Together with Proglass, this beautiful villa has been made more sustainable with BENGglas. The old single glazing (U=5.80) has been replaced with glass boasting an impressive insulation value of U=0.40. This way, the original window 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 Long-Term 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 BENGglas vacuum glass. The old single glass with a U-value of 5.8 has been replaced by super-smart BENGglas Double Coated with an insulation power of just 0.40. And all this in an ultra-thin 8.3 mm thickness that fits perfectly into the existing frames — without any hassle or fuss.

And the best part? In 2026, the restoration of the imposing oak church tower is scheduled.

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

Together with Kralingsche Glashandel, this beautiful building received a significant insulation upgrade with BENGglas. The old single glazing (U=5.80) was replaced with vacuum glass with a U-value of 0.40. This 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. That 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 as you want it.

At this monument on Landgoed Oxerhof, 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 created precisely fitting molds of all arched windows on-site, which they then digitized and put into production. The result? No more condensation on the inside, top insulation against heat and sound, and all this without modifications to the frames.
