- the support rails 60 which may be fashioned of sheet metal, plastic or the like, are provided with spaced apart cutout sections for the reception of a clip member 66 having oppositely extending wing portions 68 and spaced apart downwardly depending spring leg portions 70.
- the leg portions 70 are adapted to functionally engage the inner surfaces 20 of the edge regions 14 of the adjacent panels 10.
- the support rails 60 are initially suspended across the entire space in which the ceiling panels 10 are to be installed.
- the centerrnost panels 10 are positioned, and the installation thereof continues toward the sidewalls of the room. Upon reaching the sidewalls, the outermost panels 10 may have to be trimmed.

- FIG. 7 illustrates semischematically the method of forming or molding the panel or tile.
- the molding apparatus includes a bottom die or platen 74 and an upper die or platen 76, the dies being mounted in a conventional press for relative movement toward and away from each other.
- the dies or platens 74 and 76 are preferably heated by electrically energizable heating means 78, but they may be heated by fluids such as heated air circulated through passages in the dies or by other means.
- a loose mass or pelt 80 of glass fibers or other suitable fibers impregnated with a heat-curable or settable binder is disposed between the dies when they are in the illustrated position.
- the fibrous mass or pelt 80 is initially of a thickness of about 2 inches of loose randomly oriented fibers as they are delivered from a conventional glass fiberforming apparatus onto a conveyor.
- the glass fibers may be formed by the method and apparatus disclosed in Slayter, et al. US. Pat. No. 3,026,563, or by other conventional fiber-forming process. Fibers of various diameters may be employed, providing the fibers are flexible. It has been found that glass fibers of an average diameter or size of about 0.00028 inches are preferred, but fibers of lesser or greater diameters may be employed. Fibers of increased diameters tend to impair the fidelity of design.
- the fibers may be of varying lengths, for example in a length range of from one-half inch to 8 inches or more, or continuous fibers of filaments may also be used.
- the fibrous mass 80 is impregnated or provided with a suitable uncured binder such as phenolformaldehyde or other binder suitable to retain the fibers permanently in molded configuration, the binder being usually applied as the fibers are formed.
- a suitable uncured binder such as phenolformaldehyde or other binder suitable to retain the fibers permanently in molded configuration, the binder being usually applied as the fibers are formed.
- the mass or uncompressed body or pelt of fibers 80 is of very light density, being about 1 pound per cubic foot and is of substantially uniform thickness enabling the use of a conventional mat of fibers from a fiber-forming station to effeet economical production of tiles or panels even though the fibers are compressed in the molding operation to different densities and thicknesses in various regions in forming the panels or tiles.
- the obverse surface or face of the panel or tile may be provided with a layer or facing of resinous film such as a vinyl film (copolymer of vinyl chloride and vinyl acetate) or other plastic film.
- resinous film such as a vinyl film (copolymer of vinyl chloride and vinyl acetate) or other plastic film.
- a vinyl film or other plastic film 82 is disposed on the loose fibrous mass 80 in the manner illustrated in FIG. 17.
- the mass of fibers may be molded to tile or panel configuration without a resinous film or facing layer.
- the upper or female die or platen 76 is fashioned with a surface 86 bounded by four rightangularly arranged surfaces 88, one of which is shown in FIG. 17. Two of the opposed surfaces 88 are in converging relation with a surface 90, and each of the surfaces 90 intersected by an angularly arranged surface 92 terminating in a sharp edge 94 which trims the tile to size when the dies are closed.
- the lower or male die 74 is fashioned with an upper surface 96 bounded by an upwardly extending peripheral ridge 98 of square contour.
- the exterior surface 100 of the ridge intersects a surface 102 parallel with the surface 96.
- the surfaces 88 of the upper dies form the exterior surfaces of the edge regions 14, while the surfaces 100 of the lower die form the interior surfaces 20 of the edge regions 14.
- the panels or tiles may be formed by this method either with or without the resinous film layer 72.
- the film may be in a range of from 1 to 8 mils in thickness and is preferably of a thickness of about 4 mils.
