Certified Window Film Safety Engineer (IWFA) The IWFA examination cuts deeper than surface-level installation knowledge. Test-takers must grasp UV rejection coefficients, structural load calculations, and safety performance standards across automotive, architectural, and security applications—topics that separate practitioners from engineers. Expect rigorous problem-solving scenarios grounded in physics and building codes.
