Review Film Performance Comparison - Reflective Bronze

All the films are made in the USA, are WERS Energy Rated and have similar performance - allow 18% to 25% of the visible light to pass through the films, block 99% UV and block between 66% and 78% of the heat.

WHAT TO BUY?

Best Buy: The Suntek Infinity DS20 Bronze film has equal heat performance to the Solar Gard and Johnson Window Films (78% of the heat blocked) and a VLR of 37% but is the least expensive of the three.

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.
