Cornice Boards

Cornice Boards

What is a cornice board?

It's a decorative board that covers the tops of windows where the blinds are attached to the wall; it is literally window dressing.

What are the measurements listed in creating a cornice board: width, height, and return?

The width is the outside horizontal measurement - left to right or right to left. The height is the outside vertical measurement from the top to bottom or bottom to top, at the cornice's maximum point. The return is the outside depth from the cornice to the wall.

What do you mean "outside" measurement?

When we use the term "outside" measurement, we mean from tip to tip or maximum point to point. It means you want the dimension to go from X to Y exactly (to avoid getting complicated with board depths and thicknesses, doing outside measurements makes it easier on you and easier on us to know we're working within the same framework).

How wide should we make a cornice then if our window is X inches wide?

We suggest a width of at least X + 3 inches (1.5 inches per side) to allow a little bit of room for installation on each side (this assumes no molding which would need to be accounted for).

What materials are your cornices made from?

The face is made out of 1/2" Grade A1 birch plywood. The return is made of 3/4" Grade A1 birch plywood (thicker for additional strength).

Do your cornice boards have a top piece?

Yes, our cornice has a top piece that runs the length of the cornice to help support the unit between the wall and the face.

I ordered a cornice but it came in two pieces - what gives?

Due to shipping costs we may build longer cornice boards (approximately 70" in length or more) in two or more sections. We will build it in such a way that combining the sections is easy and we'll include the necessary hardware to reconnect it.

Won't the cornice be weaker if it was built in sections?

As Nietzsche once said, "That which does not kill us, makes us stronger." Maybe he wasn't talking about cornice boards at the time, but who knows? But no, no your cornice will not be weaker.

Will the cornice board be harder to upholster if it's been built in sections?

No.

What additional materials are included with the purchase of a cornice board?

For larger cornice boards that were built in multiple sections we will also include a bag of finishing nails and a small bottle of wood glue to recombine them; instructions are not included as reassembly is intuitive. We can also include 1" x 1" "L" brackets for mounting if requested.

I want a cornice board, but a different shape. Do you do custom shapes?

Yes we can. Please send us a sketch of the cornice shape you want with exact, outside dimensions in inches (height, width, and return) to [email protected]. We'll send you back a quote.

What can be done with your cornice boards?

Use your imagination - the sky is the limit.

... No, I meant in what ways can they be finished?

Oh. You can upholster, paint, or stain the cornices.

Is there a qualitative difference between cornices meant for upholstery, painting, and staining?

Yes:

Upholstery: Sanded smooth finish. No filling of plywood edges. Will be made in separate pieces for larger cornices (70"+ in length).

Paintable: Edges are wood-puttied and entire cornice is sanded smooth. Will be made in separate pieces for larger cornices (70"+ in length) (Note: Longer cornices will still require wood putty and sanding of the seam(s), but otherwise these will be paint-ready.)

Stainable: The best-looking cornices based on grain markings. Edges are wood-puttied and entire cornice is sanded smooth (note: you will still see the plywood layers on the bottom and sides). These will include a little more packaging during shipment to help better-protect the faces of the cornice. These will be built as one seamless unit (maximum length of 96"); we highly suggest keeping these small / mid-size due to shipping costs.
