A DESIGN:

Design Aluminium composite panel (ACP) cladding system to withstand a designwind 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- 4mmthick ensuring the product has fire resistance rating properties. Design framingsystem with gap not more than 150 mm between wall & cladding.

Movement: System shall be designed to accommodate movement due to anyforce including movement resulting from exterior skin temperature (15°C to85°C) & also to accommodate horizontal building movement of 10 mm per panel& vertical movement of 20 mm between floors on Al framing system withsupport brackets, gaskets & fastening devices. System shall be designed toaccommodate size & shape of ACP as per approved drawings including approvedmodifications as may be required during execution as well as all other incidentalforces & stresses likely to be experienced under service conditions, i.e., Lateralforce, Dead weight & Thermal expansion due to building movement bothvertical & horizontal etc.Groove width in system both in horizontal & vertical shall not be more than 18mm. Grooves shall be designed to accommodate non-staining weather sealantof approved make.
