Tunnel Doors

The laminated, composite door panel of 1.5-inch (38-mm) thick extruded foam insulation is sandwiched between thick, pebbled fiberglass-reinforced plastic.Structure of door provides greater rigidity and dent resistance.Wall-mounted, continuous P-shape seal is more forgiving of house imperfections for a tighter seal when door is closed and does not affect airflow when door is open.Complete door assembly is pest- and corrosion-resistant (composite door, stainless steel hinges and nylon/galvanized hardware).Modular panel design allows maximum door size flexibility to match house sidewall openings.
