Beschreibung
Zusammenfassung:	As described herein, the invention includes a building underlayment sheet that comprises an underlayment lamina having a top surface and a bottom surface. The bottom surface includes an interior portion and a selvage portion that extends from the interior portion of the bottom surface to a terminal distal edge of the sheet and the interior portion of the bottom surface bears a self adhesive layer. The selvage portion of the bottom surface bears a bonding composition that is capable of bonding to a top surface of a second underlayment lamina to form a full lap joint In some embodiments, the self adhesive layer includes an asphalt, a polymer such as poly(styrene- butadiene-styrene)( SBS), and a tackifier, and/or the bonding composition includes asphalt, a polymer such as poly(styrene-butadiene- styrene ), ground tire rubber (GTR), and tackifier. La présente invention concerne une feuille servant de sous-couche de construction qui comprend une lamelle servant de sous-couche ayant une surface supérieure et une surface inférieure. La surface inférieure comprend une partie intérieure et une partie lisière qui s'étend de la partie intérieure de la surface inférieure jusqu'à un bord distal terminal de la feuille et la partie intérieure de la surface inférieure porte une couche auto-adhésive. La partie lisière de la surface inférieure porte une composition de liaison qui peut se lier à une surface supérieure d'une seconde lamelle servant de sous-couche pour former un joint à recouvrement complet. Dans certains modes de réalisation, la couche auto-adhésive comprend un asphalte, un polymère tel que le poly(styrène-butadiène-styrène) (SBS) et un agent donnant du collant, et/ou ladite composition de liaison comprend de l'asphalte, un polymère tel que le poly(styrène-butadiène-styrène), du caoutchouc de pneumatique broyé (GTR), et un agent donnant du collant.
