The standing seam system consists of a comprehensive range of robust components that ensures appropriate and correct installation is achieved. It is also important that standing seam roofs are installed by properly trained and equipped professionals. Individual panels are held in place at the top of the pitch by a minimum of 5 fixed clips and then towards the lower portion of the panel by sliding clips allowing thermal movement. These stainless steel clips, which are fixed to the structure, are crimped inside the joints. Thus the fixing clips for panels and flashings never penetrate the material and therefore do not affect the appearance or damage the waterproofing. The low height of the seams (25mm standard) and the 600mm maximum spacing between joints give the roof a light, harmonious appearance. The standing seam system is available in various standard coil dimensions.
