    Q:What vent do you recommend on the opposite gable since it can't open or close by itself?
    by|Apr 1, 2024
    1 Answer
    Answer This Question

    A:  If using the Automatic Shutter Gable Louver Vent with a fan, you must determine how much intake the fan requires. Once this is done you will need to determine and match the amount of intake from the soffits or the opposite gable and use the size(s) required.

          Corners were not sealed, allowing for water to enter the wall. Product has rivets as hinge pins, instead of rod all the way across the flaps, to hold them in place. One flap wasn't rolled all the way and I had to finish the bend. Entire shutter flexes very easily. No weather stripping on backing,to seal out water. Poorly constructed. Would not buy again.

          Shutter works fine, when attic fan starts, louvers open and heat is reduced. Would have liked it to have a bug screen but I took a screen off an old window and five minutes later I was no longer worried about bugs getting in. If I need another, I know where to get them, thanks.

          Rather Flimsy Construction
          The shutter louvers are made of a lightweight aluminum that is very easy to bend. I had to pop one of the louvers back in place. I went ahead and installed it anyhow. The directions were okay, but not very clear. It will likely work, but I sort of wish I spent the time to shop around for one that was more sturdy.

            I installed this shutter to increase the effectiveness of the thermostatically controlled gable vent fan. With the shutter installed the attic seems to be getting better airflow. My overall rating is "average" because the shutter has no insect screening. The shutters have weather seals on the bottom edges; but its obvious bugs or birds could find a way in or around. I fabricated a screen box which mounts on the outside. The screen cleared the shutters with the fan running; but apparently wind gusts caused the shutter to open a bit wider and the shutters hang on the screen. I'll have to make the screen box about an inch deeper and everything should be good. Be advised: Look at the instructions on the back of the box. There will be some framing involved to install this product.

            Great For Another Use, Too
            We recently removed a low ceiling on my porch and wanted a finished look for the newly vaulted space inside. We had gable vents on the outside but wanted a great looking vent on the inside as well. The 20 inch Gable Mount fit the bill because the louvers are joined and operate together. This way we could simply prop them open in the summer and then close them in the winter. Perfect!

            Great product...some concern
            This is a great shutter for the money and it was easy to install; just use the template provided. If you're using a saws-all instead of a jigsaw you may want to add 1/4" to the all four sides. Once installed, the shutter performed flawlessly. I had to build the 20 x 20 inside frame laying flat instead of laying on edge, (as pictured in instructions), because I was installing on T1-11. But the frame, (either way), is a necessary step in order to have a solid back to screw louver on to; plus it helps to keep out roaches. Regarding the shutter and its design to open and self-close upon the outflow air from the fan, I'm concerned that a sudden updraft from a rain storm could cause it to open (I live in central Florida) but this is only a concern at this point and it has not happened. In the event of an approaching hurricane, I would suggest purchasing or having a custom built waterproof and wind resistant enclosure (on hand) to cover the shutter completely.

            Excellent Works Perfectly Looks Great!
            I actually had someone install this for me because I am disabled but it works perfectly and looks fantastic and I believe is well made.
