PROMATECT®-L500
PROMATECT®-L500 is a non-combustible low density calcium silicate board, used for the construction of fire resistant ducts. It is a Class 0 product as defined in the Building Regulations.
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. Untreated surfaces will absorb water which can cause some loss of strength, but full strength is regained after drying. It will not encourage mould growth and is resistant to attack by insect or vermin.
