What is the warranty period of BENGglas?

At BENGglas, we think ahead. Thanks to the expected lifespan of no less than 50 years, we offer you up to 20 years warranty— that's twice as long as with HR++ or HR+++ glass.

What is covered by the warranty?

  • 20 years warranty on our basic range, without extra applications
  • 10 years warranty on our specials with extra applications.
  • 5 years warranty on fire-resistant vacuum glass

What do we mean by extra applications:

  • All products that fall under ''BENGglas specials'', including BENGglas Monu
  • Hybrid vacuum glass
  • Laminated vacuum glass

Our warranty covers the free re-delivery of your BENGglas pane(s) if they lose their insulating function within the warranty period. This way, you can be sure that you are well covered for years.

How do I claim a warranty at BENGglas?

We do everything we can to deliver your BENG glass perfectly and carefully check each pane for insulation value before it leaves the factory. However, sometimes something can go wrong, for example during transport or installation. No worries! We are ready to assist your glazier quickly and efficiently.
Important: Did you order your BENG glass through a glazier? Then the warranty request always goes through them. Did you order directly from us? Then you can contact us directly.

For a quick and smooth warranty process, we need the following information:

  • Name and contact person of the company
  • Order number
  • Dimensions of the defective pane (height x width)
  • Brief description of the problem
  • Photos of the entire pane, preferably from the inside
  • Close-up photos of the defect, also from the inside

The clearer the information, the faster we can assist you with the warranty request. Once we receive the request, we will contact you as soon as possible and arrange the next steps together.

What is the lifespan of BENGglas?

BENGglas not only lasts longer than traditional insulating glass, it also continues to perform as if it were just installed. While the U-value (insulation value) of standard insulating glass decreases after a few years, it remains stable with BENGglas – for years.

How do we know that? In the lab, the conditions of 25 years of use are simulated. Afterwards, the U-value was found to be exactly the same. That’s why we confidently guarantee a lifespan of 25 years. The expected lifespan? No less than 50 years.

And with a warranty of up to 20 years, you are well above the standard with BENGglas — that is 10 years more than what is common in the glass industry.
