Robinson, 11118 Greenwich Ave, Cleveland, Ohio 44105 Filed Sept. 17, 1964, Ser. No. 397,148 25 Claims. (Cl. 18133) This invention relates to an insulating and acoustical panel structure and particularly to such a structure wherein the panels may be adhered or suspended from a ceiling.
It is an object of this invention to provide an inexpensive, attractive and efficient insulating and acoustical panel structure which is made of low-cost materials, requires minimum maintenance, and may be easily applied either by the use of adhesive or fastening clips.
It is a further object of this invention to provide a novel ceiling and panel structure.
It is a further object of this invention to provide a novel mounting structure.
In the drawings:
FIG. 1 is a perspective view of the panel embodying the invention.
FIG. 2 is a fragmentary sectional view on an enlarged scale taken along the line 2 2 in FIG. 1.
FIG. 3 is a fragmentary bottom perspective view of the panel shown in FIG. 1.
FIG. 4 is a fragmentary perspective view of the top section of the panel.
FIG. 5 is a fragmentary vertical section through a ceiling having the panels embodying the invention adhered thereto.
FIG.6 is a fragmentary vertical section of a ceiling having the panels embodying the invention suspended therefrom.
FIG. 7 is a fragmentary perspective view of a mounting panel utilized in FIG. 6.
Referring to FIGS. 1-4, the insulating and acoustical panel 10 embodying the invention comprises a hollow telescoping sections 11, 12 which are generally rectangular. Top section 11 includes a generally flat top wall 13 and an integral peripheral side wall 14. The major portion of top wall 13 is depressed relative to the upper edge of the side wall 14 to define a well or recess 15 around the top section 11.
The second or bottom section 12 includes a substantially fiat bottom wall 16 and an integral peripheral side wall 17 telescoped over a portion of the side wall 14 of the upper section 11. Side wall 17 is connected to bottom wall 16 by a bevelled portion 13.
Each of the side walls 14, 17 is provided with openings 19, 20 in the overlapping portions thereof which are of small size and adhesive 21 is utilized to fasten the side walls 14, 17 to one another, the adhesive penetrating through the openings 19, 20 to provide an eflicient locking action.
The outer surface of the top panel 11 is provided with a metallic layer 22 which is applied by vacuum deposition and provides heat insulating properties. As shown in FIG. 2, the depthof the layer is greatly exaggerated and may be on the order of one to two ten-thousandths of an inch.
A batt of sound and heat insulating material, preferably rock wool, is adhered to the top wall 13 by suitable adhesives such as an epoxy adhesive. The thickness of the batt 23 is such that a space 24 is provided between the inner surface of the bottom wall 16 and the batt 23. Satisfactory results may be achieved by utilizing a rock wool having a density of about six pounds per cubic foot. A glass fiber batt may also be used having a density on the order of about one pound per cubic foot.
The bottom wall 16 is provided with spaced openings 25 that provide paths for passage of sound within the space 24 to provide sound-absorbing properties.
The sections 11, 12 are preferably made of a fibrous material, preferably wood cellulose fiber. The sections 11, 12 are molded in accordance with well-known techniques for molding fibrous materials. Preferably, a mixture of cellulose fibers, asbestos fibers, and gypsum is formed into a slurry and molded on a form by a vacuum method. Suitable dyes are added to the slurry molding in order to produce the desired appearance of the panel. In addition, a resin is added to the slurry to provide wet strength. A satisfactory resin comprises a melamine-formaldehyde resin such as Parez resin 607 made by The American Cyanamid Company.
After molding, the sections are placed upon forms with the external surfaces exposed and passed through drying ovens. After the sections 11, 12 have been substantially dried and while they are still on the forms, they are sprayed with a suitable flame retardant and again dried. A satisfactory flame retardant may be of the ammonium sulfamate type such as CM flame retardant made by E. I. du Pont de Nemours and Company of Wilmington, Del.
After substantial drying, the sections 11, 12 while still on the forms are treated with a grease and water inhibitor and again dried. A satisfatcory material comprises FC- 805 which is a water soluble fluoro composition made by Minnesota Mining and Manuafcturing Company of St. Paul, Minn. Finally, the sections 11, 12 are dried. If desired, a thin transparent film of polyethylene may be applied by spraying.
The outer surface of the bottom wall 16 may be em bossed during forming or may be otherwise decorated to produce any desirable aesthetic effects.
The panels may be applied to a ceiling either by the use of adhesive or mounting clips.
As shown in FIG. 1, the top wall 13 of each panel in cludes raised molded portions '27 which define pockets 28 at the corners of the panel into which portions 29 of adhesive can be deposited so that the panel can be pressed upwardly against a ceiling (FIG. 5) to mount the panel in position. The pocket 28 locates the adhesive properly for ready installation. In order to facilitate the adhesion of the adhesive to the top wall '13, small openings 28a are provided through the bottom of pocket 28.
Alternatively, each side wall 14 is provided with spaced longitudinally extending slots 31 so that the panel can be suspended from the ceiling 32 (FIG. 6). A mounting channel 33 having a flange 34 is fastened by nails 35 to the ceiling and has projecting tabs 36 which extend into the slots 31 to suspend the panels from the ceiling. At the side walls 37, a molding strip 38 fastened by nails 39 is used to hold the panels.
In order to insure proper alignment, the surface 40 (FIG. 2) of each side wall 17 is preferably shaped as by grinding or shaving to form an accurate surface which will abut to the adjacent surface. This surface preferably tapers upwardly and inwardly so that a sharp line 41 is provided at the area of juncture between side Wall 17 and the bevelled portion 18.
A thin plastic coating 16a is provided on the outer surface of the bottom wall 16 and the bevelled portion 18 of the bottom section 12. The plastic coating may comprise a thin transparent layer of polyethylene applied by spraying. The plastic coating 16a provides a base for further painting as may be required either initially or after prolonged use of the panel, such as the use of vinyl latex paints. The panel may also be used in an air distribution system as a sound and filter element by providing spaced holes in the top wall 13 of top section 11.
It can thus be seen that there has been provided an inexpensive, attractive and efficient insulating and acoustical panel structure which is made of low cost material, requires minimum maintenance and may be easily applied either by use of adhesive or fastening clips. The panel structure results in a neat and aesthetic appearing ceiling.
