DESCRIPTION OF PROPERTIES

It is produce by expanding styrene beads using pentane gas, a hydrocarbon that contributes to localized smog production

It is made from fossil fuel and pentane.

great impact on the environment from the extraction of petroleum, via the refining process, up to and including the processing of waste

Long life expectancy, low maintenance

High embodied energy

Polystyrene insulation can be produced with a minimum of 50% recycled polystyrene content, any polystyrene can be recycled into building insulation.

 PROS

It is the only one rigid foam insulation made with neither CFCs nor HCFCs, it has one environmental drawback: pentane emission during manufacturing.New plant are reducing this emission.

EPS can be recycled for manufacturing into new styrene products.

 CONS

It required more energy for the production process than mineral wool.

The pentane emissions contribute to smog.

Fire retardant can reduce recycle opportunity.

Very high embodied energy.

 RECOMMENDED USES

avoid the use of bitumen as a means of fixing
