How Exterior Shades Can Reduce Patio Temperatures by Up to 20 Degrees This Summer
Summer Was Made for Outdoor Living
There is something special about spending time outdoors.
Whether you're enjoying dinner beneath a covered patio, relaxing beside the pool, entertaining friends around an outdoor kitchen, or simply watching the sunset with family, outdoor living has become one of the most important extensions of today's home.
Homeowners routinely invest thousands of dollars in creating beautiful outdoor spaces. They install decorative pavers, outdoor fireplaces, premium furniture, custom kitchens, televisions, lighting, and professionally designed landscaping to create an environment where family and friends naturally gather.
Yet every summer, many of these same spaces sit empty during the hottest part of the day.
The patio furniture is too hot to touch.
The concrete radiates heat.
The sun creates an uncomfortable glare.
Instead of enjoying the backyard, everyone retreats indoors.
Many homeowners believe this is simply part of living in warm climates like Nevada, Arizona, California, or Texas.
The truth is, it doesn't have to be.
A professionally designed exterior shade system can dramatically reduce heat buildup, improve comfort, protect your outdoor investments, and completely change the way you use your backyard.
At Polar Shades, we've spent decades helping homeowners transform outdoor spaces into places they can enjoy throughout the year—not just during the cooler months.
Why Patios Become So Hot
Most people assume outdoor discomfort comes from high air temperatures alone.
In reality, the greatest contributor to patio heat is something called solar heat gain.
As the sun shines on your home, patio, and surrounding surfaces, energy is absorbed by materials such as:
- Concrete
- Decorative pavers
- Natural stone
- Stucco
- Glass
- Brick
- Outdoor furniture
- Pool decking
- Metal railings
These materials don't simply become warm—they store enormous amounts of heat throughout the day.
Even after the sun begins to move or set, they continue releasing that stored energy back into the surrounding environment.
This is why patios often remain uncomfortable well into the evening.
Many homeowners are surprised to learn that the surface temperature of concrete can exceed 140 degrees Fahrenheit on a hot summer afternoon.
That heat radiates upward, making the entire outdoor environment feel significantly hotter than the actual air temperature.
When reflected sunlight from windows, water features, and light-colored surfaces is added to the equation, the result is an outdoor space that can feel 10 to 20 degrees hotter than the local weather forecast.
Understanding this process is the first step toward solving it.
Exterior Shades Stop Heat Before It Becomes a Problem
One of the biggest misconceptions homeowners have is believing interior blinds or window coverings provide the same benefit as exterior shades.
While interior shades certainly help reduce glare and improve privacy, they address sunlight only after it has entered the building.
Exterior shade systems work in an entirely different way.
Instead of reacting to solar heat, they prevent it.
By intercepting sunlight before it reaches your patio, windows, doors, and outdoor living areas, exterior shades dramatically reduce the amount of heat absorbed by surrounding surfaces.
This creates several immediate benefits:
- Cooler patio temperatures
- Reduced glare
- More comfortable seating areas
- Protection from harmful UV rays
- Improved energy efficiency
- Extended outdoor living hours
High-performance solar screen fabrics can block up to 95% of harmful ultraviolet radiation while maintaining outward visibility and allowing natural airflow.
Rather than enclosing your outdoor space, they create a cooler, more enjoyable environment that still feels open and connected to your surroundings.
More Than Comfort—Protecting Your Investment
Today's outdoor living spaces represent a significant investment.
Many homeowners spend tens of thousands of dollars creating backyard environments designed for relaxation and entertainment.
Unfortunately, prolonged exposure to ultraviolet light causes gradual damage that often goes unnoticed until it becomes expensive to repair or replace.
Outdoor furniture begins to fade.
Cushions lose their vibrant colors.
Wood dries and cracks.
Decorative finishes deteriorate.
Televisions and electronics are exposed to unnecessary heat.
Flooring materials weather prematurely.
A professionally engineered exterior shade system acts as a protective barrier, dramatically reducing direct UV exposure and helping preserve the beauty and value of these investments for years to come.
For many homeowners, the savings from extending the life of outdoor furnishings alone can offset a significant portion of the investment in a premium shade system.
