  • Patent number: 9040153
    Abstract: Sag in ceiling tiles is reduced by the present coated ceiling tile and method which decreases sag in the coated ceiling tiles. Calcined gypsum and water are combined to form a coating which is applied to the back side of a base ceiling tile in a thin layer of about 100 micrometer to about 1000 micrometers. The coating optionally includes a set time modifier. This method makes a coated ceiling tile from a base ceiling tile having a front side and a back side opposing the front side. The coating is applied to the back side of the base ceiling tile, the coating comprising an interlocking matrix of calcium sulfate dihydrate. Optionally, remnants of the set time modifier are present within interstices in the gypsum matrix. The remnants of the set time molecule include ions, molecules, particles or combinations thereof.

  • Patent number: 8337976
    Abstract: An abuse-resistant, cast acoustical ceiling tile having improved impact resistance and excellent sound absorption values. The ceiling tiles have aggregate particles applied to the surface of a wet pulp in the casting process and the particles are embedded in the pulp by compression with a roll and/or smooth plates. The aggregate particles have an average particle diameter of at least about 1,000 microns. The ceiling tiles have excellent sound absorption properties with a noise reduction coefficient (NRC) of at least about 0.50. Calcium carbonate is the preferred aggregate particle material.

  • Publication number: 20120291388
    Abstract: An elongated grid runner, and its manufacture, comprising a pair of overlying metal strips roll-formed together into a shape suitable for use in a rectangular grid to support ceiling panels, one of said strips serving as a visible cap for concealing the other strip forming the main body of the grid runner when the grid member is employed in a completed ceiling, the strips being lanced at each end of the grid runner to lock the cap strip on the main body strip whereby when the overlying strips are simultaneously cut to a finish length prior to finish roll-forming, the ends of the strip are maintained in substantially overlying end-to-end registration where the cap is visible in a finished ceiling.

  • Publication number: 20120137615
    Abstract: A suspended ceiling comprising a grid formed of intersecting grid runners and snap-up panels supported on the grid runners, the grid runners dividing a ceiling area into standard modules, the pans being formed of sheet material and each having its sides sized to cover the module size while leaving a space at visible faces thereof between adjacent panels when in an installed position on the grid, at least one adjacent pair of panels being displaceable from their installed positions, the gap between a pair of displaceable panels being closed by a removable runner or the displaceable panels so that when the displaceable panels are displaced from their installed position and any removable runner is removed, an access opening of twice the standard module is made available for accessing the area above the ceiling while adjacent panels at longitudinal ends of the gap between the displaceable panels can remain in respective installed positions.

  • Publication number: 20120076983
    Abstract: An interior surface panel such as a ceiling tile is free of PVC materials and otherwise possesses desirable properties that make it suitable for installation in a variety of environments including schools, household and commercial kitchens and healthcare facilities. The panel can include a base mat and a facing material of a polyolefin or polyester polymer or copolymer bonded to the base mat. The facing material is resistant to ultraviolet light and possesses superior scrubbability. The PVC-free facing has a preferred thickness, opacity and surface roughness and a texture pattern that is non-directional and discontinuous. In an embodiment in which the PVC-free facing is white, it has a preferred light reflectance. The PVC-free facing is resistant to deformation under tension. In addition, the facing has low anisotropy; that is, the facing exhibits minimal differences in its physical properties in different directions. The facing also has good dimensional stability.
