How Does Window Film Work?

Window film has become a popular solution to many of the problems associated with windows. Whether it is solar heat gain, annoying sun glare or damage to flooring and furnishings, there is a window film suited to address the individual or collective needs.

When applied to the inside surface of the glass window film can create a protective barrier. Many residential and commercial window films are designed to "reflect" heat and glare. This is typically done with a very thin layer of metal applied to the film during manufacturing. The layer of metal is so thin, it will not interfere with cell signals. Typically, the more reflective the film is the greater amount of heat that is rejected. However, these films need not be "mirrored" to accomplish this.

Ceramic films are often less reflective from the outside, but do not offer the range of performance of the reflective films. Not to mention, they are often more expensive. Today's technology has created a line of films that offer low reflectivity without the expense of the high-tech ceramic films. Fact is.... there is NO ceramic in these films at all. They too are coated with an oxidized metal. Be a wise consumer and fully research these products before buying. After all, chances are you need more than just a heat shield for your windows. The heat that enters your windows consist of visible light, infra-red and UV. UV only accounts for 3% of the heat while the rest is split between light and infra-red. By doing simple math you can see that even though a film filters out 95%, 99% or even 100% of the infra-red that does not necessarily equate to higher heat reduction.

Most films provide up to 99% UV rejection. UV is one of the major cause of sun damage. This is a coating manufactured into the film specifically to block ultra violet rays.  See our previous blog about sun damage to learn more.

Glare can be reduced by using a darker shade of tint. In some cases, just being able to see the TV requires you to close blinds and shades. Our glare reducing films will limit the volume of light entering your windows making your room more comfortable.

Window films are mounted to the glass using a simple soap and water solution. A strong adhesive is applied to the film during the manufacturing. This adhesive must be optically clear and free of distortion. The "film" is typically made up a several layers of mylar polyester. Each layer plays a part in the performance of the film. Once the film has been mounted to the glass it will take a few days to dry. After the film has completed the drying process the film is now a permanent part of the glass. It can, however be removed if so desired.

Cleaning should be done only when the sun is not shining directly on the windows. It is best to avoid harsh cleaners that contain ammonia. A clean micro fiber cloth works much better than a paper towel. Squeegees may also be used. We recommend Sprayway Glass Cleaner.
