The material is obtained by means of extrusion. It has good fire behaviour. XPS sheets are highly resistant to water absorption and have nil capillarity, they are very resistant to the diffusion of water steam and are not affected by repeated cycles of freezing-defrosting. Mould does not form on them and they do not have any nutritional value for insects and rodents. They can be mechanically and chemically recycled.
It can be supplied in sheets. It can also be supplied in cut, copied or milled pieces.
