Frequently asked questions
What are the benefits of vacuum glass?
Vacuum glass is no ordinary insulating glass - it is a smart and future-proof solution for sustainable construction. Compared to standard insulation glass, BENG glass offers benefits that directly improve your home as well as help the climate.
- Superior insulation
With a U-value starting at 0.35 W/m²K, BENG glass is two times better than triple glazing (0.70) and three times better than HR++ glass (1.10). This ensures less heat loss, lower heating costs and a comfortable home. - No loss of insulation in slope
Many insulation glasses lose up to 60% of their performance when installed at an angle. BENG glass continues to perform. - Up to twice the lifespan
Whereas traditional glass lasts an average of 25 years, BENG glass lasts up to 50 years. Producing it once means less CO₂ and half a century of benefit. - Strong noise reduction
From 36 dB to 42 dB, well above HR++ (31 dB) and triple glazing (33 dB). As a result, you live more quietly and peacefully. Ideal for homes or properties on busy roads. - More comfort all year round
Cool in summer, warm in winter - without draughts or cold spots. - No condensation on the inside
The unique edge seal completely prevents interior condensation. - Fits into existing window frames
With only 8.3 mm thickness, BENG glass almost always fits into existing window frames. This makes renovations easier and avoids unnecessary use of materials. - A true climate hero
If the entire Netherlands switches to BENG glass, we save up to 4.1 megatons of CO₂ annually - comparable to 170,000 car trips from Amsterdam to Paris.
The production of BENG glass itself will also save 24,000 tons of CO₂ per year, thanks to production using green energy, 30% less material usage than with triple glazing, up to twice the lifespan and high insulation. - A smart investment in the future
A U-value that insulates up to 2x better and that for as much as 50 years. Combine that with an improved energy label and a higher home value and you have your costs back immediately!
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.
