POLITERM® BLU

ULTRA-LIGHTWEIGHT THERMALLY INSULATING AGGREGATE, PRE-COATED WITH E.I.A. ADDITIVE. BEAD Ø 3-6 MM

POLITERM® BLU is Edilteco's ultra-lightweight aggregate for producing lightweight thermally insulating subfloors and screeds on site with just cement and water. It covers services, levels the slab, forms slopes and insulates, while weighing as little as a tenth of a traditional subfloor: the solution for new build and renovation, including timber floors and structures with limited capacity for additional loads.

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.

With the same product you obtain densities from 9.4 to 112 lb/ft³ (150 to 1800 kg/m³): from maximum lightness (λD 0.34 BTU·in/(h·ft²·°F) (0.049 W/(m·K))) up to compressive strengths of 3,626 psi (25 N/mm²). Up to 21.8 lb/ft³ (350 kg/m³) you only need 2 bags of 14.8 ft³ (420 L), cement and water, no sand. It needs very little mixing water and dries quickly (about 2.5 days per inch of thickness (1 day per cm)).

It is mixed in a cement mixer or horizontal mixer and pumped to the floor with POLITERM® MACHINE, ISOLCAP MACHINE or screed pumps. It contributes to impact sound insulation (ΔLw up to 26 dB) and is class A2-s1,d0 for reaction to fire.
