Do any of your Premium Films show an iridescent (rainbow effect) to the interior side of the glass?

No, our select films will not do this. Ask for your free installation sample when making your consultation with us to ensure you will be completely happy with our selections. Some newer films on the market in fact do have these inherited iridescent aesthetics that are not visible until after the film has been installed to the glass. We recommend you always ask for a free sample installation to be sure! Florescent lighting can enhance the rainbow effect.

What about nighttime privacy?

There is no such film that can block the view from the exterior during nighttime while allowing you to see out. Daytime privacy films can be considered to be, Medium to Very Dark or Reflective which you can see through while inside the room. Frost films allow the light to transmit through it, but you cannot see in or out from the inside or from the outside/exterior back into the room. Opaque/Blackout or Whiteout Films block out 100% of the light, allowing absolutely no light into or out of a room. Solar window films are designed to see through, while Frost, Blackout, Whiteout and decorative films are designed for interior and exterior privacy glass from both the interior and exterior of a room.

Where is window film applied?

All films except for extremely rare circumstances are applied on the interior surface of the glass. Exterior films are applied for two reasons.

1. If for any reason a window is not accessible from the inside, an exterior window film would then be your only option unless the glass is pulled out from the frame.
2. Two, you are applying graffiti film. Graffiti films are thick clear films applied on the exterior surface of glass, mirrors and even elevator doors designed to protect the surface from accidental and (or) malicious behavior. This saves you from having to replace the damaged surface.

What to expect at installation .

1. The installer(s) will survey the window area and place a drop cloth down to protect the area where the window film will be applied.


2. Next, the installer(s) will thoroughly clean the interior of the glass with a biodegradable soapy water solution that does not have a scent. The installer(s) will clean the glass with a sponge and use a commercial razor blade scraper to clean any particles that may not have been removed by the sponge.


3. The installer(s) will spray the glass down and apply the pre-cut piece of film that has been custom cut for that window. The window film will then be applied to your glass and the installer(s) will pull the plastic liner off of the back in order for the adhesive to be activated by the water solution. The installer(s) will then apply pressure to the center of the glass with their hands and their squeegee, and work the moisture out to the edges in order to secure the film to the glass. If necessary, the installer(s) will trim the edge to fit, customizing your window film to the glass for a perfect fit. The window film will have a 1/8 inch border or less around the frame of your glass as recommended by the manufacturer. After the window film has been applied to your glass, expect a drying time for complete water evaporation of 30 to 90 days.

How are window films made?

Window film products are the result of a very sophisticated manufacturing process using only the finest raw materials and state-of-the-art manufacturing technology. Transparent layers of high quality polyester are laminated and coated using special adhesives, ultraviolet inhibitors and protective scratch resistant coatings. Select concentrations of metal particles (or ceramic particles) are sputter coated onto sheets of polyester, allowing for varying degrees of color and solar energy rejection performance capability. The result is the finest quality window film products in the world.

What are some of the benefits window film has to offer?

Window film can reject up to 82% of the sun's solar energy and block out 99.9% of harmful and damaging Ultraviolet Rays. Here are some additional benefits that you may also experience after an installation:

• Reduced interior heat
• Increased fade protection
• Reduced glare
• Increased privacy
• Improved interior comfort
• Reduced utility costs
• Extended air conditioning equipment life
• Added protection from accidents, storms, earthquakes and burglars

Is window film safe for use on dual pane windows?

Yes, window films that are designed for dual pane glass do not cause seal failure or glass breakage. All of our films are safe for application to dual pane windows. When recommended films are applied to the inside pane of a window, there will be some absorption (except with clear safety films) of the sun's energy, which will increase the temperature of the glass pane. Some of this heat will transmit to the airspace, slightly raising the airspace temperature. Even a 20° F increase (unusual for most films) will result in a less than 3% change in air pressure, whereas properly made units are designed and tested to withstand 22% changes in air pressure.

Risk of seal failure is greatly determined by the quality of workmanship and the quality of materials that go into building the dual pane window. The best guard against seal failure is to purchase well-made units from reputable window manufacturers that have solid experience and histories with dual pane windows. Most films come with a standard 3 year Unit Seal Failure warranty.

Will film cause glass to break?
Glass breaks when stressed. There are five types of stress, which may cause glass breakage:

1. Thermal Stress--from absorption of solar radiation.
2. Tensile Stress--from the weight of the glass itself.
3. Mechanical Flexing Stress--from wind.
4. Impact Stress--from flying objects, hail, baseballs.
5. Twisting Stress--from building or window frame sagging or settling.

The first type, thermal stress, is the only one which film may affect. The use of window films will increase the thermal stress on sunlit glass. However, there are also other factors which will increase thermal stress such as: partial shading of windows from overhangs, tightly fitting drapes or blinds, signs or decals on windows, heating and cooling vents directed at glass. In addition, different types of glass (annealed versus tempered, clear versus tinted) have different solar absorption rates and will withstand different degrees of thermal stress.

Our manufacturers have recommended film-to-glass tables for use by factory-trained dealer installers. If a consumer is ever in doubt, he/she should request a copy of such guidelines. Listed are some glass types or conditions where the use of a solar control (not clear safety) type of window film is not recommended without extreme caution.

• Any single pane glass larger than 100 square feet.
• Dual pane glass larger than 40 square feet.
• Clear glass thicker than 3/8 inch.
• Triple or quadruple pane glass.
• Window framing systems of concrete or metal that have no gaskets or seals.
• Glass where framing sealant or gaskets that are no longer resilient.
• Damaged, chipped, cracked or scratched glass.
• Round, bent, laminated, textured, or wired glass or skylights.

Will window film kill my house plants?

In most cases if a house plant is already receiving adequate light the use of window film will not harm it. New growth or flowering may be retarded, and, for a few days, a plant may go into a state of shock while it adjusts to the light change. If a particular plant normally wilts by the end of a sunny day, it will actually thrive better with film installed. Although there are some obvious guidelines in determining what, if any, effect window film will have on a plant (for instance, dark green plants need less light than lighter colored ones), there is one sample test which can be done prior to film installation: merely move the plant to an area with less sunlight for a few days. In addition, most nurseries or local agriculture agencies can advise you whether a particular plant needs closer to maximal or minimal light.

Can I apply window film to my front doors?

Yes. Every State has different laws about where window film can be applied. Please check the IWFA link for complete details.

Warranty Information

Our various window film products, manufactured by different companies, supply you with warranties that can be limited to five (5) years for specialty film applications, 15 years for traditional solar window film in commercial applications, or lifetime for solar window film in residential applications. All manufacturer warranties can be viewed by clicking on the manufacturer links which can be navigated through our site.

Huper Optik Products offer a "Premier Warranty" when applied to your home windows. Huper Optik USA will match your existing warranty put in place by your window manufacturer and will cover up to $2,000.00 per pane of glass should an invisible defect/fault exist and accelerate a glass fracture which could occur with or without window film. (It is rare that this will ever occur; there is less than a 1% chance after film application that this will occur, and may only occur when we have extreme temperature changes from hot to cold or cold to hot inside to the temperature outside of your glass)

For commercial applications, Huper Optik offers a 15 year warranty.
