A window cornice is a 3-sided box that frames the top of a window. A cornice generally covers—and extends out over—curtain rods, the top portion of blinds, and window casings. It can be as tall as you treatment to make it, uncomplicated or fancy.

A window cornice is generally strong, like these built from wooden in this tutorial, whilst a window valance is historically built from fabric and far more like a small curtain at the top of the window.

How to Construct a Do it yourself Wooden Window Cornice

Please hold in intellect that all of these wooden proportions and trim parts are unique to my cornices—-you may well want to do anything distinct.

Stage one: Program & Measure

Program the glance of your cornice. Take into consideration:

  • What trim, if any, do you want to use?
  • Will you stain it or paint it?
  • How tall and vast do you want it to be?
  • How much space do you have earlier mentioned and on the sides of the window to get the job done with?

Measure your window from the outdoors edge of the window casing on just one side to the outdoors edge of the window casing on the reverse side. Do not measure just the window by alone. Involve the casings!

Your cornice will cling down over the window and the casings. I selected to add 4″ (that’s 2″ for each individual side of the window) to my window measurements. Why? To allow for the width of the edge of the cornice and for a small space between the window casing and the cornice.

Also measure out from the wall to determine how deep your cornice demands to be. Will the cornice cling over a curtain rod or blinds? The cornice box demands to be deep enough to prolong out over any obstacles—-the window casing, blinds, or curtains.

Insert at minimum a one/2″ or so to your depth measurement so you won’t have to stress about your cornice scraping up from your window treatment plans soon after it’s put in.

Centered on the clearance you have between the ceiling and your window, as nicely as your personalized choice, determine how tall you want your cornice to be.

Acquire your resources and make a sketch of your proportions.

Stage 2: Lower the Wooden Cornice Items & Crown Molding

I minimize all the parts for my cornice 1st.

I minimize my 1″ x 8″ common board to size and minimize equally of the small sides at a beveled forty five-diploma angle employing a miter observed. This piece is the front of your cornice box.

For the top and side parts of my cornice box, I necessary a shallower width of board, so I ripped my 1″ x 6″ common board down to 1″ x 5″ (a non-standard size not obtainable at my area lumber yard) employing a desk observed. I then minimize the top and side parts of my cornice box from the 1″ x 5″ board.

For the side parts, I made use of my miter observed to minimize forty five-diploma angles on just one of the extended edges.

I minimize my crown molding and ogee trim, equally the front and side parts, mitered to meet flush at the corners of the cornice box.

See this publish for strategies and methods to enable you find out how to minimize crown molding and other trim — and constantly try to remember to observe, observe, observe on some economical molding or scraps right until you’re self-assured with your cuts. 

For the ogee trim, set your table to forty five-degrees. Go away your blade on center at -degrees.

For the crown molding, you’ll need to have to set the angles on your blade and desk in accordance to the spring angle of the crown molding you’re employing. I made use of just about the most fundamental and commonly obtainable crown molding there is (spring angle: 53/37). I set my miter (angle on desk) to 31.5-degrees and my bevel (tilt of blade) to 34-degrees.

The most significant piece of crown molding, jogging together the top of the cornice box, has 2 outdoors corners.

The left-hand mitered outdoors corner is minimize by positioning the crown to the correct of the blade. The top edge of the crown rests up from the fence. The miter angle on the desk of your miter observed is set to the correct of center.

You will also minimize the correct-hand side piece of crown this way. The edge of the side piece of crown that meets the front piece of crown will be minimize at an angle. The other side will be flush from the wall, so it’s a straight-edge minimize.

When chopping crown, I constantly add a 50 %-inch or a small far more to the whole size I measured right before chopping. I’ll do a check fit soon after earning my 1st minimize and then trim a small far more off if I need to have to, but with crown, at the time you minimize it far too small, you’re out of luck! So I’m constantly really, really cautious and just take my time to be positive to get it correct. Hold in intellect, far too, that crown has to prolong a little bit earlier the size of your cornice box. If the minimize edge of the crown lines up specifically with the edge of the cornice box, there won’t be enough of an edge left on the crown to meet up with the edge of the side piece of crown, which you’ll want it to do in order to get a neat corner.

