Tunnel Shutters®

Tunnel Air Technology For the 21st Century


Tunnel Shutters® have an air tight pressure seal and utilize the  negative air pressure within the house as opposed to Doors that constantly fight against the static pressure. When closed the Shutters create a 2 inch thick insulated solid wall! 

With Tunnel Shutters®, the result is an air tight House or Barn that saves significant heating costs in the winter and increases the efficiency of the fans throughout the year by improving air flow characteristics and limiting fan usage with Sectional Vent Assisting.

Also, the modular Tunnel Shutters® Panels are fully insulated providing an insulating “R” value of R-9, which is approximately 9 times that of Curtains and higher than most Door products.
