The structural restoration of this UNESCO World Heritage-listed industrial monument continues to present new challenges. Both unconventional and pragmatic solutions were found, with the Janisol Primo window system used to reconstruct the historical glasswork at this former salt factory.
The insulated window system provided the necessary thermal insulation with very narrow profile views. The striking thing about the solution is the way in which the modern profile was able to stay true to the appearance of the original industrial glazing: Whereas the new windows, made from Janisol Primo, have an offset of just a few millimetres between the profile level and the glass level when viewed from the outside, the offset in historical industrial glazing using T- or angled steel profiles and wire-glass panes with an external putty rebate is approx. 30 millimetres. This solution was developed in close consultation between the architects, the monument authorities and the steel consultant from Schüco Stahlsysteme Jansen and implemented with exemplary craftsmanship by BM-Metallbau GmbH, Lollar.
