Window Shade & Treatment Glossary

If you’re unfamiliar with the window treatment industry and need some help breaking down the terminology, that’s what we’re here for! What we’ve done is put together a list of definitions that will help you pick our your next arch, cell or skylight shades.

Arch Windows:It's just what it sounds like, it’s a window that has a round portion then a flat bottom. Often times homeowners will call these “half-moon” windows.

Awning Windows: Hinged at the top and they can swing outward. They are typically rectangular and are wider than they are tall.

Balcony Skylight Shade: Designed by Comfortex, they are a skylight shade system that used cellular fabric. This shade has a reinforced retainer track on both sides of the shade, the tension is also adjustable providing the end user optimal functionality.

Bay Window: Is a window that will extend outward from a main wall. It forms a protrusion from the exterior wall.

Black Out: For complete light control, this fabric is often chosen as it “blacks out” the light from the outside world.

Blinds: Known as “hard” window treatments, they have slats that move around to control the light. Compared to shades, blinds do not hold as many energy efficient properties.

Bow Window: Like a bay window, but curved.

Bracket Hardware (Mounting): This is the hardware that is used to hold the shade inside the window’s frame. The brackets at are comprised of metal and can be used for both inside and outside mounted shades.

Casement Window: Is a window that uses a crank for it to open outward.

Cell Size: How large the size of the honeycomb is on cellular shades. This will determine the appearance of the shade and how it folds onto the front.

Cellular: These are our favorite shade type. They are called “cell” shades because they have chambers that created by the fabric attached to itself.

Child Safe: Both cordless and motorized are the only “child safe” window treatments available to parents. You can also purchase cord cleats and tensioners to modify your existing treatments to make them more child safe.

Color Strip: This is a small strip of metal that acts as an insert in the headrail for cord loop, cordless and motorized shades to allow it to match the color of the shade’s fabric.

Cord Cleat: This piece of hardware is used with most standard shades. It will help you wrap the cord around it, to make sure it cannot harm young children.

Cord Loop & Continuous Cord Loop: A cord that’s fused into a circle. Think of it as a bicycle chain for hand over hand operation. It works on our Omnirise, Smoothy and Continuous Cord window shades.

Cord Tensioner: A feature that holds up a cord loop against a wall or window frame. The operation of this shade will help keep both children and pets from entanglement.

Cordless:A type of shade with no strings, hence the name “cordless.” This will allow you to open and raise your shade by gently pressing on the shade, it’s also the most child safe treatment that’s available.

Deductions: Both the rails and the fabric will be cut smaller and narrower for shades that inside mounted and have sidetracks. The reason this is done is it allows the entire unit to fit within the window’s frame. If your order from, don’t worry, we take all of this into account for you!

Double Cell: Dual honeycomb configuration that has two diamond-shaped cells also called “chambers.”

Duofold: Please see the description for Top Down Bottom Up. Eyebrow Window: Windows that have been hinged (not always) at the bottom that has a semi-circular top.

Pleated Sheet: Fabric for a shade type that’s shaped like a zigzag when you look at it from the sides. They are a bit different from cellular and honeycomb shades because they do not have chambers.

Raillroading: It’s when you use the fabric horizontally instead of vertically. Often times this is used for roller shades to get them wider.

Roller Shades: Vinly shades that are attached to tubes. They can come with spring rollers and also may be motorized.

Roman Shades: Shades that are drawn up from the bottom. When they raise, they create horizontal folds, they also lay flat when they cover the window.
