As per Kalzip Ltd standard details and recommendations.

It is important that the structural engineer responsible for the project confirms that the assumed loadings are correct or supplies alternatives in order that the metal deck suitability may be confirmed. 280 ATTACHMENT OF DECKING -Primary fasteners: 5.5 mm diameter carbon steel self drilling fasteners, reference SD-8-T15-5.5 x 25. One fastener(s) to be installed in every valley at each sheet support. Side laps to be stitched in the valley of the profile at maximum 400 mm centres with 4.8 mm diameter carbon steel self drilling stitching fasteners, reference SL2-T-4.8x20. End laps to be stitched...

-End laps: -Side laps: -Spacers -Fasteners: -Thermal insulation: -Vapour control layer: Aluminium Site Welding: No end laps - single length sheets. Kalzip sheets are mechanically seamed over head of support clips with a Kalzip “zipping” machine. Support clips, steel reinforced polyamide Kalzip E-clips type E.180 with S10 spacer pads. 6.0 mm diameter stainless steel torque controlled fasteners, reference SDK3-S-377-6.0x45. Two fasteners per E.clip positioned diagonally opposite in the holes of the base of the clip. NB. The use of curved and/or long length Kalzip sheets (e.g. over 25 m) may require...

223 ISOLATING TAPE: A type recommended for the purpose by the cladding manufacturer.

Cut sheets and flashings to give clean true lines, with no distortion. Remove burrs and any lubricant. Cut openings in sheets for outlets, vent pipes, flues, etc. to the minimum size necessary and as per cladding manufacturer’s recommendations. For double skin construction do not line out building completely before installation of the outer sheets. Lay sheets with exposed joints of side laps away from the prevailing wind unless shown otherwise on drawings. Ensure that the raking cut edges at hips and valleys are fully supported. Remove all drilling swarf, dust, debris and any other foreign matter...
