Some embodiments of the present disclosure relate to a roofing system. In some embodiments, the roofing system includes a roofing membrane, which may include a cap, a scrim, and a core. In some embodiments, the roofing system may also include an adhesive film, which may include a first adhesive layer adhered to the roofing membrane, a second adhesive layer configured to adhere the roofing membrane to a roofing substrate, and a barrier layer positioned between the first and second adhesive layers. Methods of manufacturing roofing systems are also disclosed.

A manufactured building system is described. The building system can include modular components such as floor panels, roof panels, window walls, demising walls, utility walls, end walls, and/or corbel beams.

The present invention is directed to an improved gypsum board, such as an improved sound damping gypsum board, and a method of making such gypsum board. For instance, the method comprises: providing a first encasing layer and a first sound damping layer on the first encasing layer wherein the sound damping layer includes at least 50 wt. % of a first sound damping polymer; depositing a gypsum slurry comprising stucco and water on the sound damping layer to form a gypsum core; providing a second encasing layer on the gypsum slurry; and allowing the stucco to convert to calcium sulfate dihydrate.

The invention is a system and method for building a polar zonohedron structure from precast cement panels. The building system may include a plurality of panels configured to register with each other. Each panel includes a precast cement base with side walls enclosing a cavity within the precast cement base. The panels include at least one ridge protruding from at least one surface of a side wall of the panel and at least one aperture on at least one surface of a side wall of the panel. Each ridge is preferable configured to interlock with each aperture; in his way, the panels interlock with each other to form the polar zonohedron structure.

A method for waterproofing a substrate includes steps of: attaching a separation sheet to the surface of the substrate; and attaching a waterproofing membrane sheet to a surface of the separation sheet by a plurality of adhesive elements having a first and second major adhesive surface, wherein the separation sheet is a non-woven fabric sheet, or an embossed polyolefin membrane sheet and each adhesive element includes an adhesive layer composed of a pressure sensitive adhesive.

A ceiling panel having a connection portion at one of end portions on both sides in a first direction of a panel body in a shape of a rectangular flat plate, the connection portion connecting with a connected portion of an adjacent ceiling panel. The connection portion is fixed to the end portion by a fastener, the fastener being fastened to an insertion part inserted into a layer of the panel body from a cut portion opening on a back face of the end portion so as to penetrate a securing part provided along the back face of the end portion.

A multilayer thermoplastic sheet, comprising a first colored thermoplastic layer; a second colored thermoplastic layer; and a third colored thermoplastic layer; wherein at least one of the colored layers is a different color than at least one of the other two colored layers; and a multilayer thermoplastic sheet, wherein the sheet has a total thickness of from about 0.125 inches to about 0.500 inches, and a plurality of lines cut into the surface at depth of from about 0.010 inches to about 0.080 inches. Lines may be cut into a multilayer thermoplastic sheet via computer numerical control (CNC) routing to simulate ceramic tile.

A panel and a method of making a panel are provided. The panel comprises a cured polymeric foam layer that is formed by application of a foam composition to an edge surface of the panel and then shaped and cured. The panel comprises man-made vitreous fibre or wood wool cement.
