ARIETE 825 CE

PRE-MIXED, CE-MARKED, LIGHTWEIGHT, THERMALLY INSULATING SCREED. 825 kg/m3 (51.5 lb/ft³)

ARIETE 825 CE is a pre-mixed, CE-marked lightweight thermally insulating screed made of special hydraulic binders, selected aggregates and virgin EPS beads (Ø 2 mm (0.079 in)) coated with the E.I.A. additive. At 825 kg/m³ (51.5 lb/ft³) it weighs less than half as much as a sand-cement screed, cutting the load on the structure.

With C5-F1 strength it works as a single-layer screed: floor coverings are glued directly onto it, saving thickness and a whole working stage. Ceramic, stoneware and clinker can be laid after approx. 6 days, floating parquet after approx. 12 days (5 cm (2 in), +20 °C (68 °F), 50% RH).

It also insulates: λD 0.176 W/mK (1.22 BTU·in/(h·ft²·°F)) and an impact sound improvement of ΔLw 19 dB when combined with DBRED FONOTECH 5.
