Casement windows, or those windows with crank handles that swing open, rather than slide up, are known for their clean lines, abundant light, and excellent ventilation. But if you’ve ever tried to install shades on them, you know there’s one challenge: the crank handle. Standard handles can protrude far enough to interfere with the operation of your shade—especially with a snug inside mount.
This guide will show you how to choose cellular shades for casement windows that fit perfectly, avoid interference, and enhance your window’s insulation and style.

Understanding Casement Window Hardware
Most casement windows have a crank handle or T-handle to open and close the sash. The handle location and depth can affect whether your cellular shades can operate smoothly.
-
Standard Crank Handle (Figure 1): Common on many casement windows, this handle can protrude several inches.
-
Slim Crank Handle (Figure 2): More compact, allowing more clearance between the handle and shade.
-
T-Handle (Figure 3): Low-profile design, often the easiest option for fitting inside-mounted shades.
Inside Mount vs. Outside Mount Cellular Shades
When installing shades on casement windows, you’ll typically choose between an inside mount and an outside mount:
-
Inside Mount: Offers a sleek, built-in look but requires precise measuring to avoid handle interference. Slim or T-handles are often necessary.
-
Outside Mount: Installs on the wall or trim above the window, clearing any handles completely. This option can also make the window appear larger.

What are the benefits of cellular shades for casement windows?

Excellent Insulation: Honeycomb cells trap air, improving energy efficiency year-round.
-
Light Control Options: Choose from light filtering to blackout fabrics depending on your needs.

Custom Fit: Can be tailored to your exact window size, including unique handle clearances.

Pro Tip: Measure for Handle Clearance: Before ordering, measure from the deepest part of your window recess to the tip of the handle. Compare this to the manufacturer’s required clearance for inside mounts. If space is too tight, consider switching to a slim or T-handle—or opt for an outside mount for guaranteed clearance.
