In an aspect a method of manufacturing a ceiling panel is described. The method may include: combining a binding agent with plastic flakes; passing the plastic flakes and the binding agent to a lamination machine; applying a force to the binding agent and the plastic flakes using the lamination machine to create a plastic sheet; and adding a decorative ceiling treatment to a first side of the plastic sheet.

Described herein are acoustical panels, comprising: a substrate; a non-woven veil having an airflow resistance of greater than 45 mks rayls, comprising: from about 20 wt. % to about 60 wt. % glass fibers; from about 40 wt. % to about 80 wt. % of a filler; and from about 110 dry g/m.sup.2 to about 135 dry g/m.sup.2 of a coating. Methods of making and using the panels are also described.

The invention relates to a method of making an acoustic product and a novel acoustic product, wherein the acoustic product is made by adhering a facing to a first major surface of an acoustic insulation element by the use of an adhesive and curing the adhesive. The adhesive is an aqueous adhesive composition which comprises a component (i) in form of one or more oxidized lignins; a component (ii) in form of one or more cross-linkers; a component (iii) in form of one or more plasticizers.

This invention relates to a suspended ceiling, comprising a metal grid structure and a plurality of drop-in ceiling panels supported by the metal grid structure. Each of the ceiling panels includes a thermal conductive metal substrate, a heat insulating coating formed on the top surface of the metal substrate, and a thermal conductive ceramic coating formed on the bottom surface of the metal substrate. The heat insulating coating is provided to prevent heat generated in a plenum space between the dropped ceiling and a actual ceiling from traveling down to the room below the dropped ceiling. And, the thermal conductive ceramic coating is provided to enhance a heat transfer capability of the metal substrate. As such, the ceiling panels can facilitate rapid cooling of an air-conditioned room.

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.

The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a nonwoven facing and to methods for making such panels. A method for preparing an acoustic panel comprises providing a base structure. The base structure has one or more edges, an outward major surface having total area, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The method includes disposing directly against the outward major surface of the base structure a sprayable mixture comprising a plurality of fibers, one or more binders, and a dispersive medium. The method includes drying the disposed mixture to provide a facing layer disposed on the outward major surface of the base structure, the facing layer having an exterior major surface opposing the outward major surface of the base structure.

The present invention is enclosed in the area of acoustic treatment, therefore solutions for adapting/tuning the acoustic performance of a space, wherein such space may take very varied forms: a living space such as a living or sleeping room (100), a lobby or a recording room (100). It is an object of the present invention a sound tuning layer which is PE based and obtained from the steps of sublimation of a PE based starting material with an open cell structure, and subsequent cold pressing, said cold pressing being performed at a lower temperature as regards the sublimation step, and while the sublimated sound tuning layer is still hot, and thereby forming the sound tuning layer, with an open cell structure. It therefore provides a more environmentally friendly and simple solution than those of prior art.

Described herein is a laminate acoustic panel comprising a first layer and a second layer, as well as a ceiling system that includes the laminate acoustic panel.

Systems and methods are disclosed for a multi-layered sound absorption structure. The multi-layered sound absorption structure may include a form material, an acoustic material disposed on a surface of the form material, and a construction material disposed on the acoustic material. The acoustic material may couple to the construction material during curing of the construction material. After the construction material is cured, the form material may be removed exposing a least a portion of the acoustic material.

Provided is a ceiling tile coated on at least one surface with an acoustically transparent coating which creates pores at the tile surface and comprises a high Tg polymeric binder, titanium dioxide, and particles selected from the group consisting of void latex particles, hollow glass beads, calcium carbonate, calcium magnesium carbonate, calcined clay and any combination thereof. Compositions for acoustically transparent coatings and methods for making a substrate surface acoustically transparent are provided as well.
