Liner Unit


Square or taper edge plasterboard bonded to various types of insulation which provides an insulated internal lining for walls and ceilings offering improved sound reduction and smooth plasterboard internal finish.


  • Insulation satisfies the requirements of BS 5422.
  • Plasterboard is incombustible to BS 476–4, rated Class 1 surface spread of flame to BS 476-7.
  • The gypsum plaster facing material should not be used in continuously damp conditions or externally on a building.

Product Options


  • Expanded Polystyrene (EPS): Versatile expanded polystyrene for optimum value and light weight.
  • Extruded Polystyrene (XPS): Small, closed cell extruded polystyrene for optimum insulation, high compressive strength and resistance to moisture.
  • Lamella (LAM): Manufactured from high density rock wool slab, which is cut into blocks and rotated through 90° before being bonded to the plasterboard. Lamella rock wool is incombustible and is especially suitable for acoustic applications.
  • Polyurethane (PUR): Polyurethane foam has very low thermal conductivity and is particularly suitable for applications where space is at a premium.

Aluminium foil vapour barrier:

Available with aluminium foil vapour barrier between plasterboard and insulation.
