Review Film Performance Comparison - VLT up to 10%

All the films are made in the USA, are WERS Energy Rated and all films have similar performance - allow 6% to 10% of the visible light to pass through the films, block 99% UV and block between 62% and 75% of the heat.

WHAT TO BUY?

• Best for heat: SolarGard TrueVue 5 blocks 82% of the heat but is highly reflective externally (VLR 45%) and no more reflective than clear glass internally (8%)
• Heat and Light Balanced:SunTek Symphony SYLR 10 blocks 72% heat and external reflectivity of 15% andSmart Films Sunblock 10 is the least reflective externally (10%) and blocks 64% of the heat

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.
