About Epsole





1.What is expanded polystyrene (EPS)?

Expanded polystyrene is an organic material manufactured from crude oil by-products. The manufacturing process consists of the expansion of polystyrene beads in a mould, which contains an expanding agent, pentane. When submitted to water vapour, the beads expand until they completely fill the mould. During the expansion process, the expanding agent dissipates and air is introduced to the cell structure. The final product is a rigid insulation comprised of a closed cell structure consisting of 98% air. 

2.Where can expanded polystyrene be used?
Expanded polystyrene, commonly known as EPS, made its mark as an insulation material in the 1950s. The variety of mould shapes and the possibility of producing at different densities has allowed the expanded polystyrene industry to meet almost any need for insulation, packaging and manufactured product components. 

3.Why use expanded polystyrene?
Expanded polystyrene demonstrates the properties of stability, durability and moisture resistance. Its low price, versatility, easy installation and insulation value/price ratio make it an insulation of choice for architects, estimators and contractors.

4.Is expanded polystyrene dangerous for the environment? 
Expanded polystyrene emits no ozone-damaging gas. This material is recyclable and reusable and retains its insulating value over the long term. To learn more, check out the Environment section.
