Making BENGglas BASIC additional windows more sustainable
In collaboration with Koek & Reinders Schilderwerken, this monumental building in The Hague is taking a big step forward in its thermal insulation.
The old-fashioned single glazing has been replaced here by vacuum glass from the BENGglas . This reduces the U-value of the glass from 5.8 (single glazing) to no less than 0.58 ( BENGglas BASIC ). This means that the windows have insulated no less than ten times better.
Because BENGglas is very thin (here 8.15 mm), it always fits in the existing frames and the authentic appearance is preserved. A nice detail is the slightly arched shaped window.
Finally, the vacuum glass here also offers optimum sound insulation for the relatively busy street. In the thinnest version (8.15 mm) the sound reduction is already dB=36. With the layered variant, the attenuation would amount to no less than dB = 39.
