8 Durable Options Instead of Sag Resistant Gypsum Board

16 Jul 8 Durable Options Instead of Sag Resistant Gypsum Board

Are you looking for a strong option for your ceiling or walls? You can choose from eight alternatives: cement board, fiber cement board, magnesium oxide board, glass mat gypsum board, PVC ceiling panels, metal panels, bead board and wood panels, and ultralight drywall. Many builders turn to these materials because sag resistant gypsum board​ is hard to find and is available in limited sizes. Each option, including sag resistant gypsum board​, has its own advantages. They differ in strength, water resistance, ease of installation, cost, and appearance.

Key Takeaways

• Pick cement board, fiber cement board, or magnesium oxide board for strong walls or ceilings. These boards are water-resistant and fireproof.

• Ultralight drywall, PVC panels, and glass mat gypsum board are easy to put up. They are lighter, so you can finish projects faster.

• Think about how wet your room gets, how hard it is to install, and your budget. This helps you choose the best material that will last and work for you.

1. Cement Board

Features

Cement board stands out as a tough and reliable building material. You will find it made from a mix of cement and reinforcing fibers. This board comes in sheets, usually 3×5 feet or 4×8 feet, and has a solid, heavy feel. You can cut it with special tools, and it holds up well under pressure. Many builders use cement board as a base for tile in bathrooms and kitchens. It does not burn, and it does not break down when wet.
