In the heart of Hattem, Bosch & Nagelhout chose BENGglas® to make this National Monument from 1626 more sustainable. This prepares the building for the future without compromising its historical appearance.

Because BENGglas fits in the existing window frames, the original appearance was preserved. At the same time, comfort and energy performance have been significantly improved. A fine example of how modern insulation glass makes monumental buildings future-proof.

In Laren, a remarkable monument has been preserved in a way you rarely see: BENGglas® combined with stained glass. In consultation with the monuments commission, Bosch & Nagelhout beautifully designed this project and in their own workshop provided both the interior and exterior panes with lead. After installation, everything was carefully patinated, giving it that authentic, weathered appearance right away.

In total, more than 70 windows have been replaced, from single glazing to vacuum glass with a U-value of 0.40. This significantly reduces energy demand while preserving the monumental appearance.

This project shows that sustainability and heritage conservation can go hand in hand – even in places where you wouldn't immediately expect it.

Bosch en Nagelhout has given this beautiful villa a significant upgrade with BENGglas vacuum glass, featuring a top insulation value of 0.40. No less than about 100 windows have been replaced with the super smart BENGglas Double Coated.
For the authentic stained glass, smart secondary glazing was chosen, so the ambiance of the house is preserved without compromising on insulation.

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 The old single glass with a U-value of 5.8 has been replaced by super-smart BENGglas Double Coated with an insulation power of just 0.40.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.

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.

Together with Bosch & Nagelhout B.V., this house in Nunspeet received a significant upgrade. The old HR++ glass (U = 1.10) was replaced with BENGglass with a U-value of 0.40. In total, no less than 80 panes were replaced — resulting in more comfort, lower heating costs, and an improvement in the energy label.

Bosch & Nagelhout gaf bij de oude historische ingang van het dierenpark een prachtige woning een flinke upgrade met BENGglas vacuümglas. Het ultradunne glas (8,3 mm) met een U-waarde van 0,40 past perfect in de originele kozijnen, waardoor de isolatie flink verbetert zonder afbreuk te doen aan het historische karakter. Tegelijkertijd werd het authentieke glas-in-lood vakkundig gerestaureerd, zodat de charme van het pand volledig behouden bleef. Deze slimme combinatie van behoud en innovatie leverde een mooie vermelding op in het vakblad SchildersVAK.
