Preservation of a house
In order to make this house more sustainable, BENGglas provided the entire facade with tempered vacuum glass. As a result the U-value of the glass has been reduced significantly from U=2.8 to no less than U=0.4!
When renovating windows in a house, there is often a limited installation depth in the window frames available. As vacuum glass is very thin (from 6.3mm), it always fits into the existing frames; i.e. the window frames do not have to be replaced.
