SHEET LAYING

In order to ensure a watertight skin to the building, it is essential that the correct installation and fixing procedures are followed. To prevent the ingress of driving rain, side laps should be sealed and face away from the prevailing wind.  In all cladding applications adequate end lap is critical. For roofing applications, the end lap is largely dependent upon the roof pitch. Please refer to the table below for guidance.

FIXING

Primary fasteners should be fixed through the centre of every other valley at each purlin, except at end laps where fasteners should be placed in every valley. All holes should be drilled and not punched and resultant swarf removed.            

It is important to ensure that correct tightening torque is applied to the fastener to obtain maximum sealing and holding action. The above details are based upon experience, however sheeting contractors may adopt their own fixing methods but the Health and Safety Executive requirements must be satisfied.
