The roof of the exhibition venue was partially collapsed and insulated with hazardous glass wool, which was floating down into the interior of the building. To rebuild it, wooden beams from a demolished house were used and the roofs were planted. The building was then insulated by using cellulose fiber and waste paper to stuff the 14 cm of hollow space between the roof and the ceiling. The insulation material was waterproofed with mineral salts, which are also fire resistant and keep off vermin. The air from the Varieté Salon and the Café Olé is circulated and heated by an air heat exchanger. All the windows were equipped with insulated glazing. The exterior of the buildings were painted with mineral paint, consisting of natural ingredients such as chalk, curd and linseed oil.
Other buildings, such as the Café Olé, the Wolfgang Neuss Salon and several of the studios are insulated with sheep skin to keep the heating costs low. Sheep skin is a natural, recyclable and healthwise safe insulation material.
The tar roofing felt on all buildings has been replaced in order to plant green roofs, which also contribute to the insulation significantly and help to improve the microclimate on the ufaFabrik’s premises.
The ufaFabrik will continuously extend its involvement in the renovation and enhancement of old factory buildings by using natural materials that are ecologically friendly and do not represent potential health hazards.
