Can Window Film reduce the heat and lower my energy costs?
A simple and commonly overlooked way to reduce the sun’s effects and to lower energy bills is to apply Solar Window Film. Window film, manufactured specifically for residential and commercial applications, is designed to block sunlight and associated heat, glare and UV rays. Very commonly, 40% of unwanted heat enters your home through the windows. Window film is applied on the inside of your windows and glass doors and can reject up to 79% of the total solar energy. An application of solar window film can typically, 6” from the glass, drop the temperature up to 18 degrees.
Can Window Film Really Reduce Sun Damage in my Home?
There are six factors that cause fading of fabrics, carpet, wood, etc.
- Ultraviolet Light
- Visible Light
- Heat and Humidity
- Chemical Vapors (including ozone)
- Age of Fabric
- Dye Fastness
Clear single pane glass (1/8″ to 1/4″) will reject 23-28% of the ultraviolet light from the sun. Insulated glass is slightly better, rejecting 36-41%. Window films installed on glass reject 99.9% of solar ultraviolet light.
No window film can eliminate fading. It can, however, offer maximum protection from fading due to solar ultraviolet light and solar heat.
Does Window Film cause seal failure and glass breakage?
Window film has never been proven to cause seal failure. Windows seals fail (foggy windows) at the same rate, whether they have window film or not, and glass breakage or thermal cracks are caused by defective windows not film. Our window film manufacturer gives a standard 5 year glass breakage and 3 year seal failure warranty on windows installed by LWT.
Do I need film if I have low-E glass?
Low-emission glass has a microscopically thin coating of metal oxide on its surface that purports to reflect heat back into the room. However, it does not block heat from entering the room by way of the sun’s radiation. It does block some percentage of UV rays, but not nearly the 99%+ that our window films block.
How do I clean my windows after they have been tinted?
After installation, you can clean your windows using any common commercial window cleaning fluid, or with vinegar and water, or soap and water. Avoid abrasive materials, and cheap paper towels (which tend to be abrasive).
What is the difference between Window Film and Solar Screens?
Window Film
- Enhances the aesthetics of your home
- Reduces more heat
- Clear views from inside
- Applied to inside of glass with limited cleaning restrictions.
- Window film provides additional safety protection by holding glass in place when broken.
- Our products are completely safe for dual-paned glass, including Low-E.
- Our product comes with a lifetime labor and materials warranty from the manufacturing.
Solar Screens
- Unattractive
- Heat reduction not what they claim.
- Distorted views from inside.
- Must be removed to clean your windows.
- Window cleaners charge extra to remove them.
- Collects dirt and debris, susceptible to damage in extreme weather.
- Their lifetime warranty is only on the screen material, not the cost to rescreen.
Are Solar Screens more effective than Window Film?
No. Solar screens get their performance by cutting visible light and absorption. Since visible light is only responsible for 44% of heat, the claim of 80% – 90% heat reduction is misleading. Further, solar screens cut at most 70% of UV light, the major cause of fading. Window film keeps out 99%+ of UV light all the time. Solar screens effectiveness varies with the angle of the sun. Window film is constantly effective regardless of the angle.
Post-Installation Cleaning Instructions
Do not clean your windows within 30 days of the installation. Waiting at least 30 days helps secure the adhesive’s curing process.
Cleaning Solutions
Most all standard cleaning solutions can be used. However the most effective and economical cleaning solution for window film is 3 drops of liquid dish soap added to 1 quart of fresh water.
Cleaning Materials
A clean, soft cloth or a clean, synthetic sponge is recommended for washing the window film, followed by another clean, soft cloth or appropriate rubber squeegee for drying. Never use abrasive materials to clean your film. Do not use bristle brushes, abrasive scrubbing sponges, cheap paper towels, or any other cleaning materials that could scratch the film. Some brands of paper towels are coarse enough to put fine scratches into the film. While these scratches might be too thin to see initially, over time they can damage the polished look of the film. Always use clean, soft, gentle materials to wash and dry your window film.
