacuum glass is made up of two pieces of single-piece glass and a spacer.

A number of glass types and coatings are available for a range of purposes, including low-iron, silk screen, low-E, and even laminated varieties.

The vacuum gap separates the two pieces of glass, which makes a huge impact. Air spacers that are 6mm, 9mm, 12mm, 16mm, and even 20mm thick are common in traditional insulated glass.

0.2-0.4mm of vacuum is formed when two pieces of glass are fused together. To ensure that the vacuum glass does not shrink, mineral support points are put between the two pieces of glass.

Created from glass particles or metal, the sealed edge helps keep a high vacuum between the glass panes in place. In this vacuum glass guide you need to have a proper idea of the whole process.

Vacuum glass serves what purpose?

Due to the vacuum area between the two pieces of glass, vacuum glass provides the following benefits:

Heat-resistance insulation

Having a considerable quantity of vacuum space between the two side panes may minimize heat transmission. To fulfill passive house standards, it has an insulating value 6-10 times more than that of single-piece glass and a thermal conductivity 2-4 times larger than that of insulated glass.

Protection against sound waves

Unlike other types of glass, vacuum glass has a sound barrier of 39mm, which is the same thickness as triple laminated glass. Sound transmission through normal insulated glass is 33-36 decibels; sound transmission via vacuum glass may be as high as 39 dB.

There is a lot of condensation

A vacuum between the two pieces of glass causes the condensation point to be -50°C. Consequently, vacuum glass may be found in a wide range of low-temperature equipment, such as freezers and other domestic appliances, such as refrigerators.

People are protected by the usage of safety glass

Vacuum glazing is done using temperature glass, which is a kind of safety glass. The high temperature strength and impact resistance are also maintained at low temperatures thanks to the low-temperature sealing process. Fragile numbers and surface compression are in line with the tempered glass specification. Tempered vacuum glass’ high degree of safety is made possible by its wind load, impact resistance, and other properties.


Due of its small size, the vacuum space may be ignored. As a consequence, vacuum glass has the potential to significantly cut storage and logistics expenses. The thickness of vacuum glass is just a third or a quarter of that of insulated glass, and it is 10 kg per square meter lighter.In contrast, vacuum glass may be utilized to lower the thickness of aluminum profiles and window systems, resulting in considerable cost savings for clients, while keeping the same thermal insulation performance.While vacuum glass windows and thin aluminum windows are more expensive than triple-glazed glass units, the amount of energy they save is much greater.
