Detached home in Dortmund: Reference objects


The extraordinary roof of this modern detached home in Dortmund was fitted with various PREFA aluminium products. The majority of the roof landscape was covered with the DS.19 roof shingle. PREFALZ was chosen for the uppermost part of the roof. Both roof systems, as well as the associated roof drainage system, are in the colour P.10 anthracite.

The house was also equipped with a large-scale photovoltaic system. Adapted to the respective roof system, the appropriate solar mounting systems from PREFA were used to generate environmentally friendly electricity. The Vario solar mounts were used on the DS.19 roof shingles. PREFALZ Vario solar mounts were installed on the standing seam sheets.
