Brief story:
26 Spiralix Vertical RAT3 finned-tube radiators, each 2.5 metres tall, were installed as part of the renovation of a historic commercial building complex on Rosenstraße in Berlin-Mitte. Finished in RAL 1035 Pearl beige, the radiators combine a distinctive industrial form with a warm metallic colour chosen to complement the interior.
The radiators are equipped with remotely controlled electronic valves. One unit was specially adapted to match the existing pipe connections, addressing the practical challenges of upgrading heating in an older building. The tall vertical arrangement brings the characteristic spiral fins into the interior as a visible architectural detail.
The listed commercial buildings at Rosenstraße 16–19 were constructed in 1894–1895 as part of a larger complex. Heinrich Joseph Kayser and Karl von Großheim designed the southeastern section, while Otto March was responsible for the northwestern section. Their large windows, strongly articulated façades and decorative entrances reflect the ambitions of late nineteenth-century commercial architecture. The surviving buildings preserve an important part of central Berlin’s architectural heritage.
