Review Film Performance Comparison - Silver Grey

All the Leading USA Made Window Film Brands
compare major film brands

These six films are made in the USA, are WERS Energy Rated and all films have similar performance - allow 5% to 13% of the visible light to pass through the films, block 99% UV and block between 70% and 85% of the heat.

These films are primarily used in the office to control heat and glare on computer screens. This type of film can also work as a one-way mirror – mirrored on the public viewing side

WHAT TO BUY?

  • Best Buy: ASWF Illusion has the best heat performance at the lowest 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.
