A suspended ceiling system includes a polygon-shaped ceiling tile and a grid of profiles supporting the ceiling tile, the grid of profiles defining a frame in which the ceiling tile is arranged and supported. The ceiling tile includes a front surface, a rear surface and at least three side edges extending between the front surface and the rear surface. A side edge portion associated with each side edge includes a top tongue, a bottom tongue, and a groove extending along the side edge portion and separating the top tongue and the bottom tongue. The top tongues include engagement surfaces resting on the supporting flanges of the grid of profiles, and a distal end of each top tongue extends beyond a distal end of the bottom tongue such that a bottom section of the ceiling tile is insertable from above into the frame.

The present invention provides a covering panel, such as a floor panel, wall panel or ceiling panel, comprising a substrate and optionally a top layer, whereby said substrate comprises a synthetic material and a filler material, whereby said filler material is comprised in an amount from 15 to 75 wt. % based on the total weight of said substrate. In addition, the present invention provides a process of producing such covering panels.

A module for the production of concrete parts has a row of displacement bodies that are adjacently arranged in a horizontal longitudinal direction (L) and that are clamped captively to a grid structure made of at least two individual grids running in the longitudinal direction (L). Surfaces of the grids are oriented in a transverse or inclined manner in relation to the horizontal. Each of the grids has at least a first and a second longitudinal bar arranged at a distance in parallel to one another and running in the longitudinal direction (L) and a plurality of transverse bars being arranged at a distance from one another and oriented in a transverse or inclined manner in relation to the horizontal. The transverse bars are respectively connected with the longitudinal bars. One of the displacement bodies for each grid has a first and a second retaining device.

An acoustic housing, a light fixture, a suspended ceiling system, and a method of decreasing sound transfer from a light fixture in a suspended ceiling are disclosed. An acoustic hood for a light fixture in a suspended ceiling may include a partially enclosed space formed between a plurality of wall portions. A light fixture may include first and second layers that are coupled to one another and form a partially enclosed space. A suspended ceiling system may include the acoustic hood or light fixture. The method relates to disposing an acoustic housing spaced from the light fixture.

A building structure 1a, 1b, and 1c incorporates an outer wall 6 provided on a lower side of a sloped ceiling 2 in a slope direction, an opening part 5 formed in the outer wall 6, a box-shaped groove part 15 formed at a lower end of the sloped ceiling 2 along the outer wall 6 and having a lower opening 14 opened downward, and an attachment part 17 provided inside the groove part 15 and to which an upper end part of a light shielding material 16 that shields light incident on the opening part 5 is attached, wherein the groove part 15 is a ceiling-embedded type embedded in the sloped ceiling 2, and a lower end of a side plate of the groove part 15 on a side opposite to the opening part 5 is lower than a height of a lower surface of a frame 23 on an upper side of the opening part 5.

Described herein is a building panel comprising a body comprising a first fibrous material comprising inorganic fiber, a non-woven scrim coupled to the body; and wherein the non-woven scrim has a thickness ranging from about 8 mils to about 20 mils.

A method for manufacturing acoustical elements, includes providing a first fibre component in a form of mineral wool and a second fibre component in a form of bicomponent fibres having a core with a thermoplastic outer layer, mixing the first fibre component and the second fibre component, for provision of a mixture, shaping the mixture into single layered tile shaped elements whereby the mixture is compressed with a compression ratio to a compressed state, and fixating the single layered tile shaped elements in the compressed state for obtaining the acoustical elements.

A radiant ceiling panel for air conditioning of a room, including a radiating surface on which a tube system for conducting a fluid, in particular water, along the radiating surface is fixed, preferably directly. The length of the radiating surface exceeds its width by a multiple. The tube system includes at least two portions fluidically connected in parallel, in particular arranged in parallel. The radiant ceiling panel has a fastening system, in particular a rope-like fastening system, for freely suspended fastening to a ceiling, or at least elements for interacting with said fastening system. The at least two portions are guided together and back apart again in an assembly region of the radiating surface.

A ceiling panel for use in a gridwork of a suspended ceiling is provided. The ceiling panel includes a layer of foam insulation. A first facing sheet is positioned on a lower major face of the layer of foam insulation and a second facing sheet is positioned on an upper major face of the layer of foam insulation. A surface covering layer is positioned on an exposed face of the first facing sheet.
