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.
Why is BENGglas a smart investment?
Because you don't just buy glass, but a future-proof solution that really saves money and energy. BENGglas has an insulation value starting from 0.35 W/m²K — that's 2x better than triple glazing (0.70) and even 3x better than double glazing (1.1). Less heat loss immediately means lower heating costs. This also means a better energy label and therefore a higher property value. The effective payback period is often 0 years.
But that's not all. BENGglas lasts up to 50 years, while standard glass typically needs to be replaced after 25 years. Invest once, and you're set for two generations. That means less maintenance, less replacement, and thus lower total costs.
The environment also benefits: if the whole of the Netherlands switches to BENGglas, we save no less than 4.1 megatons of CO₂ annually — comparable to 170,000 car trips from Amsterdam to Paris. Less CO₂ emissions and a lower energy bill: that's what we call an investment that pays for itself.
In short: with BENGglas you invest in sustainability, comfort, and financial savings. Smart, right?