Stage 3: Assemble the Wooden Cornice

I drilled holes employing my Kreg Jig together the top, inside of edges of my front box piece and my 2 side box parts. (If you never possess a Kreg Jig, you can join your box jointly by 1st gluing with wooden glue and then employing ending nails or a nail gun.)

I made use of wooden glue to join the mitered edges of my side box parts and my front box piece and clamped it all to dry. Then, I made use of my eighteen-gauge nail gun to enhance the bond by nailing the parts jointly (you could also use a hammer and ending nails, if you never have a nail gun).

Stage 4: Attach Cornice Trim

I connected the ogee trim flush to the base edge of my cornice box with my eighteen-gauge nail gun (you can also use ending nails and a hammer). You can glue 1st, far too, if you’d like to.

Right before attaching any trim, nevertheless, check the fit of your corner parts to make positive they fit jointly correctly. how to build a DIY wood window cornice, solid wood window valance box

Make measured marks all together the size of your box where you want your crown molding to be. Then, use a stage or other straight edge to connect the marks so you have a line together which to line up the base edge of your crown molding—you want it to be stage. Nail together the base edge of your crown to attach it to your cornice box. It can be any place on the box body you pick out for it to be—-flush with the top edge of the box or someplace farther down the box. I selected to have a 5-one/2″ gap between the top of my ogee trim and the base of my crown molding.

You can constantly add a shelf to the top of the cornice box, which would give the crown anything to attach to (like it would if it ended up remaining equipped together a wall and ceiling), but since on this cornice, I selected not to add a shelf, I had to glue the corner crown parts to the center crown piece to attach them.

Use painter’s tape to secure the connection right until the glue dries. Attach the base of the side parts of crown with nails together the base edge, just as you did with the front piece of crown.

I would advise from making an attempt to nail the top piece of the side crown to the top piece of the front crown, as you’ll risk splitting the crown.

Right after the wooden filler and caulk have dried, do a mild sanding to ensure a sleek completed area. Wipe absent all dust and debris.

I made use of just one coat of primer and two coats of paint, permitting all the things dry carefully between coats.

Keep in mind to paint the underside of your cornice box, far too, as it will be noticeable if a person is standing near to, or under, the window.

If the top of your cornice box will be noticeable, be positive to paint the top, far too, but most of the time, a cornice box will be so near to the ceiling that no just one will be ready to see the top of it.

How to Cling a Wooden Window Cornice

Lower a 1″ x 2″ strip of wooden just shorter than the entire size of your done cornice box.

Mount it to the wall earlier mentioned the window where you’ll be hanging the cornice, employing a stage and 2″ wooden screws. Be positive to attach to studs and not just dry wall.

Hold in intellect how significantly down over your window you want your cornice to hang—-that will determine where on the wall you put in the 1″ x 2″ strip of wooden (your cornice box will ‘hang’ on this strip of wooden).

You will attach your window cornice box by ‘hanging’ it on, and screwing it in to, your 1″ x 2″ strip, which you have mounted to the wall earlier mentioned your window. It won’t be secure enough to just ‘hang’ the cornice box on the 1″ x 2″ strip. You need to have to screw down as a result of the top of the cornice box, in to the 1″ x 2″ strip at normal intervals together the size of the cornice box.

To make the position less complicated, I screwed my 2″ wooden screws partly in to the top of my cornice box right before hanging it, so that I’d have much less screwing to do soon after putting the cornice box in position over the window. Be conscious in the placement of your screws. You never want them so near to the edge that the wooden splits, as a result compromising the attachment. Neither do you never want them so significantly absent from the edge that they won’t screw down in to the top of your wall-mounted 1″ x 2″ strip.
