80 windows further — and much better insulated
Together with Bosch & Nagelhout B.V., this house in Nunspeet received a significant upgrade. The old HR++ glass (U = 1.10) was replaced with BENG glass with a U-value of 0.40. In total, no less than 80 windows were replaced — good for more comfort, lower heating costs, and a leap in the energy label.

Immediate comfort in a monumental guise
Together with Schildersbedrijf Donker, this monumental rear facade in Meppel has been tackled — and how. The old single glazing (U = 5.8) was replaced with 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.

BENG glass with lead division - authentic look - modern performance
Glazier Kok Renkum gave this 1930s house a smart upgrade with BENG glass (U=0.40). By applying a lead division in the transom windows, the classic look is preserved — but inside it is now comfortable and well insulated. Less draft, less noise, yet the charm of the past.

Monument renovated, comfort maximized
In collaboration with Eekhuis, this monumental house is equipped with BENG glass with a U-value of 0.40. The old glass was replaced by slim vacuum glass that fits perfectly into the existing frames. This way, the character of the house is preserved, but inside it is now much warmer, quieter, and more comfortable. Once the painter finishes the finishing touches, these frames will look completely new again!
Smartly renovated with vacuum glass in Zaandam
Together with Van Dam Glas & Montage, this house in Zaandam has been fitted with BENGglas with a U-value of 0.40. The old glass was replaced with slim vacuum glass, without the need to adjust the frames. This means: better insulation, more comfort, and a step forward in energy-efficient living — without major renovations.

More comfort without new window frames
In collaboration with Van Dam Glas & Montage, the living room of this beautiful property has become much better insulated. The old single glazing (U = 5.8) has been replaced by BENGglas with a much better U-value of 0.40. The existing frames could remain in place, as the new glass is only 8.3 mm thick. Extra nice: it is now also much quieter inside, thanks to a noise reduction of 36 dB.
