The expansion of base roofing membrane 20 into holes 68 along with the adherence of top membrane 40 to the portions of base roofing membrane 20 sticking up into holes 68 help prevent counterclockwise rotation of plate 60. Counterclockwise rotation of plate 60 can cause fastener 62 to also rotate and possibly unscrew from steel deck 12 and loosen plate 60, which can lead to premature failure of the roofing system.
  • compression V's 69 have a V-shape like the bow of a boat as shown in FIGS. 8 through 10. Other shapes, such as a rounded half dome can be used in place of compression V's 69.

Une telle membrane est constituée d'asphalte modifié par un copolymère de styrène-butadiène-styrène. Chacune des sections de la membrane de couverture comporte deux portions d'auto-adhésif: une première bande longitudinale disposée sur sa surface inférieure (24b), et une deuxième bande longitudinale disposée sur sa surface supérieure (24a), l'une d'elle l'étant le long du côté gauche, et l'autre, du côté droit. Les parties d'auto-adhésif sont constituées d'asphalte modifié par un copolymère de styrène-isoprène-styrène. La première bande d'auto-adhésif placée sur la surface inférieure d'une des portions de la membrane est placée de manière à recouvrir la deuxième bande d'auto-adhésif sur la surface supérieure d'une deuxième portion de la membrane.
