Composite panels and methods of use and manufacturing are described herein. The composite panels may comprise a foam composite and one or more layers of a facing material. The foam composite may have a density less than or equal to 20 pcf, and the layer(s) of facing material, e.g., inorganic facing material, may have a thickness of 1/16 inch to 1 inch covering at least the front surface of the foam composite.

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.

Fire-retardant panels that include: a frame with multiple holes that reduce heat conduction through the panel; or a frame that includes two portions separated by a layer of fire-resistant material (e.g., gypsum, calcium silicate, or gypsum board). Some embodiments include skins (e.g., sheet metal) or insulation (e.g., between skin and fire-resistant material, for instance, within the frame). In particular embodiments, the fire-resistant material is (e.g., midway) between: two skins, two layers of insulation, two portions of the frame, or a combination thereof. The portions of the frame can be: sheet metal, attached (e.g., screwed) to the skin(s) or to each other, or extend around the perimeter. The frame can include: various elongated members, (e.g., parallel) bends, or holes that are: in at least one row, elongated, or slots (e.g., parallel to each other or to the skin).

A heat insulation and preservation composite board includes a first panel layer and a heat insulation and preservation layer. The heat insulation and preservation layer and the first panel layer are integrally formed. The first panel layer is a fiber-reinforced resin-based composite sheet, a metal plate, a cement plate, a calcium silicate plate, or a gypsum plate. The heat insulation and preservation layer is a fiber-reinforced aerogel felt. A preparation method of the heat insulation and preservation composite board includes: (1) laying the fiber-reinforced aerogel felt flat; (2) laying the first panel layer flat on the upper surface of the fiber-reinforced aerogel felt; (3) performing a hot-press molding process to obtain the heat insulation and preservation composite board.

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.

Disclosed herein are plaster boards having a first surface and an opposing second surface, and a first edge and an opposing second edge that bound the first surface and the second surface. The first surface includes a first section and a second section, the first section being raised compared to the second section, the second section abutting the second edge. The second surface includes a first section and a second section that are separated by a boundary between the first edge and the second edge. The first section of the second surface is substantially parallel to the first section of the first surface. The second section of the second surface slopes toward the first surface from the boundary toward the second edge. Methods for making the plaster boards involve forming wet plaster material and drying the wet plaster material such that the wet plaster material hardens into a plasterboard.

Low combustibility thermal insulation and methods of use and preparation thereof are described herein. The low combustibility thermal insulation may include a foam composite comprising a polymer material and a fire retardant component disposed in and/or adjacent to the polymer material; and a first controlled combustion layer adjacent to a first surface of the foam composite, wherein the foam composite and first controlled combustion layer are configured to control combustion of the insulation such that a total heat generated in a period of 10 minutes by the panel is equal to or less than 8 MJ/m.sup.2, as measured according to ISO 5660-1, and wherein a thermal conductivity of the insulation is equal to or less than 0.050 W/m K.

Various cement-containing compositions are disclosed, including insulating cement, forms, and prefabricated building materials produced from cement-containing compositions with insulating properties. Some of the preferred embodiments include expanded polystyrene and an acrylic component to provide enhanced insulating properties, or have a lower density, lighter weight, and increased insulating R-value in comparison with other cement-containing compositions.

A method of setting tile includes constructing a floor panel and a plurality of wall panels and attaching each of the plurality of wall panels to either the floor panel or one of the other wall panels with a waterproof caulk. Each of the wall panels includes a first rigid layer, a second rigid layer attached to the first rigid layer by a thinset mortar, and a waterproofing layer formed of a flexible material and attached to the second rigid layer by the thinset mortar.

A composite laminate system for indoor and outdoor applications, comprising a wood layer comprised of a thin plank or veneer. An aqueous, penetrating primer is applied in a first coating to all surfaces of the wood layer, and the primer is designed to prevent and resist decay from bio attack, insects and other intrinsic bacteria, featuring antibacterial and mold inhibiting properties, including a UV inhibitor. A first aqueous nano urethane acrylic coating is applied on all surfaces of the wood layer on top of the primer coating. At least a second aqueous nano urethane acrylic coating is applied to a top surface of the wood layer on top of the first aqueous nano urethane acrylic coating. A polyvinyl chloride (PVC) foam sheeting layer is glued to the wood layer with coatings using a resin adhesive glue layer interposed between the PVC foam sheeting and the wood layer.
