With up to 3.5x higher energy efficiency than single-flap doors, it helps minimize heat loss in winter and heat gain in hot weather. The snap-on weather shield adds insulation for severe conditions such as blizzards, tornadoes, or hurricanes, and the white plastic frame is built to withstand daily use. Installation is straightforward in most doors 1.5" to 2" thick, and the included sizing chart guides you to the right size for pets up to 40 pounds.
