If Your Arcadia or Paradise Valley Home Has Big West-Facing Windows, This Summer Has Been Rough
Phoenix has repeatedly hit 113°F to 116°F this summer, and the city has rolled out nearly two dozen heat-response measures — including 24-hour respite centers and extended library hours — just to help residents get through it. For homes with large expanses of west-facing glass, a common architectural feature in Arcadia’s ranch homes and Paradise Valley’s mid-century and contemporary builds, that heat translates directly into higher afternoon cooling costs.
Why Large-Glass Homes Feel the Heat Differently
Glass transmits solar heat far more efficiently than stucco or block wall. A home with a wall of west-facing windows — exactly the kind of layout that makes Arcadia and Paradise Valley architecture desirable — absorbs a disproportionate amount of solar heat during the hardest hours of a Phoenix afternoon, right as temperatures peak in the 110s. That heat load doesn’t just make rooms uncomfortable; it’s a big part of what drives summer electric bills into the highest tier most Arizona utilities charge.

Where a Security Screen Fits Into an Energy Strategy
A security screen isn’t a substitute for solar screens or low-E window film, and Boss won’t tell you it is. What it does add is a layer of shading directly in front of the glass, on the same window or door where you’d otherwise need a separate product to get any solar benefit at all — plus the ability to actually open that window or door for airflow during the cooler morning hours without giving up a secured entry point.
For a lot of Arcadia and Paradise Valley homeowners, that combination — some shading, plus the option to ventilate safely — ends up mattering more day-to-day than a screen’s headline energy-savings number.
What This Looks Like on a Typical Large-Window Home
West-facing sliding doors and picture windows get the heaviest solar load and benefit most from added shading
Pool-facing doors that get opened and closed constantly in summer are also common break-in points, so security and ventilation end up being the same conversation
Older Arcadia homes with original steel or aluminum-frame windows often have gaps around the frame that a properly fitted security screen install can also help tighten up
“On a house with that much glass, people are often surprised how much difference it makes just to have something between the sun and the window during the hottest part of the day,” says James Kerr, a security screen specialist at Boss Security Screens. “It’s not the whole answer to a Phoenix summer, but it’s a piece of it — and you get real security at the same time.”
Frequently Asked Questions
Will a security screen lower my electric bill in Phoenix?
It can modestly reduce solar heat gain on the covered window or door, which helps cooling costs somewhat, though it isn’t designed or marketed as a primary energy-savings product.
Why do Arcadia and Paradise Valley homes run hotter than newer subdivisions?
Many homes in these areas feature large expanses of west-facing glass as part of their mid-century or contemporary architectural style, which increases solar heat gain compared to homes with smaller window openings.
How hot has Phoenix gotten this summer?
Phoenix has repeatedly reached 113°F to 116°F in 2026, prompting the city to roll out nearly two dozen heat-response measures for residents.
Can security screens be custom-fit to older window frames?
Yes, Boss custom-measures and fits every installation, which matters for older Arcadia homes with original steel or aluminum window frames.
Does a security screen block sunlight, or just add security?
A security screen’s mesh does block a portion of direct sunlight, in addition to its primary function of securing the opening.
