PROMATECT®-L500

PROMATECT®-L500 is a non combustible low density calcium silicate board, used for the construction of fire resistant ducts, and to provide fire rated cable and service enclosures.

PROMATECT®-L500 is off white in colour and has a smooth sanded surface on one face with a lightly honeycombed texture on the reverse face.

PROMATECT®-L500 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, and while untreated surfaces will absorb water which can cause some loss of strength full strength is regained after drying. It will not encourage mould growth and is resistant to attack by insect or vermin.

PROMATECT®-L500 is chemically inert and is resistant to dilute acids and alkalis.
