Drywall
Gypsum-based panels used to create interior walls and ceilings
Drywall
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 San Diego'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
