The WG 2500/2510 Window Protection Film provides high Radio Frequency and Infrared attenuation with high visible light transmittance and low reflectivity with minimal aesthetic impact.
The Film has been tested to ASTM F3057-14 and provides an average >40dB of attenuation from 30 MHz to 6GHz.
ASTM F3057-14 is the only test method specifically designed for the evaluation of glass, coatings, and films, with respect to Electromagnetic Shielding Effectiveness of Glazing.
This test method specifies a larger, more applicable aperture size and hundreds of test points; compared to previous test methods such as IEEE-299 and ASTM D4935 which are not applicable to glazing materials, and allow very small sample sizes and as few as 6 test points.
Film has been IR tested by 3rd party multiple independent authorities, most recently with the Bomem MB Series Spectrometer with measurements taken at 2 nm.
It has been tested from 250 nm through to 2500 nm and while it provides >50% Visible Light Transmission, it also provides< 1% transmission (over 99% rejected) from 800 nm through 2500 nm.
Safety & Glass Fragmentation
The Film meets GSA Minimum Anti-Terrorism requirements, achieving a minimum of GSA level 3b rating when applied to Y.” annealed glass, when applied to dual-pane tempered glass the test results show as high as GSA level 2 performance.
