Described herein is an stain and sag resistant acoustic building panel comprising a porous body formed from building material and latex binder, wherein the building material may include fibers and filler and at one of the building materials has been pre-treated with a charge-modifying component, thereby enhancing the sag-resistance of the building panel.

The present disclosure provides insulated panels comprising a core layer including an insulating material, an interior-side sheathing layer, and an exterior-side sheathing layer. The insulated panels of the present disclosure can be used to conveniently retrofit existing structures to dramatically improve thermal insulation performance without substantially increasing a risk of moisture retention or mold formation within the structure's walls.

A precast concrete wall structure and method for forming a wall structure are disclosed. A forming member is positioned within a casting bed. The forming member comprises a layer of insulating material defining a plurality of integrally-formed rectangular protrusions extending in a parallel and spaced-apart relationship to one another to define a plurality of rectangular-shaped channels therebetween. The forming member also defines at least one cutout for defining a first portion of a fastener for securing the wall structure to a support structure. A second portion of the fastening member is positioned within the cutout. Uncured concrete is placed within the casting bed and allowed to cure.

The insulating barrier of a panel including has a first stratum and a second stratum, each having a plurality of ridges that face each other, and run athwart of each other. Clearance between at least some adjacent pairs of the ridges provide a mechanical chase that reaches across at least most of the panel. A cladding overlaying at least one side of the insulating barrier is denser than the barrier. The mechanical chase is in the form of a groove through which a utility feed can be routed when the panel is to be mounted in a building.

A panel comprised of at least one connector that facilitates connection with an adjacent panel. An exemplary embodiment of a panel may be comprised of a female connector and a male connector such that the male connector may be inserted in a female connector of an adjacent, substantially similar panel. The female connector may include a ridge, and the male connector may include a flange. An exemplary embodiment of a panel assembly may be formed when a male connector of one panel is inserted in a female connector of another panel such that the flange of the male connector slides over the ridge of the female connector to interlock the panels.

Example systems and methods of constructing multi-storey buildings utilizing a plurality of prefabricated insulated panels, each prefabricated insulated panel comprising a first cementitious layer, a second cementitious layer, and an insulative core, wherein the insulative core is disposed between first and second cementitious layers. The systems and methods comprise constructing a building foundation and constructing a plurality of storeys on said foundation. Each storey may comprise a plurality of prefabricated insulated panels forming a load-bearing exterior wall disposed on an outer perimeter of the storey. Each storey may comprise a plurality of prefabricated insulated panels forming core walls, wherein the first and second cementitious layers of the core wall panels comprise a fire resistant material. Each storey may comprise a plurality of prefabricated insulated panels forming demising walls. Each storey may comprise a plurality of prefabricated insulated panels forming corridor walls. Each storey may comprise a plurality of prefabricated insulated panels forming a floor. The systems and methods further comprise constructing a roof on top of the last storey thereby constructed, the roof comprising a plurality of prefabricated roof panels.

The Invention is a panel of modular pieces that can be assembled into a series of different useful objects that include a chair, table, wall, car chassis and a series of additional items that efficiently accomplish desired outcomes without the need for tools, nails or significant additional pieces. One side of the panel is fully flat to allow for smooth outward facing surfaces on constructions, while the other side has holes that can be used to affix knobs, secure the panels to each other to secure them in a manner that accomplishes a useful purpose with modular poles, snaps, hinges and bearings.

A system for installing prefabricated wall panels in a building includes a lower sill plate adapted to be fastened to a foundation, an upper sill plate fastened to a bottom of the prefabricated wall panel and adapted to be inserted within the lower sill plate, and a plurality of openings in the upper sill plate. The openings are adapted to allow grout to be inserted between the upper sill plate and the lower sill plate after the upper sill plate is inserted within the lower sill plate.

A structural insulated sheathing including a rigid foam insulation board having a first face, a structural member having a second face, wherein the first face of the foam insulation board is laminated to the second face of the structural member over substantially 100% of the interface between the first face and the second face.

A pre-engineered metal building configured to reduce air leakage through the shell of the building by providing an insulation system for fully sealing an enclosed space within the structural frame of the building. The insulation system includes a vapor barrier that defines the enclosed space, at least one insulation layer, and a continuous air barrier. Roof sheeting and side wall facing are attachable to the structural frame to form a shell about the building, and at least a portion of the insulation system is positioned between the shell and the structural frame.
