Saving more energy and CO₂ without demolition with BENG glass

With a U-value of only 0.40, BENG glass far exceeds both HR++ (approximately 1.1) and HR+++ glass (approximately 0.7). This means that you insulate up to 3 times better than with HR++ and almost 2 times better than with HR+++. Less heat loss means lower heating costs and a substantial reduction in your CO₂ emissions - on average, you save up to 750 kg of CO₂ per year per home. That's good news for the environment and your wallet.

But the biggest advantage?
BENG glass is so thin (8.3 mm) and light that it fits into existing window frames without any modifications. No demolition, no dust, no expensive renovations. This not only keeps the authentic look of your building intact, but also saves you money and time.

In short: choosing BENG glass means choosing the best insulation, maximum energy savings, lower CO₂ emissions and hassle-free renovation. This makes BENG glass the smart, sustainable and future-proof solution for any renovation project.

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.
