The present invention aims to provide a build lathing material, such as expanded metal, or the like. One of the objects of the present invention is 5 ing material which comprises Within it perma- ' nently assembled the desired elements _so that the to provide a self-furring metal lathing material. Thus the present lathing material when applied same serves as a plaster lath, and as an insulat-y against the studs or sheathing on the inside or outside lof a frame wall or against a brick wall provides an air space lbetween the lathing mate ing building material, and so that when the same is nailed by the'customary operation in the build rial and the wall. the wall with an air space between the wall and ing art against the wall and ñrrnly attached to , Another object of the present invention is to provide such a self-furring lathing material which will have a substantially monoplanar plaster-receiving front face and which will be 15 the lath, the lath provides a substantially con tinuous plaster-receiving face and at the same substantially free of all obstructions on its plas ter-receiving face so that the plasterer may per with metal such as aluminum or aluminum foil.l time this material embodies a heat-reflecting building paper such as a building paper coated Any suitable lathing material may be employed> in the construction of the p_resent building ma terial. As illustrated in the accompanying draw is to provide a metal lath which also constitutes 20 ing, the expanded metal lath I0 is employed in the` present assembly. Such lathing material an insulating building material. For this pur permits the plaster to enter the openings in thepose,'the metal lath is -backed by a ilexible sheath material and thus becomes located with and to form insulating material in the form of a building the lathing material. In the present invention paper coated with aluminum or aluminum foil. The aluminum coatedr building paper, with the 25 the back face of the Vmetal lath I0 is lined with the building paper II which may be in the form'v aluminum coat on its rear side, namely, on the of any suitable asphalt coated paper, or kraft side exposed to the wall, serves to reflect radiated paper, or any other suitable paper. On its back heat and prevent the transmission of radiated heat across the air space between the lathing and 30 face, namely, on the face that would be exposedv to the Wall, thebuilding paper II lis adhesively the -wall. covered with aluminum foil I2. The paper lying The present invention further aims tovprovide against the back of the metal lath will prevent metal lathing material Which is combined with the extrusion of excessive amounts of plaster a- metal coated building paper so as to convert through the openings in the metal lath. thelathing into an insulating material, the com In order to maintain the aluminum coatedl bination or structure being such as to prevent , building paper and the metal lath in iixed and any of the plaster or any of the liquids in the permanent assembly, the metal lath'is provided` plaster vfrom gaining access to the aluminum with rearwardly extending ribs. These are pref v coating on the building paper. Such liquids erably parallel to each other _and extend either would corrode the aluminum foil or any other 40 lengthwise or widthwise‘ ofthe metal lath, as,` aluminum coating on‘the building paper. In the desired. It will be noted that ’theser ribs I3l are form the plastering operation with facility. A still further object of the present inventionV present invention, therefore, furring or spacing strips or grips are employed which serve to grip, fix, and ñrmly attach the metal coated building paper onto the back of the metal lath. ` - formed by crimping the metal lath. While these 45 ribs or >crimped portions should lextend entirely " across the‘dimension' of the sheets of metal lath, their depth may be varied. » . ' Other objects and advantages of the present Essentially the depth of the rib or crimping invention will be understood by persons skilled should be large enough so that it may be gripped in the art from a reading of the following speci by the spacing or furring strip I4. The furring ñcation and from the accompanying drawing strip I4 may be employed in the form of the which illustrates the present invention. 50 spaced short sections. It is preferred, however, In the drawing: that the same be coextensive with the ribs I3 so Fig. 1 is a diagrammatic cross section of the that thereby it may offer rigid support to thatl lathing material; portion of the metal lathing.
