EXO 3-Rib - EPS is the three-rib roof panel of the EXO series with an expanded polystyrene core. It is the most economical option in the series.
The thermal conductivity of the EPS core is 0.038 W/mK: the same insulation value requires more than twice the thickness compared with a panel with a polyurethane core. Since the thickness is limited to between 30 and 60 mm, this difference cannot be closed; the panel is suitable for unheated or partially heated buildings.
There is no published EN 13501 fire class for this product and the class field has been left blank. On a project where fire performance is decisive, a panel with an EPS core is not considered.
