No insulation glass but a revolution

We face the greatest challenge of our time: the climate crisis. Yet the biggest energy leak in our buildings often remains invisible: glass. One of the largest and least addressed components of the building envelope.

BENGglas breaks that pattern and offers the most impactful – and most underexposed – solution for the energy transition: vacuum glass.

  • With an unprecedented low U-value starting from 0.35 W/m²K
  • Saves twice as much energy as triple glass (U = 0.70)
  • Three times as much as HR++ glass (U = 1.10)
  • Lasts up to 50 years – twice as long as standard insulating glass
  • So thin that it fits in any frame and saves material
  • Produced with 30% less material than triple glass

An innovation that not only saves energy but also drastically reduces raw materials, transport, and CO₂ emissions.

The impact of massive application

If we collectively switch to BENG glass, we achieve together:

  • Up to 50% less CO₂ emissions in households
  • Structurally lower CO₂ emissions during production
  • 50% less required raw materials and transport
  • Less building material, thanks to the preservation of existing frames and lighter hardware
  • Only one production cycle every 50 years
  • A 30% saving on required glass volume
  • A structural saving for generations after us

The hidden saving

In the Netherlands alone, approximately 8 million m² of HR++ and triple glass is produced annually. If we completely replace this with BENGglas:

  • We will structurally save over 24,000 tons of CO₂ per year
  • That is equivalent to 170,000 car trips from Amsterdam to Paris

And that is just the saving on production. The real gain lies in the usage.

A direct contribution to our climate goals

The Netherlands aims for a 55% reduction in emissions by 2030, and full climate neutrality by 2050. Simply by replacing outdated glass with BENG glass:

  • We achieve more than 8% of the built environment target for 2030
  • We make a lasting contribution to a climate-neutral Netherlands by 2050
