Abstract
This paper, which is presented in French, discusses mechanically fastened flat roof systems and metal decking. The Belgian Roofing and Waterproofing Assn is currently writing a "Note of Technical Information" together with the Belgian Building Research Institute. It targets roof contractors and designers in order to help them choose an appropriate mechanically fastened flat roof system. The maual starts with a description of the different metal deck types on which the insulation and roof membranes can be mechanically applied. Particular attention is pad to those conditions that call for a vapor barrier in the flat roof design, a how to choose and install it. The choice and combination of the insulation, of the roofing membranes and of the various types of fasteners and fasteneing is studied in detail. Based upon an important study about wind resistance of the different componenets of the roof assembly, the designer learns how to calcuate the number of mechanical fasteners needed. Several very practical case studies show the designer how to proceed for different flat roof sysems and explain the best way to fasten the insulation and the membranes. New tests and methods of calculation were developed in the study leading to this new technical note. This presentation gives an overview of the new manual and highlights some specific and original findings of it.
