A ceiling system for a clean room, a clean room ceiling and a method for constructing a ceiling for a clean room are provided. T-shaped beams support the ceiling from a building structure. Channels support composite panels on the bottom side of the T-shaped beams. Each of the channels is attached to the top side of a composite panel and each engages a first or second leg of a T-shaped beam. The channels may be Z-channels.

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.

A method of creating a sculpted decorative ceiling with lighting fixtures in a suspended ceiling grid utilizing ceiling components constructed with structural side elements and a floor, forming a cavity that extends downward three to five inches. Each individual component has a perimeter installation flange enabling it to be installed into a new or existing ceiling grid system cell. The said components esthetic contours and functional structural side elements, as well as the size of the perimeter installation flange create space(s) between installed components, throughout an entire ceiling arrangement of said components or in specific areas of arrangements of said components, for luminesce channel(s) in which may be positioned one or more lighting fixtures, or combinations of lighting fixtures, attached to the room facing surfaces of the cross tee or main runner flanges that comprise the ceiling grid structural assembly. Components may have floor perimeter shapes approximately equal in area to the entire ceiling grid cell, or they may have floors perimeter shapes occupying only part of the ceiling grid cell with a filler section at right angles to the structural side elements of the component that extend co-planer to the perimeter installation flange. Ceiling components can come in a variety of floor profile shapes allowing the construction of a wide variety of arrangements in the suspended ceiling grid. The side panels and the floor can be created with a wide variety of decorative surfaces.

A folded architectural panel folded from a flat sheet, the panel having opposite longitudinal ends extending in a width direction, opposite lateral sides extending in a length direction and a depth perpendicular to the width and length directions. The panel includes a first downward fold adjacent one longitudinal end, extending in the width direction, and having opposite fold ends at the respective lateral sides of the panel; a second downward fold adjacent the other longitudinal end, extending in the width direction, and having opposite fold ends at the respective lateral sides of the panel; and a central upward fold at a central portion of the panel between the first and second downward folds; the first downward fold, the second downward fold and the central upward fold enable contraction of the opposite end folds towards each other to cause folding of the first and second end folds and an increase in the depth of the panel at the central portion. The panel further includes two pairs of respective side upward folds extending from the four opposite fold ends of the first and second end folds to the central upward fold such that, with contraction of the opposite end folds towards each other, a respective section of each respective lateral side between two respective fold ends contracts inwardly towards the opposite lateral side and a respective sidewall is formed on each respective lateral side of the panel extending from the respective pair of side upward folds in the depth direction.

The invention relates to a surface covering system, and, more specifically, to an improved linear surface covering system. The improvement includes each plank of the system having multi-directionally cut grooves. The improvement further includes clip projections which conform substantially to a notch formed by the multi-directional grooves. The system also includes an improved splice plate for stabilizing two adjacent planks positioned in end-to-end relation.

Described herein are building panels, ceiling systems, and methods for using the panels and systems. Such building panels comprise a mesh member, a frame member, and a securing member.

A stretched-web structure for producing a false ceiling or a dropped ceiling box in a room, including two flexible webs arranged parallel to one another and fastened stretched between at least one wall, wherein one of the webs is made of polyvinyl chloride and the other web is made of fabric.

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.

Ceiling tile system for acoustic modification.

Ceiling tiles for drop ceilings are disclosed. The ceiling tiles have a main portion that is sized and adapted to fit within a grid of the drop ceiling, and a baffle that hangs down from the main portion. A sheet of tile material may have a plurality of fold lines defined in it that allow the sheet to fold in such a way as to define the main portion and the baffle. In the flat configuration, the sheet of tile material may have the dimensions of a standard drop ceiling tile; in the folded configuration, the ceiling tiles may also have standard ceiling-tile dimensions. A single ceiling tile may have two or more baffles, and those baffles may be staggered in position with respect to one another.
