Connecting with a fell seam

It is essential to use the fell seam technique for connecting adjoining Cuprotect® sheets in order to obtain an RF-impenetrable and equally conductive surface. In 05/2005, a patent has been applied for this connection technique at the German Patent Office, ref. no. 10 2005 023 344.9, as well as at the European Patent Office, ref. no. 07 019 249 and US Patented

In openings like windows and doors, the Cuprotect® mesh shall be bent around the corners into the opening by at least 300 mm and minimum the depth of the reveals. Until the work for the connection to the window continues, the mesh shall be tacked to the reveals enabling the connection between wall shielding and window/door frames without any gaps. We recommend shielded timber or aluminium clad timber frames from Ziegelmeier


At the gable, the mesh shall be carried around under the overhang and fixed, with an additional 20 - 30 cm along the roof line to allow for an overlapping connection with the roof shielding. In case of the roof being prefabricated in a workshop (prefabricated houses), the shielding layer of Cuprotect® shall be placed immediately underneath the rafters using the fell seam technique.

The long sides are prefolded by 4 cm. They shall be unfolded, hanged into each other and fastened together to form a fell seam. The mesh shall be fixed to the rafters using stainless steel staples at a maximum distance of approximately 5 cm.

Furthermore, the instructions for the penetration of the shielding shall be obeyed.

Cuprotect® shall be connected directly to the earth busbar at least once on each side of the building. The cross-section shall comply with DIN VDE (recommends a minimum of 10 mm²). The network type shall correspond to the German TN-S or TT network. The electrician in charge of the works is liable for the earthing.
