Y 9 Claims. (Cl. 108-8) This invention relates to weather protecting covering and particularly pertains to a covering composed of sheets, strips or individual shingles which are constructed with a foundation portion having a layer of granular mineral material on the expc sable surface and a layer of thermal insulating material on the opposite surface. When the sheets are laid with the edges of adjacent sheets in overlapping relation or the strips or individual elements are laid in overlapping courses, there is provided a plurality of layers with the thermal insulating material between layers of protective material. Thermal insulation is provided by the inherent. character of the material applied to the undersurface of the covering and by providing an irregular surface in the insulating covering or in the surface to which it is applied.

-For a better understanding of the invention, reference may be made to the accompanying drawings in Which- Fig.v l is a cross-sectional view -of one 'of the weather protecting elements which compose the weather protecting covering;

Fig. 2 is a. cross-sectional view of another embodiment;

Fig. 3 is a cross-sectional view of a roof or siding covering composed of elements such as shown in Fig. 1, laid in overlapping courses;

Fig. 4 is a top plan view of a section of weather protecting covering; and

Figs. 5, 6 and 7 are plan views of the underside face of sections -of other embodiments of the invention.

Referring specifically to the drawings in which like numerals are used to designate like parts,

numeral l designates a foundation fabric, felted or woven, which is impregnated with a bituminous vsaturant such as asphalt, tar and the like and is then coated on opposite sides with a layer 2 and a layer 4 of bituminous material. The bituminous material is usually of higher melting point and of a higher consistency than the saturating material and is preferably applied in substantial amounts to provide sulcient thickness for receiving granular material which is preferably applied thereto. Mineral granular material 3 is applied to the coating 2. This is any type of natural or artificial granular mineral material such as soapstone, mica, slate granules, crushed rock or crushed shells, ceramic granules or any suitable nre or weather resisting material. The underside which is the coating 4 has a suitable insulating material applied thereto. This may be in the form of elastic granules such as gran- 55 ulated cork, vermiculite or the like which is a non-conductor of heat, does not radiate heat, is waterproof, light and a highly eilicient thermal insulating material. Where the weather surfac- '5 ing material is in the form of sheets which are to be rolled, granular cork material is preferable because it permits rolling of the sheet. If the material is to be in theform or strip or individual shingles or siding elements, either flexible 10 or rigid, the insulating material 5 may be of either granular cork (Fig. 1) or of sheet cork (Fig. 2) and of any desired thickness.

'I'he cork material is inherently-of `an insulating character, but the mechanical structure of the weather protecting covering may be such to give even greater and increased insulating qualities. In order to increase the insulating character, the insulating material or the adhesive coating may be provided with recesses 6 of any form and character. They are shown in this embodistantially more material and without any substantial increase in the weight of the elements. Where the grooves are continuous, it is preferable to have them crosswse to the vertical'direction of the surface to be covered, so that there will be no open channels between the overlapped courses. The above insulating materials are inherently insulating. Therefore, inasmuch as insulating qualities are provided by the mechanical structure materials which are not inherently insulating may be used. For example the undersurface may be coated with the same material used to coat the weather exposed surface.

The invention is particularly effective and advantageous where the roof is made from strips or individual shingles laid according to what is termed the American method or where the roof is of the built-up type, in both of which forms a plurality of layers of the material are applied so asto give a plurality of independent layers of insulating material between layers of protective material, as clearly shown in Fig. 3 wherein the cork layers are separated from each other and interposed between the weather protecting portions of the covering. The undersurface or the heat insulating material of one course is in direct contact with the granular mineral facing of the underlying course, thereby increasing the insulating character of the rooting by reason of the cells or spaces between the contacting portions of the cork material and the granular surfacing. That embodiment in Fig. 6 in addition to the grooves extending in one direction shows grooves extending crosswise thereto and intersecting the grooves 6. This sets oi the bottom surface with numerous individual projections 8, between the intersecting rows of grooves-that provide the contacting surface with the under layer when the elements are laid. The projections are in the form of squares inasmuch as grooves 6 and 1 are at right angles. However, the grooves may be formed at any angles, and the forms of the projections would vary accordingly. There is no limitations to the grooves or projections being of any particular size or form. They may vary as to either.

In Fig. '7, individual recesses 9 are provided, leaving portions of the material surrounding the recesses forming the contacting surface. These recesses are shown in the form of squares, but, as in Fig. 6, it will be obvious that they may be of any other form as described in reference to the projections 8. This is the preferred embodiment for the recesses are disconnected and lnoncontinuous, thereby providing a structure having no open channels between the overlapping courses. This increases the insulating value.-

The invention has been shown and described in connection with that weather protecting covering commonly known as prepared or composition roofing, but it is also adapted to other roof ing material such as wood shingles, cement asbestos roofing materials in which approximately 85% cement and 15% asbestos is used, or slate shingles, etc. As will be readily understood when such materials as wood, cement asbestos or slate roofs and other types of roofing are used, the cork insulating material 5 may be a sheet material of desired thickness to give the insulating qualities desired, cemented to the underside of the other cement asbestos, slate and other roofing materials by suitable adhesive coating l or bituminous material or other suitable adhesives although one of a waterproof character is preferred so as to obviate the possibility of the insulating material becoming loosened from the foundation material by the action of the rain or snow. I have also found that the insulating material may be a sheet of paper or felt such as asbestos or any felted sheet, preferably saturated, constructed with the recesses and/.or projections as above described.

While I have shown the invention particularly as a roofing it will be understood that it is adapted for a wide variety of uses such as siding for buildings, for insulating cars, houses, etc. and can also be usedvas a lining adapted to provide both insulatingand protective qualities. Furthermore, it will be understood that the invention is not hunted to the specific embodiments illustrated and described, but that there may be various changes in details of construction within the purview of the appended claims.
