The power of Bengglas®
Bengglas® delivers unparalleled insulation performance (up to U = 0.35) and thus surpasses ample triple glass (U = 0.80), double glazing HR ++ (U = 1.10) and other brands vacuum glass (U = 0.70).
Thanks to the ultra -thin thickness of only 8.3 mm, Bengglas® fits effortlessly into existing frames. This not only saves on extra material costs, but also makes it possible to make protected monuments more sustainable - without radical adjustments to the frames.

- TO ORDER
Bengglas® has an expected lifespan of 50 years. The tested lifespan (through a lab test) lies at least 25 years while retaining the insulation value.
Compared to double glazing HR++ (20-25 years) or triple glazing HR+++ (30 years), where the U-value slowly decreases over the years, vacuum glass offers many advantages.
Conditions over a period of 25 years can be simulated using a lab test. After such a test, the U-value (insulation value) appeared to have been fully maintained; the tested lifespan is therefore 25 years. The expected lifespan of vacuum glass is 50 years.
Bengglas® stands for long -term reliability, with a solid guarantee of 15 years. This is considerably longer compared to traditional insulating glass, the warranty of which is often limited to only 10 years.
The warranty only covers the redelivery of the high-quality vacuum glass.
Yes, it is absolutely possible to make Bengglas® burglar -resistant. This is possible with a tempered outfit. The minimum glass thickness thus becomes 13.06 mm, 16.06 mm or 19.06 mm depending on the window surface.
If laminated with a tempered eraser, you make Bengglas® not only extra burglar -resistant, but also extra sound -damping (from -36 dB to -39 dB) and fall -safe.
Depending on the degree of protection, a different glass construction can be put together as desired.
The insulation value remains the same even after laying.
The entire range of Bengglas® is completely tempered.
This is what also makes BENGglas® unique, because the glass is already injury-proof as standard and 5x stronger without the risk of thermal breakage, without any additional costs.
Absolutely, but only in a layered version as this is legally required. Making the glass fall-proof through layers entails a small additional cost per square meter. However, you immediately enjoy numerous additional benefits, including:
- No degradation of the insulation value in slope angle
- Savings on the roof construction due to the lightweight design
- Additional noise reduction: from -36 dB to -39 dB
- Since the glass is tempered as standard, no thermal breakage can occur
Unlike other insulating glass, BENGglas® does not lose its insulation value at an angle of inclination. This makes BENGglas® extremely suitable for roof glazing.
Bengglas® is available as standard in the glass thicknesses 8.3 - 10.3 or 12.3 mm. Depending on the total window surface, a minimum glass thickness is advised:
- 8.3 mm: <2 m²
- 10.3 mm: 2 - 3 m²
- 12.3 mm: 3 - 4.5 m²
- 16.3 mm:> 4.5 m²
In addition, it is possible to thicken or lay down Bengglas®.
If you low the window with a tempered eraser, Bengglas® immediately becomes extra burglar -resistant, sound -resistant and fall -safe. This makes the minimum glass thickness 13.06 - 16.06 or 19.06 mm. If desired, on request (due to the application of additional burglar -resistant or fire -resistant films), you can be lost.
If you want to top the window (for example, to mount it in an existing double or triple glass of frame, an extra cavity including the standard 8.3 mm, 10.3 mm or 12.3 mm glass package can be placed. The cavity options amounts 6, 9, 15, 16, 18 or 20 millimeter thick with a break of 4, 6,).
The U-value (insulation value) of the vacuum insulating glass remains the same even after 'thickening' or 'layering'.
Yes, it is absolutely possible to lay Bengglas®. This is possible with a tempered outfit or with a monumental continuous window. The minimum glass thickness thus becomes 13.06 mm, 16.06 mm or 19.06 mm depending on the window surface.
If laminated with a tempered eraser, you make Bengglas® extra burglar -resistant, soundproofing and falling for it.
Layers with a monumental breeding window are not recommended. Bengglas® is made of extra clear filtered glass. Not the monumental people. This allows you to lose valuable features of the glass for you.
The insulation value remains the same even after laying.
Yes absolutely. It is possible to thicken Bengglas®.
This means that Bengglas® is suitable for every frame. Even where double glazing or triple glass is placed.
In this case an extra cavity including eraser, 8.3 mm, 10.3 mm or 12.3 mm glass package is placed behind the standard. The cavity options amount to 6, 9, 12, 15, 16, 18 or 20 millimeters thick with a break window of 4, 5, 6 or 8 millimeters (depending on the basic construction).
The insulation value remains the same even after thickening (U=0.50).
The delivery time for Bengglas® is currently approximately 12-14 working weeks.
