  • Low moisture absorption,
  • Can be installed on damp walls and in damp cavities,
  • High thermal performance,
  • Stability in the long term usage,
  • High resistance to impact,
  • High quality facing material,
  • Plasterboard offers excellent fire performance and the Polyfoam XPS insulation contains a flame retardant to inhibit localised ignition. 
APPLICATION
  • Internal insulation and lining of masonry walls in new build or refurbishment,
  • Internal insulation and lining of metal frame and timber frame walls in new build or refurbishment, 
  • Housing,

  • Avoid volatile compounds and chemicals such as solvents in contact with the boards.
INSTALLATION

  • Holes for services, other fixtures etc should be cut before fixing the board.
  • Boards can be either sawn or cut with a sharp knife.
  • Linerboard can be fixed to the substrate with adhesive (dabs or around the perimeter) and mechanically fixed or both the methods.
  • With both adhesive and dab fixing methods, two mechanical fixings are required at the top of each board, 25mm in from the edge. They should penetrate at least 35mm into a solid substrate.
  • When fixing to a metal or a timber frame, the studs of the timber frame should be at least 50mm wide and placed at 600mm maximum centres, with additional framing to provide support at all board edges.
  • On a timber frame, the Linerboard is secured by nailing at 150mm maximum centres, at least 12mm in from the board edge. The fixings should be long enough to penetrate at least 25mm into the timber.
  • On a metal frame, the Linerboard is secured using self tapping screws at 200mm maximum centres, located at least 12mm in from the board edge. The screws should be long enough to penetrate at least 15mm into the frame.
  • Standard plasterboard jointing techniques are used to finish the board ready for direct application of paint or wallpaper.
