Rigid polystyrene foam is the most common insulating material in the building industry.
It is suitable for almost all types of insulation work, whether for renovation or for new buildings.
Its thermal insulating power, measured by the coefficient of thermal conductivity, expressed in W/mh ° C, oscillates between 0.027 and 0.031, and is normally calculated as 0.030.
The specific weight is the first of the physical characteristics of the EPS to be considered because it varies from 10 to over 40kg / mc.
It is breathable and water vapour permeable (a factor that prevents the formation of mould), waterproof and is not subject to sublimation.
It is compatible with the majority of building materials which make it extremely versatile.
Another important aspect is the fact that EPS is non-toxic and therefore poses no risks for the environment or for groundwater.
It is important to highlight that the EPS used must meet the requirements defined by regulation EN13164 and its relative EC mark.
