DESCRIPTION OF PROPERTIES

excel in all durability factors.

the reusability of insulation is dependent on system design. The design should: prohibit insulation attachment with adhesive and promote drying of insulation

It is made from fossil fuel and HCFC-142b.

Polystyrene is produce from gas and petroleum derived that are finite resources

Recycled plastic resin can be use to produce XPS, until a 50%, but very few manufacturer produce this material.

 PROS

Polystyrene is thermoplastic so can be melted and reformed into othe rproducts with a minimal chemical modification, that make easy the recyclage, but the dust and dirt limite the recyclage possibility.

 CONS

Threaten the environment.

It is not always free of CFCs and HCFCs.

The manufacture process collaborate at the ozone depletion and global warming.

It is identified by EPA as a possible carcinogen, mutagen, chronic toxin, and environmental toxin. Further, it is produced from benzene, another chemical with both environmental and health concerns

XPS is blowing with HCFC agent that is an ozone layer damage product.
