What Is
Refleshine Solar Film?

  • Refleshine Solar Film is a Japanese window film developed by Sumitomo Riko. It uses a spectrally selective optical layer designed to allow visible daylight to pass through while reducing ultraviolet and infrared heat.
  • This means rooms remain bright while helping to reduce solar heat buildup.
  • One unique feature often highlighted about Refleshine is its ability to reflect far-infrared heat energy. This allows the film not only to reduce heat from sunlight but also help reflect indoor heat back into the room, which may improve overall thermal comfort.
  • Because of this technology, Refleshine is often marketed as a film that helps with both cooling and heat retention.
  • However, depending on lighting conditions and glass type, the film may appear slightly more reflective from the outside, especially compared to ultra-low-reflective films.
  • Include in may affect wifi/signal problems. Focus on heat reflecting technology.

What Is
3M Prestige 70?

3M Prestige 70 is one of the most well-known premium solar films produced by 3M. It uses a multi-layer optical film technology rather than traditional metallic coatings.

This allows the film to reject heat while maintaining a very clear and natural glass appearance.

Prestige 70 is widely used in residential homes and commercial buildings because it provides:

  • High visible light transmission
  • Strong infrared heat rejection
  • Very low interior and exterior reflectivity
  • Up to 99.9% UV protection

Because the film is non-metallic, it also does not interfere with signals such as WiFi, mobile networks, or GPS.

Compare Both Specs
Heat Rejection

Both films aim to reduce solar heat entering the building.

3M Prestige films are widely recognised for their strong infrared heat rejection, helping reduce indoor heat while maintaining a clear appearance.

Refleshine uses a different optical design that helps reflect and absorb solar energy, helping reduce heat buildup in rooms exposed to direct sunlight.

In real installations, both films can noticeably reduce the feeling of heat near windows.

Summary

Both films offer strong heat reduction

Performance differences depend on window orientation, glass type and room conditions
