Rugo, Luxemburg

RETROFlex in non-ventilated double-skin facade. For maintenance purposes, the inner facade is equipped with openable windows. The inner facade and the RETROFlex blinds are segmented, the outer glass panes are curved.

The openable cavity to the interior is a major challenge in terms of impermeability to water vapour diffusion. There is a risk of vapour diffusion and thus moisture migration due to a vapour pressure gradient between the interior and the facade cavity. The moisture is then deposited on the inside of the baffle plate.
