EPS: Lightweight thermal insulating mortar. EPS beads which are treated with a chemical additive to enable the production of lightweight, thermal insulation mortars of various densities.

Technical Data

Thermal insulation mortar for concrete roof decks, underground floor slabs, basement walls, swimming pools, etc. Lightweight filler for voids or leveling of floor slabs. Cavity fill for steel frame construction.

  • Easy to mix, place and finish.
  • Cost effective.
  • Homogenous bead distribution gives good workability and predictable performance.
  • Good workability enables mixed material to be pumped 100 m horizontally and 30 m vertically.
  • No loss of workability, even when pumped long distances.
  • Mix design variable to produce densities from 200 to 1 000 kg/m3.
  • Compatible with most finishing products and adhesives.

The Springs EPS facility is ISO 9001:2008 accredited.

K-value of 0.065 W/m.K to 0.1 W/m.K depending on density.

Long term to indefinite, subject to appropriate mix design and best practice in application methods.

 Conventional concrete placing equipment.

Bags should be stored in a clean, dry place away from items which could split or damage the bags.

The Springs EPS facility is ISO 14001:2004 accredited. Less material, less energy and less emissions.

1.Zero ozone depleting potential (ODP).

2.Zero global warming potential (GWP)

The material must be mechanically mixed in either a purpose made mixer/pump, conventional concrete mixer or truck-mixer or specialised mortar mixer/pump Placing and finishing equipment: as for normal concrete/screed application.

 Thermal insulation to concrete roof decks should be Politerm Blu, laid to falls at an average thickness of 100 mm reducing to a minimum of 50 mm at rainwater outlets. Preparation, mixing and curing should be carried out in strict accordance with the manufacturer’s instructions. Subsequent application of waterproofing should not commence until the Politerm screed is free of residual moisture.


As a “One-stop Insulation shop” Insulpro CC can offer insulation solutions across all temperature ranges and applications.
