Corner Window Shades & Blinds

A corner window is two windows that meet, either at a solid corner post or glass to glass, and that is what makes it awkward. Each side needs its own shade, the two shades have to meet without colliding or leaving a bright slot between them, and because the glass faces two directions the light changes from one side to the other through the day. Everything here is made to the widths you measure, one shade per side, and shipped direct to you.

Which shades and blinds suit a corner window

Roller shades are the usual answer, because a flat fabric that rolls up into a compact cassette is the easiest thing to butt neatly against a second shade. Light filtering roller suits a living room or kitchen corner, and blackout roller a bedroom corner.

Solar shades suit a corner that takes sun on one side in the morning and the other in the afternoon. Our sunscreen fabrics come in 1, 3, 5 and 10 percent openness, blocking roughly 80, 70, 60 and 50 percent of light, so you can choose a tighter screen for the hotter side and an opener one for the other while keeping the view on both. Zebra shades work well where the corner is the main view in the room, since the alternating sheer and solid bands slide past each other and let you set privacy and view on each side on its own.

Light filtering and blackout cellular shades are worth considering where the corner is costing you heat, since a corner window puts glass on two outside walls.

Cassette depth, controls and sizes at the corner

The detail that decides a corner order is how the two shades meet. Decide which side runs all the way into the corner and which side stops against it, then allow for the depth of the first shade's cassette on the second side. Our smaller squared and round cassettes are 2 15/16 inches deep, the standard squared cassette 3 1/2 inches and the large squared cassette 4 3/16 inches. Put each shade's control on the outer edge, away from the corner, so two chains or wands are not fighting for the same few inches.

Corner windows are often generous on one side and narrow on the other, so check minimum widths too. Manual clutch loop roller starts at 11 3/4 inches, cordless roller at 19 3/4 or 23 5/8 inches depending on the cassette, and motorized roller between 20 1/8 and 21 1/4 inches. At the wide end, light filtering roller reaches 96 inches on the smaller cassettes and 98 3/8 inches on the standard squared cassette, while blackout and sunscreen goods stop at 86 or 94 1/2 inches, because the heavier fabrics are milled on narrower rolls. If you want both sides to move together, motorize them: one multi-channel remote can run both, and the AC152-06 remote supports time control so the sunny side can drop on its own schedule.

Measuring and installing a corner window yourself

Measure each side separately, even if the two panes look identical. Take the width at the top, middle and bottom and use the smallest, rounded down to the nearest 1/8 inch, then measure the height on both sides. For an inside mount the shade is built about 1/4 inch narrower than the opening to clear the frame. For an outside mount, add about 3 7/8 inches to width and height so the shade overlaps the opening, and remember that on the side that stops against the corner, that overlap has to come from the outer end.

Fitting needs a 6 mm drill bit, with bracket screws marked at 1.1 inch spacing and two anchor types in the box for drywall or masonry. Two screws on opposite sides hold each bracket on a sound wall. Hook the valance groove onto the bracket latch, press back until it clicks, and confirm both the top and rear have locked before you let go.

Order samples and hold them up on both sides of the corner at different times of day, since the same fabric can look quite different on two walls facing different directions.
