1. A shear panel building material comprising:
- a first facing membrane;
a second facing membrane;
a rigid material situated between the first facing membrane and the second facing membrane, said rigid material being self-supporting; and
a core matrix disposed between said first and second facing membranes, said core matrix including;
from about 25 wt % to about 60 wt % of microparticles based on wet formulation,from about 20 wt % to about 36 wt % sodium silicate, andfrom about 2 wt % to about 6 wt % of a vinyl acetate,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.
