POLITERM® BLU FEIN

ULTRA-LIGHTWEIGHT THERMALLY INSULATING AGGREGATE, PRE-COATED WITH E.I.A. ADDITIVE. BEAD Ø ≤ 2 MM

POLITERM® BLU FEIN is the fine-bead version (Ø ≤ 0.079 in (≤ 2 mm)) of POLITERM® BLU, for lightweight thermally insulating subfloors and screeds made on site with cement and water. The fine bead gives a more homogeneous and compact mix and a smoother surface, while still weighing as little as a tenth of a traditional subfloor.

It is made of EPS beads coated with E.I.A. additive: the additive makes the beads mix perfectly with cement, stops them floating and spreads them evenly through the mix, at low and high densities alike. The result is a lightweight concrete that does not settle, does not shrink and does not crack. It is the only RAL-certified aggregate. It is the only product that makes self-leveling lightweight thermally insulating mortars possible.

With the same product you obtain densities from formula 110 (about 8.1 lb/ft³ (130 kg/m³), λD 0.29 BTU·in/(h·ft²·°F) (0.042 W/(m·K))) up to 112 lb/ft³ (1800 kg/m³) and 3,626 psi (25 N/mm²). It needs very little mixing water and dries quickly (about 2.5 days per inch (1 day per cm)).

It is mixed in a cement mixer or horizontal mixer and pumped with POLITERM® MACHINE, ISOLCAP MACHINE or screed pumps. Reaction to fire A2-s1,d0.
