Together with Proglass, this beautiful villa has been made more sustainable with BENG glass. The old single glazing (U=5.80) has been replaced with glass that has an impressive insulation value of U=0.40. This way, the original frames are preserved and energy consumption is significantly reduced. A beautiful combination of character and comfort!

This building in Windesheim has been around since 1634 — and before that, it was even a monastery and brewery from 1300. Now the church is getting a major makeover according to the Multi-Year Maintenance Plan: the masonry is being refreshed, wall anchors are being sprayed, and the doors are getting a new coat of paint.

But the real showstopper? The sexton's house is equipped with BENGglass vacuum glass. The old single glazing with a U-value of 5.8 has been replaced by super smart BENGglass Double Coated with an insulation power of just 0.40. And all this in an ultra-thin 8.3 mm thickness that fits perfectly in the existing frames — without any hassle or fuss.

And the best part? The restoration of the imposing oak church tower is scheduled for 2026. 

Together with Proglass, this monumental villa in Baarn has been equipped with BENG glass. The old single glass (U=5.80) has been replaced by vacuum glass with an insulation value of only 0.40 — a world of difference. On the ground floor, the choice was made for the slim 8.3 mm glass, and in places where extra safety was needed, laminated glass was applied. This way, the authentic appearance is preserved, but it is much more comfortable and energy-efficient inside.

Together with the Kralingsche Glashandel, this beautiful building received a significant insulation upgrade with BENGglas. The old single glass (U=5.80) was replaced with vacuum glass with a U-value of 0.40. That means: less heat loss, a lower energy bill, and more living comfort — without changing the authentic window frames. A smart step towards the future.

In collaboration with Martin de Boer, this building received a significant upgrade with BENG glass. The old single glazing (U=5.80) was replaced with vacuum glass with a U-value of 0.40. This significantly reduces heat loss and the energy bill. The authentic window frames could remain in place — so no demolition work, but much more comfort. Exactly how you want it.

At this monument on the Oxerhof Estate, the glaziers from Bosch en Nagelhout are busy with a significant upgrade.

All old windows are being replaced with BENGglas vacuum glass of 8.3 mm with a super low U-value of 0.40. First, they made perfectly fitting templates of all arched windows on-site, which they then digitized and put into production. The result? No more condensation on the inside, top-notch insulation against heat and sound, and all of this without adjustments to the frames.
