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