Closed-cell ratio
An open-cell substitute changes water and vapour behaviour. Treat it as a new request, not a courtesy upgrade.

Will the quoted xps foam board insulation actually interface with the existing equipment? Insulation Foam Board Sourcing treats that as a buyer and factory confirmation, not as a site-owned pass/fail stamp.
XPS (extruded polystyrene) is not the same request as commodity PE foam or a thermoset PU pour. Write the resin the drawing expects before anyone talks about colour.
Service temperature in °F or °C decides compatibility rather than preference. A heat deflection temperature (HDT) snippet on a brochure is that factory’s claim for a named grade.
Foil, film, none, or adhesive-backed is a separate axis. Adhesive chemistry must match the substrate; this desk does not pick a tape.
If the inspector will run an ASTM method, name it. A family brochure is not a dimensional page.

Density in g/cm³ or pcf plus thickness in inches or millimetres must match the cavity. Pink colour is not a specification.
UL 94, FDA 21 CFR 177 or NSF statements apply only when the buyer named them and the file cites the quoted grade and lot.
Each reply keeps the factory name the buyer can audit. Insulation Foam Board Sourcing is not printed as the manufacturer.
Competitor part numbers are references only. A cross still has to be confirmed in writing on thickness, density and facing.
Photos and competitor numbers are starting points. Compatibility is confirmed after product, quantity, destination and sourcing requirements are reviewed with a named factory.
