Not All Shade Is Equal: Choosing the Right Shade for Your Patio

We’re lucky in South Africa. We get to enjoy pleasantly warm weather for most of the year. It’s one of the reasons stoep and patio living plays such a big role in how we spend our time.

But around midday, it can become nearly unbearable to sit outside.

The good news? It’s fixable. With the right setup, your outdoor space can stay cool and comfortable, even during the hottest part of the day.

First, it helps to understand what’s actually causing all that heat.

WHAT CAUSES THE HEAT?

It’s not just the sun itself. It’s a combination of factors all working together:

  • Heat absorption and storage

    Your paving, walls, and furniture sit in direct sun for hours, absorbing and storing heat.

  • Heat radiation
    Later in the day, that stored heat gets released back into the space. That’s why your patio or outdoor area can still feel hot, even after you’ve put up an umbrella or closed your pergola shutters.
  • Lack of airflow
    If air can’t move freely, heat builds up and lingers, especially under solid roofs or enclosed patios.
  • Exposure time
    A patio that gets full-day sun behaves very differently from one that only gets morning light. The longer the exposure, the more heat it holds.

Put it all together, and you’re left with a space that doesn’t just get hot, but stays hot.

BEAT THE HEAT: CHOOSE THE RIGHT SHADE

Not all shade is created equal. Some options simply block sunlight, while others actually help reduce heat buildup.


Here’s how the most common solutions compare:

Pergolas

Pergolas are permanent, built-in structures, often made from steel or wood, that can turn a patio into a defined outdoor living space. Some feature slatted designs, others use adjustable louvres, while some incorporate solid roofing.6

Pros:

  • Strong, durable, and built for long-term outdoor use
  • Adds a premium, architectural feel and can increase property value
  • Can be used to integrate lighting, plants, or additional shade systems

Cons:

  • Expensive compared to other options
  • Slatted designs don’t provide full shade, you’ll still get heat and glare unless you have louvres that can fully close
  • Adding a solid roof can trap heat and reduce airflow
  • Requires maintenance, especially in coastal or humid areas
  • Fixed structure – no flexibility once installed

Instant Gazebos

In South Africa, gazebos are usually the pop-up type, more suited to camping, markets, or occasional use.

Pros:
  • Quick and easy to set up
  • Portable and easy to store
  • Affordable for short-term use

Cons:

  • Not built for long-term outdoor exposure Struggles in wind and can be unstableDoesn’t offer a clean, permanent look
  • Materials degrade quickly in intense and continuous sun exposure

Canvas Covers and Umbrellas

Common in awnings and retractable systems, as well as standard umbrellas.

Pros:

  •  Blocks sunlight effectively
  • Can offer good UV protection with quality fabric
  • Works well in fixed or retractable setups

Cons:

  •  Limited airflow, which can make the space feel warmer
  • Tends to trap heat rather than release it
  • Requires regular cleaning and maintenance
  • Can fade and wear over time
  • Cheaper options do not offer high UV resistance

PVC Or Tarpaulin Covers

Flexible, tarp-style covers often used for temporary or budget-friendly shade setups.

Pros:

  •  Fully waterproof, making them useful where rain protection is needed
  • Blocks sunlight completely
  • Widely available and relatively inexpensive
  • Easy to install for quick coverage

Cons:

  • No breathability, so heat builds up quickly underneath
  • No breathability means a space can quickly feel hot and stuffy during summer
  • Can flap or strain in windy conditions if not secured properly
  • Generally not the most visually appealing option for a residential setting
  • Material can degrade, crack, or become brittle over time

Shade Netting

Lightweight netting typically used in gardens, parking lots or agriculture to reduce sun intensity rather than create full shade.

Pros:
  •  Allows air to move freely, preventing heat from getting trapped
  • Affordable and easy to install
  • Durable for its intended use

Cons:

  •  Provides partial shade only and does not block enough UV for comfortable patio use
  • Does not significantly reduce heat buildup in a living space
  • More functional than aesthetic, so it doesn’t suit most entertainment areas

OUR FAVOURITE: Woven Shade Sails

Designed specifically for outdoor living spaces where sun protection, comfort and appearance all matter.

Pros:

  • Blocks a high percentage of UV while allowing airflow
  • Helps prevent heat buildup instead of just blocking light
  • Creates a cooler, more usable space during peak heat
  • Clean, modern look that suits residential patios and entertainment areas
  • More cost-effective and less invasive than building permanent structures

Cons:

  • Needs correct installation and proper tensioning to perform well
  • Not waterproof, so it does not provide rain protection
  • Lighter or portable versions may need to be taken down in extreme weather

Each of these types of shade has its place, but the right choice depends on how your space is used and how exposed it is.

Matching the Right Shade to Your Space

For larger, fully exposed patios, a permanent solution is usually the best starting point.

These setups protect your space throughout the day, not just when you’re using it. That means less heat buildup, better protection for furniture, and a patio that’s actually usable during peak hours.

For smaller or partially exposed spaces, a movable option like an umbrella can work just as well. It gives you flexibility to adjust as the sun moves, without committing to a fixed structure.

The challenge is finding the right balance between sun protection, airflow, durability, ease of installation, and maintenance.

That’s exactly the gap we set out to solve with Kalahari Shade.

Why We Built Kalahari Shade

We were the original supplier of shade sails in South Africa, first introduced under the Coolaroo name in 2011. At the time, there was nothing like it locally.

The goal was simple: create a shade solution that could handle harsh sun, stand up to wind, and still be easy to install and maintain.

Woven shade sails offered that balance: UV protection without trapping heat, and durability without the bulk or cost of built structures.

From there, the range evolved to suit different types of spaces.

Kalahari umbrellas, for example, use the same HDPE woven fabric as our shade sails, making them more breathable and far easier to clean than traditional canvas umbrellas.

Today, that range covers a few different use cases. Choosing the right option depends on how your space is set up:

  • For permanent setups, Kalahari’s Standard range covers most homes, while the Extreme range is built for high-wind or exposed areas
  • For flexibility, Kalahari umbrellas offer adjustable shade that can be easily repositioned as the sun moves throughout the day
  • For something lightweight but more stable than a typical umbrella, the Easy Shade range sits in between

 

At the end of the day, it’s not about one “best” solution. It’s about choosing the right type of shade for your space, your climate, and how you actually use it.
