We have an issue about how to perform an EPD project for a client.
Our client would like an EPD for their Insulated Metal Panels used for cold room system.

Is it valid an EPD only for panels used for a cold room ? Even though the final product sold to the customer is a whole cold room system including a door system (made in the same panel but incorporating the system of hinges and handles) and sometimes having windows and optional anti-fog system.
Is it more valid a EPD for the whole cold room system? Even if  that cold room system is a custom-made product.

That exist a specific PCR for insulated panels but not for cold rooms.

Thank you
