A material for use in building construction (partition, wall, ceiling, floor or door) that exhibits improved acoustical sound proofing and fracture characteristics optimized for efficient installation. The material comprises a laminated structure having as an integral part thereof one or more layers of viscoelastic material which also functions both as a glue and as an energy dissipating layer; and one or more constraining layers, such as gypsum or cement-based panel products modified for easy fracture. In one embodiment, standard paper-faced wallboard, typically gypsum, comprises the external surfaces of the laminated structure with the inner surface of said wallboard being bare with no paper or other material being placed thereon. The resulting structure improves the attenuation of sound transmitted through the structure while also allowing installation of the sound proofing material as efficiently as the installation of standard material when the sound proofing material is used alone or incorporated into a partition assembly.

A soundproofing structure comprises a jacket having an external surface and an opposite internal surface defining an inner compartment. A resilient and deformable soundproofing material is contained within the Inner compartment and engages the internal surface. Constricting elements are mounted to the jacket for constriction of the jacket to provide inner surface pressure against the soundproofing material for compression thereof. The constricting elements are releasable for selectively releasing inner surface pressure against the soundproofing material for expansion thereof against the inner surface. The soundproofing structure defines a size that is selectively modifiable by selective releasing of the contacting elements.

A storage system is described where goods are stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of tracks on which load handling devices run. The load handling devices take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked out. Each container may be provided with connectors having a push fit male connector located at a top edge of the container and a female connector at a bottom edge of the container. Adjacent containers in a stack can be linked by routing means, which form moldings on each container. The connectors can also have spring-loaded contacts. The provision of these services within individual containers rather than across the system as a whole, allows for flexibility in storage whilst reducing cost and inefficiency.

An enhanced acoustic cell for use in acoustic panels is provided. The provided enhanced acoustic cell has a parabolic-shaped cell floor and a receiving object suspended at its focal point. Components of the enhanced acoustic cell may be easily replicated and installed into a face sheet comprising an array of a plurality of interconnected acoustic cells. The provided acoustic cell, and arrays thereof, may be produced using an additive manufacturing (AM) technology.

A prefabricated demising wall assembly comprising two substrate panels each with an interior and exterior surface, the substrate panels configured to span between a floor and a ceiling of a building unit; a plurality of metal studs connecting the interior surfaces of the two substrate panels, wherein the plurality of metal studs define a space between the substrate panels; a fire sprinkler pipeline between the two substrate panels, wherein at least some of the plurality of metal studs have an aperture accommodating the fire sprinkler pipeline through an interior of the demising wall assembly; and a plurality of hanger elements operably attached to the exterior surfaces of the two substrate panels, wherein the plurality of hanger elements are configured to connect to a plurality of removable finish panels.

Disclosed herein are plaster boards that include first and second layers of hardened plaster material, a liner attached to the first layer of hardened plaster material, and a first material (e.g., a polymer material such as a viscoelastic polymer) adhered between the liner and the second layer of hardened plaster material. The liner includes one or more structurally weakened regions each extending substantially from a first edge to a second opposing edge of the plaster board. The structurally weakened regions of the liner may facilitate creation of a fissure that propagates substantially within a plane within the plaster board. Methods for making the plaster boards may involve drying wet plaster material while it is in contact with a liner having structurally weakened regions, processing a liner to form its structurally weakened regions while in contact with wet plaster material, or processing a liner to form its structurally weakened regions while in contact with hardened plaster material.

A storage system is described where goods are stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of tracks on which load handling devices run. The load handling devices take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked out. The framework may be provided with one or more of the following services: power, power control, heating, lighting, cooling, sensing, and data logging. A method of partitioning the storage system prevents the spread of fire or prevent damage caused by sprinkler activation.
