  • Patent number: 8266860
    Abstract: In one embodiment, a roll-formed sheet metal tee for grid type suspended ceilings with the face of its flange integral with the stem and the layers of the stem fixed together for improved torsional strength. An upper region of the stem can have one or more of its layers folded to increase suspension wire breakout strength. A stiffening bulb is below suspension wire receiving holes so that a loop of the suspension wire through the tee has a narrow profile and thereby avoids interference with ceiling panels during their installation or removal. Other embodiments of a tee share the feature of a narrow, suspension wire receiving upper stem portion.

  • Patent number: 8251175
    Abstract: An acoustical panel construction useful as a suspended ceiling tile having a rectangular shape bounded by edges and establishing a face area comprising at least one corrugated layer or layers of a total thickness, the layer or layers having a multitude of parallel flutes extending across an expanse of the rectangular shape substantially from one edge of the panel to an opposite edge, the flutes being formed by walls of the layer or layers and being of known volume, a series of apertures each of known area through the wall or walls of the flutes communicating with the atmosphere at the face, the aperture area, flute cavity volume associated with an aperture, and the total thickness of the corrugated layers associated with an aperture being arranged to produce a maximum absorption frequency between 200 and 2,000 Hz.

  • Publication number: 20120161058
    Abstract: An acoustic building material and method for manufacture incorporates chitosan in an amount sufficient to achieve acceptable physical properties with a reduction in binder and to allow the postindustrial/postconsumer content of the building material to be increased. The chitosan also enhances the dewatering of the building material.

  • Patent number: 8181412
    Abstract: A preassembled suspended ceiling grid module comprising a plurality of parallel main tees and a plurality of cross tees, the main and cross tees each having horizontal flanges extended to both sides of a central plane, the cross tees being joined at their ends to the main tees with end connections that enable the module to be folded in a plane corresponding to an eventual ceiling plane in a zigzag pattern, such that the cross tees lie in directions generally parallel to the main tees with the cross tees connected on a side of a particular main tee being folded in a common direction relative to their end connection, and where connected to an adjacent main tee being folded in an opposite direction relative to their end connections with said adjacent tee.

  • Patent number: 8182922
    Abstract: An improved economically produced clean room ceiling tile formed as a composite comprising a base board and a finish coated paper facer laminated to the base board. The base board is preferably made with excess thickness and is machined to a desired caliper. The machined board is sealed with a clay coating and thereafter coated with a water-based adhesive. The paper facer is laminated to the board with the water-based adhesive and is finish coated with a water-based wet scrubbable coating. The paper facer is easy to laminate, exhibits excellent coverage of surface defects in the base board surface, is fully compatible with the water-based finish coating, and contributes to the sag resistance of the tile.

  • Patent number: 8147629
    Abstract: A ceiling tile of gypsum and cellulose fibers formed into a board by initially mixing the fibers and gypsum in a water-based slurry that is felted and thereafter pressed and dried with a desired board thickness, the dried board being processed to form a plurality of holes in a face thereof through at least the majority of the thickness of the board, the collective volume of the holes being sufficient to reduce the weight of the board by at least 10% and increase the NRC exhibited by the board over that which would otherwise be found in a board of the same composition without such holes.
