Plasterboard and gib board are two common types of wall and ceiling materials used in construction, but they differ in their composition and brand names.

Plasterboard is a generic term that refers to a type of building material that consists of a gypsum plaster core sandwiched between two layers of paper. It’s also known as drywall or wallboard, and it’s commonly used for interior walls and ceilings.

Gib board, on the other hand, is a specific brand of plasterboard that’s produced by the New Zealand-based company, Winstone Wallboards. The term “gib board” has become a colloquial term for plasterboard in New Zealand, much like how “Kleenex” is often used to refer to facial tissue in the United States.

While plasterboard and gib board are made from similar materials, there are a few key differences:

1. Thickness: Gib board tends to be thicker than standard plasterboard, which makes it more durable and resistant to impact.
2. Tapered edges: Gib board has tapered edges, which allows for easier installation of joint compound and joint tape.
3. Brand-specific accessories: Gib board has a range of brand-specific accessories, such as corner beads and fasteners, that are designed to work seamlessly with the product.
4. Availability: Gib board is primarily sold in New Zealand, while plasterboard is a more universal term used worldwide.
