Method for producing a mineral wool product, said method comprising: fragmentising a recycled mineral wool material for obtaining a first fibre component in the form of fragmentised mineral wool material, mixing the first fibre component with a second fibre component for obtaining a fibre mixture, wherein the second fibre component has an average fibre length which is greater than an average fibre length of the first fibre component, subjecting the fibre mixture to needle punching for mechanically binding the first fibre component and the second fibre component, and subjecting the fibre mixture to a compression operation.

The present invention a tile unit (1) for a tile system (100), such as a suspended tile system. The tile unit (1) comprises: a polygon-shaped tile (2); and an edge profile (3); wherein the polygon-shaped tile (2) comprises a first major surface (4) intended to face a room, an opposing second major surface (5), and side edges (2a-d) connecting the first major surface (4) and the second major surface (5); and wherein the edge profile (3) comprises: an elongated structure (6), wherein in an assembled state of the suspended tile system (100): the elongated structure (6) is configured to at least partially fill a gap between the polygon-shaped tile (2) and a neighboring polygon-shaped tile (2), and a surface portion (6a) of the elongated structure (6) extending along a longitudinal axis thereof is intended to face said room. Wherein the edge profile (3) further comprises and an anchor (7) projecting from said elongated structure (6) and insertable into the polygon-shaped tile (2) from one side edge (2a-d) of said side edges (2a-d) such that the elongated structure (6) is arranged along said one side edge (2a-d).

An acoustical panel unit for a baffle ceiling system comprising: a first acoustical panel comprising a coated and/or laminated front surface and a rear surface; a second acoustical panel comprising a coated and/or laminated front surface and a rear surface; a suspension device for suspension of acoustical panel unit, comprising a top engagement member, a bottom engagement member, and a connection member extending between and connected to the top engagement member and the bottom engagement member; wherein the first acoustical panel and the second acoustical panel are arranged with the rear surfaces facing towards each other, wherein the top engagement member engages a top side portion of each the first acoustical panel and the second acoustical panel such that separation of the first and second acoustical panel is counteracted, wherein the bottom engagement member engages a bottom side portion of each the first acoustical panel and the second acoustical panel, wherein the connection member is arranged between the first and second acoustical panel, and wherein the suspension device is arranged to suspend the first and second acoustical panel via the connection member and the bottom engagement member.

A grid of profiles (10) for a suspended ceiling system, comprising a primary profile (100) having a web (108) provided with a connection opening (102), and a first and second secondary profile (200) each having an end provided with a hook-on member (210). The first and second secondary profiles (200) are connected to the primary profile (100) by means of the hook-on members (210) which are inserted into the connection opening (102) from opposite sides thereof for hooked engagement with the web (108) of the primary profile (100). The first and second secondary profiles (200) each comprises a lug (212) extending in the longitudinal direction (L2) of the associated first or second secondary profile (200), which lugs (212) cooperate with the primary profile (100) to define a mounted state of the grid of profiles (10). The invention also relates to a method for dismounting a grid of profiles.
