Frogner Hovedgaard is listed on the Norwegian Directorate of Cultural Heritage list of cultural heritage sites. The buildings were erected as a wood construction in 1825 – 1830 in Skien in the southern parts of Norway. As a part of the Norwegian cultural heritage, it was decided that Frogner Hovedgaard should be fire protected.
Due to laws and regulation regarding the renovation of such buildings, a system using small dimension pipes was requested and furthermore due to many non-heated areas, innovative systems utilizing watermist deluge systems where required. VID-Fire-Kill Model OH Nozzles for heated areas and VID Fire-Kill Model N-pipes was therefore a perfect match for the project requirements.
