Method of making a wall system

A construction method, said method comprising the steps of:

• providing a first corrugated galvanized steel decking panel and a second corrugated galvanized steel decking panel, each of said panels comprising:
• a top and a bottom defining a length there-between, said panel having a first side and a second side defining a width there-between, said panel having a first face and a second face, said panel having a number of ridges and channels parallel to said panel's length, said ridges and channels in said first face and said second face, wherein insulation is placed in at least one of said channels, said first side defining a first tongue and said second side defining a first groove, said first tongue for interlocking with the groove of a second panel, said first groove for interlocking with the tongue of a third panel, wherein said grooves have a tip and wherein a backer rod of compressible material is placed on said second face adjacent said tongue so that through the interlocking of said panels said tip compresses said backer rod thereby forming a seal, a piece of wood cement board stock attached to said first face of said decking panel by screwing a plurality of screws through said board stock and into said decking panel;
• attaching said the second face of said first panel to the steel frame of a building, said first panel second face facing toward said steel frame, said first panel first face facing generally away from said steel frame;
• attaching said the second face of said second panel to said steel frame of said building, said second panel second face facing toward said steel frame, said second panel first face facing generally away from said steel frame, whereby the tongue of one of said panels interlocks with the groove of the other of said panels;
• and
• attaching a decorative outer surface treatment to said first panel first faces.
