Abstract
Un système de drainage à double niveau pour toiture plate, horizontale ou légèrement en pente, comprenant deux drains, l'un supérieur situé sur le plan supérieur de la toiture au niveau de la membrane d'étanchéité, l'autre inférieur, muni d'un clapet et situé sur le plan de la membrane para-vapeur; un panneau isolant à drainage autonome muni d'un réseau de rigoles en pente uni- ou multi-directionnelle dans sa face supérieure et un réseau de rigoles dans sa face inférieure, lesquels communiquent entre eux par une canalisation au travers l'épaisseur du panneau isolant ou formée aux joints de panneaux isolants juxtaposés; le drain supérieur permet le drainage de l'eau s'écoulant sur la membrane d'étanchéité tandis que les réseaux de rigoles supérieur et inférieur, ainsi que la canalisation et le drain inférieur permettent le drainage hors de la toiture de l'eau infiltrée sous la membrane d'étanchéité
lorsque celle-ci n'est plus parfaitement étanche, évitant ainsi la détérioration de l'isolant et l'accumulation d'eau pouvant entraîner de graves problèmes de surcharge de la toiture. A double level drainage system for roofs flat, horizontal or slightly sloping, comprising two drains, the upper one located on the upper plane of the roof at the waterproofing membrane, the other lower, fitted a valve and located on the plane of the vapor barrier membrane; a self-draining insulation panel with a network of channels sloping uni- or multidirectional in its upper face and a network of channels in its underside, which communicate with each other by a channel through the thickness of the insulating panel or formed at the panel joints juxtaposed insulators; the upper drain allows the drainage of the water flowing over the waterproofing membrane while the upper and lower channel networks, as well as the pipe and lower drain allow drainage out of the roof of infiltrated water under the waterproofing membrane when it is no longer perfectly waterproof, thus avoiding deterioration of the insulation and the accumulation of water which cause serious roof overloading problems.
