What is type c gypsum board?
Type C gypsum board meets and exeeds the fire resistance requirements of a type x board. It has mineral additives in the gypsum core that expands when exposed to heat. This expansion holds the board together longer during fire exposure. It is referred to by the Gypsum Association as "Improved Type X" board.

What is fire code c drywall?
This boardis similar in composition to Type X drywall, except that it has more glass fibers, and, it has another ingredient in the gypsum core. This ingredient is a shrinkage-compensating additive, a form of vermiculite. When exposed to high heat, the gypsum core shrinks but the shrinkage-compensating element expands at about the same rate as shrinkage occurs in the waterdepleted gypsum. The gypsum core then is more stable in a fire and remains in place even after the combined water in the gypsum has been driven off.
Did the National Gypsum Company make fireproof gypsum wall board with asbestos?
No, gypsum has a natural fire resistance due to the combined molecules of water which it contains. National Gypsum has never used asbestos in its wallboard products. However, it did at one time use asbestos in some of its sprayed-on fire proofing products. That ingredient was removed from their formulation several decades ago.
Where is calcium sulfate found?

4 Common Gypsum Work Hazards and How You Can Prevent Them?
Many individuals don’t realise how frequently they use gypsum. The mineral is composed of calcium sulphate, a chemical having a wide range of applications. The use of it as an additive in foods including ice cream, blue cheese, flour, and white bread has been authorised by the federal Food and Drug Administration. Additionally, gypsum can be found in toothpaste, prescription medications, cosmetics, and orthopaedic casts. Gypsum is a natural fertiliser that gardeners add to soil to improve its workability and moisture-retentiveness. Another advantageous characteristic is a decrease in the soil’s alkalinity’s corrosiveness. Gypsum has a variety of uses, but if not handled properly, it can be hazardous…Read More
