An object is to provide a soundproofing structure which exhibits high soundproofing performance in a broad frequency band, can be miniaturized, can ensure ventilation properties, and has a light transmittance, and a cylindrical structure, a window member, and a partition member including this soundproofing structure. Provided is a soundproofing structure including: a soundproofing cell which includes a frame having a frame hole portion passing therethrough and a film that covers the frame hole portion and is fixed to the frame, in which the film has a plurality of through-holes passing therethrough in a thickness direction, an average opening diameter of the through-holes is in a range of 0.1 m to 250 m, and a vertical direction of a film surface is disposed so as to be inclined with respect to a direction of a sound source to be soundproofed.

A containment system for separating a containment area from an external environment may include one or more panel assemblies, various types of door assemblies, a flexible corner assembly, and other components that form a modular system capable of adapting to various configurations using a minimal number of fasteners, brackets, and/or clamps.

The invention relates to a drywall comprising a first wall section (2) with first stud elements (4), wherein the first stud elements are arranged with a first regular centre distance, wherein in the first wall section a first panelling (5) is arranged at least on one room side (R) of the first stud elements (4). The drywall is characterized by a second wall section (3) with second stud elements (6), wherein a second panelling (7) is arranged in the second wall section at least on the room side (R) of the second stud elements (6) and wherein the second stud elements are arranged with a second regular centre distance (C) which is smaller than the first regular centre distance (A). The invention also relates to a kit and a method for constructing a drywall.

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 containers comprise liners formed from flame retardant or flame suppressant material. Containers comprising liner means are used to store ignitable items within the storage system.

A modular thermal transfer emitter configured to be compatible with installation for indoor radiative heating and cooling. For example, modular emitters radiatively and conductively heat and/or cool an interior space in a building using a heat exchanger and tubing through which thermal fluid flows. These modular emitters can be arranged within a suspended ceiling, walls, flooring of a residential and commercial building. A system for exchanging heat from components can include multiple heat exchangers adjacent to the components and one or more pumps connected to the heat exchangers. The pumps can generate water flow that brings the heat to a secondary heat exchanger. Because the modular emitters can have a large area (e.g., spanning a significant percentage of the ceiling or wall) a desired amount of heat transfer can be achieved without requiring a large temperature difference between the thermal fluid and the ambient surroundings.

A sound damping wallboard for installation on an installed wallboard, a sound damping wallboard system, and a method of constructing a sound damping wallboard on a building structure are disclosed. The sound damping wallboard includes a gypsum layer having a gypsum layer inner surface and a gypsum layer outer surface, a first sound damping layer disposed at the gypsum layer inner surface and having a first sound damping layer inner surface opposite the gypsum layer inner surface, a first encasing layer disposed at the gypsum layer outer surface, a second encasing layer disposed at the first sound damping layer inner surface, and a second sound damping layer disposed at the second encasing layer opposite the first sound damping layer inner surface.

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.

Certain example embodiments relate to an acoustic wall assembly that uses active and/or passive sound reverberation to achieve noise-disruptive functionality, and/or a method of making and/or using the same. With the active approach, sound waves in a given frequency range are detected by a sound masking circuit. Responsive to detection of such sound waves, an air pump (e.g., speaker) is used to pump air in the wall assembly to actively mask the detected sound waves via reverberation and/or the like. The wall assembly may include one, two, or more walls, and the walls may be partial or full walls. With the passive approach, sound waves in a given frequency range are disrupted via features (e.g., holes, slits, etc.) formed in and/or on a wall itself. These techniques may be used together or separately, in different example embodiments.

A building system may include at least one diaphragm beam having opposite ends connected to an external structural frame of a building, at least one pre-assembled floor-ceiling panel adjacent to a vertical side of and coupled to the diaphragm beam, and at least one pre-assembled wall adjacent to a horizontal side of and coupled to the diaphragm beam, The diaphragm beam may be filled with a mineral-based material, such as concrete. The one or more pre-assembled floor-ceiling panels may each include a plurality of joists extending perpendicular to the diaphragm beam, a floor-panel including at least one metal layer attached to the joists on a floor side of the pre-assembled floor-ceiling panel, and a ceiling panel including at least one layer comprising mineral-based material attached to the joists on a ceiling side of the pre-assembled floor-ceiling panel. The one or more pre-assembled walls may include interior and/or exterior walls of a building.

A method of assembling a building unit in accordance with a floor plan of a building using prefabricated components may include installing a first prefabricated floor panel in a first position of the building unit, the first floor panel being selected from a first plurality of prefabricated floor panels having a same first width; installing a second prefabricated floor panel in a second position of the building unit, the second floor panel being selected from a second plurality of prefabricated floor panels having a same second width; and installing a third prefabricated floor panel in a third position of the building unit, the third floor panel being selected from a third plurality of prefabricated floor panels. The floor panels in the third plurality of prefabricated floor panels may have different widths. The third floor panel may be selected such that a sum of the widths of the first, second, and third floor panels corresponds to the total width of the building unit in accordance with the floor plan.
