INSULATING MATERIAL. Application filed July 26, 1926. Seria1.No. 124,885.

My present invention has for its object but showing a slight modification of the 55 to provide an extremely simple and highly insulating material;

It is, of course, understood that the above described insulating material is placed in a building before the lath and the plaster is applied.

What I claim is:

1. An insulating material made up of a plurality of correlated sheets having substantially parallel and perpendicular portions forming a parallelogram, said perpendicular portions serving to space said parallel portions, said sheets having extensions aflording attaching flaps.

2. The structure defined in claim 1 in perpendicular porinto position between said tions of the sheets are flexibly connected-t0 permit saidmaterial to be collapsed and folded in fiat condition.

3. The structure defined in claim 1 in further combination withalongitudinal s acing web attached to the parallel portions of said sheets and connecting the same.

4. The structure defined in claim 1 in further combination with a longitudinal spacing web attached to the parallel portions of said sheets and connecting the same and to which the parallel and perpendicular portions of the sheets are flexibl connected to permit said material to be collapsed and folded in flat condition.

5. The structure defined in claim 1 in which said sheets are scored in the joints between their parallel and perpendicular portions.

6. The structure defined in claim 1 in which said sheets are permanently connected at their attaching flaps.

In testimony whereof I affix my signature.
