Vertical Exhaust Shutter

We install these vertical exhaust shutters for Whole House Fans. We use them instead of roof ventilation in homes with tile, metal, or other exotic style roofs. This sequence of photos show the gable before the vent was installed, with the installed shutter open and with the shutter closed. These shutters open and close with a motor, which ensures that it fully opens to ventilate the fan, then closes tight to keep all precipitation out. Because of the locking action of the motor, the louvers on this shutter are completely solid and won't rattle in the wind.
