More about Historical Common Product: Type X Drywall - 2015

Drywall is ubiquitously used in building construction as interior wall enclosures, ceilings, and partitions in both load-bearing and non-load-bearing cases. There are many strains of Drywall including but not limited to acoustical, fire-resistant, moisture-resistant and mold-resistant varieties. This Common Product profile represents a Type X (fire resistant) Drywall product. Drywall is composed of gypsum plaster pressed between a paper or cardboard lining. The key material is gypsum (calcium sulfate), which is available in different hydration levels, and in anhydrous form. Natural gypsum stone is calcium sulfate-dihydrate (CaSO4*2H2O). The anhydrous calcium sulfate can be found in nature as anhydrite (CaSO4). Gypsum also occurs in large quantities as the industry by-product, otherwise known as flue-gas desulphurized (FGD) gypsum. This common product profile includes a combination of natural mined gypsum, FGD, and post-consumer gypsum. Type X drywall has greater thickness and special core additives (mainly vermiculite, fiberglass, and kaolin clay) which provide additional fire resistance, higher rigidity, and enhanced sound attenuation as compared to regular ½” gypsum board. 5/8” (16mm) type X North American gypsum boards are manufactured to ASTM C1396, Standard Specification for Gypsum Board.
