Gable Vents

You build your louvered gable vent online and we ship it to you.

First, choose your louvered gable vent grade.

The Signature Series gable vents have a 4 fold louver to make the louver the strongest .019 aluminum louvered gable vent on the market.  The front of the louver has 4 folds and the back of the louver is double hemmed.  The Signature Series does cost more, but it is a much better product and has twice the aluminum in the gable vent as most standard aluminum gable vents.  These gable vents also have a triple layer vent wall and the louvers are mounted and wrapped on a rail.The Contractor Grade gable vents are a cheaper and more economical choice if you need a small cheap gable vent.  These have only one hem on the front of the louver and no hem on the back.   Louvered vents made with the louvers butt cut and pop riveted into a track can drop if the pop rivet ever turns loose.  By knotching the end of the louver and wrapping it around a rail, the louver locks onto the rail and gets a pop rivet for good measure.  The rail and pop rivet, along with the end of the louver, are then covered with an under cap.  The under cap is then covered with an outer cap on the gable end vent.  Once complete, the entire end vent is sandwiched in so the louvers will never come loose and the vent wall is thicker and stronger.When calculating your gable vent net free air, do not ask us how to do this.  And do not trust any website to tell you how to caculate your needed net free air.  There are too many variables we can not see in your attic and they can't see, either.  Call a professional to actually look at your attic area to see your attic configuration and any obstructions that may prevent proper venting.  Our listed gable vents are computer calculated to the nearest approximate square inch of net free air.  The options you choose for your gable end vent may vary this number slightly.
