istics. A most important characteristic of the wall of this invention lies in the improved ability of the wall to absorb sound waves and the improvement in this respect is believed to be due to the flexible, though apparently rigid, multi-layer s material which, though unitary with respect to application to thewall, includes separate adherent layers of material of wholly different characteristics, plus a surface or exposed lightecolored film or layer adherent thereto.
Prior to this invention, it has been suggested that a sound-deadening wall might include porous material in layer form, for example, cloth or felt, and such material, after being attached to a plaster or other equivalent permanent wall backing, was then treated when in place to provide an ornamental surface. Such suggestions, however, have not been adopted generally and practically to any appreciable extent and, moreover, involve hand labor and expense and considerable time after being attached before the wall can be provided with an acceptable light-colored surface as is required for home construction. The present invention, however, provides a complete and substantially finished wall and one which advanu tageously may be used at once with or without additional treatment, and at the same time provides the all important sound-deadening characteristics to which the invention is particularly directed.
In the accompanying drawings which form part of this specification:
Fig. l is a front elevation, with parts broken away, illustrating our invention;
Fig. 2 is a vertical transverse section of the wall of this invention; and
Fig. 3 is a perspective view illustrating the novel sound-deadening material and the manufacture thereof. 7
Referring to the drawings in which like numerals represent like parts, the usual permanent outside wall of a building is generally indicated at 2 and, as here shown, includes studding l, sheathing 8, heat-insulating paper 1, and shingles or the like! on the outside of said insulating paper or the like.
To the inside of such permanent wall 2, there is attached by nails 9 or other suitable fastening to the studding l, or equivalent structure, a wall board backing l0 and adhesively secured thereto by an adhesive layer of cement l2, sodium silicate for example, is a unitary multi-layer, flexible sound-deading material, generally designated at ll. Said unitary multi-layer material It comprises an open porous layer of rag and paper (water-laid) felt l6 having corrugations II, as hereinafter more fully described, to which felt ,IB is adhesively attached, by means of a layer of flexible and preferably water-proof cement It, a water-proof layer of felt 20. Preferably the water-proof layer 20 is saturated with asphalt which saturant itself or asphalt additionally applied fiexibly and adhesively attaches said waterproof layer 20 to theopen or porous layer It, though rubber or other flexible cements will adequately serve. The water-proof layer 20 carries upon its outside surface a light-colored flexible and ornamental pigmented layer or layers 22 which are adhesively held to the layer 20 by reason of the binder or binders in said layer 22. In practice and preferably said ornamental layer 22 is made up of two layers applied'to and made a part of the unitary multi-layer material at the time of manufacture thereof and prior to the combining and adhesive attachment together of the layers It and 20 by the flexible cement l8. It has been found in practice that the waterproof layer 20, even when previously waterproofed by being saturated with asphalt in an amount equal to or greater than its own weight, may be provided with a light-colored or even white pigmented surface by coating the asphalt saturated layer with a water-emulsified linseed oil paint, and hence in the absence of any thinner which would have a solvent action on the underlying asphalt or like black hydro-carbonaceous materiaiwhich solvent thinner, as in an ordinary oil paint, would cause a staining of the pigmented surface by reason of its solvent action on said asphalt or the like. Moreover, such layer is found in practice to be sufllciently tough and flexible as to permit a reasonable amount of bending of the unitary multi-layer material so that it may be bent around corners as small as a radius of say "/8" for the outside corners where the paint layer is in tension and a radius of or even smaller, for inside corners where the paint layer is in compression. If desired, however, to obtain an even better and smoother finish, an additional and flexible coat of oil paint including a hydro-carbon solvent is preferably applied to the coat of wateremulsified paint just mentioned and it has been found that the coat of water-emulsified paint, when dried, effectively provides a barrier layer .between the solvent of such after-applied paint and the preferred asphaltic saturant of the layer- 20. If desired, the layer 22 may be so pigmented, applied, or indented as to provide the appearance of a rough plastered or stippled or textured surface. In order to provide sufficient flexibility for the relatively thick unitary multi-layer sounddeadening material so that it may be rolled and unrolled without substantial fracture or cracking of the material when so rolled and unrolled and during the application thereof to the wall board backing, it is highly desirable and in most cases necessary that the said layer l6 be corrugated or indented by a series of parallel lines and/or continuous or discontinuous indentations ill, the lines of such corrugations or the like being at right angles to the length of the material and parallel to the axis of the roll. In the preferred product in which each layer has a minimum thickness of at least .020 and is preferably .026" to .040" the corrugations or indentations may suitably be in parallel lines approximately A or thereabouts apart. Such a layer further tends to better bridge any small irregularities in the wall board backing, and such dry felt material though possessing little inherent strength is sufficiently stiffened and held in place by the asphalt saturated layer 20 of relatively high tensile strength and stiffness. The aggregate thickness of the finished product including the light-colored layer or layers 22 is of the order of .070" to .075" which gives adequate thickness and characteristics for the sound-deadening as heretofore described, as well as suf icient stiffness and body to provide a durable and attractive wall having the novel and useful characteristics as herein described.
The sound absorption capacity of a wall made in accordance with this invention as above described, is found to be much greater than that of an ordinary plaster wall made up of lime or gypsum plaster including scratch, brown and finished coats on wood-lath. The figures of ac tual tests made of such sound absorption coefd= cients are as follows:
Sound cycles 128 256 512 i024 2040 Our structure .070 .160 .210 .380 .330 Ordinary gypsum plaster .020 .022 .032 .039 .039 Ordinary lime plaster .024 .027 .030 .037 .010
In addition to such striking sound absorption characteristics, the wall, in practice, is found to have very good heat insulating characteristics. Moreover, it forms a ready and practical substitute for plaster construction at a substantial saving in the cost of lath, plaster, labor and necessary drying time, before woodeninterior trim may be installed. Besides, the wall is permanent Without any likelihood of cracking or other failure due to excessive swelling and shrinking such as inevitably result from the application of wet plaster, and does not shatter due to vibration and shock as does an ordinary plaster wall.
