General

BENGglas is not ordinary glass – it is a revolutionary solution for sustainable and future-proof building. Compared to standard insulation glass, BENGglas offers unique advantages that directly improve both your home and the climate.

• Superior insulation: with a U-value starting from 0.35 W/m²K, BENGglas is twice as effective as triple glazing (0.70) and even three times better than double glazing (1.10). This means significant energy savings and lower heating costs.
• Long lifespan: while traditional glass lasts an average of 25 years, BENGglas lasts up to 50 years. Produce once, less CO₂, and half a century of benefits!
• Sustainable and environmentally friendly: thanks to less material use (30% less glass than triple glazing), BENGglas saves thousands of tons of CO₂ annually. This way, you actively contribute to a cleaner planet.
• Light and thin: at only 8.3 mm thick, BENGglas fits in almost any existing frame and allows for lighter hardware, making construction sustainable and efficient.
• A true climate hero: if all of the Netherlands switches to BENGglas, we can save up to 4.1 megatons of CO₂ annually — that's equivalent to 170,000 car trips from Amsterdam to Paris! Moreover, the production of BENGglas alone results in 24,000 tons less CO₂ emissions per year.
• A smart investment in the future: less energy consumption, less maintenance, and a longer lifespan make BENGglas a choice that benefits you for years – for yourself and for future generations.

In short: with BENGglas you choose maximum energy efficiency, sustainability, and a smart investment in the future. Make a difference, for your home and for our planet.

Because you don't just buy glass, but a future-proof solution that really saves money and energy. BENGglas has an insulation value starting from 0.35 W/m²K — that's 2x better than triple glazing (0.70) and even 3x better than double glazing (1.1). Less heat loss immediately means lower heating costs. This also means a better energy label and therefore a higher property value. The effective payback period is often 0 years.

But that's not all. BENGglas lasts up to 50 years, while standard glass typically needs to be replaced after 25 years. Invest once, and you're set for two generations. That means less maintenance, less replacement, and thus lower total costs.

The environment also benefits: if the whole of the Netherlands switches to BENGglas, we save no less than 4.1 megatons of CO₂ annually — comparable to 170,000 car trips from Amsterdam to Paris. Less CO₂ emissions and a lower energy bill: that's what we call an investment that pays for itself.

In short: with BENGglas you invest in sustainability, comfort, and financial savings. Smart, right?

Single glazing? That will soon be a problem.
The court in Amsterdam has ruled that single glazing in rental properties can be considered a defect. This could have significant consequences for at least a million homes in the Netherlands. In the case of this ruling, the landlord had to install double glazing within four months or reduce the rent (Telegraaf, 2024).

Fortunately, there is a smart solution:
BENGglas fits into existing frames, even if they currently have single glazing. This way, you can easily replace the glass with insulation glass that insulates up to twice as well as triple glazing — without the hassle of new frames.
For landlords who want to comply with the rules and make their properties more comfortable, BENGglas is a smart and sustainable choice.

Vacuum glass was first patented in Germany in 1913. However, it took until 1996 for the first commercial products to appear — originating from Japan and South Korea. These early versions were still limited in use and not suitable for broader applications in construction.

The real breakthrough came in 2016, when LandGlass became the first in the world to market a fully tempered, tested, and certified vacuum glass: LandVac®. Since then, the technology has rapidly evolved — resulting in high-quality, reliable, and durable titanium vacuum glass.

In 2019, Fineo (from AGC) followed, intended for lighter applications. But those who choose maximum performance in terms of insulation, safety, and durability opt for LandVac.

BENGglas is the exclusive importer of LandVac in the Netherlands, Belgium, and several other European countries.
