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 9.4 to 112 lb/ft³ (150 to 1800 kg/m³), with λD from 0.34 BTU·in/(h·ft²·°F) (0.049 W/(m·K)) and strengths up to 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 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 0.079 to 0.236 in (2-6 mm), low water absorption, coated with E.I.A. additive.
