At Groot Hertoginnelaan 30 in Bussum, Proglass worked together with contractor Eveloc on a special project: villa Zonnekamp. This beautiful villa is a municipal monument with a rich history and a unique location at the edge of the forest.

For this project, Proglass installed no less than 132 BENGglas Extra Clear windows. To maintain the authentic appearance, the frames were carefully milled out so that the original interior bars could remain. Then the new windows were installed and fitted with a sleek new bar division, which they expertly glued and sealed.

The result: modern comfort and top insulation, while the classic charm of the villa remains completely intact.

Villa Zonnekamp is thus an example of how Proglass knows how to combine traditional craftsmanship with contemporary quality and innovation.

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.

Proglass has once again made a beautiful building more sustainable with BENGglas – this time together with Evident Bouw, in the middle of the historic city center of Amersfoort. The result? So impressive that the neighbors immediately submitted a request as well.

The residents now enjoy noticeably lower energy costs and maximum living comfort. Silence in the house, a delightful indoor climate, and that all year round.

In this hotel, BENGglas was chosen as a sustainable solution for roof glazing. A smart choice, because vacuum glass offers unique advantages here:

BENGglas retains its excellent U-value, even when placed horizontally, is thin and lightweight allowing for lighter roof constructions, and does not experience a decline in insulation value over the years. With an expected lifespan of 50 years, this is the solution for those who want to invest in the future.

The monumental Town Hall of Veere has also received a sustainable upgrade. The old single glass (U=5.8) has been replaced by BENGglas with a U-value of 0.40 — more than ten times better insulating. By fitting it into the existing frames, the historical appearance is fully preserved, while the building is ready for the future. A great example of how BENGglas contributes to sustainability with respect for monumental value.

BENGglas, more than just for monuments
At Domesta and Lennips Group Property Maintenance, vacuum glass also proves its strength. While it is often thought that BENGglas is only suitable for monumental buildings, this project shows that it is also perfectly applicable in apartment buildings and other residential buildings.

The old glass is replaced by BENGglas with a U-value of 0.40 — up to ten times better insulating. Thanks to its slim construction, it fits effortlessly into the existing frames without changing the appearance. This way, every building is ready for the future, from monuments to social housing.
