A brand name for drywall or gypsum wallboard, consisting of gypsum plaster core sandwiched between paper facings used for interior wall and ceiling construction.

Sheetrock is a brand name for drywall or gypsum wallboard, consisting of gypsum plaster core sandwiched between paper facings used for interior wall and ceiling construction, serving as the primary method for creating smooth, paintable surfaces in modern building construction. This essential building material, manufactured by USG Corporation, has become so widely used that the brand name is often used generically to refer to all gypsum wallboard products, regardless of manufacturer. Sheetrock is fundamental in interior construction where it provides fire resistance, sound control, and smooth finished surfaces while offering efficient installation methods that have revolutionized wall and ceiling construction, making it the standard choice for residential, commercial, and institutional buildings where quality interior finishes are required.

Sheetrock is utilized in various interior construction applications including residential wall and ceiling systems where it creates smooth surfaces for paint, wallpaper, and other finishes, commercial buildings where it provides fire-rated assemblies and acoustic control, institutional facilities including schools, hospitals, and offices where durability and performance are critical, renovation projects where it updates existing spaces with modern wall and ceiling systems, specialty applications including curved walls, soffits, and architectural features where formability is important, and fire-rated construction where specific Sheetrock products provide required fire resistance ratings. Each application requires appropriate product selection based on performance requirements, environmental conditions, and building codes.

The types and specifications of Sheetrock products include regular drywall for standard interior applications with paper facings and gypsum core, moisture-resistant (green board) products for areas with moderate humidity exposure, fire-resistant Type X drywall that contains glass fibers for enhanced fire protection, abuse-resistant products with reinforced cores for high-traffic areas, mold-resistant formulations that resist mold and mildew growth in humid conditions, and specialty products including flexible drywall for curved applications, sound-dampening products for acoustic control, and lightweight formulations for easier handling. Product selection depends on specific application requirements and performance needs.

Fun Fact: Sheetrock was invented in 1916 by USG Corporation as a replacement for traditional lath and plaster construction, revolutionizing interior wall construction by reducing installation time from days to hours.
