Drywall
Drywall, also called gypsum board or sheetrock, consists of gypsum plaster pressed between two sheets of paper, used as the standard material for interior wall and ceiling surfaces.
Drywall revolutionized construction by replacing time-consuming plaster application with fast-installing panels. Standard drywall comes in 4x8-foot or 4x12-foot sheets, typically 1/2-inch thick for walls and 5/8-inch for ceilings. The gypsum core provides fire resistance, sound dampening, and a smooth surface for paint or wallpaper. Specialty types include moisture-resistant green board for bathrooms, mold-resistant purple board, and Type X fire-rated drywall.
Why It Matters
Quality drywall installation and finishing directly impacts your home's appearance and durability. Properly hung drywall with minimal seams, secure fastening every 12-16 inches, and expert taping creates smooth, crack-resistant surfaces. In Denver's dry climate, proper joint compound application and sanding are critical—the low humidity can cause faster drying and potential cracking if not done correctly.
Common Applications
- Standard walls: 1/2-inch drywall over wood or metal studs
- Ceilings: 5/8-inch drywall for reduced sagging
- Bathrooms: Moisture-resistant or mold-resistant board
- Garages and fire-rated walls: Type X 5/8-inch fire-resistant drywall
- Curved walls: 1/4-inch flexible drywall for radius applications

Vapor Barrier
A vapor barrier is a moisture-impermeable material installed in building assemblies to prevent water vapor from penetrating walls, floors, or ceilings and condensing within insulation or structural components.
