PROMATECT®-AD
PROMATECT®-AD is a non combustible low density calcium silicate board, used for the construction of fire resistant ducts, cladding of sheet metal ducts and to provide fire rated cable and service enclosures. PROMATECT®-AD is off gray in colour and has a smooth sanded surface on one face with a lightly honeycombed texture on the reverse face. PROMATECT®-AD 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. PROMATECT®-AD is chemically inert and is resistant to dilute acids and alkalis.
