Copper setting for a church in Morbihan

Covering an area of ​​850 m², the Saint-Sauveur church, located in the town of Locminé in Morbihan (56), is 10 meters high. It has a fairly complex modern wooden frame with no false ceiling. Faced with an unusual height, the Kervadec company, specialized in water and gas installation work, opted for the installation of a gas boiler with the Viega crimping system for the associated piping network. The goal? Reduce maintenance costs and guarantee increased work safety (risk of fire linked to the glued laminated structure). “Installing the Viega crimping system was the safest and most efficient solution,” explains Jacques Kervadec, CEO of the eponymous Vannes company for 17 years.

An installation made complex by the architecture of the building

Work began in January 2013. Prior to installation, the project manager had to take into account the specificity of the structure. The challenge was to place the piping network at the level of the framework as discreetly as possible in the absence of a false ceiling to conceal it. Equipped with a basket, the installers laid the Profipress G fittings very high, as close as possible to the ridge, with elbows at the level of the radiant heating panels, making them almost invisible from the ground.

250 meters of copper pipe were thus needed for this project at a total cost of 85 euros. The installer mounted pipes with a diameter varying from 000 to 14 diameters using a technique adapted to the specificities of the building, which did not allow recourse to a conventional installation. “With a wooden frame and work carried out at a height of 42 meters, the traditional welding technique would have required permanent and tiring material handling,” notes Bertrand Turpin, account manager at Kervadec. On the contrary, the crimping technology developed by Viega offers a double level of protection and guarantees a durable connection, resistant to torsion and long-term longitudinal forces.

A considerable saving of space and energy

Another advantage is that the natural and progressive patina of copper matches perfectly with the color of the wood. No painting of the piping was therefore necessary. “We saved about 30% time and saved energy. The crimping made it possible to avoid a lot of handling, ”adds Bertrand Turpin. Copper pipes are ideal for renovation sites. They can follow and ideally circumvent all obstacles in an apparent way, as for this site, or else hidden behind a formwork.

Profipress, a very wide range

With more than 800 fittings with variable dimensions from 12 to 108 mm, the Profipress range offers great installation possibilities and various fields of application: from domestic hot water to industrial or naval installations, including certain hydrocarbons, heating, gas and various building applications.
