When shopping for window coverings, solar shade openness is one of those terms that can either feel like insider knowledge or complete jargon.
It sounds technical, but at its core, it’s simply about how tightly or loosely the fabric is woven. When you shop for solar screen shades, the level of openness greatly affects how much privacy you have and how comfortable your space stays.
Understanding it isn’t just helpful; it’s the difference between shades that are “good enough” and shades that truly fit your life.
What Exactly Is Openness?
Openness is measured in percentages, usually ranging from 1% to 10%. The number refers to the amount of open space in the weave of the fabric. Lower numbers mean smaller gaps—the room is darker, more heat is blocked, and privacy is better.
Higher numbers let in more light and keep your outdoor view sharper, but they offer less sun protection and can compromise privacy, especially after dark.
Think of it like sunglasses. A pair with dark, polarized lenses (low openness) shields you more from glare but can slightly dim your view. A lighter pair (high openness) feels airier and brighter but offers less shade from intense sunlight.
How Openness Affects Heat and Glare
If your main concern is keeping rooms cooler, you’ll want to lean toward fabrics with lower openness. A 1% or 3% openness blocks most of the sun’s rays before they even hit your windows, which can make a noticeable difference in room temperature.
That said, there’s a balance to strike. While a lower openness is excellent for heat reduction, it also makes a space feel a bit darker—great for a home theater, maybe less ideal for a sunroom.
Mid-range openness levels, like 5%, still control glare effectively while letting in more natural light, so you’re not left switching on lamps in the middle of the day.

This is one of the reasons solar shade openness is such a big deal—it’s not just about blocking light; it’s about shaping how a room feels throughout the day.
The Privacy Factor
Here’s where things get tricky: solar shades are generally quite good at providing privacy, but they’re designed for daytime privacy, specifically. In bright daylight, the outside is lit and the inside is relatively dim, so people can’t see in easily.
But once the sun sets and your lights are on, the effect reverses. A lower openness fabric helps, but if nighttime privacy is a priority, you might need to pair solar shades with curtains or layer them with blackout roller shades.
Daytime Views vs. Comfort—Your Personal Sweet Spot
If you have a beautiful backyard or a city skyline you can’t get enough of, you might lean toward 5%–10% solar shade openness to keep that view clear.
But if your windows face a busy street, sacrificing a bit of the view for more privacy and heat control might be worth it.
Many homeowners end up choosing different openness levels for different rooms—tighter weaves for bedrooms and more open weaves for living spaces. It’s not a one-size-fits-all decision, and that’s a good thing.
Choosing Openness Like a Pro
- 1%–3%: Best for heat control, glare reduction, and daytime privacy.
- 5%: Balanced light control with a decent view outside.
- 7%–10%: Maximum visibility with minimal glare reduction.
If you’re unsure, request fabric swatches and hold them up to your windows at different times of day. You’ll see instantly how they affect the light, your view, and your sense of privacy.
