Definition
Cement board is made of fibre-reinforced cement and fixed on a metal frame like gypsum board, but it tolerates moisture and water, so it is used in bathrooms, behind tiles, and in external ceilings and partitions.
Why it matters on a project
It is a light, fast alternative to blockwork partitions, and better than standard gypsum where water reaches.
Measurement and pricing
In square metres including frame, fixing and joint treatment.
Common mistake
Fixing standard gypsum board behind bathroom tiles instead of cement board or moisture-resistant board.
Frequently asked questions
