ARIETE 825 CE

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

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 0.079 in (2 mm)) coated with the E.I.A. additive. At 51.5 lb/ft³ (825 kg/m³) 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 (2 in (5 cm), 68 °F (+20 °C), 50% RH).

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