Methods, systems, and apparatus for constructing a wall panel and building are disclosed. The wall panel can include: fiber-reinforced concrete layers including concrete with interwoven fibrous materials; an insulation layer; and a connector. The insulation layer is sandwiched between the fiber-reinforced concrete layers, and the connector extends through the insulation layer and concrete layers to create composite action between the insulation layer and the concrete layers.

Embodiments of the invention provide roofing boards and roofing systems having improved fire resistance properties and methods related to the same. According to one aspect, a roofing system is provided. The roofing system includes roofing panels positioned atop structural support members to form a roof deck. Roofing boards are positioned atop the roof deck and coupled thereto and a roofing membrane is positioned atop the roofing boards and coupled therewith. The roofing boards include a coating of a mineral based material applied to one or more surfaces in an amount between the range of about 0.10 lbs/ft.sup.2 and about 0.70 lbs/ft.sup.2. The mineral based material coating enables the roofing boards to pass the UL 790 class A tests, such as the burning brand test.

A floor, wall, or ceiling panel has a base made of a wood material and an upper veneer. The base and the veneer are hot-pressed together while incorporating a resin layer. During the pressing process, pores, cracks, and/or gaps in the veneer are filled with resin. In particular, the pressing process is carried out such that the veneer is saturated with resin, and the resin can be seen on the surface of the veneer after the pressing process The adhesion of the veneer to the base and the smoothing of the veneer are thus carried out in one operation.

A floorboard, includes a carrier plate and a veneer arranged on a topside of the carrier plate, wherein the carrier plate and the veneer are connected with each other via a resin, wherein an edge strip made of the resin is provided on at least two side margins of the veneer, and wherein a surface of the edge strip extends in a same plane as a surface of the veneer.

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.

A cementitious composite for in-situ hydration includes a structure layer having a first side and an opposing second side, a cementitious material disposed within the structure layer, a sealing layer disposed along and coupled to the first side of the structure layer, and a containment layer disposed along the opposing second side of the structure layer. The structure layer has an intersection at the sealing layer and the containment layer that is at least partially fiberless. The cementitious material includes a plurality of cementitious particles. The containment layer is configured to prevent the plurality of cementitious particles from migrating out of the structure layer.

A trestle mat construction panel configured for use with building equipment and a method of manufacture and use thereof. The trestle mat construction panel is preferably formed of a partially hollow core body and strong support material to allow the construction panel to be easily placed and moved and to support various materials, such as construction equipment including cranes and the like, when in use.

A wall panel may have a layer made from magnesium oxide, a first insulation layer made from a two-part rigid urethane pour foam, and a second insulation layer made from a phase change material. The first insulation layer maybe chemically bonded to the magnesium oxide layer and may also be bonded to the phase change layer. The first insulation layer may be positioned between the second insulation layer and the magnesium oxide layer. The magnesium oxide layer may be a finished surface or a veneer layer may be applied to the magnesium oxide layer.

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.
