The project in brief

In Norway there are many very old churches made in stone and wood. Some of these are many hundred years old and are therefore classified as cultural heritage in need to be protected from damage including fire damage. Fires in churches has happened due to failures in old electrical installations and due to lightening stricking them, but the latest risk is arsonist igniting the churches from the outside on the facades.

It was for two old and very famous wooden churches located in Porsgrunn, decided that a fixed firefighting system was to be installed in them, however sadly the one church was subject to arson before it was protected. This raised a lot of focus on the other church, being the Vestre Porsgrunn Church, and the need for a robust, reliable and well tested system being able to perform both indoor as well as outdoor. VID Fire-Kill luckily had a solution for indoor and outdoor protection of such structures which matched all the criteria. A facade system for the outdoor protection and Model N-pipe and Model APS for the indoor protection.

Why was a VID Fire-Kill solution chosen?

– The solution was successfully tested and verified to such risks found in wood churches and on wooden facades,

– The system could be used in non-heated areas such as in attics and for the facade protection,

– The system, having very small dimension pipes, created minimal need for modification of the church structure,

– The small nozzles and special aesthetical designs ensured hidden installations,

– In case of fire and activation, less water damage would be caused,

– Due to the small need for pressure and flow, the pump room could be installed in closets, small toilets, etc.

Some specifics

The horizontal protection of the church room was fitted with small dimension Model APS – Atrium N-pipes being able to protect the entire room from one side. Attic and tower protection was made with Model N-pipes type 2V and Model APS – KIP, and the outdoor protection was made with Model APS – Facade. All systems where connected to VID Fire-Kill Model C-EL deluge valves.
