Best insulation value

The U-value (insulation value) of BENGglas is 0.4 W/m2-K. A pane of 6.3 mm thick BENGglas therefore has a U-value that is the best in the world.

The U-values ​​of the various types of insulating glass are shown in the table at the bottom of this page.

Noise reduction

Due to the vacuum there is little mutual contact between the 2 glass panes, which not only creates a very good insulation value, but also a very good noise reduction.

Normally, very thick glass is needed to achieve noise reduction with insulating glass. This is not the case with vacuum glass. Even in the thinnest version, a dB value of dB=36 is already achieved.

This dB value can increase to dB=41 with thicker vacuum glass or with the layered version.

In short: noise reduction in combination with a thin structure? This is only possible with vacuum glass with the exceptionally good values ​​of BENGglas .

Hardened

BENGglas is the only hardened vacuum glass in the world. Hardening has several advantages:

• The occurrence of a thermal break is excluded.
• It is five times stronger than untempered glass of the same thickness.
• Official safety glass; can therefore be glazed to the ground (very suitable for e.g. schools).

With regular insulating glass, hardening has an additional cost; at BENGglas this is standard and is included in the price. Naturally, all panes of laminated BENG vacuum glass are also hardened.

Thin & light weight

BENGglas , tempered vacuum glass, is 6.3 mm thick in the thinnest variant and weighs only 20 kg per m2.

Because the glass is so thin, the glass can be used in the existing frames. This saves a lot of time and money. Old glass out, BENGglas in and the house is preserved.

Certainly compared to Triple glass, the vacuum glass is light in weight. Triple glass is often at least 75% heavier. Heavy glass is also considerably more expensive to install and requires more expensive (heavier) hinges and locks.

15 year warranty

BENGglas gives a 15-year guarantee on its products. For regular insulating glass, this warranty period is limited to only 10 years.

The expected lifespan of the vacuum glass is at least 25 years. During this entire period, unlike regular insulating glass and Triple glass, there is no drop in the insulation value. The U-value remains unchanged over the years.

In short, from "day 1 to well into the future" you are assured of an optimal insulation value.

Many options

By varying the individual glass sheets, a product can be put together with various types of vacuum glass that perfectly matches your specific wishes.

Possible variances / options are as follows:

• Extra bright (more light)
• Sun protection
• Laminated inner pane (both panes tempered)
• Oversized: up to 3000mm
• Shaped windows
• Anti-dirt coating
• (In)visible valve
• Printing (screen printing)
• Various thicknesses: 6.3 mm, 8.3 mm, 10.3 mm, 12.3 mm or 16.3 mm
• To be processed with regular insulating glass (“thicken up”)

Micro spacers

All vacuum glass products have micro spacers. These prevent the outer leaf and inner leaf from touching each other due to the suction effect of the vacuum.

BENGglas has the fewest and smallest spacers; up to 6 times less than other vacuum glass products.

The spacers are virtually invisible. Certainly if you stand further than 1 meter from the glass, they are not visible to the naked eye.

No condensation on the inside

When the U value is low, condensation will no longer occur on the inside of the frame.

However, in the "condensation season" condensation can occur on the outside. This will show up around the micro spacers and usually disappears quickly during the day.