- the fibrous mass 80 lying on the lower die, is heated substantially before the dies are brought to closed position. This action results in differential temperatures between the upper and lower regions of the tile causing warpage.
- the upper die is maintained at a higher temperature than the lower die so as to more nearly equalize the heating of upper and lower sections of the tile and thereby prevent warpage.
- the temperature differential is approximately For example, if the upper die is at a temperature of 440 F., the temperature of the lower die would be about 430 F.
- the average curing time that is, the time that the dies are held in closed or tile-molding position, is approximately 1 minute and 30 seconds for curing tiles without a resinous film facing 82. This curing time is sufficient to set the phenolformaldehyde binder.
- lower curing temperatures are employed.
- the upper die may be heated to approximately 375 F., and the lower die maintained at a temperature of approximately 360 F., providing about a 150 temperature differential between the upper and lower dies.
- the dies are maintained in closed heat-curing relation for approximately 2 minutes in order to effect a proper curing or setting of the binder.
- the amount of binder in the fibrous mass is preferably in the ratio of between 3 percent and 25 percent by weight of the fibrous glass mass, the ratio of binder to the fibrous component being dependent upon the desired thickness and degree of rigidity of the central section 12 of the panel or tile.
- FIGS. 1 to 4 The following is exemplary of dimensions and structural characteristics of one form of a molded fibrous panel, illustrated in FIGS. 1 to 4, made in accordance with the method of the invention which is of comparatively lightweight having effective thermal insulating properties and sound-attenuating characteristics.
- the height of the panel 10 is of the order of three-eighths of an inch in thickness, the compressed fibers in the central section being of approximately a density of between 14 and 18 pounds per cubic foot.
- the fibers in the edge regions 14 of the panel are compressed to a higher density of approximately 30 pounds per cubic foot and are of a thickness of approximately one-sixteenth of an inch.
- the fibers at the bridge sections 16 are compressed to a density of about 60 pounds per cubic foot and ofa thickness of about one thirty-second of an inch.
- the fibers of the central section of the panel 10 compressed to the aforementioned density provide a central section which is substantially rigid, and by reason of the highly compressed fibers in the edge regions 14 and the bridge regions 16, the central section 12 is substantially reinforced by the rigid edge regions and warping of the panels substantially militated against.
- the panel 10 of the type illustrated in FIGS. 1 to 4 has effective acoustic or sound-attenuating characteristics even though the central section 12 is of substantial density.
- the acoustic characteristic or noise-reducing property of a body is generally expressed as N.R.C. (noise reduction coefficient). It is found that the noise reduction coefficient of the fibrous section'l2 is from 0.50 to 0.60, which is indicative of comparatively high acoustic or noise-reducing properties. Where the central section 12 is compressed to a lesser density, the acoustic properties may be improved but the rigidity factor of the section is reduced.
- FIGS. 8, 9, and 10 illustrate a modified form of the panel or tile illustrated in FIGS. 1 to 4, wherein the panel or tile 10 embraces a central section 12', comprising a body of glass fibers or other fibers compressed to a desired density and thickness.

- Two opposite edge portions 14 of the panel or tile 10' are provided with integral beadlike indexing projections or extensions 25 and 25, which typically extend over only one-half of the dimension of the associated respective edge 14'.
- the surfaces of the projections 25 and 25 adjacent the outer wall of the edges 14 are adapted to extend over the free marginal edge of the edge regions 14; of the adjacent panels 10' when the same are installed in a ceiling system, to thereby effect the desired alignment of the panels.
- the width of each of the projections 25 and 25' is substantially equal to twice the width of one of the edges 14'. Therefore, when the panels are joined in abutting relation, a fastening means such as the clip member 66 illustrated in FIGS. 5 or 6, may be readily fitted over the edges T4 in securing relation thereon to support the panels in a ceiling system.
- the panels or tiles 10 and 10' may be fastened to an overhead support system by other fastening means such as that illustrated in FIG. 11, for example, wherein the panels 10 are supported from a suspended overhead support rail 100.
