Evaluate a claim that a glazing contractor's proposed window film product is 'IWFA certified' and understand what that credential actually covers, including any bullet-resistance marketing claims.

Steps

1. Review iwfa.com's accreditation and standards pages to confirm the International Window Film Association (IWFA) is a nonprofit trade association offering accreditation programs for window film installers, technicians, and distributors, plus product performance/durability and flammability testing referenced by its standards
2. Confirm the one IWFA product benchmark that is consistently published: window film products meeting IWFA-referenced standards are described as blocking up to ~99% of UV radiation; treat other performance figures (e.g., specific solar heat gain reduction or visible light transmission percentages) as product-specific data to verify on that product's own test report, not as a fixed IWFA-wide benchmark
3. Check whether the specific installer/company claiming certification appears in IWFA's accreditation materials or can be confirmed by contacting IWFA directly, since the association does not publish a simple public searchable roster on its site
4. Flag and correct any marketing claim that safety or security window film is 'bulletproof' or 'bullet-resistant' — IWFA has published an explicit statement (renewed as recently as 2024) that standard safety/security film applied to ordinary glass is not bullet-resistant and that it is unaware of any film with demonstrated ballistic properties
5. Distinguish IWFA (window film specifically) from SGCC/IGCC/ANSI Z97.1/CPSC 1201 (safety glazing materials broadly) — window film retrofits do not automatically confer code-recognized 'safety glazing' status unless independently tested/labeled to meet those separate standards
