No insulation glass but a revolution
We face the greatest challenge of our time: the climate crisis. Yet the biggest energy leak in our buildings often remains invisible: glass. One of the largest and least addressed components of the building envelope.
BENGglas breaks that pattern and offers the most impactful – and most underexposed – solution for the energy transition: vacuum glass.
- With an unprecedented low U-value starting from 0.35 W/m²K
- Saves twice as much energy as triple glass (U = 0.70)
- Three times as much as HR++ glass (U = 1.10)
- Lasts up to 50 years – twice as long as standard insulating glass
- So thin that it fits in any frame and saves material
- Produced with 30% less material than triple glass
An innovation that not only saves energy but also drastically reduces raw materials, transport, and CO₂ emissions.

The impact of massive application
If we collectively switch to BENG glass, we achieve together:
- Up to 50% less CO₂ emissions in households
- Structurally lower CO₂ emissions during production
- 50% less required raw materials and transport
- Less building material, thanks to the preservation of existing frames and lighter hardware
- Only one production cycle every 50 years
- A 30% saving on required glass volume
- A structural saving for generations after us

The hidden saving
In the Netherlands alone, approximately 8 million m² of HR++ and triple glass is produced annually. If we completely replace this with BENGglas:
- We will structurally save over 24,000 tons of CO₂ per year
- That is equivalent to 170,000 car trips from Amsterdam to Paris
And that is just the saving on production. The real gain lies in the usage.

A direct contribution to our climate goals
The Netherlands aims for a 55% reduction in emissions by 2030, and full climate neutrality by 2050. Simply by replacing outdated glass with BENG glass:
- We achieve more than 8% of the built environment target for 2030
- We make a lasting contribution to a climate-neutral Netherlands by 2050

About us
At BENGglas, we really make a difference, not only in insulation but for our future. Our vacuum glass offers an unprecedented low U-value of 0.35, up to 50 years of lifespan, and -36 dB noise reduction — all in your existing frames, without heavy metals and with up to 30% less material usage than triple glazing.
