Because of the uneven substrate different thicknesses of the EPS thermal insulation was used to compensate. As sound insulation and to fix the floor heating pipes a 30 mm Isoroll Typ 4 (glass wool) was used. On the insulation the calicumsufate screed was poured in a thickness of at least 55 mm. Part of the screed was grinded and sealed with a surface protection, part of it was covered with tiles and parquet.

1. Sealed CAF as decorative floor underlined the industrial characteristic of the lofts 2. CAF screeds applied with a mix mobile has very high application speed (up to 2000 m per day) 3. CAF screeds have no long-term shrinkage, what means no sinking of the edges

During 90 years the area of 70 500 m² in Albisrieden served as restricted storage area. Today the storage halls have disappeared. With 800 apartments, 200 student rooms and 7200 m² of commercial space a new district has been developed: the Zurich Freilager. 10 new buildings have been built and on top of the two former warehouses, built in 1926/1927, three additional levels have been built and transformed into apartments. In the former warehouses, the industrial look should be kept. Therefor the architect proposed grinded and sealed calciumsulfate screeds. In the other areas parquet is used.
