What Percentage Openness Should I Choose for Solar Shades?

One of the most common questions homeowners ask when selecting solar shades is: "What openness percentage should I choose?"

It sounds like a technical detail, but openness factor can dramatically affect how a shade looks and performs. Choose correctly and you can reduce glare, improve comfort, and maintain the view you love. Choose the wrong fabric and you may end up with too much sunlight, too little privacy, or a view that isn't what you expected.

At Polar Shades, we believe selecting fabric should start with understanding what you want the room to accomplish.

What Does "Openness Factor" Mean?

Solar screen fabrics contain tiny openings that allow light and visibility through the material. The openness percentage describes approximately how open the weave is.

A lower openness percentage generally provides more solar control and privacy during daylight hours. A higher openness percentage generally provides greater visibility through the shade.

Polar Shades offers numerous performance fabrics and openness levels so homeowners can balance view, glare control, privacy, and solar protection.

1% Openness: Maximum Solar Control

A 1% openness fabric has a very tight weave. This can be an excellent choice for rooms receiving intense direct sunlight, particularly west- and south-facing windows.

Homeowners typically choose lower-openness fabrics when reducing glare and solar exposure is more important than maintaining maximum view-through. These fabrics can work particularly well in:

• Bedrooms
• Media rooms
• Offices
• West-facing rooms
• Areas requiring increased daytime privacy

3% Openness: A Popular Balance

A 3% fabric provides a balance between visibility and solar protection. It still significantly reduces incoming sunlight and glare while providing greater visibility than a very tightly woven solar fabric.

For many homes in sunny climates such as Las Vegas and Phoenix, 3% can be an excellent starting point.

5% Openness: Preserve More of the View

A 5% openness fabric allows more visibility through the shade. This makes it popular for homes where preserving the view is a major priority.

Imagine a home overlooking the Las Vegas Valley, Red Rock Canyon, or the mountains surrounding Scottsdale. The homeowner may not want to cover that view. A carefully selected solar shade can reduce uncomfortable glare while maintaining a connection to the outdoors.

What About 10% and Higher?

Higher-openness fabrics provide even greater visibility, but they also allow more light through the fabric. These fabrics may be appropriate for certain architectural and commercial applications where maintaining the view is particularly important.

The correct choice depends on the direction the window faces and the amount of solar exposure it receives.

Dark Fabric vs. Light Fabric

Color matters too. Dark solar fabrics can provide excellent glare reduction and often produce clearer outward visibility. Lighter fabrics tend to create a softer, brighter appearance and can reflect more solar energy.

That's why two fabrics with the same openness percentage can feel very different inside a room.

Don't Choose One Fabric for the Entire House Automatically

This is one of the biggest mistakes homeowners can make. A north-facing bedroom does not necessarily have the same requirements as a west-facing great room.

The best shading design considers each exposure individually. You might use one openness factor in your main living space and another in bedrooms or areas exposed to intense afternoon sun.

And Remember: Solar Shades Are Not Blackout Shades

A solar shade is designed primarily to manage sunlight, heat, glare, and view. If you need significant room darkening or privacy, particularly in a bedroom, a blackout shade may be more appropriate.

Another option is a Duo Shade system that combines two fabrics, allowing homeowners to have solar control during the day and room darkening when desired.

Frequently Asked Questions

What openness percentage should I choose for solar shades? The right openness percentage depends on the window's direction, sun exposure, and your priorities. 1% offers maximum solar control and privacy, 3% balances visibility with glare reduction, and 5% preserves more of the outward view.

What's the difference between 1%, 3%, and 5% openness fabric? 1% openness has the tightest weave and offers the most glare and heat reduction with the least visibility. 3% balances comfort, visibility, and heat reduction for most rooms. 5% allows more natural light and a clearer outward view, with less solar control than tighter weaves.

Does fabric color affect solar shade performance? Yes. Dark fabrics generally provide better glare reduction and clearer outward visibility, while lighter fabrics create a softer, brighter appearance and reflect more solar energy, even at the same openness percentage.

Should every room in my house have the same shade fabric? No. Different rooms have different sun exposure and purposes, so the best approach considers each window individually rather than applying one openness percentage throughout the entire home.

Are solar shades the same as blackout shades? No. Solar shades are designed to manage sunlight, heat, and glare while maintaining some visibility, while blackout shades block light entirely for maximum privacy and room darkening, which is why bedrooms often use blackout fabric or a Duo Shade system instead.
