Thank you for your review. The insulation blankets are a wonderful way to keep smoking year round. The foil backed heat-resistant fabric reflects the heat back to the grill and should not be used in temperatures over32 degrees or when cooking on higher temps like 350 and above. Using the grill when it is set (says) 500 will damage the paint, the blanket itself, and can cause fires. You can learn more about the insulation blankets in the accessories section of Traeger support page. If you are experiencing any defects in the blanket, please call/chat with one of our support agents.
