Due to rising FedEx shipping costs, full carton door seal orders (less than 3 cartons ordered) will be shipped in rolled cartons. If you need material shipped in straight cartons, please contact AM Weather Guard for accurate shipping costs Pro-Ion is the ultimate material for sealing entry doors. Fen-Seal is a unique urethane foam seal that stands up to temperature and time better than other seals. Resistance to compression set, the ability of seals to spring back into shape after being squeezed repeatedly is the single most important factor in distinguishing sealing performance. All doors move. When the weather gets warm, all doors expand. When it gets cold all doors contract. Expansion puts an extreme compressive load on a door seal. Contraction can remove a door from contact with the seal. Fen-Seal door seal is designed and field proven to move with a door, through expansion and contraction. Fen-Seal will take severe compression and then rebound into its original size and shape. Fen-Seal seals have been independently tested.
