Tunnel Doors for Breeders

Chore-Time’s tunnel doors tumble air for better mixing throughout the house.

Better In-House Air Mixing

Cyclonic air movement generates desirable airflow at bird level throughout the house.
No more dead zones at side- and end-walls such as are typical of curtain sidewall or double door houses.
Insulates about eight times better than a curtain during winter (when completely closed) for reduced energy costs.
During tunnel-assist mode, cold air is directed away from the birds until it has mixed with house air.

Cost Effective and User Friendly

Laminated, composite door panels of 1.5-inch (38-mm) thick extruded foam insulation, sandwiched between thick pebbled fiberglass-reinforced plastic.
Structure provides greater rigidity and dent resistance.
Wall-mounted, continuous “P”-shape seal does not affect airflow when door is open, and is more tolerant of house imperfections for a tighter seal when door is closed.
Assembly (composite door, stainless steel hinges and nylon/galvanized hardware) is pest- and corrosion resistant.
Modular panel design allows maximum flexibility in door size to match house sidewall openings.
Pre-assembled door available for steel truss buildings or knee-brace applications.
