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 pre-fabricated construction panel for use on an external surface and/or as part of a budding or construction is provided. The panel comprises at least a first layer which is at least partially provided from thermally insulating material having a first surface, the panel comprising at least a second layer, the at least second layer being provided from fiber cement board, the second layer having a second surface facing the first surface. The first surface is profiled having recessed surface zones and heightened surface zones, the first and second layers being connected one to the other at least along the heightened surface zones of the first, the recessed surface zones provides at least one interspace between the first and second surface. This at least one inter-space has at least two openings to the external of the panel for enabling air to flow into and out of the interspace towards the external of the panel. Less than 25% of the total surface of the first surface is connected to, e.g. adheres to, the second surface.

Described herein is a wall assembly for use in walls of energy efficient residential or commercial buildings which can provide improved thermal resistance, moisture resistance and structural capacity. The wall assembly includes a frame assembly; a sheathing layer; a closed cell inner foam layer for coupling the layer to the frame assembly; and an outer fiberboard. Also described herein is a method of manufacturing the wall assembly.

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 structural insulated panel is provided. The structural insulated panel comprises a substantially flat PET foam core having a predetermined length, width, and thickness. At least a fiberglass layer is disposed on each of a first and a second surface of the PET foam core. At least a groove is disposed in the PET foam core. The at least a groove is disposed in proximity to an edge of the PET foam core and is adapted for accommodating a joining element therein.

An acoustic isolation booth for providing a space for noisemaking out of earshot from other parties. wherein: the acoustic isolation booth comprises a shell comprising at least two compartments, an intermediate wall, a plurality of outer walls, a ceiling and one or more entryways. The shell comprises a shell width, a shell depth and a shell height. The two compartments comprise at least a first compartment and a second compartment. each of the two compartments comprises a compartment depth, a compartment width and a compartment height. A first side wall, the intermediate wall and a second side wall are configured to divide a space within the shell into the first compartment and the second compartment.

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.

The invention relates to a method for foaming chipboard with tubes including a board body interspersed by tubes and having an upper and a lower face includes the steps of providing a corresponding chipboard with tubes, defining one or more machining regions on the upper and/or lower face of the chipboard with tubes, machining the machining regions.

In order to provide a method for foaming chipboard with tubes and a chipboard with tubes having foamed tubes that can be used in a simple, flexible, and cost-effective manner while also being highly robust, a foam-forming material is introduced at least in portions of at least one of the above-mentioned tubes in the machining region in order to locally reduce the difference in density between the tubes and the board body. The invention further relates to the use of a device for foaming tubes of a chipboard with tubes.

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 non-wicking underlayment board and methods for forming the same. The non-wicking underlayment board includes a foam core formed of closed cell foam with reinforcement layers encapsulated within the foam core. Outer facings formed of mineral coated nonwoven fibers are positioned on opposite faces of the non-wicking underlayment panel. The non-wicking underlayment board is useful for efficient and cost effective installation of barriers and surfaces in water-resistant and waterproof environments.
