No Flange:
This
option has no nailing flange or fin to restrict the vent from sliding
into the opening. When placing a louver vent in a brick hole or
existing window frame, a flange may be more of a hindrance than a help.
Since this vent option provides none of these, it does not require you
to cut off or have to trim the nail fin. Worried about mounting?
Don't. All Onyx Xteriors vents are triple walled (minimum) for the
optional side wall screw/fastener placement. This means you can apply
screws through the side of the vent behind the louver face to hide the
fasteners. Careful not to over tighten as aluminum vents need to shift
and move slightly as wood expands and contracts with weather.
Front Flange:
Focus
only on the vent size you need. Then imagine the face flange
protruding 1 1/2" beyond the vent all the way around to cover the rough
opening edges and assist in protecting the gable wall from leaks. This
flange also acts as a stop for the vent to insert into the opening and
the front nail fin will butt right up to the wall face on the outside.
Don't want to dent up the flange with nails since the face may be
visible after the install? We've got you covered. Align the vent where
you want it and place a few screws behind the front of the louvers
right through the side wall of the vent. These are tough gable vents.
Back Flange:
Stucco
and brick applications have benefited from these attic vents for many
years. With an inch and a half nail fin around the rear of the vent, it
is as simple as place the vent, screw or nail the flange to the wall
and done. Then just apply the cladding to the wall round the vent.
Another advantage is if choosing a 4" or 6" depth, you get to choose the
placement of the back flange on the vent. This way, if a deeper vent
is needed for the area but the flange needs to be before the back of the
vent, it can. Just choose your depth.
J-Channel Flange:
Facing
the vent with a 1 1/2" front flange, then a 1" deep pocket and a 2 1/2"
back flange creates a J channel pocket for vinyl siding, Hardie plank
and many other house coverings. If a deeper pocket is needed than the
standard 1", let us know in the comments box when ordering. Pre
insulated siding for example needs a 1 1/4" J pocket for proper
movement.
Round gable vents are just nice to look at when you have too many
straight lines on a home. Most homes seem to be built on square boxes
with triangles on top. The curvature of a round vent can break up the
monotony and add comfort to the style of the home.
