An approved dynamic construction is used for effectively thermally insulating and sealing of a safing slot between a floor of a building and an exterior wall construction. The exterior wall construction includes a curtain wall configuration defined by an interior wall glass surface including one or more aluminum framing members, wherein the vision glass extends to the finished floor level below. The dynamic, thermally insulating and sealing system includes a first element for receiving the insulating elements and positioned in the zero spandrel area of a glass curtain wall construction including only vision glass to maintain thermally insulating and sealing of the sating slot during exposure to fire and heat as well as movement in order to maintain a complete seal extending across the safing slot.

Described is an approved dynamic construction for effectively thermally insulating and sealing of a safing slot between a floor of a building and an exterior wall construction wherein the exterior wall construction comprises a curtain wall configuration defined by an interior wall glass surface including one or more aluminum framing members. In particular, a process for assembling a unitized panel for use within an exterior dynamic curtain wall assembly, which includes glass, especially vision glass extending to the finished floor level below, is described as well as a unitized panel assembled according to said process and its installation to improve fire stopping at the safing slot.

A dynamic acoustic system for use in connection with an indoor environment includes a plurality of elongated acoustic bars and a controller operably to each of the elongated acoustic bars. Each of the bars is operably coupled to a ceiling member of the indoor environment and includes an upper portion, a lower portion, a plurality of side surfaces extending between the upper and lower portions, an interior region at least partially defined by the upper portion, the lower portion, and the plurality of side surfaces, and at least one movable element movable between first and second positions. The controller selectively controls operation of the at least one movable element of a desired number of the plurality of elongated acoustic bars to alter an environmental characteristic of the indoor environment.

An acoustic panel is disclosed. In various embodiments, the acoustic panel includes a first layer; a cell having a first cell end connected to the first layer and a second cell end spaced a cell length from the first cell end, the cell having a first wall extending between the first cell end and the second cell end; and a septum having a central portion positioned within the cell and a first tab extending from the central portion, the first tab defining a first surface positioned against the first wall and a first distal end positioned adjacent the first layer.

Described is an approved dynamic construction for effectively thermally insulating and sealing of a safing slot between a floor of a building and an exterior wall construction wherein the exterior wall construction comprises a curtain wall configuration defined by an interior wall glass surface including one or more aluminum framing members. In particular, a process for assembling a unitized panel for use within an exterior dynamic curtain wall assembly, which includes glass, especially vision glass extending to the finished floor level below, is described as well as a unitized panel assembled according to said process and its installation to improve fire stopping at the safing slot.

An acoustic-absorber system incorporates a plurality of acoustic-baffle assemblies in cooperation with an acoustic cavity. Each acoustic-baffle assembly incorporates a plurality of nested fluted cups, wherein at least one fluted cup of a first type having at least one orifice at at least one radially-inwardly-extending grooved portion is interleaved with at least one fluted cup of a second type having at least one orifice at at least one radially-outwardly-extending ridged portion. Externally-generated soundwaves entering either from the inside of an innermost fluted cup, or from the outside of an outermost fluted cup, travel through the at least one orifice thereof, and along a circuitous path along the gaps between adjacent cups and through at least one orifice of each of other fluted cups from one gap to another, until finally propagating into the acoustic cavity through at least one orifice of the outermost, or innermost, fluted cup for subsequent additional attenuation by destructive interference from phase cancellation within the cavity.
