General Purpose Boards

Masterboard

Masterboard is a versatile Class O building board, suitable for use in a wide range of internal and semi-exposed applications. It is of limited combustibility and can be used in constructions providing up to 60 minutes fire protection.

Masterboard is a calcium silicate board reinforced with selected fibres and fillers. It is formulated without inorganic fibres and does not contain formaldehyde.

The colour is off-white and the masterboard has a smooth finish on one face with a sanded reverse face. The masterboard is not classified as a dangerous substance, and can be disposed of in an on-site skip.

Properties
