Our Custom Faux Wood Arches match our 2" Faux Wood and Express Faux Wood colors, and are custom-made to fit your windows perfectly. No template is required for Perfect Arches (where height is exactly half the width). Eyebrow Arches (where height is less than half the width) are available without a template. Arch treatments by Just Blinds are constructed from MDF (Medium Density Fiberboard), a durable, engineered wood product that is resistant to warping, cracking, and breakage. Choose from a great selection of styles: Sunburst Arches filter soft light to enhance your arched window. Their ¼" slat openings allow approximately 15% of the sunlight into your room. A unique outside wall-mount design ensures a goof-proof easy installation, without brackets. The Blackout Arch provides complete room darkening. It may also be used above existing non-arched windows as a design element to create the illusion of an arched window where none exists. The Slatburst Arch has been engineered with 1/8" angled slat openings that filter out approximately 92% of direct sunlight. They allow a minimum amount of angled light inside the room while reflecting out most of the heat. Movable Arches allow you to control the amount of light you want to let in. Individual louvers can be rotated to the desired openness. Coordinating products: 2" Faux Wood and Express Faux Wood.
