This document provides product category rules (c-PCR), that are complementary to EN 15804:2012+A2:2019, for Type III environmental declarations for sandwich panels within the scope of prEN 14509-1:2025 and prEN 14509-2:2025, which are used for non-structural and structural purposes in building envelopes and for sandwich panels with perforated faces and for sandwich panels with core materials others than defined in prEN 14509-1:2025 and prEN 14509-2:2025.
Manufactured on industrial plant, double skin metal faced insulating sandwich panels are designed to be laid with overlapping edges in the following applications:
