Light-filtering shades in Madison homes give good privacy by day and partial privacy at night. After dark, a lit room behind a light-filtering fabric hides faces and details. It can still show shapes and movement to someone on the sidewalk. That's fine in a kitchen. Bedrooms, baths and busy front rooms need a second layer or a denser fabric.

In early December you'll want that privacy before 5 p.m.

Why does night privacy matter so much in a Madison December?

Because the evening starts so early. The sun sets at 4:23 p.m. in Madison from about December 5 to December 12, per the U.S. Naval Observatory. By about 4:55, twilight fades and the street is dark. Dinner, homework and the evening news all happen with the lamps on.

Mornings are dark too. On December 21 the sun doesn't rise until 7:26 a.m. If you get ready in a lit bathroom or bedroom, that window is on display twice a day.

The cold keeps shades down longer as well. December normals in Madison are a high of 32.3°F and a low of 18.2°F. The month also brings about 12 inches of snow, says the Wisconsin State Climatology Office. Most of us close up the house at dusk and leave it that way until morning.

Do light-filtering shades provide privacy at night?

Partly. A light-filtering fabric lets daylight pass through and scatters it. During the day the street is brighter than your room. People outside mostly see a soft, even glow.

At night that flips. Your lamps make the room brighter than the street. Now the shade is lit from behind, like a lamp shade. Anyone close by can tell when someone walks past. With a thin or pale fabric they may see clear outlines.

Think of light-filtering shades as a daytime fabric first. They're great for the dining room, the kitchen and a home office you leave at 5. They're not always enough for rooms you use after dark.

What makes one light-filtering fabric more private than another?

A few details change the answer more than the label does.

Weave and weight. A tighter, heavier weave shows less. Hold a sample up to a lamp and you'll see the difference right away.
Color. Pale fabrics glow brighter at night. Mid-tone neutrals hide more.
Where the lamp sits. A lamp right next to the window throws a sharp shadow onto the fabric. Move it a few feet into the room and outlines blur.
Edge gaps. Light leaks at the sides of an inside-mounted shade. An outside mount that overlaps the frame cuts those gaps.

How can you keep the daytime glow and still get privacy at night?

You don't have to give up the soft light you like. You just add a way to close things up after sunset. These four options are the most common.

Option	Daytime light	Privacy after dark	Good fit for
Denser light-filtering fabric	Softer, a bit dimmer	Better, still shows some shapes	Living rooms, dining rooms
Dual roller (light-filtering and blackout in one casing)	Full glow with the light layer down	Strong with the blackout layer down	Bedrooms, front rooms
Light-filtering shade plus drapery	Glow from the shade alone	Strong with the drapery closed	Front living rooms, primary bedrooms
Room-darkening shade	Dark when lowered, full light raised	Strong	Bedrooms, baths, TV rooms

What's the difference between room darkening and blackout?

Room darkening fabric blocks most light, but a faint glow can come through. Blackout fabric blocks nearly all light through the fabric itself. With either one, a little light can leak at the edges. People pick blackout for daytime sleepers or anyone who wakes with the first gray light. For night privacy alone, room darkening usually does the job.

Which rooms need more than light-filtering?

Think about who is in the room after dark and how close the window is to other people.

Bedrooms and baths come first. Next is any front room that faces a sidewalk or sits a driveway's width from the neighbors. Take Third Lake Ridge, the oldest part of the Marquette neighborhood. Most of its buildings are Victorian-style homes, the City of Madison notes. If your front room faces the sidewalk, give it the same care as a bedroom.

Smart shades can help too. Set them to lower at sunset and you never come home to a lit, open window. Our post on Madison's daylight swings and smart shades covers how schedules work.

What should you check before you choose?

Stand outside one evening with the lamps on. Look at the rooms you care about most. Then make a short list:

Which rooms do you use after dark?
Do you want daylight there, or mostly privacy?
Is the lamp close to the window?
Would you open and close a second layer every day, or would you rather have one shade do it all?

Need a little more cover? Try a denser fabric. Need strong privacy and soft daylight? Add a second layer.
