Clear (Untinted) Films

All the films are made in the USA and are WERS Energy Rated and have similar performance – between 64% and 77% of the Visible Light passes through the films, blocking 99% UV and between 36% and 58% of the heat.

The main difference between the films is in the price and in the winter heat loss performance of two films: the SolarGard EcoLux 70 and MEP Enerlogic 70. While all the films in the comparison reduce heat loss through the glass in winter, these two films achieve a much lower U-value (better) than the other films, although the substantial price premium is noted.

WHAT TO BUY?

  • Best for heat:Smart Films ClearView ICE 60 blocks 58% and a VLR of only 16%.
  • Heat and Light Balanced:SolarGard LX70 blocks 55% and has a VLR of 9%.
  •  Good heat reduction and low reflection:Smart Films ClearView ICE 70 has similar reflectivity (10%) to the SolarGard LX70 and blocks 50% of the heat at a lower cost

NOTES: The performance data shown above is taken from data published on each company website and published company literature. The data is presented to assist consumers for comparison purposes only. The data and trademarks remain the property of their owners.

  1. WERS – Window Energy Rating Scheme – Film performance data has been independently tested and verified as true (no point in comparing performance if the data for a film has not been confirmed to be true)
  2. VLT – Visible Light Transmitted (less than 20% VLT will make a room “feel” darker)
  3. VLR - Visible Light Reflectance (a measure of how “shiny” or “mirrored” the window appears – clear glass has a VLR of about 8%. As VLR increased above 8% the window appears more reflective
  4. TSER – Total Solar Energy Rejected (indicates the films heat rejecting ability – more is better to reduce heat)
  5. SHGC – Sikar Heat Gain Coefficient (a value ranging from 1.00 to 0.00 showing the solar heat that is transmitted through the glass – lower is better)
  6. UV – Ultra Violet light (the major cause of sun damage and fading – more blocked is better to reduce fading)
  7. U value - a measure of how effective a material is as an insulator. The lower the U-value, the better.
