Just a ¼-inch gap around the unsealed sides and top of a 10’x10’ sectional door is the equivalent of a 90 square inch hole in the door and permits 328 million cubic feet of air infiltration per year. SEALEZE® brush weatherseal products effectively reduce air infiltration by as mush as 98.5%, while reducing light and odors that attract unwanted insects, rodent and other pests.
