Title (EN) ROOFING MEMBRANE AND METHOD
(FR) MEMBRANE DE TOITURE ET METHODE DE FABRICATION
Abstract:
(EN) A bituminous roofing membrane (10), and method of manufacture, is disclosed having a reinforcing mat (16) sandwiched between top (12) and bottom (14) layers of a tacky polymer modified bitumen. The leading edge portion (20) of the top layer (12) is provided with a layer of roofing granules (24). A track of adhesive (26) is provided on the roofing granules (24). The trailing edge portion (22) of the top layer (12) is provided with a layer of non-slip plastic film (28). A release sheet (18) is applied to the bottom layer (14) of the membrane (10) to prevent engagement of the top (12) and bottom (14) layers with one another when the membrane is rolled for storage or shipment. In use, upon removal of the release sheet (18), the membrane (10) is secured to the roof with the leading edge portion (20) constituting a starter strip for receiving thereon the first row of roofing shingles (42), and the trailing edge portion (22) constituting an underlayment for receiving thereon successive rows of roofing shingles (42).
(FR) On décrit une membrane bitumeuse de toiture (10), et sa méthode de fabrication. Cette membrane possède une trame de renfort (16) intercalée entre les couches supérieure (12) et inférieure (14) d'un bitume adhérant modifié par polymérisation. La partie antérieure de toiture (20) de la couche supérieure possède une couche de granulés de toiture (24). Une piste d'adhésif (26) est placée sur les granulés de toiture (24). La partie arrière (22) de la couche supérieure (12) possède une couche de plastique anti-dérapant (28). Une partie détachable (18) est appliquée à la couche inférieure (14) de la membrane (10) de manière à empêcher le contact entre les couche supérieure (12) et inférieure (14) lorsque la membrane est enroulée pour le stockage ou le transport. Lors de l'utilisation après retrait de la partie détachable (18), la membrane (10) est fixée au toit par la partie antérieure (20) constituant une bande de départ permettant de recevoir la première rangée de tuiles (42), la partie arrière (22) constituant une base permettant de recevoir les ranges successives de tuiles (42).
