What is Gypsum Block vs Stone

Gypsum blocks are hollow units made of gypsum and a binder of vegetable fiber, mineral fiber, or wood chips.  Never used where they would be subjected to moisture, they are suitable for non-load-bearing, fire resistant interior partitions. 

Another use is as a fire proofing material around structural steel beams and columns.  They are usually finished with a plaster coating.  Easily cut and light weight, gypsum blocks are relatively inexpensive to install.


Differences with Stone:

All types of stone are used in buildings.  The most important ones used in the construction industry are granite, sandstone, slate, limestone, and marble.  Building bricks are small masonry blocks of inorganic non-metallic material hardened by heat or chemical action.  

Building bricks may be solid or may have core openings to reduce the weight.  Bricks are produced in a wide variety of colors, shapes and textures.  Many builders use gypsum blocks in their construction projects for added flair and protection.
