Types of Drywall

Regular (white board): Standard interior walls and ceilings. Cost: $10-$15 per 4x8 sheet. Most common type.
Moisture resistant (green board): Paper face treated for moisture resistance. Cost: $12-$18 per 4x8 sheet. For bathrooms, kitchens, laundry rooms. Not for direct water contact (use cement board for showers).
Mold resistant (purple board): Fiberglass face (no paper for mold to grow on). Cost: $15-$25 per 4x8 sheet. Best for high-moisture areas. Brand: National Gypsum Purple XP, Georgia Pacific DensArmor.
Fire resistant (Type X): Contains glass fibers for fire resistance. Cost: $12-$18 per 4x8 sheet. Required: between garage and living space, between units in multi-family. 5/8 inch thick provides 1-hour fire rating.
Soundproof: Multiple layers with damping compound. Brands: QuietRock, SilentFX. Cost: $40-$60 per 4x8 sheet. STC rating 50+ (vs 33 for standard drywall).
Specialty: Abuse-resistant: fiber-reinforced for high-traffic. Flexible: for curved walls (1/4 inch). Ceiling board: sag-resistant for ceiling applications.

Standard Sizes

Thickness: 1/4 inch: flexible, for curved surfaces and overlays. 3/8 inch: repair and layering. 1/2 inch: standard for walls (most common). 5/8 inch: standard for ceilings (sag resistant) and fire-rated.
Sheet sizes: 4x8 feet: most common, easiest to handle. 4x10 feet: reduces seams in 9-10 foot walls. 4x12 feet: reduces seams, harder to handle. 4x14 and 4x16 feet: commercial, requires multiple people. 54-inch wide sheets: ceiling applications (fewer seams).

Hanging Drywall

Tools needed: T-square and utility knife. Drywall screws (1-1/4 inch for 1/2 inch drywall). Drill or screw gun. Drywall lift (for ceilings, rent for $40-$60/day). Keyhole saw or rotary tool (for outlets and switches).
Hanging sequence: Ceilings first, then walls. Top sheets before bottom sheets (top sheet supports upper edge). Horizontal orientation for walls (stronger, fewer seams at standing height).
Screw pattern: Every 12 inches along edges. Every 16 inches in the field (center of sheet). 3/8 inch from sheet edge minimum. Screws should dimple (slightly below surface) without breaking paper.
Cutting: Score face with utility knife along T-square. Snap board along score line. Cut back paper with knife. Openings: measure and cut with keyhole saw or rotary tool.
