XPS Quality

Conformité Européenne

Exiba manufacturers provide a Declaration of Performance (DoP) for their products which allow them to affix the CE marking, thereby indicating that they take responsibility for the conformity of the XPS product with its DoP, as well as for the compliance with all applicable requirements of the EU 305/2011 Construction Products Regulation (CPR).
