EPS for Construction 

Expanded Polystyrene is the number one choice for your next construction job. 

  • Roof, floor and wall insulation cut to size for sheds and coldroom floors
  • Bridge, rail and road widening schemes. 

EPS for Concreting

Concrete formwork - Void former can be manufactured to most shapes specified by designers for projects such as bridge beams, elevated motorways etc in which void forming is fundamental to modern design.

Drainage (stormwater) - Koolfoam specialise in concrete formwork for stormwater drainage

Secant pile walls - Polystyrene is a low cost, simple method of accurately forming guides for secant piled walls

Bolt sleeves - scuppers - Ideal for leaving a void for bolts in cast concrete - may be dissolved after use

Prestressed concrete - Polystyrene blocks are commonly used to reduce the amount of concrete poured

EPS for Pipe Insulation

If you’re after even more efficient pipe insulation, then our KoolfoamULTRA EPS is our cutting-edge product that offers even better thermal insulation than white EPS. 

The graphite particles  in expanded polystyrene (EPS) reflect and absorb heat and infra-red radiation result in up to 35% more efficient insulation than white EPS.

EPS for Pool Builders

  • Blockouts for skimmer boxes
  • Window recesses within concrete walls
  • Wet edge drains

Koolfoam polystyrene in the marine environment.

Buoyancy - In the construction of marinas and many other marine applications the buoyancy of EPS can support more weight that alternative materials
eg a cubic metre of EPS with a density of only 16kg/m3 has a buoyancy of 984kg!

Empty enclosures can be punctured and lose buoyancy but a fill of EPS prevents sinking whilst EPS stays in place.

Installation is quick and easy requiring minimal labour and therefore expense; its non-irritant, non-allergenic and odourless nature makes it superior to other insulation alternatives.

Koolfoam EPS is light, water and steam resistant, unaffected by fungi and bacteria, and will not support insect or pest life.

Flotation - Used for buoyancy in the construction of boats of all sizes

Pontoons - A cost effective flotation material in the production of pontoons - easily formed and long lasting in a marine environment
