Hello greatgrannan! I apologize for any inconvenience or dissatisfaction that this may have caused you. Yes, you are correct the Thermo-Plastic Fasade panels do have a heat tolerance up to 140 degrees. Even though the backsplash panels are fire-retardant, they can be deformed by excessive heat. The panels can be installed above or behind most stoves, toasters, toaster ovens, crock pots and coffee makers as long as the appliances are not pushed up against the Fasade backsplash panels. We recommend allowing a few inches (3-4) of space between the appliances and your decorative backsplash. This will insure that the beauty of the decorative panels will last you a lifetime and protect against any damage from radiant heat coming from the appliances. Please contact customer care for any further questions or troubleshooting advice at 800.434.3750. Thank you!
