One Way Directional Trimline Wood Vents

One Way Trimline Vents

The one directional wood vent is one of the most popular custom ordered items. It is most commonly used in wall mount applications for either supply or return air applications.

We make these wood vents as flush no frame, insert style, or flush with frame. We can also make these vents with a “hidden” or half divider which may provide a cleaner and more modern look.

These vents can be made with the louvers angling the air in either the long direction or short direction to fit your HVAC needs.

Our one directional vents come in stock sizes, or can be custom made for each customer’s job. This ensures fit will be perfect, down to the sixteenth of an inch.

One Directional Trimline Wood Vent Construction

Quality Craftsmanship helps set our woodvents apart from the competition. We proudly manufacture these in the USA.

We can make these vents for duct openings up to 48″ long. If you need bigger, we can make the vent in multiple pieces and tie them together as seamlessly as possible.

Long Way Directional Vents are Made Differently depending on Floor or Wall Application

Floor Application

For all vents with a duct opening greater than 10″, there is a vertical divider for every 6″ of duct opening (approximately, the vent will be broken into even sections
The Vertical Divider MUST COME THROUGH TO THE FACE OF THE WOOD VENT
Vertical Divider is 1″ wide
Vertical Divider is Tongue and Groove for strength
Openings are 5/16″ wide. Louvers are 1/4″ wide. This may be adjusted slightly depending on duct size.

Wall Application

For all vents with a duct opening greater than 12″, Vertical dividers will be placed in equal sections. The maximum length between dividers is 12″.
Vertical dividers can be to the face of the wood vent or “hidden/recessed”
Hidden dividers come half way up the louvers. They are 3/8″ wide.
Openings are 5/16″ wide. Louvers are 1/4″ wide. This may be adjusted slightly depending on duct size.

Both of the above wood vents are for a 4 x 24 duct opening.

The top vent has two 12″ sections of louver with a divider coming to the face.

The bottom vent has four 6″ sections of louver with the divider coming to the face.

What style of vent works best for your application?

Floor Application

Insert Style: Easiest to install. The flange provides cover for any rough cut openings

Flush No Frame: Very clean, modern look. Will need clean cuts to install. Not always recommended for floor as expansion and contraction may make removal for cleaning difficult.

Flush With Frame: Great for floor application. We recommend having grills onsite prior to floor install so everything can be snugged up nicely. Frame will take the expansion and contraction of the floors, making the gut section easier to remove for duct cleaning in the future.

Wall Application

Insert Style: Easiest to install. The flange provides cover for any rough cut openings as well as a place to mount screws.

Flush No Frame: Very clean, modern look. Install requires a bit more skill. Will either need to “frame out” opening from inside to provide nailing surface, secure J-Bead to vent for drywall installation, or hold in place with molding. Magnets are another option.

Flush With Frame: Not recommended for wall application, though we can make a “gut only” to custom fit any rabbet cuts you may have made.

Ceiling Application

Insert Style: Easiest to install. The flange provides cover for any rough cut openings as well as a place to mount screws.

Flush With Frame: Not recommended for ceiling application, though we can make a “gut only” to custom fit any rabbet cuts you may have made.

Custom Options for Trimline One Directional Wood Vents

Options for all Trimline Wood Vents Regardless of Style

Duct Opening: This is the most common part of the wood vent that we make changes to. The smallest duct opening we can do is 2″, and the largest for one vent we can do is 48″. Need bigger? We can make the vent in multiple pieces. We can handle measurements down to 1/16 of an inch.

Divider Thickness: Our standard divider is 1″ thick. We can do custom widths to hide things behind the vent as well.

Louver Thickness and Opening Measurements: In certain applications we can change thevsize of our louvers and the width of our openings.

Insert/Self Rimming

Flange Size: Our standard size flange is 3/4″. Sometimes you need a larger flange to make installation easier. Sometimes you need a smaller flange to fit a tight space. We do this all the time!

Flange Removal: We can also cut a flange or two off in order to fit into tighter spaces.

Neck Removal: Sometimes the “neck” on the vent can impede installation. We can sand that off no problem.

Squared Off Shoulder: Our standard vents are rounded over, but we can make them with a “square shoulder” no problem.

Flush No Frame

Vent Thickness: Our standard thickness for flush mount wood vents is 3/4″. We can go thicker or thinner depending on your needs. This is most commonly done for engineered floors, or floors that have been sanded in the past. 3/8″ thick is the thinnest we can go.

Rail Width: We can increase or decrease the width of the “rail” (border) in order to fit your opening needs.
