Film that allows 1% UV transmission would have an SPF of 100 at 1.5% UV transmission, the SPF would be approximately 66.66 and with a UV transmission of 2%, the SPF would be 50 (Calculation must include full range of UVA and UVB radiation 290-400 nanometers*IWFA education guide). Sun protection factor numbers are officially determined according to established testing protocols. No claims can be made about actual SPF numbers without having these tests performed by a qualified laboratory.

Our professionally installed films do not cause any distortion and are virtually clear beyond the color or shade of the film. They can cut out up to 95% of annoying glare helping to reduce eyestrain and improve the comfort level in any space. Johnson Window Films are quality control tested at the factory Johnson Laminating & Coating, Inc., in Carson, California, USA for contamination, distortion, haze, mottle, heat lines and any impressions in the film that would affect the visual aesthetics. Each roll is rated for superior quality before it is delivered to JWFA. With the highest standards in the industry met, you can trust that you will receive a quality product every time.

Film that turns purple, peels off, or starts bubbling is usually an economy or low-grade window film that has often been installed incorrectly. Over time, the adhesives and dyes in a low-quality film will begin to break down. Johnson Window films are engineered with high quality fade resistant dyes and metallic layers that will not discolor. All Johnson Window films come with a comprehensive factory warranty when professionally installed.

Factory tinted glass is made by actually placing a dye in the glass. It does nothing but change the glass color in order to offer a certain level of privacy. Sometimes it is even called "privacy glass". Factory-tinted glass has limited heat rejection and, in most cases, has virtually no UVA or UVB reduction. Window film rejects up to 99% of UV radiation, not to mention its superior heat rejection and fade reducing properties. The installation of window film even on "factory tinted" glass is the only way to ensure the maximum protection for the occupants and contents of any vehicle.

An experienced professional window film installer will usually take anywhere from 2-3 for small vehicle and 3-4 hours for SUV vehicle.

Window film is always applied to the inside of the automotive glass. The outside of the window is used to cut-out the pattern.

No. The glass used in a vehicle is not the same as glass used on a property. There are major differences in how automotive and flat glass films are constructed. Automotive films are meant to absorb energy, that is why the windows get very hot and become heat radiators when a car is parked. As the vehicle drives down the road heat is pulled from the glass through a process known as convection. Buildings on the other hand are stationary and using automotive film could make the glass absorb too much heat, leading to thermal fractures and breakage. Flat glass films purge heat by reflecting energy preventing the energy/heat from being absorbed and actively reducing it.

Johnson Window Films are selling directly to customers vi our stores or via direct distributor. Professional installation requires skill and experience. The techniques and proper tools for installation are not found easily in retail stores. We stand behind our professional team and offer comprehensive warranties through the manufacturer for residential flat glass, automotive, and protective film lines.
