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.

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 retains heat in the winter – and keeps it out in the summer. This way, you save on your energy bill and increase your living comfort.
The U-value is influenced by various factors, such as:
- The coating on the glass
- The filling between the glass layers (e.g., air, gas, or vacuum)
- The cavity width – thus the space between the glass layers
How does BENGglas 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? Hardly.)
- Double glazing: 1.10
- Triple glazing: 0.70
- Other vacuum glass types: between 0.45 and 0.70
- BENGglas: from 0.35 to 0.50
In short: BENGglas has by far the best insulation value of all.
This way, you save extra on your energy bill!
*U-values measured according to the standards EN 674:2011 and ISO 19916-1:2018 by ift Rosenheim (2025).
