What Is The Shading Coefficient In Window Film?

The shading coefficient in window film is the ratio of heat passing through a filmed window to heat passing through the clear, unfilmed glass is known as the shading coefficient. A lower value indicates better heat rejection. In addition, the film should also provide the least amount of light leakage.

When you are using window film, the shading coefficient refers to how much light is allowed to pass through the film from a light source. If a film has a high shading coefficient, it will allow less of the light source to pass through it and shine brightly in your home or office. The higher this number is, the darker your home or office will appear.

The following are a few common examples of shading coefficients and their applications:

Glass – 0.01 to 0.04 for industrial applications, 1 to 3 for residential, and 0.1 to 1 for automotive.

Plate glass – High-performance glass with a frequent, light transmission or low-emissivity coating on all surfaces designed specifically to allow fewer light leaks than standard glass and have low heat loss.

Fiberglass – A long fiberglass strip laminated with plastic shrink wrap. The fiberglass allows maximum sunlight penetration while blocking the most amount of heat during daylight hours.

Polycarbonate – A rigid plastic that is frequently used for storefronts and high-performance marine windows. Polycarbonate is ideal for use in high-traffic areas and areas where impact protection is a requirement.

Tinted window film – Tinted window film is designed to allow the maximum amount of sunlight through while providing some privacy while cutting down on heat loss during daytime hours.

Unfilmed glass – The value of 0.00 indicates there is no tinting or tint already on the glass. The higher the number, the greater the solar heat reduction performance of the window film in question.

The most popular window films are usually rated at 3/4 to 5 percent because they provide UV protection and privacy while also letting in some natural lighting.


Does Window Film Work On Textured Glass?

No, window film does not work on textured glass. Window film can only be applied to non-textured, smooth glass. The best way to get the film to adhere is to smooth down the textured glass and then apply the window film to it. Smooth out rough spots and then place a layer of plastic wrap over them.

The plastic wrap will help you have a bubble-free application so that you won’t have any issues with peeling, bubbling, and ripping as you go along with your application process. If you do not smooth out your textured glass, then the window film will not be able to work effectively and may look faded when it is done.

The best option for window film is to use a roll-up window film. The roll-up films are made of thick plastic and have no texture, which makes them ideal for applications on textured glass. It is also easier to get the stretchy vinyl to follow along the textured surface of the glass than it is with a roll-down film.

Stretchy window films are also better because they can conform more closely to the overall shape of your glass for a more seamless look.

The stretchy films provide the largest range in terms of clearness and visibility, depending on how much light you want to see through your windows at night or what level of privacy you want outside your home or office during daylight hours.

The stretchy films are thicker films than the roll-down films and may be best for people who want to keep their privacy a little more private. The stretchy films are also great for people who do not have a large amount of light coming through their windows.
