1. A shear panel building material comprising:
- a first facing membrane and a second facing membrane, wherein the first facing membrane and the second facing membrane are independently selected from the group consisting of paper, metal and metal alloys;
a rigid material situated between the first facing membrane and the second facing membrane, said rigid material being self-supporting; and
a core matrix sandwiched between the first facing membrane and the second facing membrane, wherein the core matrix includes;
from about 25 wt % to about 60 wt % of microspheres based on wet formulation, the microspheres having a size of from 100 to 1500 microns, wherein the microspheres are consisting of cenospheres, each cenosphere comprising an outer surface and a hollow interior filled with gas;
from about 20 wt % to about 36 wt % sodium silicate binder; and
from about 5 wt % to about 15 wt % organic binder, wherein the microspheres are bonded together by the sodium silicate to create a plurality of voids between the microspheres,wherein the rigid material is held in place with respect to the first and second facing membranes by the core matrix.

Abstract
A shear panel building material that includes a first facing membrane, a core matrix disposed on a face of the first facing membrane, and a semi-rigid or rigid material attached to the core matrix. The core matrix can include microspheres having a size of about 200 microns to about 800 microns, sodium silicate, and ethylene vinyl acetate. In one aspect, the shear panel is substantially free from glue and cement.
