Thermal insulation PROMATECT®-LS

calcium silicatepanelinterior

PROMATECT®-LS 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®-LS is off white in colour and has a smooth sanded surface on one face with a lightly honeycombed texture on the reverse face. PROMATECT®-LS 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®-LS is chemically inert and is resistant to dilute acids and alkalis. Applications: PROMATECT®-LS enables independent ventilation ducts with large clear cross-sections and moldings, fire-resistant smoke extraction ducts and subsequent cladding of sheet steel and plastic ducts. Installation ducts for electrical maintenance have been proven to maintain functionality with high fire resistance. PROMATECT®-LS can be also used indoor with high humidity. Benefits: • 30-90 minutes fire resistance • Large spans tested for self supporting ducts • Used in damp or humid conditions • Excellent fire insulation properties Reaction to fire: A1, non-combustible Use Category: Z1, Z2 Approx.
