Cement / wood wool boards


novolit magnesite / woodwool board

There are various types of cement/wood wool board combinations with Heraklith (which uses a magnesite cement) being one of the better known makes in the UK. Although the cement component is a cause of embodied energy, there are several ‘green’ advantages which count in its favour

  • high timber content
  • no problem with waste disposal (unlike plasterboard)
  • no harmful gases or vapours given off with no toxic fumes if burnt
  • safe to work with

Added to this is a useful set of advantages to the designer

  • a ‘breathing’ material (vapour permeable)
  • dimensionally stable and good in compression
  • resists moisture attack
  • good as a substrate for renders and other finishes
  • good fire qualities
  • good sound absorbing qualities
  • quite good thermal insulation properties

some suppliers are Heraklith and Skanda

    I had used Woodwool-cement boards without any form of painting at all in 2005 and, till today, they are still in excellent condition. Good luck!

    Can these be painted with breathable paint rather than plastering/rendering them?
