It's normal for homes in Mesa to feel like giant ovens for much of the year because of the relentless heat. If you don't have the right windows installed, your AC may run around the clock trying to combat the brutal desert sun. 

The constant, intense UV exposure not only fades your interior furniture and flooring but also physically compromises the integrity of the glass. 

Keep reading to learn how heat affects glass and how to fortify your home against the intensity of the Arizona sun.

Why Arizona Heat Causes Thermal Stress in Glass Windows

Windows experience thermal stress from the Arizona heat when the center of the pane gets much hotter than the outer parts. The temperature difference creates a kind of tug-of-war that makes the glass expand and contract, often leading to hairline cracks or eventual shattering. 

How Extreme Heat in Mesa AZ Leads to Window Expansion and Cracking

In Mesa, it's not unusual for it to be well over 110 degrees for weeks at a time. Day after day, the blistering sun puts immense pressure on glass through window expansion heat in Arizona. When the hot glass pushes against the window frame, it may develop micro-fractures, warped seals, or pane separation. 

Heat cracks often start out small at the edge of the window. As time goes by, they usually get larger and spiderweb across the entire glass surface.

Common Glass Problems from Sun Damage in Mesa Homes

The flexible seals on double-pane windows are vulnerable to deterioration from the intense Arizona sun. They may become brittle or snap out of place as they expand and contract. 

Once a seal is gone, there's a much higher chance of moisture building up between the panes. You might notice a foggy look that doesn't go away or streaking on the inside of the glass.

Unsightly haze isn't the only thing you have to worry about with sun damage to windows in Arizona. After years of absorbing Mesa's harsh UV rays, the glass loses its ability to flex. Even a minor vibration may result in the glass shattering.

Why Tempered Glass for Windows is Ideal for Arizona Heat

Tempered glass works great in Arizona homes because it's heat-treated. It does a much better job at withstanding extreme temperature swings when compared to regular glass. You'll be able to keep your home cool and secure, even during record-breaking heatwaves. 

A big plus is that if the glass breaks, it won't shatter into dangerous, sharp shards. Instead, it will crumble into small, pebble-like pieces.
