Title (EN) ROOF COVERING
(FR) COUVERTURE DE TOIT
Abstract: front page image
(EN)The covering, intended to cover with green an inclined roof, comprises an imputrescible support, to be laid on the roof without shearing efforts. This support is provided on its upper face with shoulders (12, 14, 16) for holding a vegetable layer(s) and a shear derivation means (10) connecting, in order to resist traction and shearing, the shoulders to the ridge and/or to the roof drain. Preferably, the shoulders form a very porous tridimensional structure, receiving the layer(s) comprised of inter woven irregularly artificial filaments. These filaments are fixed to a shear-resistant filtering mat, optionally capable of storing humidity, acting as a shearing derivation means (10). A very porous lower draining (18, 22, 24), may be made as the upper tridimensional structure and fixed to the lower face of the mat. This covering may be laid on a roof by unrolling it from a roller.
(FR)La couverture, destinee a couvrir de vert un toit incline, comporte un support imputrescible, a poser sur le toit sans sollicitations de cisaillement. Ce support presente, sur sa face superieure, des epaulements (12, 14, 16) pour le maintien, en empechant son glissement, d'une couche vegetale(s) et un moyen de derivation de cisaillement (10) reliant, de maniere a resister a la traction et au cisaillement, les epaulements au faite et/ou a l'egout du toit. De preference, les epaulements forment une structure tridimensionnelle, tres poreuse, accueillant la couche(s) constituee de filaments artificiels entrelaces de maniere irreguliere. Ces filaments sont fixes sur une natte filtrante resistante au cisaillement pouvant eventuellement emmagasiner l'humidite, servant de moyen de derivation de cisaillement (10). Un drainage (18, 22, 24) inferieur tres poreux, peut etre realise comme la structure tridimensionnelle superieure et fixe sur la face inferieure de la natte. Cette couverture peut etre posee sur un toit en la deroulant d'un rouleau.
