  • Patent number: 11898345
    Abstract: The present disclosure relates generally to acoustic panels, for example, suitable for use in a ceiling to control sound. The present disclosure relates more particularly to an acoustic ceiling panel including an acoustic substrate formed of a porous material having an air flow resistivity of at least 300 kPa*s/m2. The acoustic substrate includes an upper face and a lower face with a pattern of perforations formed therein, where the pattern of perforations covers at least 6% of the area of the lower face. The acoustic ceiling panel also includes a backing layer disposed over the upper face of the acoustic substrate and a veil disposed over the lower face.
    Type: Grant
    Filed: March 15, 2021
    Date of Patent: February 13, 2024
    Assignee: CertainTeed Ceilings Corporation

  • Patent number: 10858829
    Abstract: The present disclosure relates generally to suspension ceiling grids, for example, suitable for holding a suspension ceiling composed of ceiling tiles. The present disclosure relates more particularly to a vented suspension ceiling support beam including an elongate body extending in a longitudinal direction. The body includes a vertical web, and opposing first and second flanges protruding laterally from the vertical web. A vent is formed through the first flange.

  • Patent number: 10240634
    Abstract: A component for a bearing including a substrate having opposite major surfaces spaced apart by a thickness of the substrate, and a plurality of channels extending along the first surface, at least two of the plurality of channels extending in parallel with each other, wherein at least one of the plurality of channels is adapted to receive and secure a polymeric material to the substrate. A method of forming a bearing including providing a substrate having a opposite major surfaces spaced apart by a thickness, forming channels in the substrate, the channels each having a depth extending from the first major surface toward the second major surface, applying a polymeric material to at least a portion of the first major surface, wherein a portion of the polymeric material occupies at least a portion of at least one of the channels, and curing the polymeric material.
