Cornice Window Treatments

Cornice window treatments are the easiest way to spruce up any interior decor whether at home or the office and can add an extravagant touch to ordinary curtains or drapes. Window cornices can amplify even the simplest of themes and once you have the right tools it’s relatively easy. Pattern paper, wood, screws, L shaped and mounting wall brackets, tape measure, level, pencil and the appropriate saw and sanding tool are basic.

How to Install Cornice Window Treatments

First, choose the window (s) to be corniced, be sure to make all matching cornices at the same time to ensure that the patterns are right. Measuring the chosen window to determine the area to be covered and how high the cornice should be is an important step. Avoid making estimations at all cost. Since cornices will be attached to the wall, give a 2 inch allowance widthwise on each side. This will give each cornice enough room to be attached without being shortened.

Once an appropriate size is determined, a real-sized paper pattern should be made. An idea of what the final window cornice will look like can be ascertained by holding up the pattern to the designated window. If the size doesn’t match, then remeasure the window and make a different pattern. Repeat the steps until the correct size (and desired pattern) is reached so that the pattern transferred to the wood is the pattern you actually want to cut. Once measurements are accurate; trace pattern onto the boards and start cutting. Be sure to measure cornice board before cutting wood since this is irreversible.

A skill or electric saw should used. Do not neglect tool guidelines and be use to use the necessary protective gears. Always smooth edges by sanding them, both for a better finishing look as well as to avoid injuries that can occur from little pieces of wood jotting out. Sidepieces for wall attachment should also be cut. These are to be the same height as the window cornice but just 3 to 4 inches in width.

The window cornice can now be covered with the desired fabric; a thin foam layer can be placed under the fabric for a better look. Be sure to apply glue to the ‘wrong’ side of the fabric so that it is turned right-side up when you are finished. Smooth the fabric removing any lumps or air pockets, folded under edges can be secured using a staple gun. Extra fabric can be used to cover any raw edges. Note that paint or stain can be used instead, make sure that cornice is properly sanded since paint, stain or varnish can magnify roughness. Do not move the cornice until completely dry.

To assemble, use small screws capable of penetrating board but without coming all the way through and “L” brackets to attach sidepieces to the cornice. Each side should have one bracket to the top and one to the bottom.

To install, attach your window cornice to the appropriate position on wall around its designated window using screws and mounting wall brackets. Attaching it to the wall studs will provide added support. Before fastening the brackets tightly make sure the cornice is level. A Level will make this easy.
