Sandwich Panels​​​

SANDWICH PANELS

Special aluminium clips have to be used for joining the Kalzip® profiled sheets with the substructure of the roof. They are locked into the seam and will be overlapped by the following Kalzip® element, so that the fixing elements are hidden under the roofing. This ensures that the roofing elements need not to be punctured for fastening. The newly developed E clip even improves the as such excellent sliding properties of the Kalzip® roofing. The Kalzip advanced E clip is a steel reinforced GFRP clip that is available in 20 mm height increments, up to a maximum of 180 mm Kalzip® meets current-day requirements in a special way: • Lightweight • Great strength • Resistance • Corrosion-proof • Practically maintenance-free • Resistant to atmospheric effects • Flexible shape • Non combustible • Can be used as lightning conductor • Can be re-usable • High quality material • Can be recycled • Can be re-used, maintaining full functional quality
