Frequently asked questions
What are the benefits of vacuum glass?
Vacuum glass is no ordinary insulating glass - it is a smart and future-proof solution for sustainable construction. Compared to standard insulation glass, BENG glass offers benefits that directly improve your home as well as help the climate.
- Superior insulation
With a U-value starting at 0.35 W/m²K, BENG glass is two times better than triple glazing (0.70) and three times better than HR++ glass (1.10). This ensures less heat loss, lower heating costs and a comfortable home. - No loss of insulation in slope
Many insulation glasses lose up to 60% of their performance when installed at an angle. BENG glass continues to perform. - Up to twice the lifespan
Whereas traditional glass lasts an average of 25 years, BENG glass lasts up to 50 years. Producing it once means less CO₂ and half a century of benefit. - Strong noise reduction
From 36 dB to 42 dB, well above HR++ (31 dB) and triple glazing (33 dB). As a result, you live more quietly and peacefully. Ideal for homes or properties on busy roads. - More comfort all year round
Cool in summer, warm in winter - without draughts or cold spots. - No condensation on the inside
The unique edge seal completely prevents interior condensation. - Fits into existing window frames
With only 8.3 mm thickness, BENG glass almost always fits into existing window frames. This makes renovations easier and avoids unnecessary use of materials. - A true climate hero
If the entire Netherlands switches to BENG glass, we save up to 4.1 megatons of CO₂ annually - comparable to 170,000 car trips from Amsterdam to Paris.
The production of BENG glass itself will also save 24,000 tons of CO₂ per year, thanks to production using green energy, 30% less material usage than with triple glazing, up to twice the lifespan and high insulation. - A smart investment in the future
A U-value that insulates up to 2x better and that for as much as 50 years. Combine that with an improved energy label and a higher home value and you have your costs back immediately!
What does BENG glass cost?
The price of vacuum glass is slightly higher than traditional insulation glass, but that doesn't say it all. Because with BENG glass you also save on:
- new window frames (which are often needed with HR++)
- replacement costs due to twice the lifespan
- extra hinges and locks
- your energy bill with a stable U-value for up to 50 years
- and your energy label - resulting in a higher home value. Thus, the effective payback period is often 0 years.
In addition, there are attractive subsidies on vacuum glass, which in the Netherlands can be as much as €46 per m².
Our consumer advice price?
As a guideline, you can count on a price starting from €285 per m²(excl. VAT, transport and installation, based on 1 m²).
The final cost depends on your specific situation: type of frame, choice of glass (e.g. laminated or solar control) and any additional requirements such as painting or finishing. It is therefore difficult to give an exact price. Would you like a quote including installation? Then fill in our quotation form and receive 3 quotations from 3 authorized dealers in your area.
