The track is elongate such that it extends along a longitudinal axis. The track comprises an alignment feature located at a predetermined alignment position along the longitudinal axis of the track. The alignment feature is configured to secure a partition support member at the alignment position when the partition support member is received by the track. The alignment feature comprises one of a projection or recess configured to engage with the other of a projection or recess of the partition support member.

A core/base layer, an intermediate layer, a divider layer between the core and intermediate layers, and a water-resistant layer on the intermediate layer opposite the core layer. The core and intermediate layers are made of a cementitious material to provide structural-strength and fire-resistance properties, with the core layer including an aggregate material for added strength, the intermediate layer including an hydrophobic additive for water resistance, and the divider layer positioned between the core and intermediate layers to form a physical barrier that prevents cross-migration of the aggregate material and the hydrophobic additive between these layers. The water-resistant layer includes a fiber-based carrier layer with an outward-facing surface having a weather barrier layer secured to it and with an opposite uncoated inward-facing surface having loose fiber strands extending from it and embedded into the intermediate layer to secure the water-resistant layer to the intermediate layer.

An overhead grid assembly for a suspended ceiling system and a bracket member thereof. The overhead grid assembly may include first and second support members having first and second longitudinal axes that are arranged in an intersecting manner to form a grid. The bracket member may include a first part having a first channel and a second part having a second channel. The bracket member is arranged to maintain the first and second support members in a desirable orientation relative to each other. Thus, a portion of the first support member may nest within the first channel and a portion of the second support member may nest within the second channel. The first and second parts of the bracket assembly may be rotatable relative to one another to ensure that the bracket assembly can be coupled to the first and second support members regardless of their relative orientation.

A panel assembly for a suspended ceiling system, an adjustable corner bracket thereof, and a method of assembling such a panel assembly. The panel assembly may include a ceiling panel having a groove in its rear surface, a plurality of suspension bars disposed within the groove along the sides thereof, and a plurality of corner brackets disposed within the groove along the corners thereof. The corner brackets may include a first arm portion extending along a first arm axis and a second arm portion extending along a second arm axis. The corner brackets may be adjustable to alter an angle measured between the first and second arm axes so that the corner brackets may be used in different grooves having different shapes.

Edge profile 10 for forming a part of a suspended ceiling substructure comprising a plurality of support profiles arranged suspended from a raw ceiling of a building structure and a plurality of base profiles, each of which being attached to at least one of the plurality of support profiles, the edge profile 10 having a U-shaped cross-section with a base portion 11 capable of being fixed to a wall structure, a first leg portion 12 and a second leg portion 13, the first leg portion 12 having an outer section 122 and an inner section 121, wherein the outer section 122 is arranged offset towards the second leg portion 13 relative to the inner section 121.
