A DESIGN:
Design Aluminium composite panel (ACP) cladding system to withstand a design
wind pressure of 125 kg/m² upto two floors for external surface of any profile,
linear or curvilinear, with approved make, size, shade & texture of ACPs- 4mm
thick ensuring the product has fire resistance rating properties. Design framing
system with gap not more than 150 mm between wall & cladding.

force including movement resulting from exterior skin temperature (15°C to
85°C) & also to accommodate horizontal building movement of 10 mm per panel
& vertical movement of 20 mm between floors on Al framing system with
support brackets, gaskets & fastening devices. System shall be designed to
accommodate size & shape of ACP as per approved drawings including approved
modifications as may be required during execution as well as all other incidental
forces & stresses likely to be experienced under service conditions, i.e., Lateral
force, Dead weight & Thermal expansion due to building movement both
vertical & horizontal etc.
Groove width in system both in horizontal & vertical shall not be more than 18
mm. Grooves shall be designed to accommodate non-staining weather sealant
of approved make.
