Solar shades are one of the best window treatment options for Toronto homes and condos because they reduce glare and UV while keeping your space bright. The part that confuses most people is openness percentage. You will see numbers like 1%, 3%, 5%, and 10%, and it is not always obvious what they mean in real life.
This guide explains openness in plain language, how it affects privacy and view, and how to choose the right level for each room. You will also see when it makes sense to layer solar shades with another fabric for full nighttime privacy.
What Openness Percentage Actually Means
Openness percentage describes how tight or open the weave is in a solar fabric. A lower number means a tighter weave. A higher number means a more open weave.
- Lower openness (1% to 3%) blocks more light and glare, increases daytime privacy, and reduces UV exposure.
- Mid openness (5%) balances glare control with a clear view.
- Higher openness (10% and up) keeps the room brighter and the view more open, but reduces glare control and privacy.
Think of it like sunglasses. A lower openness is like a darker lens. A higher openness is like a lighter lens.
How Openness Affects View, Glare, and Privacy
View to the outside
If your main goal is keeping a view, you will likely prefer a more open fabric. A 5% openness often keeps a strong view while still cutting glare. A 10% openness can feel almost like a light screen, especially during the day.
If you want the sharpest view with minimal haze, colour matters too. Many people find darker solar fabrics maintain a cleaner view, especially in condos with big glass and city sightlines.
Glare control
Glare is the main reason people buy solar shades. Lower openness levels reduce glare more effectively, which matters if you have a TV facing the windows or work at a desk near the glass.
- For strong glare, start with 3%.
- For moderate glare, 5% is often enough.
- For light glare or north-facing windows, 10% may work.
Daytime privacy
Solar shades give privacy during the day based on a simple rule. If it is brighter outside than inside, it is harder for people to see in. The tighter the weave, the stronger the privacy effect.
- 1% gives the most daytime privacy.
- 3% gives excellent privacy for most condos.
- 5% gives good privacy while keeping the view.
- 10% gives the least privacy, especially when you are close to other buildings.
Nighttime privacy
This is where people get surprised. At night, interior lights make it easier to see into your home, even through solar fabrics. Openness helps, but it does not change the physics. If full nighttime privacy is important, plan to layer your solar shade with a second option such as a blackout roller, room-darkening fabric, or drapery.
Many Toronto condo owners choose a dual roller system. They use solar during the day for the view and glare control, then lower a privacy or blackout fabric at night.
Quick Room-by-Room Recommendations
Living rooms with a view
If you have a skyline or treetop view you want to keep, 5% is usually the best starting point. It reduces glare and UV while keeping the room bright. If the sun is intense and you still want strong view, consider 3% in a darker colour.
Home offices
For screen glare, aim for 3% or 5%. If you are on video calls or you have a monitor facing the windows, 3% can be a noticeable improvement. If you want the room to feel brighter, 5% is a safe pick.
Bedrooms
Solar shades can work in bedrooms if you want a view and soft daylight, but they are not the best solution for sleep. Most bedrooms benefit from blackout or room-darkening at night. A strong combo is solar at 3% or 5% for the day, plus blackout for the night using a dual roller.
Kitchens and dining areas
Kitchens need daylight, but direct sun can be uncomfortable, especially in west-facing rooms. 5% is a great all-around choice here. If you have intense afternoon sun, 3% will reduce heat and glare more effectively.
Floor-to-ceiling condo windows
For tall glass, the most common choices are 3% or 5%. If you are close to neighbouring towers, 3% will typically feel more comfortable from a privacy standpoint. If you are higher up with a wide-open view, 5% can look amazing and still control glare.
Exposure Matters: North, South, East, and West
Toronto light changes dramatically based on orientation.
- South-facing windows get strong midday sun. Start with 3% or 5%.
- West-facing windows get harsh afternoon glare and heat. 3% is often best.
- East-facing windows get bright morning sun. 5% usually works well.
- North-facing windows get softer, indirect light. 5% or 10% can work depending on privacy needs.
If you do not know your exposure, you can still choose by paying attention to the time of day you feel glare most.
Openness vs Colour: A Simple Rule
Openness is not the only factor. Fabric colour changes how the shade feels.
- Darker solar fabrics often improve view clarity and reduce glare.
- Lighter solar fabrics reflect more heat and keep rooms looking bright, but may feel more transparent at night.
This is why it is important to see samples in your own unit. A fabric that looks perfect in a showroom can look different with your flooring, wall colour, and amount of daylight.
When to Layer Solar Shades
Layering is the best way to get the view in the day and privacy at night. Consider layering when:
- Your condo faces another building
- You use the room at night with lights on
- You want better sleep and full darkness
- You have a media room or bedroom on a bright street
Dual rollers are a clean, modern way to do this without bulky hardware. You can keep your daytime solar shade down most of the time, and only use blackout when needed.
