A sliding window with a fixed transom window above it. The sheer shade covers only the lower window and rolls up into a slim cassette, so the top glass stays clear.
How do you cover a window that has a transom window above it?
Shade the lower window and leave the transom open. A slim cassette mounted between the two lets the top glass keep pulling in daylight while the main window gets full control.
This Escondido window is a good example. A sliding window sits low on a white wall, and above it is a separate fixed pane, a transom that shows the treetops. If you hang one tall shade over both, you lose that upper light every time you lower it. So we mounted the sheer shade right on the frame between them. Raised, the fabric rolls up into a white cassette that looks like part of the trim. Below it the yard shows in full: green lawn, a black iron fence, and a white fence along the back.
The transom does its own work all day. It lets light in high on the wall, where it bounces off the ceiling and spreads across the room. Leaving it bare costs you very little privacy, because nobody sees in through glass that high.
What is the difference between sheer shades and regular roller shades?
A sheer shade has two thin layers of fabric with soft vanes between them, and the vanes tilt. A roller shade is one flat sheet that only goes up and down.
That tilt is the whole point. With a roller, your choices are covered or open, plus whatever the fabric lets through. A sheer shade adds a middle setting. Lower it and open the vanes, and you see out through the front sheer while the glare drops. Close the vanes and the fabric becomes a solid, private panel. Raise it all the way and it disappears into the cassette.
Rollers still win in some spots. They are simpler, often cost less, and come in blackout fabric that sheers cannot match. In a bedroom that has to get dark, we usually point people to a roller shade instead. But for a living space with a pleasant yard and strong afternoon sun, sheer shades give you more ways to set the light without ever losing the view. That is why they suited this window.
How do sheer shade vanes handle strong afternoon sun in Escondido?
They spread it out. Light passes through the front sheer, hits the fabric vanes, and comes into the room soft and even instead of in a hard beam.
The close view of this shade shows it well. The sun is low and bright, coming straight at the glass. Behind the fabric you can see the shadow of the window frame and the edge of the slider, but the light itself is a warm, glowing white, with each vane lit along its curve. Nothing is glaring. That is the job sheer shades do best in inland North County, where afternoons get hot and the light comes in low and strong.
Vane angle is the control. Tilt the vanes nearly closed and you dim the room while keeping a hint of what is outside. Open them wider when clouds roll in. Fabric also cuts some heat at the glass compared with a bare window, though a sheer is about light more than insulation. If heat is the bigger problem, our window treatments in Escondido often pair sheers with a cellular shade on the sunniest side of the house.
Is a cassette worth it on sheer shades?
For most windows, yes. A cassette is the cover that wraps the fabric roll at the top, and it makes the raised shade look finished instead of like a bare tube of fabric.
On this window it does two jobs. It hides the roll, which matters on a sheer because the stacked layers and vanes look busy when exposed. It also gives the transom a clean line to sit on, so the top window looks framed on purpose, not cut off by hardware. The white cassette matches the white trim and walls. When the shade is up, the eye goes straight past it to the yard.
A cassette also keeps dust off the fabric while it is rolled up, which helps over the years. We check the frame depth and the space between the two windows before ordering, because the cassette has to fit that strip exactly. If you have a window with a transom, a skylight, or an odd shape above it and are not sure how to treat it, book a free in-home consultation and we will measure it and show you options on the spot.
