Frequently Asked Questions


We love it. We hate it. Whatever side of the fence you find yourself on, if you reside in the Arizona desert, you eventually learn to respect the undeniable power of the sun. It brings us out. It drives us in. The barriers we put up against the relentless force that powers our planet are supposed to protect us, but do they?

Nope. As it turns out, the light let in through common windows can actually cause cancer[1].

UVA: The Ray That Got Away

Most people know to cover up with clothing or sunscreen when going about their day-to-day outdoor activities, but who thinks to do the same when in the air conditioned comfort of a home or office? Untreated glass windows allow UVA rays to pass through unimpeded, as if there was no barrier at all[1].

There is very little data available to quantify how much sun exposure desert dwellers encounter while inside, but the fact remains that any exposure could mean disaster in the long-term. The UVA ray penetrates deeper than UVB ray, and can cause cancer as well as premature aging of the skin[1].

Who is at Risk?

No one in particular is "immune" to the threat posed by exposure to solar radiation.

Younger individuals, particularly children and adolescents, should avoid accumulating exposure to ultraviolet (UV) radiation. This accumulation is thought to be a primary factor in the development of skin cancer in patients later in life[2].

Many seek out the warmer climate as a safe haven to retire to in their golden years, but recent studies suggest that the older your skin is, the more "prone to infection and cancer" it is[3].

Fair-skinned Arizonians must be especially cautious when managing UV exposure, but that doesn't mean dark-skinned people are immune[2]. While the effects of the sun might be seen more rapidly on a fair-skinned person, the long-term effects of repeated sun exposure can be equally devastating to a dark-skinned person[2].

Limiting Exposure

Some exposure to the sun is necessary to maintain proper Vitamin-D production, but the experts agree that you only need a limited amount of sun to achieve health and well-being.

In fact, less than half an hour twice a week is all you really need[4]. As skin cancer is now the most common form of skin cancer in America[5], any unnecessary exposure should be considered potentially hazardous.

Protect Yourself Properly

Wearing proper clothing or sunscreen when indoors is an effective method for keeping yourself safe from the harmful radiation coming through the window, but unfortunately it's not always possible.

An easy way to guarantee your safety is to have a UV blocking film applied to your pre-existing windows, or to request new windows be installed that already have technology embedded that prohibits any solar radiation from passing through.
