What is vacuum glass?
Vacuum glass consists of two glass panes with a vacuum layer of less than a millimetre between them. That vacuum insulates exceptionally well: in just 6.7 mm you achieve a U-value down to 0.35 W/m²K — comparable to or better than triple glazing, but much thinner and lighter.
This makes it ideal for monuments and slim, existing frames where thick insulating glass doesn't fit. You keep the authentic appearance and get modern insulation.

Frequently asked questions about vacuum glass
What exactly is vacuum glass and how does it work?▾
Vacuum glass is the latest generation of insulating glass. Instead of a cavity with gas (as in HR++), there is a completely vacuum space between the two wafer-thin glass plates: a vacuum. Because there is no air or gas to conduct heat, the insulation value is extremely high. The result is a pane as thin as single glass that insulates better than the thickest triple walls.
Why are there small dots in the vacuum glass?▾
Up close you can see a tight pattern of tiny dots: the micro-spacers or spacers. Because the space between the glass plates is vacuum, an enormous atmospheric pressure is created that pulls the plates together. These dots ensure that the plates do not touch each other and the window does not implode. From a short distance they are hardly noticeable. Curious what that looks like? View our knowledge base article on BENG glass with examples and photos.
What is the advantage of vacuum glass over triple glass?▾
The biggest advantage is the thickness and weight. Triple glazing is easily 40 to 50 mm thick and very heavy, so it often does not fit into existing window frames. Our vacuum glass is on average only 8 to 12 mm thick and therefore almost always fits directly into your current wooden, plastic or aluminum frames — and even in monumental buildings. You save on your energy bill without replacing all your window frames.
Is vacuum glass suitable for monuments or historic buildings?▾
Yes, excellent. Precisely because vacuum glass is so thin, it is the solution for monumental buildings. Often the appearance should not change and the slim frames are not suitable for thick, heavy HR++ or triple glazing. With vacuum glass you retain the authentic, sleek appearance and enjoy modern comfort and insulation. Because renovation of monuments is tailor-made and complies with strict rules, we are happy to help you from the start - please feel free to contact us.
Can I order vacuum glass in any size?▾
Because vacuum glass is vacuumed under high pressure and the micro-spacers must be positioned exactly, production requirements apply to the dimensions. The maximum plate size for our BENG glass is 2350 × 4150 mm. In the configurator you can immediately see whether your measurements fall within the margins. Please note: vacuum glass cannot be sawn or processed after production, so accurate measuring is crucial. View our measuring instructions in the knowledge base.
