A modular flooring system for performance weightlifting and similar activities is provided. The modular flooring system is constructed from one or more individual flooring modules that are interlocked and connected together to provide a customized flooring surface platform. The modular flooring system can include a lifting platform module having a hardwood top surface layer and a subfloor construction. The modular flooring system can include a drop-zone platform module having a rubberized top surface layer and a subfloor construction designed to absorb and withstand the force impact of dropped weights onto the top surface layer. The subfloor construction of the drop-zone module can include an upper subfloor layer, an intermediate subfloor layer and a lower subfloor layer. The intermediate and lower subfloor layers can each including alternating panel sections with one panel section constructed from a foam-based material.

Building materials such as structural panels, beams, roof decking, and flooring panels, are packaged within a protective layer including a sublayer of a polymeric material that can be applied at the factory. The protective layer protects the underlying building materials from exposure to weather and potential damage due to handling during shipping, at a job site, and which can be left in place during construction, thus eliminating the need for temporary protective measures covering the building materials. The protective layer may have additional properties such as breathability, fire resistance, and sound absorption. The protective layer also may provide an underlayment such as for flooring and roofing.

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 vehicle interior member includes: a first core material; a first skin forming a first rim part in which at least a part of the peripheral edge part is folded back to the back surface side of the first core material to sandwich a peripheral edge part of the first core material; a second core material; a second skin forming a second rim part in which at least a part of the peripheral edge part is folded back to the back surface side of the second core material to sandwich a peripheral edge part of the second core material; and a stitch part that stitches the first rim part, the peripheral edge part of the first core material sandwiched by the first rim part, the second rim part, and the peripheral edge part of the second core material sandwiched by the second rim part.

A process for producing rigid PUR/PIR foams comprising A1 an isocyanate-reactive component, A2 a flame retardant, A3 a blowing agent, A4 a catalyst, A5 optionally auxiliaries and additives, and B an organic polyisocyanate component. Component A1 comprises a triurethane triol A1.1 and a compound A1.2 selected from the group consisting of polyether polyol, polyester polyol, polyether carbonate polyol, and polyether ester polyol. Also disclosed is a rigid PUR/PIR foam, an insulating material, a composite element, and a mixture.

A flexible article is provided having a core formed from a plurality of laminar panels that are inter-connected to provide an expandable structure upon movement of the panels away from each other. Opposite ends of the core terminate in a pair of end panels whereby the end panels may be moved apart to expand the expandable structure. Each of the panels are made from wood material. The panels, for example, include two wood sheets with longitudinally oriented grains and a flexible backing sheet that is sandwiched and adhered between the two wood sheets.

An integrated roofing product comprising a wood or cellulosic structural or roof sheathing base or core panel with a rigid foam insulation sheet or layer laminated or otherwise attached to the panel's inner face. Shingles and/or other protective material may then be attached to the panel's outer face. A plurality of parallel air channels extend vertically in the rigid foam insulation sheet or layer, providing a pathway for air to pass up and out of the eave space. Some or all of the air channels are disposed on the surface of the foam layer that is laminated or attached to the panel's inner face, so that part of the air channel is formed at the interface. A radiant barrier layer may be placed on the inner face of the rigid foam insulation sheet or layer, or between the foam insulation and the inner face of the roof sheathing base or core panel.

A process for fabricating a unitized structure comprises creating a multilayer structure by applying a flame-retardant resin to a first layer and stacking, on the first layer, an intermediate layer comprising a honeycomb structure. Further, a second layer is stacked on the intermediate layer and the flame-retardant resin is applied to the second layer. The multilayer structure is then heated to a desired temperature and a pressure is applied about the multilayer structure for a predetermined process time. Moreover, the flame-retardant resin is prevented from entering spaces of the honeycomb structure. After elapse of the predetermined process time, the pressure is released, creating the unitized structure.

The present invention relates to a thermally crosslinkable composition comprising an acid-modified polymer A having a melting point of 110 to 150° C. and a crystallization temperature of 50 to 90° C., an acid-modified polymer B having a melting point of 30 to 110° C. and a crystallization temperature of lower than 50° C., a tackifier resin, and a curing agent, wherein the thermally crosslinkable composition has a crystallization temperature of 30 to 70° C.

An enclosure member for a building structure comprising a planar laminate having a first facing layer; a layer of foam having a first face and a second opposing face; and a second facing layer; where the first facing layer is fastened to the first face of the layer of foam, and the second facing layer is fastened to the second opposing face of the layer of foam. An edge of the enclosure is provided with a perimeter structure that can perform one or more of a sealing function, an edge reinforcement function and a pivotable joining function with another enclosure, in accordance with the particular embodiment.
