Which Way Does Your Patio Face? Picking the Right Solar Shade

People shop for exterior shades by colour and motor, then wonder why the patio is still hot at five o'clock — or why they can't see the yard anymore. Almost always, the mesh was picked without anyone asking which direction the space faces. It's the first question we ask, and it costs nothing to get right.

What openness factor actually means

Shade mesh is rated by openness factor — the percentage of the weave that's open space rather than yarn. Typical exterior fabrics run from around 1% up to about 14%.

• Low openness (roughly 1–3%): tight weave. Blocks the most heat and glare, gives the most privacy, and gives up the most view.
• Mid openness (around 5%): the common middle ground. Meaningful heat control while keeping a usable view.
• High openness (10% and up): open weave. Keeps the view close to intact, takes the edge off glare, but won't rescue a west-facing patio in August.

There is no “best” number. There's only the right number for your exposure — which is why the direction question comes first.

Your patio's direction, one by one

West-facing — the hard case

This is the one that drives most calls. A west-facing patio takes low, direct sun through the exact hours people want to sit outside. Low sun angle means the light comes in sideways, under any roof you have, so a patio cover alone won't solve it. Go tighter here — this is where low-openness mesh earns its money, and where people who bought an open weave end up replacing it.

East-facing — easy

Hot early, comfortable by midday, pleasant all evening. If you use the space in the morning you'll want something; if you're an evening sitter you may barely need it. Mid or high openness is usually plenty.

South-facing — steady, but higher

Sun most of the day, but at a steeper angle for much of it, which means a roof overhang does more of the work than it can on a west wall. Mid openness handles most south-facing patios. Watch the winter months, when the sun sits lower and reaches further under the cover.

North-facing — often nothing needed

In Northeast Florida a north-facing patio gets very little direct sun. If that's you, be honest about whether you have a sun problem at all. You may be better off spending the money on a retractable screen for bugs, or on nothing.

The trade nobody explains

Every bit of heat you block costs you view. That's not a flaw in the product, it's physics — the yarn doing the blocking is the same yarn interrupting your sightline.

Two things people find out afterwards:

• Shades work one way in daylight. During the day you can see out better than people can see in. After dark with the patio lights on, that reverses — you're the lit side. If evening privacy matters, that changes the calculation.
• Darker fabric sees out better; lighter fabric blocks more heat. It feels backwards. A dark charcoal mesh cuts glare and preserves the view; a light fabric reflects more heat but scatters light and looks hazier from inside.

None of that is complicated once someone tells you. It's just rarely mentioned before the sale.

When you don't need a shade at all

Save your money if:

• Your problem is bugs, not sun. Shades don't stop insects. That's a screen, and we say so on every quote where it comes up.
• You face north and you're buying because a neighbour did.
• Deep shade already covers you. Mature oaks and a generous overhang do a lot of this job for free.
• You only sit out in the morning on an east-facing patio — you're shading hours you don't use.

We'd rather size one shade correctly than sell you three. Same principle as rescreen versus rebuild — the smaller right answer beats the bigger wrong one. More on how we spec these on the motorized and solar shades page.

FAQ

Which direction is worst for afternoon sun in Florida?

West, comfortably. Low afternoon sun comes in at an angle that gets underneath roofs and overhangs, which is why west-facing patios stay hot even when they're covered.

Do solar shades actually lower the temperature?

They cut radiant heat and glare, so the space feels considerably cooler and surfaces stay less hot. It's not air conditioning — it's shade, doing what shade does, in the exact hours you need it.

Can I see out at night through a solar shade?

Less well than during the day, and people can see in more than they can in daylight. If you use the patio after dark with lights on and privacy matters, factor that in before choosing an open weave.

Can I use different shades on different sides of the house?

Yes, and on a house with very different exposures that's usually the right call — a tighter weave on the west side, something opener where the sun is milder.

Can shades be added to a screen enclosure I already have?

Often, provided there's a solid, square surface to mount the housing and tracks to. We look at the existing frame first, because what we're fixing to matters more than the shade itself.
