Diligentia is a theatre located on a historic street in the heart of The Hague. The restoration of this listed building, dating from 1645, faced certain constraints, notably because the original wooden frames could not be replaced. That is why FINEO vacuum glazing was chosen for its restoration. Thanks to its slim profile, it can be easily fitted into most existing frames. A total of 104 FINEO units were installed in the original wooden frames, which were then restored. In order to best preserve the building's unique aesthetic, the FINEO Heritage version with its traditional drawn glass finish was chosen. As effective as triple glazing, FINEO has also enabled this building to improve its thermal and acoustic insulation for optimal comfort. Today, the Diligentia has been completely restored thanks to FINEO and now enjoys improved energy performance while retaining its unique charm.
