Fire-resistant glass with maximum insulation
BENGglas combined with Pyroguard delivers fire resistance and outstanding insulation in a single solution. The glass resists fire, smoke, and heat for up to 60 minutes, maintaining its stability so occupants can escape safely while protecting the property.
Key benefits:
- Superior insulation — U-value as low as 0.35, up to 3× better than standard double glazing.
- Fire resistance of 30 or 60 minutes (EW/EI) — independently tested and certified.
- Slim and safe — from just 15 mm thick, with fall-through and injury safety.
Custom-made for every application
Fire-resistant glass must always comply with an official test report. For tailored advice and a quote, contact us directly at info@bengproducts.nl.
The perfect combination of fire retardancy and top insulation
Traditional fire-resistant glass often compromises on insulation performance — but with fire-resistant vacuum glass, that’s a thing of the past. Thanks to advanced vacuum technology, the U-value remains exceptionally low, down to 0.35. This unique combination is ideal for projects where both safety and energy efficiency are essential — such as factory halls, healthcare facilities, or office buildings.
Many office and commercial building facades are already fitted with fire-resistant glass, but still require sustainability upgrades because the existing glazing is insufficiently insulating (double glazing: 1.10 – triple glazing: 0.70). With BENGglas, you significantly improve insulation without compromising on fire safety.
A revolutionary product for facade (renovation)
For facade applications, BENGglas offers a revolutionary glass product with EW30 or EW60 classification. This ultra-thin glass package of 15 mm combines a U-value of 0.35 W/m²K with double-sided injury safety and fall-through safety according to NEN 2608.
Ideal for both new construction and renovation. Many facades of offices and commercial buildings are already fire-resistant but require sustainability improvements because the current glazing does not insulate sufficiently. With BENGglas, you improve insulation without compromising on safety.
The application of fire-resistant glazing is regulated by law
Under the Decree on Buildings in the Living Environment (Bbl), there is a requirement for Resistance to Fire Penetration and Fire Spread (WBDBO) between two fire compartments.
- Fire Penetration
This refers to fire spreading from one room to another via internal walls or ceilings — not through the outside air. The fire resistance of these partition structures is determined according to NEN 6069 (as referenced in NEN 6068). - Fire Spread
This refers to fire spreading through the outside air to another room. The assessment is carried out according to NEN 6068, which determines the resistance to fire penetration and fire spread between spaces.
BENGglas and Pyroguard
BENGglas can be combined with the fire-resistant glazing of Pyroguard, a leading manufacturer of fire-safe glass.
With this hybrid construction, EW and EI classifications of 30 or 60 minutes are possible, always supported by a valid test report.

Frequently asked questions
What are the benefits of vacuum glass?
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!

What is the U-value and why is it important?
The U-value indicates how well glass insulates. Simply put: the lower the U-value, the better the glass keeps heat in in the winter - and out in the summer. So you save on your energy bill and increase your living comfort.
The U-value is influenced by many factors, such as:
- The coating on the glass
- The filling between the glass layers (e.g. air, gas or vacuum)
- The cavity width - i.e. the space between the glass layers
How well does BENG glass score compared to other types of glass?
Here is an overview of the average U-values per type of glass:
- Single-glazing: 5.8 (insulation? Barely.).
- Double glazing (Thermopane): 2.8
- HR++ glass: 1,10
- HR++ / Triple glass: 0,70
- Other vacuum glass: between 0.45 and 0.70
- BENG glass: from 0.35 to 0.50
In short: BENG glass has by far the best insulation value of all.
So you save extra on your energy bill!
