Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.

Structural insulated wall and roof sheathing systems for use in building construction designed to provide a structural building envelope that is moisture permeable but protects from bulk water, excess air, and thermal transfer.

A panel for forming part of a partition is disclosed. The partition may, for example, be a roof, a wall or a floor of a building. The panel comprises: a central panel; two support members; and a resiliently compressible portion. The two support members are disposed on opposed sides of the central panel, each of the two support members extending generally perpendicularly to a plane of the central panel. The resiliently compressible portion is arranged between the two support members such that a distance between the two support members can be reduced by compressing the resiliently compressible portion.

A panel is disclosed for use in construction. The panel comprises opposing surfaces that extend between first and second opposite ends. The panel also comprises a plurality of parallel (e.g. sawtooth) ridges. The ridges are provided on at least one of the opposing surfaces. The ridges extend along and adjacent to a first of the opposite ends of the panel for at least a part length thereof. The ridges are arranged to engage with and move past corresponding ridges of an adjacent panel when the panels move relative to each other in opposite directions. The ridges are further arranged so as to interfere with the ridges of the adjacent panel to resist relative movement in a reverse of the opposite direction.

A twin sheet core structure made up of two sheets of plastic that have been thermoformed to define arrays of cavities having floors opening to surfaces defined by orthogonally intersecting ribs wherein the sheets are fused together to form a single structure with hollow areas between sheets.

Various implementations include a sound barrier panel including first and second polymeric foam portions, a rubber membrane, and a polyurea coating. The first and second polymeric foam portions each have a first surface, a second surface opposite and spaced apart from the first surface, a first end, a second end opposite and spaced apart from the first end, a top end, and a bottom end opposite and spaced apart from the top end. The second surface of the first polymeric foam portion abuts a first surface of the rubber membrane, and a second surface of the rubber membrane abuts the first surface of the second polymeric foam portion. The polyurea coating covers at least the first surface of the first polymeric foam portion and the second surface of the second polymeric foam portion.

A composite material may be used as a building material to provide desirable visible aesthetics, such as in a roof or facade. The composite material may include two or more materials, wherein a first material provides desirable qualities for appearance and a second material provides desirable qualities for strength or other characteristics desirable of a building material. Each of the first material and the second material may be transparent, such that the composite material is also transparent. The first material may be Ethylene tetrafluoroethylene (ETFE) and the second material may be Polyethylene terephthalate (PET).
