Sunlight can be extremely valuable for improving health and productivity. But if the sun’s UV rays are not controlled, they can cause damage to skin, floors and furniture, artwork, wallcoverings, and display merchandise.
Window film is a viable option for controlling UV rays, but it certainly isn’t the only option. How does window film stack up when compared to the most obvious sun-blocking alternative: window shades and blinds?
Window film and window shades both do a good job of preventing glare so tenants and occupants aren’t bothered by direct or reflected sunlight – but they do it in different ways. Window shades block or redirect sunlight so it doesn’t enter the space, so using them to prevent glare may mean an increase in artificial lighting requirements. Controlling excessive brightness, window film can prevent distracting glare while still letting in natural light.
Solar Heat Gain and Energy Savings
If you invest in high-performance, low-e window film, you can improve window insulating performance year-round instead of just during summer months. Low-e window film reduces heat loss in winter and solar heat gain in summer, resulting in both cooling and heating energy savings. Because window blinds and shades don’t always improve window insulating performance (they only provide improved insulating performance when down completely with blind slats closed), they can’t provide as much year-round energy savings as low-e window films. Window shades and blinds are located inside the room, so they also capture (absorb) and radiate solar heat into the space. Window film prevents a much higher percentage of solar heat gain from permeating the glass by reflecting the sun’s heat back outdoors.
Access to Safe, Natural Light
Window shades and blinds may create dark interior environments because they block a large amount of natural light. Window film works by blocking up to 99.9% of harmful UV rays, letting in natural daylight and possibly decreasing artificial lighting requirements. Newer low-e films are designed to be spectrally selective and reduce infrared heat while still allowing visible light to pass through. Studies show that providing tenants and occupants with exposure to daylight can improve productivity, reduce absenteeism, diminish health complaints, and increase test scores.
Preservation of Views
Because window shades must be closed in order to work, they inherently block views to nature and outdoor scenery. Window film allows tenants and occupants to enjoy outdoor views while minimizing glare or solar heat gain. One study found that employees with views of nature were more satisfied at work and had more patience, less frustration, and fewer health problems. Another study notes that not having access to outdoor views is associated with higher tension and anxiety levels in office environments.

The sun offers many benefits, such as increased productivity and reduced reliance on electric lighting; but the sun’s UV rays can also damage skin and building assets if they’re not controlled.
UV rays can penetrate windows in commercial buildings, and homes which exposes occupants to radiation. This exposure is cumulative, so the total damage an occupant receives is directly related to how often they’re exposed to UV rays.
According to the Skin Cancer Foundation, UV radiation wavelengths are classified as UVA, UVB, or UVC. Most UVC is absorbed by the ozone layer and doesn’t reach the earth; both UVA and UVB, however, penetrate the atmosphere and play an important role in skin conditions.
“UVA rays penetrate deep into the skin and can silently accelerate the aging process, cause wrinkles, and even cause skin cancer,” says Dr. Dee Anna Glaser, vice-chair of the dermatology department at St. Louis University. Unlike UVB rays, which produce immediate effects like blistering and burns, UVA rays do long-term damage that isn’t always noticeable. “Many people don’t realize that their skin is getting damaged from sitting near windows at their desks at work,” says Dr. Glaser.
UV rays can also fade furniture, wallcoverings, artwork, fabric, flooring, and merchandise in window displays.
To help raise awareness about UV rays – and how they can be safely controlled – Eastman Chemical Company, manufacturer of Vista Window Film, is partnering with the Skin Cancer Foundation as part of Skin Cancer Awareness Month to provide consumer education.
As part of this initiative, Eastman is supporting The Skin Cancer Foundation’s Road to Healthy Skin Tour, presented by Rite Aid. The Tour educates the public about skin cancer prevention through sun protection, along with the need for prompt, effective treatment.
Local dermatologists conduct full-body skin exams on a first-come, first-served basis in the Tour’s 38-foot RV, which contains two exam rooms. This year’s Tour began last week in Hoboken, NJ, and ends on August 30 in Redwood City, CA. The Tour will make 50 stops along the way at Rite Aid stores.
Window film is one of the easiest ways to mitigate UV ray damage. It can block up to 99.9% of harmful UV rays while offering unobstructed views, allowing natural daylight inside to decrease electric lighting requirements. Window films also reduce solar heat gain, which may lower cooling costs. Newer low-e window films offer year-round HVAC savings by helping keep radiant heat inside in the winter and outside in the summer.
Blocks up to 99.9% Ultraviolet Rays.
Did you know that window film can help provide sun protection for your skin and interior furnishings? Most people do not realize that harmful UV rays can pass through glass. The deep-penetrating Ultraviolet A (UVA) rays in particular can reach you behind a glass window or door in your home or office.
UVA rays account for 90% of the sun's most damaging rays. UVA rays streaming through glass not only can damage your skin and may contribute to wrinkles, photo damage, or worse, cancers of the skin, they also adversely affect fabrics and furnishings.
With one out of five Americans diagnosed with skin cancer, who wants to take a chance? Now you don't have to. Vista™ window film for sun protection with UVShield™ technology was made specifically for indoor sun protection. It is a microthin, clear window film that distortion free so you can enjoy the view without the UV.

The issues of climate change and global warming as they relate to energy efficiency have long been topics of debate. But according to the U.S. Department of Energy’s U.S. Energy Sector Vulnerabilities to Climate Change and Extreme Weather report, changes in weather and climate are already impacting the energy sector across the country. This interactive map, put together by the U.S. Department of Energy, shows the affects of increasing temperatures, decreasing water availability, and increasing intensity and frequency of storms and flooding in the last decade.
Environmental factors – whether they involve higher solar intensity, shifts in humidity, changes in the form and intensity of precipitation, changes in seasonal temperature ranges, or increased frequency and longevity of heat waves and cold snaps – all have a direct impact on energy efficiency and the building envelope, indoor air quality and sick building syndrome, HVAC usage, and equipment lifecycle. Check out these interesting facts:
When you think about ways to add a layer of security to your building, window film may not be what first comes to mind. Video surveillance and access control can only provide so much protection; by investing in window film, commercial building owners can provide additional protection for tenants and occupants.
Protective window film – or window film with safety features – can help provide a barrier that holds glass in place upon impact.Instead of sending dangerous shards flying into the air, security window film can help hold glass in place to offer additional protection to people inside who otherwise could be seriously injured from broken glass or glass shards.
After the Newton, CT, tragedy in 2012, administration at Sandhills Children’s Center in Rockingham, NC, set out to make some big changes regarding their own building security. The security project started with establishing standardized lockdown procedures, but it was soon decided that this process alone wouldn’t be sufficient.
Sandhills Children’s Center decided to also invest in window film as an added security measure. By installing security film on all existing exterior windows, people outside the building were generally not able to see in (but occupants inside the building, including staff, can still see through the windows to monitor what’s happening outside). Window film also brought the center the added benefit of energy savings, reducing solar heat gain and helping keep HVAC costs and runtimes under control.
Now Sandhills Children’s Center staff can keep an eye on activities outside the building with less glare or other distractions. Children and staff are also protected from glass breakage, whether it’s due to forced entry, high winds, explosions, or objects being thrown at the window. Building assets are also protected; they will be less likely to be exposed to outdoor elements like they would be if glass broke upon impact. The window film also protects assets and occupants from harmful UV rays from the sun.
