General Description
PROMATECT®-250 is comprised of autoclaved calcium silicate spheres
(PROMAXON® – a synthetic hydrated calcium silicate in spherical form) bound in a mineral matrix.
PROMAXON® technology provides excellent fire performance in most applications.
PROMATECT®-250 is off-white in colour and has a smooth finish on one face with a sanded reverse face.
PROMATECT®-250 provides an architectural surface ready to receive most forms of decoration.
PROMATECT®-250 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.
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.
