Sealing sheet assembly for construction surfaces and methods of making and applying same

A sealing sheet (10) assembly bondable to a construction surface comprising (a) an upper layer (14) of a first substance, the upper layer being selected fluid impermeable; and (b) a lower flexible layer (16) of a second substance, the lower flexible layer being bondable to the construction surface. The upper layer and the lower flexible layer are at least partially attached to one another, wherein a combination of the upper layer, the lower layer and the attachment or the partial attachment of the layers to one another are selected such that tensile forces resulting from constructional movements acting upon the sealing sheet result in a local detachment or relative displacement of the upper layer and the lower flexible layer, thereby the ability of the lower flexible layer of transmitting the forces onto the upper layer is remarkably reduced, resulting in improved service of the sealing cover as a whole. The attachment is selected such that a spread of a leakage between the layers via a tear formed in the upper layer is locally restricted.

Roofing materials having engineered coatings

An asphalt-based roofing material includes a coating having a top portion containing a mixture of asphalt and igneous and / or metamorphic rock particles, while the mat portion of the coating contains a mixture of asphalt and a filler which contains less than 10% igneous and / or metamorphic rock particles. In other embodiments, the top portion but not the bottom portion of the coating meets or exceeds a pliability standard, passes a weathering performance test, or has a high solar reflectance. In another embodiment relating to a laminated roofing material, the top portion but not the bottom portion has viscoelastic properties effective to prevent the coating from sticking to an adjacent shingle in a bundle. The invention also relates to a continuous process of applying first and second coatings to a mat for manufacturing a roofing material. In a first coating operation, a first asphalt-based coating is continuously applied to a first surface of the mat so that the first coating saturates the mat and forms a layer on the first surface. In a second coating operation, a second asphalt-based coating is continuously applied to a second surface of the mat so that the second coating forms a layer on the second surface. The second coating has different properties from the first coating.

Cap sheet, roofing installation, and method

A cap sheet for cold-applied adhesive roof installations includes a reinforcement mat saturated with and encapsulated within SBS modified bitumen. Bitumen layers above and beneath the mat have top and bottom major surfaces. The top surface of the top bituminous layer has a first edge portion extending inward from and along a first lateral edge. The bottom surface of the bottom bituminous layer has a second edge portion extending inward from and along a second lateral edge. The bitumen in the edge portions is a pressure-sensitive adhesive that is covered by release liners for protection prior to installation. When the cap sheets are installed, the release liners are removed from the edge portions and overlapping edge portions of the cap sheets are pressed and adhesively bonded together to immediately form effective watertight, weather-secure seams.
