Thermocol : It is the trade name of a very light and cellular plastic material. Initially it is obtained in liquid form and then molded into desired forms. it is an excellent insulating material of heat, sound and electricity.


It is very light, strong and durable.

It resists dampness.

Its compressive strength is 117 to 144 kg/cm2.

It can be manufactured in any color, though it is mostly white in color.

It is very soft, can be easily swan, cut, broken and scratched with nails.


It is used for heat and sound insulation in refrigeration and air conditioning buildings.

It is used in acoustic treatment and lining of ceiling and walls.

Thermocol is available in slabs 50×50, 60×60, 100×100, 50×100 cm and 15 to 25 mm thick.

Thermocol is another name for Polystyrene, it’s a synthetic aromatic (benzene derivative) polymer made from the monomer styrene (a monomer is a molecule that may bind chemically to other molecules to form a polymer. Hence the name Polystyrene). It can be either solid, or foam like (styrofoam!), and because of it’s resilience is often used in protective packaging – CD and DVD cases, and styrofoam peanuts.
It is most assuredly not environmentally friendly, it doesn’t degrade for hundreds of years, and is resistant to photolysis.
