The advantages of the snow retention systems by clamping-method are that no screw will damage or penetrate the roof layer. The power flux of the snow tension is passed on to the wooden substructure (boarding and rafters) via the seams and fixing clips. Therefor, the snow retention brackets should be installed on every single standing seam.
Some important and necessary considerations for planning and mounting of snow retention systems have to be made to ensure a functioning system.
Following data are necessary to determine the dimension (number of rows, distance of the brackets, single or double tube) of the snow retention system:
Specific snow load (depends on location, according to DIN 1055/5, or indication of the engineer engaged in statically calculations), roof pitch, shape and dimension, type of roofing, seam distance, special factors such as wind motion etc..
