Baffle boards serve to increase the efficiency of your stove and protect the top of your stove from excess heat, which can cause warping. Baffle blankets sit on top of the baffle board to provide additional heat protection. The baffle is an important part of your stove, redirecting heat downward to achieve more efficient burns, and also keeps smoke from pouring out of the front of the stove when you open the doors. Baffles are subjected to incredibly high temperatures, and so they will need to be periodically replaced. Stove Parts for Less carries baffle board and blankets for a variety of stove models!
