Promatect - H

PROMATECT-40 board

PROMATECT®-H is a non-combustible matrix engineered mineral board

reinforcedwith selected fibres and fillers. It is formulated without inorganic

fibres and does not contain formaldehyde.

PROMATECT®-H is off-white in colour and has a smooth finish on one face

with a sanded reverse face.


PROMATECT®-H can be left undecorated or easily finished with paints, wallpapers or tiles.

PROMATECT®-H is resistant to the effects of moisture and will not

physically deteriorate when used in damp or humid conditions. Performance characteristics are not degraded by age or moisture.


PROMATECT®-H is also produced as bevelled edge panels for suspended

ceilings using a concealed grid system.


A health and safety data sheet is available from the Promat Technical Department and, as with any other materials, should be read before working with the board. The board is not classified as a dangerous substance so no special provisions are required regarding the carriage and the disposal of the product to landfill. They can be placed in an on-site skip with other general building waste which should then be disposed by a registered contractor.
