La Chape XXs is a lightweight ready-to-use screed. Lightened by virgin polystyrene beads with controlled particle size and coated with E.I.A. (diameter 2-3 mm - 1/8 in), it is also fiber-reinforced and has high-performance mechanical properties for renovating difficult or sensitive substrates.
La Chape XXs is intended to lighten the structures (2 times lighter than a traditional screed), to isolate and to thermally and acoustically treat the different types of existing supports in collective buildings and individual houses in new or renovation work, to make adherent or detached screeds, insulating gullies and sub-screeds, level adjustments, forms of slopes, acoustic insulation against impact noise.
