Vacuum glazing

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.

This glass is a technological marvel that even surpasses the thermal insulation of triple glazing. And all of this with a glass thickness of only 8 or 10 mm, making it suitable for almost any window frame, including those in old and historic buildings.

Key features and benefits of vacuum glass:

• Thermal insulation: Vacuum glass provides excellent thermal insulation due to the absence of air molecules between the glass panes. This helps reduce heat transfer, making it an effective solution for energy-efficient buildings.
• Reduced heat loss: The vacuum minimizes conduction, convection, and radiation between the panels, resulting in less heat loss compared to traditional double or triple glazing.
• Sleek design: Vacuum glass can be designed with a thinner profile than traditional double-glazed windows while maintaining similar or superior insulation properties. This sleek design offers more flexibility in architectural applications.
• Improved sound insulation: The vacuum between the glass panes also helps reduce sound transmission, making vacuum glass a potential solution for sound control in urban environments.
• Condensation prevention: The absence of air between the panels minimizes the chance of condensation on the inner surfaces of the glass, improving visibility and preventing potential damage.
• Enhanced energy efficiency: By reducing the need for heating and cooling, vacuum glass contributes to overall energy efficiency in buildings, aiding in achieving sustainability goals and lowering energy costs.

What is the cost of vacuum glass?

While vacuum glass offers several significant benefits, it is essential to note that it is a relatively advanced and costly technology. The production process and the need for a hermetically sealed edge to maintain the vacuum contribute to higher production costs. However, as the technology advances and becomes more widely applied, costs are expected to decrease, making vacuum glass an increasingly accessible option for various applications.
Compared to regular double and triple glazing, it is a relatively expensive type of glass. However, the possibilities and insulation values are significantly better. The additional cost can be easily recouped in the long term.

Where do you use vacuum glass?

You use vacuum glass primarily in situations where high thermal and/or sound insulation is needed, but the frame does not allow for thick insulation glass. Vacuum glass can be effectively used in old buildings, including monuments. This way, you preserve the frames and the appearance while maximizing insulation with this type of glass.
