With the Monostripe variant, you not only save significantly on your energy costs thanks to the strong insulation value of U=0.50, but you also generate your own energy – up to 70 watts per square meter!
The cut crystalline cells provide a sleek, even, and semi-transparent surface with a light transmission of 50%.
With a slim build starting from 14 mm, BENGglas Sun Monostripe is perfect for atriums or as a stylish element in any building.

Classic
With the Classic variant, you hit two birds with one stone: you enjoy top insulation with a U-value of 0.50 and simultaneously generate energy. With full cell coverage, this can go up to 140 watts per square meter.
The classic monocrystalline cells create a semi-transparent panel, where the light incidence can be precisely adjusted to your project.
With a slim thickness starting from 14 mm, BENGglas SUN Classic is ideal for facades, canopies, and other applications where high efficiency and a sleek appearance are required.

Frequently asked questions
The enormous CO₂ benefit of a massive switch to BENGglas: this is what it really delivers!
If the whole of the Netherlands switches to BENGglas, we achieve a structural CO₂ saving of no less than 4.1 megatons per year — that is equivalent to 170,000 car trips from Amsterdam to Paris! In production alone, BENGglas saves more than 24,000 tons of CO₂ annually. For an average house, BENGglas means a saving of 1,800 kg CO₂ per year, which can amount to as much as 90,000 kg CO₂ per house over 50 years. This directly contributes to achieving our climate goals: it can realize more than 8% of the CO₂ reduction in the built environment by 2030 and helps the Netherlands become climate neutral by 2050. It is not just glass, it is a revolution in sustainable building.
What does BENGglas cost?
The price of vacuum glass is slightly higher than traditional insulating glass, but that doesn't tell the whole story. Because with BENGglas, you also save on:
- new frames (which are often needed with HR+++)
- additional hardware
- your energy bill
- and your energy label - which results in a higher property value. Thus, the effective payback period is often 0 years.
Additionally, there are attractive subsidies on vacuum glass, which in the Netherlands can go up to €46 per m².
Our consumer advice price?
As a guideline, you can count on a price starting from €285 per m² (excluding VAT, transport, and installation).
The final costs depend on your specific situation: type of frame, glass choice (e.g., laminated or sun-protective), and any additional wishes such as painting or finishing.

Is there no dealer near you? Then ask your local glazier to contact BENGglas via info@bengproducts.nl.
What glass thickness do I need?
BENGglas is available in various thicknesses, so we always have the perfect match for your windows. This prevents distortion, warping, and other issues.
The larger the glass, the thicker the build. The glass thickness is determined based on the surface area of a single pane:
- 8.3 mm: up to 3 m²
- 10.3 mm: from 3 to 4 m²
- 12.3 mm: from 4 to 4.8 m²
- 16.3 mm: from 4.8 m²
Is BENGglas too thin for your frames? No problem!
BENGglas is ultra-thin, but if your frames are wider than 16.3 mm, we can also thicken (BENGglas Hybrid) or laminate the glass. This way, it fits perfectly into wider profiles without needing to replace your frames.
Not sure which thickness is best for your windows? No stress, we are happy to help you with personalized advice that fully matches your situation!
Is BENGglas soundproof glass?
BENGglas is not only very strong in insulation but also effective in blocking sound. We measure this with the RW (C; Ctr) values — the higher the number, the quieter your home becomes.
Here are the figures at a glance:
- Double glazing has a general sound insulation of about 31 dB, with a range of 30 to 27 dB at low and high frequencies.
- Triple glazing scores slightly better with a general value of 33 dB, but at low and high frequencies, the sound level can vary from 31 to 27 dB.
- BENGglas goes a step further with a general sound insulation of 36 dB and performs very consistently at low and high tones between 34 and 33 dB.
What does that mean for you? BENGglas keeps sound out better, especially those annoying low tones that you quickly suffer from.
This way, you not only enjoy a lower energy bill but also a much quieter and more comfortable home.
