Diversified Tunnel Shutters

Tunnel Shutters® are the optimal solution for allowing smooth laminar airflow into the house with no door turbulence—aiding with ventilation while also preventing air leaking for significant energy savings.

Diversified has simplified tunnel ventilation and extended product longevity with our Tunnel Shutters. Rather than fighting against the negative static pressure of a house or barn, Tunnel Shutters utilize the negative pressure to create a tight seal. Plus, the 2-inch-thick coated-galvanized steel shutters are insulated with foam-filled expanded polystyrene to deliver an R9 insulation value that drastically reduces energy costs.

The Tunnel Shutter’s maintenance-free rack and pinion drive system eliminates the need for cord or cable adjustments, and the innovative design allows the shutters to open to the outside–eliminating operating issues common with curtain and tunnel door systems.
