Given its outstanding performance, GlassRey® is ideal for either direct-applied exterior finishing systems or exterior insulated finishing systems (EIFS) on walls and ceilings as well as substrate for stucco, bricks, and stone finish. Likewise, it is the  ideal substrate for adhesion or mechanic application of expanded polystyrene (EPS) or extruded polystyrene insulation for interior finish that require a moisture, mold or fire-resistant substrate.
