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 at least 8 times better than a curtain during winter.
During tunnel-assist mode, cold air is directed away from the birds until it has mixed with house air.
Innovative Design
Laminated, composite door panel.
Structure provides greater rigidity and dent resistance.
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.
Modular panel design allows maximum flexibility in door size to match house sidewall openings.