- the support rail 100 is adapted to be suspended in spaced relation below a main overhead supporting structure, such asjoists, for example, by hanger wires 102.
- the support rail 100 is provided with spaced apart cutout sections for the reception ofa clip member 104 formed of a blank of sheet material folded or bent upon itself to form a pair of substantially parallel spaced apart leg portions 106 joined at their distal ends by a web portion 108.
- Each of the leg portions 106 is provided with outwardly extending rib 110 suitable for engagement with a similar aperture in the support rail 100.

- the edges or edge regions 14" are integrally joined with the central portion or section 12" by bridge portions 16".
- the bridge portions 16" of fibers are typically of substantially the same thickness and density as the edge regions 14".
- the central section or portion 12" is defined by angular surfaces 18" at the four edges of the central section or portion 12'', and the inner surfaces 20 of the edge regions 14".
- the inner surfaces 22" of the edges 14" adjacent the bridge portion 16 are arranged at an angle in converging relation with the angularity of the surfaces 18", forming channels or grooves 24".
- the pairs of surfaces defining the grooves 24" are arranged in converging relation to facilitate the molding operation in forming the panel and to assure a better flow or orientation of the fibers in the bridge portions 16" and the edge regions 14".
- the terminal ends of the edge regions 14" of two adjacent edges of the panel 10" are fashioned in the form ofa hooklike configuration in cross section 15.
- the thickness and density of the fibrous material constituting the edge regions 14" and the hooklike sections 15 are substantially identical.
- FIG. 15 One method of suspending the panels or tile 10", illustrated in FIGS. 12, 13, and 14, is illustrated in FIG. 15 wherein the hooklike section 15 of one panel is positioned over a wire 112, after which the edge 14" of another panel 10" is forced into the space between the interior of the hooklike portion 15 and the outer surface of the edge 14" of another adjacent panel 10" and is maintained by frictional engagement.
- FIG. 16 Another method of supporting the panels or tile 10" is illustrated in FIG. 16 wherein the hooklike section 15 of one panel is positioned over an upturned end 114 of strap member 116 formed of sheet material such as sheet metal, for example.
- the strap member 116 is typically secured to a main overhead supporting surface such as joists 118 by nails 120, for example.
- the edge region 14 of another panel 10" is forced into the space between the outer surface of the upturned end 114 of the strap member 116 and outer surface of the edge 14 of the panel 10" having the hooklike section 15.
- the frictional engagement of the straight edge 14" of one panel with the hooklike section 15 of the other cooperating panel is sufficient to maintain the same in suspended supported relation.
- FIG. 17 illustrates still another method and means for supporting the interlocked panels 10 of the type illustrated generally in FIGS. 15 and 16, wherein there is provided a sheet material supporting or suspending member 122 having spaced apart depending leg portions 124 having longitudinally extending beads 125, wherein the leg portions are joined at one end by a laterally extending base section 126 which may be fastened to a main overhead supporting surface such as joists 128 by nails 130, for example.

- FIG. 18 there is illustrated an arrangement for suspending the panels or tiles 10" wherein the hooklike portions 15 are disposed adjacent one another and are caused to be fitted over respective upturned terminal ends 132 of transversely extending flanges 134 of a hanger member 136.
- the hanger member 136 is suspended from an overhead support by spaced hanger wires 138.
- the surfaces 86 and 96 of dies 76 and 74, respectively, are illustrated as being smooth and uninterrupted, it will be understood that the surface 86 may be provided with a pattern to impart a textured appearance to the obverse surface of the finished panel. In such instance the central portion of the finished panel will be comprised of zones of different densities. If it is desired to obtain uniform density throughout the textured portion of the panel, each of the die surfaces 86 and 96 are provided with matched patterns. The density of the control portion of the panels generally falls within the range of from 15 to 25 pounds per cubic foot. In order to obtain the maximum design fidelity in the panels containing textured surfaces, it is found desirable to impart a greater density to the fibrous mass when employing a small design than when employing a relatively larger design on the die surfaces.
