(Cl. 154-45) The present invention relates to a new insu-' lating material and to a new wall structure embodying such insulating material. More particularly, the present invention relates to an insulating material which may be readily installed in wall structures which are designed to have air spaces, the present material serving to partition said air spaces, thereby multiplying the heat resistance of such air spaces several fold. By means of the preferred form of the present invention the heat resistance of the air space is still further increased by minimizing the transmission of radiated heat through such air spaces.

The insulating material I propose to use and the structures I propose to form will utilize the above principles and will form a very effective and emcient insulation, will be very easy to install, and can be fabricated very simply on a large scale and at a very low cost. This form of insulation can be applied to the walls and roofs of all types of building structures, and can be easily made to fit into all comers as under gabled roofs. This material will also be found to meet all requirements in the insulation of I railroad cars, ships, refrigerator cabinets, automobile bodies, airplanes, cold storage warehouses and other structures which require eflicient and light weight insulation.

It will, therefore, be understood, that wherever the term w appears in the following specification and claims, it applies to all such structures which contain insulating air spaces.

The new insulating material of the present invention consists of a web of sheeted fibrous material, such as building paper or similar material which is so prepared that a severed portion of the web may be installed in an air space with great facility so as to subdivide the air space into a plurality of parallel air spaces. For this purpose, the web consists of several plies which are free of each other except along the edges and are so attached or associated that any length of the web may be severed and readily installed in an air space as by the attachment of the edgesin the preferred form the alternate plies are' covered on one or both sides with a metal coating, such as metal foil, preferably aluminum foil, for the purpose of minimizing the transmission of radiated heat. Unooated material may, of course, be employed if desired.

The material is preferably made available to the trade in roll form; nevertheless, when desired, it may be made available in severed lengths so that each such length may be said to constitute an insulation panel for installation in insulation spaces.

Fig. 1 shows one form of the insulating material. In this i'orm the web 20 of insulating material forms a roll.2l. The overall width of the web is somewhat in excess of the customary spacing of studding in a building frame. If the material is to be employed in other structures, then the width of the web 2| is somewhat greater than the spacing of the supporting members therein.

The web 2| consists of three plies 22, 23, 24, all of the same width. The outer plies 22 and 24 -.re each coated with metal or metal foil 29, preferably on both faces, and each has marginal strips 25 and 26, respectively, which .are uncoated. The intermediate ply 23 is preferably unooated and also has uncoated marginal strips 21. In each of the sheets crease lines 20 serve to facilitate the bending of such marginal strips during the installation of such webs and their attachment to the supports.

Each ply is attached to an adjacent ply only .along one edge or marginal strip, the other edge remaining free in the case of outer plies, or, in

the case of intermediate plies, the other edge is attached to the other adjacent ply. Thus, in the form shown herein, the outer ply 22 has one strip 25 free, and has its other strip 25 attached tome adjacent strip 21 in the intermediate ply 23,-,which in turn has its other strip 21 attached to the strip 26 in the ply 24, while the opposite strip 26 is free. Thus, the plies are free of each other along their surfaces so as to provide air spaces bordered by such plies. The attachment between the strips 25 and 21 and between the strips 26 and 21 may be accomplished by staples 28' or by sewing, pasting, or in any other suitable manner.

The manner in which this material is employed now becomes apparent from the showing of Fig.

3 which is a schematic horizontal-partial section of a wall and comprises studding 30, sheathing or siding 3! which may be of any suitable material and wallboard, plastic board or any other facing material 32. In the course of construction, studding 30, 40 is first erected and sheathing or siding 3| is then applied to the exterior of the studs. In the employment of the present material, before the inner facing 32 is applied, a suitable length of the material 20 is cut from the roll 2|, and installed in the space between the adjacent studs as shown in Fig. 3. The marginal strip 25. is tacked to the stud at the far corner as shown. The intermediate marginal strips are tacked to studs 40 and 30 as shown, and the last free marginal strip 26 may be tacked on the face of stud 40 or on-its side but adjacent the front face as desired. Thus, by means of the present material and with the aid of simple operations involving only atacking operation, the large air space becomes divided into four smaller air spaces, thus substantially multiplying the heat resistance of the space four fold; and in addition the insulating material provides at least one face of metal for each air space, thereby substantially eliminating the transfer of radiated heat. across such air spaces.

It will be understood that the material is employed in substantially the same manner in cell.- ings, in which case, 30 and 40 may be said to represent joists, and also in roofs in which case 30 and 40 may be said to represent rafters. The present material may thus be employed in any and every insulating space.

It will also be understood that where the spaces happen to have peculiar shapes, the material 20 may be cut from the roll to suit the shape.

Under some circumstances, it may be sufficientmerely to tack the free marginal strips as shown in Fig. 3 and leave the intermediate strips untacked, for the material will occupy the condition shown in Fig. 3 even when the intermediate strips are untacked.

Fig. 4 shows another form of the invention. In this form the plies instead of being made of separate webs are all made of one wide web ll which is divided into three longitudinal zones 42, 43, and H. The zones 42 and 44 are each coated with metal foil 45 or with metal paint or with any other form of metallic coating for reflecting radiant heat on both faces while the intermediate zone 43 remains uncoated.

such portions to form intermediate attachment strips as shown in Fig. 3. Thus, an installation of a severed portion of the web II will look the same as that shown in Fig. 3 except that the intermediate attachment strips are integral with each other. 1

Another form of fabric or web embodying the present invention is shown inFig. 6; Fig. 7 shows a severed portion of this w b ready for installation in an air space.

The web 60 shown comprises three plies SI, 62, 63 having bent-up marginal strips 64, 65, 86, respectively; so disposed that when attached by means of staples 61, or by any other means, they form three spaced layers. The plies BI and 63 are preferably coated with metal foil or with metal bronze as shown at 69. Fig. 8 shows this material installed in an air space between adjacent studding by means of the tacks It, thus dividing the air space into severed air spaces, each bounded by a metal surface, preventing the transmission of radiant heat.-

simple tacking operation. All the forms shown herein may be employed either with or without the metal coating.
