Insulated vs Non-Insulated Patio Covers: Which Is Better in Arizona?
For most Arizona homes, an insulated patio cover is the better choice if you plan to actually sit under it in summer. A non-insulated aluminum cover blocks the sun, but the metal itself heats up and radiates that heat down on you, while an insulated panel keeps the underside much closer to the shade temperature of the air.
That's the short answer. We've already compared W-pan and flat pan, which are both non-insulated styles, and looked at whether a cover lowers your cooling bill. This post is about the roof panel itself and how it feels to stand under it in July.
What Makes an Insulated Patio Cover Different
An insulated panel is a sandwich: two aluminum skins with a rigid foam core bonded in between. Common thicknesses are 3, 4 and 6 inches, and the thicker the foam, the less heat gets through.
A non-insulated cover is a single layer of aluminum, either a W-pan profile or a flat pan. It's lighter and simpler, and it still throws real shade.
The difference you feel is radiant heat. On a 112-degree afternoon, the top of any metal roof gets hot enough to fry an egg. With a single skin, the underside gets close to that too, and you feel it on your head and shoulders. With foam in the middle, the underside stays near the temperature of the shaded air.
Where Each Type Makes Sense
After more than 20 years building shade around the Valley, here's how I break it down for homeowners.
Go insulated when:
• The cover is attached to the house over a patio you use every day
• It shades windows or a slider into a living area
• You want ceiling fans, recessed lights or misters built in
• You don't love the sound of monsoon rain drumming on metal
Non-insulated is fine when:
• It's a carport or covers a walkway
• The space is mainly shade for a west wall, not a place to lounge
• Keeping the project simple matters more than comfort underneath
A Backyard We Redid in Goodyear
A few summers back, a family in Goodyear called us about a non-insulated cover another company had put up. Nice looking, solid build. The problem was they never used it. By 3 p.m. it felt like standing under a griddle, and the slider into their family room stayed hot to the touch.
After checking that the posts and beams could carry the extra weight, we swapped the roof for 4-inch insulated panels on the same frame. Same shade footprint, completely different space. They told us the dog finally started napping out there, which might be the best review we've ever gotten.
The Honest Downsides of Insulated Panels
Insulated isn't automatically right for everyone. It costs more up front than a single-skin cover. The panels are heavier, so the footings and beams have to be sized for them, and that matters if you're thinking about reusing an existing frame. Some HOAs also have opinions on roof thickness and fascia, which is one reason we handle HOA approval and permit paperwork for our customers.
And if your cover is mostly for keeping the car out of the sun, a non-insulated flat pan patio cover or W-pan will do the job without the extra
weight.
How Insulation Ties Into Comfort and Energy
An insulated cover shades your windows and also keeps the patio slab from turning into a heat sink right next to the house. We looked at the energy side in do patio covers really lower your cooling bill. The short version: shade on west and south glass helps, and an insulated roof helps more because less heat radiates toward the house.
You can see panel options on our insulated patio covers page, and our patio covers in Phoenix page shows the styles we install across the Valley.

Frequently Asked Questions
How much cooler is it under an insulated patio cover?
It depends on panel thickness and sun angle, but the underside of an insulated panel stays much closer to the shaded air temperature than a single-skin metal roof, which can feel hot overhead.
Can I put lights and fans in an insulated patio cover?
Yes. The foam core makes it easy to run wiring and mount fans and recessed lights.
Can I convert my existing cover to insulated panels?
Often, yes, as long as the posts, beams and footings can carry the added weight. We check the frame before recommending it.
