Tunnel Doors

Chore-Time’s tunnel doors tumble air for better mixing over curtian or double door design tunnel inlets. The composite door and stainless steel hinges are corrosion and pest resistant.


  • Laminated, composite door panels of 1.5-inch (38-mm) thick extruded foam insulation, sandwiched between thick pebbled fiberglass-reinforced plastic.
  • Wall-mounted, continuous "P"-shape seal does not affect airflow when door is open, and is more forgiving of house imperfections for a tighter seal when door is closed.


  • Up to five-foot door heights available to match typical tunnel house openings for retrofit or new construction.
  • Pre-assembled door available for steel truss buildings or knee-brace applications
