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.

The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a porous facing and to methods for making such panels. One aspect of the disclosure is an acoustic panel comprising a base structure. The base structure has one or more edges, an outward major surface having a total area, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The panel includes a coating layer directly disposed on the outward major surface of the base structure, the coating layer being formed of an open-cell foam. The coating layer has an exterior major surface opposing the outward major surface of the base structure. The coating layer is substantially scattering for light in the wavelength range of 380 nm to 780 nm, and has an absorption coefficient of less than 0.5 for acoustic frequencies in the range of 100 Hz to 10,000 Hz.

A barrier and method of manufacture thereof is provided. The barrier is suitable for enhancing the reaction to fire of structural elements such as construction boards.

A floor panel includes at least two reinforcing layers extending in a direction parallel to a plane defined by the panel to allow one of the at least two reinforcing layers to be situated at a level between 30˜70 percent of a thickness from a top surface of the panel to a highest part of a top surface of the tongue, and/or a bottom surface of the panel to a lowest part of an upper surface of the lower lip.

Described herein are details for designing and manufacturing enhanced shock and impact resistant helicoidal lay-ups by combining nanomaterials, variable pitch and partial spirals, Thin unidirectional fiber plies, hybrid materials, and/or curved fibers within a ply. The helicoidal structures created in the prescribed manners can be tuned and pitched to desired wavelengths to dampen propagating shock waves initiated by ballistics, strike forces or foreign material impacts and can arrest the propagation of fractures including catastrophic fractures. These enhancements open the helicoidal technology up for use in such applications as consumer products, protective armor, sporting equipment, crash protection devices, wind turbine blades, cryogenic tanks, pressure vessels, battery casings, automotive/aerospace components, construction materials, and other composite products.

Panels for coupling stone or brick units to a wall structure are disclosed herein. The panels can include an expanded polystyrene foam having a plurality of laterally extending channels formed on one or more of a first and second side of the panel. The channels can aid in adhering a plurality of stone or brick units to the panel. The width of the channels can be less than the width of the stone or brick units such that the stone or brick units are disposed outside the channels when coupled to the panel.

A composite foam article is disclosed herein. The composite foam article comprises a polyurethane foam core presenting a first surface and a second surface facing opposite the first surface. A first skin is disposed on the first surface and a second skin is disposed on the second surface. The first and second skins comprise a plurality of fibers and a polymeric binder. The composite foam article also comprises at least one supplemental layer comprising an ethylene and acrylic acid copolymer dispersed in and/or disposed between any of said aforementioned skins and core.
