Frequently asked questions
The huge CO₂ gain from mass switching to BENG glass: this is what it really delivers!
If all of the Netherlands switches to BENG glass, we realize structural CO₂ savings of as much as 4.1 megatons per year - that's equivalent to 170,000 car trips from Amsterdam to Paris! In production alone, BENG glass saves over 24,000 tons of CO₂ annually . For an average home, BENG glass means a saving of 1,800 kg of CO₂ per year, which over 50 years can increase to as much as 90,000 kg of CO₂ per home. BENG glass thus contributes directly to achieving our climate goals: it can achieve more than 8% of the CO₂ reduction in the built environment by 2030 and help the Netherlands become climate neutral by 2050. It's not just any glass, it's a revolution in sustainable building.
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.

What glass thickness do I need for my vacuum glass project?
BENG glass comes in different thicknesses, so we always have the perfect match for your windows. This prevents distortion, warping and other hassles .
The larger the glass, the thicker the construction. Glass thickness is determined based on the surface area of a single pane of glass:
- 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 BENG glass too thin for your window frames? No problem!
BENG glass is ultra-thin, but if your frames are a bit wider than 16.3 mm, we can also thicken (BENG glass Hybrid) or laminate the glass. This way it even fits perfectly into wider profiles, without having to replace your frames.
Not sure what thickness best suits your windows? No stress, we are happy to help you with a personal advice that fits your situation perfectly!
Is BENG glass soundproof?
BENG glass 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. In general, the better the insulation value, the better the soundproofing. So by using the best insulation value, BENG glass also directly provides the best sound insulation!
Here are the figures at a glance:
- HR++ glass has an overall sound insulation of about 31 dB, with a range of 30 to 27 dB at low and high frequencies.
- HR++ glass or triple glass scores slightly better with an overall value of 33 dB, but at low and high frequencies the sound level can range from 31 to 27 dB.
- BENG glass goes one step further with an overall sound insulation of 36 dB and also performs very consistently between 34 and 33 dB at low and high frequencies.
What does that mean for you? BENG glass keeps sound out better, especially at those annoying low tones that easily bother you.
So you not only enjoy lower energy bills, but also a much quieter and more comfortable home.
