Monumental customization in Assen: XXL window with BENG glass

In Assen, Schildersbedrijf Donker has measured the glass for a beautiful job on a monumental building. Eye-catcher? An impressive pane of nearly 2,500 x 2,000 mm at the front.

BENGglas with a single coating was chosen — color-neutral in appearance, but with a very strong insulation value of U=0.40.

Maximum comfort while retaining existing frames

This property in Meppel shows what BENG glass Double Coated can do. The complete glazing was carried out by Schildersbedrijf Donker and immediately provides noticeably more peace and comfort in the house. With a U-value of (U=0.40), light solar control properties and a noise reduction of up to -36dB, the indoors is quieter, more pleasant and more energy efficient than ever.

Wederom een prachtige boerderij die klaar is voor de toekomst – duurzaam én stijlvol met BENGglas!

Erker in Meppel verduurzaamd met BENGglas

In samenwerking met Schildersbedrijf Donker is deze prachtige erker in Meppel verduurzaamd met BENGglas – en dat merk je meteen.
Het oude enkelglas (U=5,8) maakte plaats voor ultradun vacuümglas met een indrukwekkende isolatiewaarde van U=0,40. Het resultaat? Een flinke besparing op de energierekening én meer comfort in huis.

Dankzij de dunne opbouw kon het glas gewoon in de bestaande kozijnen geplaatst worden. De authentieke uitstraling van de erker bleef dus volledig behouden. En met een geluidsdemping van 36 dB is het nu ook heerlijk stil binnen.

Sustainability of the house in Dwingeloo with BENGglas Double Coated

Monumental building in Zwolle is ready for the future

Together with Schildersbedrijf Donker, this monumental house was prepared for the future.

The first floor had single glazing (U=5.8), and the ground floor had old-fashioned thermopane (U=2.8). These have all been replaced with super-smart vacuum glass from BENGglas with a U-value of 0.40.

The result? Much warmer in the winter, cooler in the summer, and a lower energy bill. And the best part: the character of the building remains beautifully intact.

Fresh upgrade for a detached villa in Meppel

This detached house in Meppel received a significant insulation boost with BENGglass Double Coated. The old insulating glass (U = 3.0) has been replaced with vacuum glass with a U-value of 0.40 – a huge step forward compared to HR++ or even triple glass.

Interesting detail: condensation now occasionally forms on the outside of the glass. That might sound strange, but it's actually a good sign. The better the glass insulates, the sooner outside condensation occurs. A subtle but visible proof that it works.

Layered vacuum glass for silence and warmth

In this house in Steenwijk, 27 panes of layered BENG glass have been installed – a significant step forward in both thermal and sound insulation. The applied vacuum glass has a U-value of 0.40, thanks to the vacuum between the two glass panes. This means that hardly any heat is lost, and sound is largely kept out as well. Normally, vacuum glass already offers a sound reduction of 36 dB, but in this case, a version with a layered counter pane was chosen. This raises the sound insulation to an impressive 39 dB – noticeably quieter, both during the day and at night.

From single glazing to top insulation in Veenoord

Together with Schildersbedrijf Donker, this house in Veenoord has been significantly upgraded with vacuum glass from BENGglas. Where there was previously single glazing (U = 5.8), glass with an insulation value of 0.40 has now been installed — that's more than ten times better!

Not only does the house heat up less quickly in the summer and cool down more slowly in the winter, but the noise from outside is also significantly reduced. And the appearance? It has remained as it was. With attention to detail, the original profiles and the drip sill have been neatly restored. This way, the appearance remains familiar — but the comfort feels like new.

House in Dwingeloo ready for the future with BENG glass

Together with Schildersbedrijf Donker, this house in Dwingeloo has been equipped with vacuum glass from BENGglas. This 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 in comfort is also noticeable. Thanks to the 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 remains nice and quiet, warm, and energy-efficient inside — without having to replace the frames.

Monument in a new guise, without it being noticeable

Together with Schildersbedrijf Donker, this monumental house has been fitted with BENGglas vacuum glass. The old single glass of only 4 mm thick has been replaced by glass that insulates more than ten times better – without adjusting the original frames.

In addition to a significant leap in energy efficiency, BENGglas also provides more tranquility in the house, more comfort, and more daylight. And all this without changing anything about the familiar appearance of the house.

Character retained, comfort added

Together with Schildersbedrijf Donker, this house in Blokzijl has been fitted with BENG glass with a U-value of 0.40. This makes the house ready for the future — without losing its authentic appearance.

The living room is equipped with 6 windows with adhesive bars. This looks classic, insulates better than separate panes, and is more favorable in price. Heat and noise will stay outside from now on. Quite pleasant!

Direct comfort in a monumental jacket

Together with Schildersbedrijf Donker, this monumental rear facade in Meppel has been tackled — and how. The old single glass (U = 5.8) was replaced by BENG glass (U=0.40), supplied on behalf of Unistone Real Estate BV. The appearance remained the same, but inside it immediately felt different: after just one night, the resident noticed the difference.

Old-fashioned steel, now super well insulated

In collaboration with Schildersbedrijf Donker, we have given these steel frames a significant upgrade. The residents did not want new frames, but they did want more comfort. Thanks to the slim BENGglas (only 8.3 mm thick), the glass could simply be placed in the existing rebate — despite the limited space of only 10 mm.

With a bit of smart finishing in sealant, the edge and absorption strip were neatly concealed. Then the frames were repainted. The end result? The original appearance remained exactly as it was — but inside it is now pleasantly warm and quiet. You can't even hear the neighbor's radio anymore.

Once again, a farmhouse ready for the future!

This farm in Wapse was ready for something new. The old windows let in moisture and the cold came in as if it were nothing. Time for action, then — and it came, together with Schildersbedrijf Donker.

All windows have been replaced with BENGglas. The result? No more leaks, but a warm, quiet home. And a nice bonus: everything fits perfectly into the existing frames, so the characteristic appearance is just as it was.

Smartly renovated. Ready for the future.

BENG glass with cross rod retains character appearance

This project in Wezup shows how you can use BENG glass Single Coated to smartly make your home more sustainable, without losing the character of your home. Outdated insulation glass with a 9mm cavity and single glass have been replaced by one high-quality pane with a U-value of (U=0.40). You notice the difference immediately: more peace, more warmth and a more pleasant indoor climate. To achieve this result, the cross bars on the outside were temporarily removed. This allowed one window to be installed, after which new cross bars were replaced. The familiar appearance was retained, while thermal bridges at the cross bars disappeared. A smart intervention with a major effect on comfort and energy consumption. The glazing was expertly done by painting company Donker. The result is a house that is ready for the future, with visible preservation of detail and tangibly more living comfort - every day.
