EPS - Expander Polystyrene
Expanded polystyrene (EPS) is produced from a mixture of polystyrene, which is a thermoplastic material manufactured from a petroleum product, and a gaseous, blowing agent pentane. With the help of pentane and through the use of steam, polystyrene is expanded to turn into a foam and takes the shape of the form used. Through this process, pentane replaces inside air. The voids filled with trapped air, gives EPS board a low thermal conductivity and therefore makes it a good thermal insulation material.Among thermal insulation materials used in construction, EPS is the most lightweight and economical material.
