Where these two actually differ
- We flag Silicone coating degradation and volatiles, Leaching from coating into food and Off-gassing of unreacted oligomers or residual solvents on the Weber and not on the Weber.
- We flag Silicone degradation at extreme heat and Off-gassing of volatile organic compounds (VOCs) on the Weber and not on the Weber.
- The Weber is silicone mat (coating composition unspecified) where the Weber is Silicone mat or rubber composite, which is most of the difference in these two grades.
- The gap is 65 points, wide enough that this is not a close call, and the Weber is the one to buy.
- We are less certain about the Weber grade, at 35% confidence against 72%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
