From single glazing to optimal comfort in Zeist
Together with ProGlass, this house in Zeist has been tackled: the old single glass (U = 5.8) has been replaced by vacuum insulation glass from BENGglas (U = 0.40). A significant step forward in insulation, which can be felt immediately. Thanks to BENGglas, the house has not only become more energy-efficient but also quieter and more comfortable. More warmth inside, less noise from outside—without having to replace the window frames. Quite pleasant.

From old HR glass to today's vacuum insulation
In collaboration with Glashandel van Spaendonk, this house in Tilburg has been significantly improved in terms of insulation. The outdated HR glass with a U-value of 2.8 has been replaced with BENG glass with a U-value of 0.40 — that's more than 6 times better insulation. And it doesn't stop at warmth. BENG glass is thin, fits in the existing frames, and also provides more peace at home thanks to excellent sound insulation. This makes sustainability very comfortable.

Upgrade with BENG glass for a monumental building from the 17th century
In the heart of Groningen, this 17th-century monument received a significant energy boost thanks to Glasgilde and BENGglas. No fewer than 97 single-glazed windows (U=5.8) were replaced with ultra-slim BENGglas with an impressive insulation value of 0.40. Thanks to the thin glass thickness of just 8.3 mm, the original frames remained in place — no hassle, just mega results. And as the cherry on top: a significant silence boost with less street noise (-36dB).

New windows, ten times better insulation
Together with Hoskens Schilderwerken, this beautiful building in Leiden has been fitted with vacuum glass from BENGglas. The old single glass, with a U-value of 5.8, has been replaced by super insulating vacuum glass with a U-value of 0.40. This significantly reduces heat loss — and therefore the energy bill.
Nice detail: lightly arched windows were chosen. This way, the original appearance of the building is preserved, while the interior has become much more comfortable.

Homes in Vogelenzang to a higher level with BENG glass
In collaboration with Van Dam Glas & Montage, the first two homes of this beautiful complex in Vogelenzang have been equipped with vacuum glass from BENGglas. The old double glazing (thermopane) has been replaced with glass that has a U-value of 0.40 — and you will notice the difference. Less heat loss, a more favorable energy label, and lower heating costs.
Comfort also gets a significant boost. BENGglas standardly dampens up to 36 dB of sound, and with the laminated variant, this increases to 39 dB. This means: more peace inside, without cold or drafts. And because the glass fits into the existing frames, you don't need to demolish or adjust anything. Quite convenient.

House in Dwingeloo ready for the future with BENG glass
Together with Schildersbedrijf Donker, this house in Dwingeloo has been fitted with vacuum glass from BENGglas. This has replaced the old single glass with a U-value of 5.8 with glass that scores up to 0.40 on insulation — a significant step forward. Good for the energy label and for the wallet.
The difference is also noticeable in terms of comfort. Thanks to vacuum technology, not only is heat loss limited, but also noise from outside. BENGglas standardly dampens up to 36 dB. If you choose the laminated variant, it goes up to 39 dB. This way, it stays nice and quiet, warm, and energy-efficient inside — without needing to replace the window frames.
