15mm Knauf Wallboard Plasterboard Applications

15mm Knauf Wallboard is a cost-effective solution specifically purposed for installation in partition walls and ceilings. The boards can be easily fixed to various brick or masonry backgrounds with drywall adhesive (via the "dot and dab" method) or they can be mechanically fixed with drywall screws to timber and metal partitions. Generally speaking, the boards are suitable for most applications where normal fire, structural and acoustic levels are specified and normally require skimming.

  • Partition applications
  • Lining applications
  • Ceiling applications

Knauf Wallboard Tapered Edge - The Benefits

There are a few key reasons why tapered edge plasterboard is generally considered to be a better option than square edge plasterboard: 

  • Much easier to create smooth, professional-looking finishes when jointing and skimming
  • Makes it easier to achieve a seamless finish between sheets
  • Generally much easier to work with overall, meaning that you are less likely to make mistakes when installing it
  • When the boards are butted up together there is a slight depression where they meet that you can fill with plasterboard joint filler to conceal the joint


Please note: joint treatment should be allowed to dry before commencing with any decorator's preparatory work or direct decorations.
