The present invention is directed to ceiling panels formed from a porous scrim that is coupled to an acoustical substrate using a scrim attachment system that includes an adhesive.

Systems and methods are disclosed for a multi-layered sound absorption structure. The multi-layered sound absorption structure may include a form material, an acoustic material disposed on a surface of the form material, and a construction material disposed on the acoustic material. The acoustic material may couple to the construction material during curing of the construction material. After the construction material is cured, the form material may be removed exposing a least a portion of the acoustic material.

The present invention is directed to an acoustic ceiling panel having a first major exposed surface opposite a second major exposed surface, the acoustic ceiling panel comprising: a first layer having an upper surface opposite a lower surface, the first layer comprising: a first body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the first body being air-permeable; and a first attenuation coating applied to the first body; a second layer having an upper surface opposite a lower surface, the second layer comprising: a second body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the second body being air-permeable; and a second attenuation coating applied to the second body; and an adhesive present between the first and second layers.

A baffle tile has a tile and a baffle. The tile is sized and shaped to be placed in a drop ceiling grid, and has a slot through its thickness. The body of the baffle is inserted into the slot in the tile so that the baffle hangs down from the tile. A pair of folding flaps are defined in an upper extent of the baffle by respective fold lines. The folding flaps are folded outwardly and down, such that they abut the upper surface of the tile. Folded down, the folding flaps define a locking slot. A locking member with features complementary to the locking slot is inserted into the locking slot to lock the folding flaps into position. The baffle itself may have additional fold lines so that it can be folded into its usable configuration from a flat sheet of material, without adhesives or fasteners.

In one aspect, a folded ceiling baffle is constructed from a sheet of felt. For example, in a particular implementation, the folded ceiling baffle is constructed from a sheet of felt having respective portions of shape and size that may be folded to form the ceiling baffle.

An end cap for a ceiling panel of a ceiling system. The end cap includes a face plate having an inner surface, a bottom edge, a top edge, a first side edge, and a second side edge. A first insertion plate extends from the inner surface of the face plate at the top edge of the face plate. A second insertion plate extends from the inner surface of the face plate at the bottom edge of the face plate. A concealment portion extends from the inner surface of the face plate along the first and second side edges of the face plate. The concealment portion may include an upper section positioned above the first insertion plate and spaced from the first insertion plate by a first gap and a lower section of positioned below the second insertion plate and spaced from the second insertion plate by a second gap.

A modular suspended ceiling assembly is provided having by multiple panels formed by spaced from each other first and second connecting walls, with first and second main brackets connected to the first connecting wall. First and second auxiliary brackets connected to the second connecting wall. A plurality of suspension members with each suspension member being connected to a hollow support structure. A guide passes through the hollow support structure. A module is formed by adjacent panels supported by the single guide passing through the support structure and accompanied by engagement of the main and auxiliary brackets.

A collapsible acoustic honeycomb ceiling installation can be made by cutting desired material into panels. Next, a manufacturer can cut one or more notches into the panels. The manufacturer can assemble the collapsible acoustic honeycomb ceiling installation by aligning the one or more notches on the panels and slideably connecting the panels. The resultant collapsible acoustic honeycomb ceiling installation can provide a versatile decorative feature to a space while maintaining or altering the acoustics of the space as desired. Further, because the ceiling installation is collapsible, a manufacturer or installer can easily transport, install, and remove the ceiling installation.

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.
