KEYSTONE allows more freedom of design where the warmth and beauty of NATURAL STONE is desired. It is WEATHERPROOF, COLOR FAST and has exceptionally HIGH INSULATING VALUES. It has a very HIGH COMPRESSIVE STRENGTH, and when applied properly, has a SHEER STRENGTH far in excess of that required by the UNIFORM BUILDING CODE and F.H.A. When properly installed it will last the lifetime of the building with no undesirable changes in color or appearance.
