Perlifoc mortar is made from perlite and vermiculite expanded lightweight aggregates. It provides an A1 fire reaction rating and thermal conductivity of 0.29 W/mK. It has a rough appearance and is used for protecting concrete and steel structures, concrete and wood, mixed and ceramic floor structures and metal ductwork. It also permits the formation of firewalls:
—EI 120 partition, an effective fire barrier that impedes propagation. It is 60 mm deep and composed of: a galvanized substructure, Pyroc metal mesh fastened to the substructure, onto which a 35 mm layer of Perlifoc mortar is sprayed, and a 12 mm gypsum board panel finish. It provides acoustic reduction of Rw=42 dB, which can be extended to 50 dB by adding a second substructure of profiles with a rock wool panel and a gypsum board finish layer.
—Vertical concrete block wall, with a fire stability rating of up to EI 240 with a 25 mm layer of sprayed-on Perlifoc mortar. Applications: mechanical system courtyards, elevator shafts, compartmentalization of exit stairs, parking buildings and industrial sheds, etc.
