What is vacuum glass ?

Vit is an official partner of AV ELIA, tempered vacuum glazing.

Vacuum glazing represents a major technological advance in the field of glazing. This type of glazing, consisting of two glass panes separated by an extremely narrow space, uses an innovative technique that creates a vacuum between the panes. This technology offers exceptional thermal and acoustic performance while remaining extremely light and thin. Vacuum glazing is ideal for applications where insulation is paramount, while maintaining a modern and refined aesthetic.

Vacuum glazing is used in numerous applications, ranging from high-performance windows to curtain walls and other glass façades, particularly in the construction, renovation and architecture sectors. This revolutionary glazing meets the most stringent energy efficiency standards while offering undeniable aesthetic advantages.

What are the advantages of vacuum glazing ?

Vacuum glass offers numerous advantages that make it an essential solution
in many fields, particularly construction and architecture.
Exceptional thermal insulation
The main advantage of vacuum glazing is its ability to provide superior thermal insulation. Thanks to the vacuum between the glass panes, it reduces heat loss and significantly improves the energy efficiency of buildings.

Ug=0,4 W/m²K

Enhanced sound insulation
In addition to its thermal properties, vacuum glazing also offers remarkable sound insulation. It helps to limit the transmission of external noise, making it ideal for urban areas or noisy environments.
Space saving
Vacuum glazing is much thinner than traditional double or triple glazing while offering similar performance, saving space while maintaining optimal energy efficiency.
Lightweight and robust
Despite its thinness, vacuum glazing is extremely strong thanks to its tempered glass surfaces. It offers strength comparable to that of traditional tempered glass.
Warranty
AV ELIA vacuum glazing is guaranteed for 15 years and approved by the CSTB.

Technical characteristics of vacuum glass ?

Vacuum glazing consists of two panes of glass separated by a very thin space, creating a near-total vacuum. This process maximises thermal and acoustic insulation while reducing the thickness of the glazing.
Structure :

The glazing consists of two sheets of ultra-resistant glass, with an air or gas gap, sealed together.

Thermal performance :

A very low thermal transmittance coefficient (U-value), which helps retain heat in winter and insulate against heat in summer.

Performances acoustiques :

Une réduction significative du bruit, rendant ce vitrage idéal pour les bâtiments situés dans des environnements bruyants.

Dimensions and thickness :

Vacuum glazing is thinner than conventional glazing solutions while maintaining the same performance, with a thickness that can vary depending on the project requirements.

Sustainability :

Thanks to its vacuum sealing technology, this glazing is highly durable and resistant to temperature variations and humidity.

FAQ – Your frequently asked questions about vacuum glass

What is vacuum glazing ?

Vacuum glazing is a type of glazing composed of two glass panes separated by a space from which all air or gas has been removed. This provides exceptional thermal and acoustic insulation while reducing the thickness of the glazing.

What are the advantages of vacuum glazing ?

Vacuum glazing offers remarkable thermal and acoustic insulation, is lighter and thinner than conventional glazing, and provides better performance.
It is also more resistant and durable.

Where can vacuum glazing be used ?

Vacuum glazing is ideal for applications where thermal and acoustic insulation are essential, such as windows, façades, curtain walls, or in buildings located in noisy environments or those exposed to significant temperature variations.

Is vacuum glazing more expensive than traditional glazing ?

Although vacuum glazing may have a higher initial cost due to the manufacturing technology, its insulation performance delivers long-term energy savings, making it a cost-effective investment in the long run.

Is vacuum glazing suitable for renovation projects ?

Yes, vacuum glazing is perfectly suited to renovation projects, particularly for improving the thermal and acoustic insulation of existing buildings while maintaining a modern and elegant design. What’s more, its slim profile allows it to be integrated into older window frames that are not compatible with traditional insulating glazing.
