Prefabricated panels used to cover wall framing and create smooth interior surfaces, commonly known as drywall or gypsum board.

Wallboard is prefabricated panels used to cover wall framing and create smooth interior surfaces, commonly known as drywall or gypsum board through manufactured sheets that provide fire resistance, sound control, and finished wall surfaces ready for paint or other decorative treatments. This fundamental building material consists of gypsum plaster core sandwiched between paper or fiberglass facings that create flat, uniform wall and ceiling surfaces while offering structural support, fire protection, and thermal properties. Wallboard is essential in modern construction where it provides cost-effective interior finishing, enables rapid construction, offers fire safety benefits, and creates smooth surfaces for decorative finishes, making it indispensable for residential and commercial buildings, renovation projects, and any interior construction where efficient wall finishing and fire protection are necessary for building performance and occupant safety.

Wallboard is utilized in various construction applications and building systems including interior wall construction where it covers wood or steel framing to create finished room surfaces, ceiling installation where it provides smooth overhead surfaces and conceals structural and mechanical systems, fire-rated assemblies where it contributes to fire resistance ratings for walls and ceilings, sound control systems where it provides acoustic separation between spaces, moisture-resistant applications where specially treated boards resist humidity and moisture damage, and specialty installations including curved walls, high-abuse areas, and impact-resistant applications where enhanced performance characteristics are required. Each application requires appropriate board selection, installation methods, and finishing techniques based on performance requirements and environmental conditions.

The types and specifications of wallboard include regular gypsum board that provides standard performance for most interior applications, moisture-resistant board that offers enhanced protection in bathrooms and high-humidity areas, fire-resistant board that provides extended fire ratings for fire-rated assemblies, impact-resistant board that withstands abuse in high-traffic areas, sound-dampening board that provides enhanced acoustic performance, and specialty products including mold-resistant, lightweight, and flexible boards for specific applications. Product selection depends on application requirements, building codes, and performance needs.

Fun Fact: Wallboard revolutionized construction when introduced in 1916, replacing time-consuming plaster walls and reducing interior finishing time from weeks to days, with modern wallboard containing recycled materials and offering enhanced performance characteristics.
