Warranty & Service

At BENG glass, we think ahead. With an expected lifespan of no less than 50 years, we give you up to a 20-year warranty - that's twice as long as HR++ or HR+++ glass.

What is covered by the warranty?

• 20-year warranty on our basic range, without additional applications (layers/ hybrid etc.)
• Laminated variants: 10 years
• Fire-resistant versions: 5 years
• BENG glass Monu Restover: 5 years

Our warranty applies to the redelivery of your BENG glass window(s) free of charge if it loses its insulating effect within the warranty period. That way you can be sure you'll be fine for years to come.

We make every effort to deliver your BENG glass perfectly and carefully check each pane for insulation value before it leaves the factory. Still, sometimes something can go wrong, for example during transport or installation. No worries! We are ready to help your glazier quickly and properly.
Important: did you order your BENG glass through a glazier? Then the warranty application always goes through them. Did you order directly from us? Then you can contact us directly.

For fast and smooth warranty processing, we need the following information:

• Company name and contact person
• Order number
• Dimensions of the defective window (height x width)
• Short description of the problem
• Photos of the entire window, preferably from the inside
• Close-up pictures of the defect, also from the inside

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

Vacuum glass not only lasts longer than traditional insulating glass, it also continues to perform as if it had just been installed. With standard insulation glass, the U-value slowly decreases after a few years. With BENG glass, it remains stable - for years.

How do we know for sure? In the lab, conditions of 25 years of use are simulated. Afterwards, the U-value was still exactly the same. Therefore, we confidently guarantee a 25-year service life, with an expected total service life of 50 years.

And with a 20-year warranty, BENG glass is well above the market standard - that's 10 years more than usual in the glass world.

At BENG glass, we think ahead. With an expected lifespan of as much as 50 years, we give you up to a 20-year warranty - that's twice as long as standard insulating glass.

What is covered by the warranty?

• 5-year warranty on BENGglas Monu Restover

Our warranty applies to re-supplying your window(s) free of charge if it loses its insulating properties within the warranty period. So you can be sure you'll be fine for years to come.
