Do not infer performance from application method alone; review test and repair documents for the exact construction.
Do not choose PUR foam or board by material name alone. Request the full-body construction, joint and corner details, verified insulation test and repair method for the offered model. Compare data produced under equivalent conditions and criteria. An infrared surface reading alone does not prove insulation performance inside.
Foaming PUR in place and fitting boards are different manufacturing methods; the method alone does not prove better insulation.
For each candidate model, request body cross-section, lid and corner details, test conditions and report. Compare material thickness, joints and the complete container on the same scope.
Compare which parts can be repaired and how. Do not infer hold time or classification from a single surface-temperature reading.
