Making the monumental building Weurt more sustainable
The single glass – with a U-value of 5.8 – has been replaced here by hardened vacuum glass with a U-value of no less than 0.40. As a result, the glass insulates a factor of 14 better and the residents will save considerably on the gas bill.
Where the single glass was still placed with putty, the BENGglas placed in the Monustop to maintain the authentic appearance.
Nice details here are the various bar windows and the compartments of vacuum glass.
