Duco ventilation grilles

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!

Good news! Thanks to the Sustainable Energy and Energy Saving Investment Subsidy (ISDE), you get a nice compensation if you preserve your home with BENG glass:

• € 111 per m² if you also replace your window frames (report code: other)
• € 46 per m² if you live in a national monument and replace the glass with BENG glass

And it gets even better: if you also take other insulation measures, such as roof or floor insulation, the amount is doubled!

Are you an entrepreneur and do you want to make your business premises more sustainable?

BENG glass comes in different thicknesses, so we always have the perfect match for your windows. This prevents distortion, warping and other hassles .
The larger the glass, the thicker the construction. Glass thickness is determined based on the surface area of a single pane of glass:

• 8.3 mm: up to 3 m²
• 10.3 mm: from 3 to 4 m²
• 12.3 mm: from 4 to 4.8 m²
• 16.3 mm: from 4.8 m²

Is BENG glass too thin for your window frames? No problem!
BENG glass is ultra-thin, but if your frames are a bit wider than 16.3 mm, we can also thicken (BENG glass Hybrid) or laminate the glass. This way it even fits perfectly into wider profiles, without having to replace your frames.

Not sure what thickness best suits your windows? No stress, we are happy to help you with a personal advice that fits your situation perfectly!

The smallest standard size of BENG glass is 200 × 230 mm. Smaller is sometimes possible, as long as the diagonal is at least 300 mm.
The largest size? 2,350 × 4,150 mm - unique in the world of vacuum glass and another good example of why BENG glass stands out.
