À propos de ce matériau

Drywall (also called gypsum board, wallboard, or by the brand name Sheetrock) is the standard interior wall and ceiling finish material. Sheets are 4 feet wide and come in 8, 10, and 12-foot lengths, with 4x8 (32 sq ft) being the most common. Standard 1/2-inch drywall is used for walls, while 5/8-inch Type X (fire-rated) is required for garage-to-house walls, ceilings below livable space, and many multi-family assemblies. Lightweight drywall (UltraLight by GP, LightRock by CertainTeed) weighs 20-25% less than standard boards and is much easier to handle on ceilings. Moisture-resistant drywall (green board or purple board) is used in bathrooms and kitchens. Cement board (Durock, Hardiebacker) is required behind tile in wet areas like showers. Standard 1/2-inch 4x8 sheets cost $10 to $15 each, while 5/8-inch Type X costs $13 to $18 each. Longer sheets (4x12) reduce the number of end joints but are heavier and harder to handle.

Conseils de pose

• •Hang ceilings first, then walls.
• •Stagger joints — no H-joints.
• •Use 1-1/4" screws for walls, 1-5/8" for ceilings.
• •Drive screws dimple-deep but do not break paper.

Erreurs courantes à éviter

• ⚠Not staggering joints — H-joints crack.
• ⚠Over-driving screws and breaking the paper face.
• ⚠Running boards parallel to joists on ceilings — perpendicular reduces sag.
• ⚠Skipping the mechanical room wall — always drywall even in unfinished areas.
