Why Vapour Plasterboard?  

  • Vapour plasterboard is designed to manage moisture and prevent condensation in high-humidity areas. 
  • Its foil-facing serves as a vapour barrier, blocking moisture-laden air from passing through and causing issues like dampness, mould, or mildew. 
  • The foil’s low permeability and reflective surface work together to maintain consistent temperatures and reduce the risk of condensation on cold surfaces. 
  • Ideal for kitchens, bathrooms, and utility rooms, vapour plasterboard enhances moisture control, boosts thermal efficiency, and contributes to a healthier, energy-efficient environment.

 

Knauf Vapour Panel is not recommended for areas of high humidity, as prolonged exposure to moisture may compromise its performance and integrity. For high-humidity environments, use moisture-resistant alternatives like Knauf Moisture Panel.

 

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 moldings. 
  • 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.

  • Knauf Drywall's dedication to quality and compliance is reflected in their extensive gypsum product portfolio.

Storage & Handling

  • Store boards horizontally to prevent warping or sagging. 
  • Shield boards from direct sunlight and extreme temperature fluctuations. 
  • A cool, dry, and well-ventilated storage area is ideal. 
  • Avoid direct contact with the ground. 
  • Store boards on a level surface, such as pallets or timber supports, to prevent moisture absorption and damage.
