The natural mineral product MicaFort, ground from Muscovite or Phlogopite Mica, is used in the production of wallboards and cladding to

  • improve dimensional stability
  • reduce shrinkage
  • lower weight
  • increase fire resistance and
  • provide thermal insulation properties.

MicaFort: more reasons to use

The plate-like particles significantly reduce shrinkage when jointing cement is drying which is essential when joining mica filled wallboards together.

MicaFort also assists in:

  • the drying process
  • improving flexibility
  • and providing a moisture barrier.

Therefore it is extensively used in fibre cement wallboards. The joint compounds or cement used to join the plasterboard or wallboards also contain mica for the same reason as detailed above plus to give a uniform finish.
