Built in 1756, this school was converted into a community centre. The task was to integrate three very different, separate functional areas into the structure of an old half-timbered building, while meeting all the present requirements on structural safety, noise insulation and energy optimisation.

The flat roof of the “Federsee museum” in Bad Buchau, Germany, was refurbished in five work processes. Only a few hours were allowed between removing the old bitumen layers and installing the new layers. Therefore, only Linzmeier’s insulation for gradients was an option for the converters: high-performance insulation material; low weight, therefore no structural issues; low structure height, therefore no need for raising the existing fascia; quickly installed without the need for numbering; with ridge-and-valley boards for highly precise channelling to the water discharge.
