POLITERM® R

ULTRA-LIGHTWEIGHT THERMALLY INSULATING REGRANULATED AGGREGATE, PRE-COATED WITH E.I.A. ADDITIVE

POLITERM® R is the ultra-lightweight aggregate of the EDILTECO GREEN line for lightweight thermally insulating subfloors that reuse material: it is made of regranulated EPS beads. Same performance as a POLITERM® subfloor, with a lower environmental impact.

The beads, coated with E.I.A. additive, mix perfectly with cement and water, do not float and spread evenly. Densities from 150 to 1800 kg/m³ (9.4 to 112 lb/ft³), with λD from 0.049 W/mK (0.34 BTU·in/(h·ft²·°F)) and strengths up to 25 N/mm² (3,626 psi).

It needs very little mixing water and dries quickly (about 1 day per cm). It is mixed in a cement mixer or mixer and pumped with POLITERM® MACHINE, ISOLCAP MACHINE or screed pumps; it can also be mixed and pumped with a truck mixer. Reaction to fire A2-s1,d0. Also available as POLITERM® R Ready Mix, specifically for concrete batching plants.

NOTE

Regranulated EPS beads from virgin industrial offcuts Ø 2-6 mm (0.079 to 0.236 in), low water absorption, coated with E.I.A. additive.
