A method of producing an arrestor bed for slowing an aircraft overrunning a runway, including paving an area immediately beyond the end of a runway with foamed glass aggregate to define a bed, and covering the bed with a layer of cementitious material to define a composite bed.

A ceiling system includes a ceiling support structure supporting a plurality of ceiling panels, each ceiling panel including a core layer having a top surface facing a first interior space above the ceiling panels, a bottom surface facing a second interior space below the ceiling panels, and a plurality of peripheral edges extending between the top and bottom surfaces. A top frame layer extends from the top surface and a thermal layer is on the top frame layer opposite the top surface. The thermal layer has a first surface facing away from the top frame layer and a second surface facing toward the top frame layer. The top frame layer supports the second surface in a spaced-apart manner from the top surface to form one or more air gaps between the top surface and the second surface. The first and second surfaces have a thermal emissivity of 0.5 or less.

The present disclosure relates to a set comprising a supporting structure, first and second panels and a fastening device for securing the first and second panels to the supporting structure. The fastening device comprises a top portion, having top and bottom surfaces, first and second edge portions, and first and second legs protruding downwardly from the bottom surface. The first and second panels respectively comprise opposite first and second edge grooves into which the first and second edge portions are configured to be respectively inserted. The first and second legs are flexible and bendable towards each other, and respectively comprise first and second locking elements. An upper surface of the supporting structure comprises an insertion groove comprising a first undercut groove and an opposite second undercut groove. The first and second locking elements are respectively configured to be snapped into the first and second undercut grooves to a locked position.

A locking dynamic high NRC acoustic baffle and/or tile and a locking dynamic high NRC ceiling and/or wall system, that includes a single piece of material folded into locking dynamic high NRC acoustic baffles and/or tiles, using locking pieces and locking mechanisms, to quickly and easily install the locking dynamic high NRC acoustic baffle and/or tile onto construction ceiling hangers or onto walls to provide an aesthetically pleasing image, along with a reduction in unwanted noise or room acoustics.

The invention relates to a panel, such as a floor panel, a wall panel or a ceiling panel, in particular a decorative panel and to a method for producing such panel. The panel according to the present invention comprises a core layer comprising a first composite material and a second composite material which have different material characteristics. The panel is further provided with a plurality of cavities.

An acoustic tile made from a single piece of material folded along a plurality of folding scores to form a three-dimensional configuration. The three-dimensional configuration includes a plurality of folded extensions, a plurality of outer surfaces arranged to collectively form a faceted dome, a plurality of inner surfaces comprising a plurality of recesses. The acoustic tile also includes a plurality of locking pieces which engage the plurality of recesses to hold the single piece of material in the three-dimensional configuration.
