POLITERM BLUThe complete range of superlight and high thermal insulating aggregates based on pre-coated virgin EPS beads with controlled density. Each bead is coated at production stage with EIA additive. This enables perfect mixing with the water and cement producing an homogenous distribution of beads preventing beads surfacing or bonding together.

MAXIMUMSPEED ANDEASE

WHy chooSE PoLITERM BLUTHERMAL EFFICIENCy

> Low thermal conductivity λ.> Ideal for use beneath underfloor heating UFH.

SPEED OF INSTALLATION

> A single layer instead of the multiple layer build up of traditional insulated concrete slabs.

> 1 m3 can be mixed, pumped and placed in under 5 minutes.

EASy TO PLACE

> Lightweight. Fast and easy to place, spread level and finish.

REDUCED MATERIAL WASTAGE

> Mix, pump and place on site. Make just enough material to suit requirements. No waste concrete to be disposed of. No large wasted insulation board off cuts left around site.

RAPID CURING

> Cures at the rate of 1 cm. thickness per day.> 10 times as fast as traditional screeds allowing

trafficking and finishes to be applied much earlier.

LIGHTWEIGHT

> With design mix densities between 215 and 365 kg/m3 it is ideal for use in intertenancy floor slabs, balconies and flat roofs. Can be laid to falls.

CE MARKING

> From January 1st 2014.

COMPLIANT WITH BS EN 16025-1:2013

> Thermal and/or sound insulating products in building construction. Bound EPS ballasting. Requirements for factory premixed EPS dry plaster (British Standard).

little energy for production and transport,

a lot of energy saved, thanks to its thermal

performances!

Politerm

EPS + 65 mm. screed

PUR + 65 mm. screed

The immediate advantages of the Politerm Blue screed are: Sub base preparation. The base needs to be perfectly

flat in conventional build ups to ensure there are no voids beneath the rigid insulation boards.

Politerm Blu screed is poured directly onto the dpm and takes up any unevenness.

Insulation boards need to be measured and cut to size ensuring minimal gaps between boards. The off cuts contribute to project wastage and costs.

The exact amount of Politerm Blu screed required is pumped directly onto the dpm.

A slip sheet is required over the insulation boards to prevent the screed or concrete mix getting around and between the insulation boards.

Not required using Politerm Blu. A movement joint is required around the slab

perimeter to allow for expansion and contraction. Shrinkage/expansion is minimal in a Politerm Blu

screed. The conventional screed above (65mm thick) will take

65 days to cure. The Politerm Blu screed will cure in just 14 days.

The next diagram shows the EPS insulation required to achieve a U Value of 0.25 W/m2K for a ground bearing floor slab with a P/A ratio of 0.4 and the alternative Politerm Blu screed. Both solutions are 140 mm. thick.

Lower P/A ratios as typified in terraced houses and semi detached require lesser thicknesses of Politerm Blu screeds compared with conventional screeds.
