Why Wallboard?
- Wallboard, also known as standard plasterboard, is a widely used interior surfacing panel for walls, ceilings and applications where standard levels of fire resistance, structural support, and sound insulation are required.
- It is composed of a gypsum core sandwiched between two thick sheets of paper.
- One of these paper faces has a characteristic ivory colour, providing a clean and neutral backdrop for decoration.
- Whether you prefer the simplicity of paint, the intricate patterns of wallpaper, or the texture of a plaster finish, wallboard provides the perfect foundation.
Why 12.5mm?
- 12.5mm plasterboard is the standard thickness for most construction projects, offering a balanced combination of strength, durability, and ease of installation for general wall and ceiling applications.
- It provides better structural integrity and sound insulation than the lighter 9.5mm board, while being less bulky than the thicker 15mm option.
- However, unless specified as a performance board, it should not be relied upon as a standalone solution for soundproofing.
Why Square Edge?
- Square edge plasterboard features a clean, straight edge, making it ideal for areas where joints will be concealed with joint compound, tape, trims, or mouldings.
- Commonly used in non-structural applications such as internal wall linings and ceilings, it is well-suited for spaces where additional finishing is planned.
Why 1800mm x 900mm?
- 1800mm x 900mm plasterboard offers a more compact and manageable size compared to standard 2400mm x 1200mm sheets, making it an excellent choice for projects where ease of handling, transport, and installation are crucial.
- Its smaller dimensions are particularly advantageous in tight spaces, rooms with limited access, or smaller renovation projects where manoeuvring larger sheets could be challenging.
- Additionally, the 1800mm size helps reduce material wastage, making it an efficient option for more precise, smaller-scale applications.
