Frequently asked questions
Why should I choose BENGglas?
BENGglas is not ordinary glass – it is a revolutionary solution for sustainable and future-proof building. Compared to standard insulation glass, BENGglas offers unique advantages that directly improve both your home and the climate.
- Superior insulation: with a U-value starting from 0.35 W/m²K, BENGglas is twice as effective as triple glazing (0.70) and even three times better than double glazing (1.10). This means significant energy savings and lower heating costs.
- Long lifespan: while traditional glass lasts an average of 25 years, BENGglas lasts up to 50 years. Produce once, less CO₂, and half a century of benefits!
- Sustainable and environmentally friendly: thanks to less material use (30% less glass than triple glazing), BENGglas saves thousands of tons of CO₂ annually. This way, you actively contribute to a cleaner planet.
- Light and thin: at only 8.3 mm thick, BENGglas fits in almost any existing frame and allows for lighter hardware, making construction sustainable and efficient.
- A true climate hero: if all of the Netherlands switches to BENGglas, we can save up to 4.1 megatons of CO₂ annually — that's equivalent to 170,000 car trips from Amsterdam to Paris! Moreover, the production of BENGglas alone results in 24,000 tons less CO₂ emissions per year.
- A smart investment in the future: less energy consumption, less maintenance, and a longer lifespan make BENGglas a choice that benefits you for years – for yourself and for future generations.
In short: with BENGglas you choose maximum energy efficiency, sustainability, and a smart investment in the future. Make a difference, for your home and for our planet.
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.
