Framedrawing 2

Subsequent to coating each 28 3/4"x 56 1/2"x 1/2" panel with Hydro-2000 (liquid rubber), they are secured to a pressure treated 2"x 4"x 56 1/2" x 2"x 4"x 28 3/4" lap jointed sub frame that was assembled together with waterproof epoxy glue and stainless steel screws.  

Unless your metal framework is perfectly square, (which is highly unlikely), You will have to adjust the treated 2" x 4" sub frame dimensions accordingly. Mine was out of square by 3/16" in a length of 9 ft. 7 inches. This is not catastrophic, and it is easily corrected.

The assembled panels were given an inside coat of liquid rubber at the edges of the 2"x 4" and plywood inner surfaces. This was an extra precaution to insure the Insulation will never get wet (I hope). At this point, I caulked every nook and cranny I could find. The insulation is Dow Corning (pink panther) R factor = 7.5. Obviously, there are a myriad of insulates to choose from, so pick whatever will fit your budget. 

The R factors for this project :  Floor = 7.5, Walls = 5.0, Roof =11
