Heat reflective film

How do heat reflective window films work?

What is the effect of heat reflective window films? Which film to choose? Eight models of different colours and with different levels of light transmission. Detailed information about heat reflective films for windows and special aspects of the use.

There are four key advantages

1 - Reflection of solar heat

Heat reflective films are covered with tiny metal particles. It provides a mirror or semi-mirror effect and helps to reflect solar heat. Some films can reflect up to 80 percent of solar heat.

Practical aspects: some films can lower the temperature in the room by 5 to 7 degrees (depending on the size of the room and the windows).

2-Reduced glare

Heat reflective films not only reflect the solar heat from windows but also darken the sunlight. Depending on the selected film, the window can be darkened by 65 or 20 percent. This reduces the intensity of the sunlight and glare, as well as softens the natural light.

3-Privacy and protection from prying eyes

One way visibility effect is the side effect of the heat reflective window films. These films have a mirror effect, but privacy depends on the direction of the light. Get more detailed information in the section one way privacy window films.

4-UV protection to avoid burnout

Heat reflective films reduce the exposure to solar radiation and protect against the exposure to UV rays. The protection level is 99 percent. The films reduce UV exposure but do not block it completely. Direct sunlight is not the only reason for film burnout. Get more detailed information in the section UV window films.

Technical features of heat reflective films

The capabilities of the films can be judged by the technical data that reflects the features of the film. There are two main factors to take into account:

  • VLT % - visual light transmission expressed in percentage;
  • Ir % - reflection of solar heat reflection expressed in percentage.

The darker the film, the greater the percentage of solar heat reflection.

Attention!! All technical data obtained under laboratory conditions may slightly differ when using films in each specific situation. The effect is influenced by the type of the glass surface and the design of the insulated glass unit.
