Vinyl gable vents are perfect for attic ventilation, which is an important requisite for a healthy home. Without attic exhaust vents, stale and hot air collects in the attic and is then churned around and channeled back into the house, resulting in increased energy costs. The attic also collects moisture in wet and cold weather, which can cause rot, mold, and mildew.

The best way to tackle these problems is by installing vinyl gable attic vents. These are designed to expel stale air during summer and prevent rain, snow, and wind from entering the house during winter, thereby reducing both cooling and heating costs. Given below is a step-by-step guide for installing vinyl gable vents in your attic.

Step 1—Remove Insulation

Before actually installing the vinyl gable vent, prepare the area where the installation will take place by removing any insulation that would be in the way. A utility knife may come in handy here.

Step 2—Install the Vent Frame

Use lumber boards to construct a 2x4 square frame. Place it between the studs and the gable ends. Secure the frame with screws or nails. When making the frame, factor in a 1/8-inch gap all around it. When done, drill 3/8-inch holes along the vent corners. Keep in mind that these holes will penetrate to the exterior wall of the house.

Step 3—Make an Opening

Now, approach the drilled holes from the outside. Using a pencil or a chalk line, connect all the holes and mark the outline for the vent opening. Saw through the marks and cut out the opening.

Step 4—Check Fittings

Once you have the area cut out, check if the vent fits snugly. If it is plumb, sketch out an outline for the flange. Now, using the appropriate circular saw (this will depend on the type of siding), saw through the siding. As you saw, remove any bits of remaining siding from the workspace. Once you are done, check the fitting again. Place the vent in the opening, making sure the flange is placed flat against the sheathing.

Step 5—Mount the Vent

The next step is to add flashing material around the opening. Flashing helps keep water out. Once the flashing is in place, lower the vent into the hole. Once it fits correctly, secure the vent using a set of screws.
