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.
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.
