Nelissen Bricks gives a ten year warranty on the ISO•Façade system and all individual materials accompanying the package, insofar as it has been processed in accordance with the requirements and qualitative and professional processing, based on the Iso-Façade system guidelines.

The aesthetic facade quality - such as flatness and rigidity, that are related to the execution - are excluded from the warranty. When treatment and/or an impregnating layer is applied to the ceramic finishing, no use can be made of the warranty.
