FAQ
Q: Is 4‑Mil Safety Window Film thick enough for safety protection?
A: Yes. While 4 mil is thinner than conventional security films, this film is designed to provide an added layer of glass safety by helping hold shattered glass fragments together after breakage. Its lightweight construction offers a practical balance between safety, optical clarity, solar control, and installation flexibility. For applications requiring higher levels of impact and security protection, thicker safety films such as 8 mil or 12 mil are recommended.
Q: How does the 4-Mil Safety Window Film differ from thicker safety films?
A:The 4-mil film focuses on balanced protection and high optical performance. Compared with thicker security films, it offers easier handling and installation while delivering excellent clarity, high infrared rejection, strong TSER performance, and UV protection. Thicker 8-mil and 12-mil films provide greater film mass and enhanced mechanical strength for more demanding security applications.
Q: Can you provide documents such as CoA and TDS for every order?
A: Absolutely. Since we're the manufacturer, every production batch undergoes rigorous quality assurance. We can furnish the Certificate of Analysis (CoA) and Technical Data Sheet (TDS) for each order – simply let us know.
Q: Do you accept custom orders?
A: Certainly.. We offer both OEM and ODM customization services. With our in-house R&D team, we can develop products tailored to your specific requirements - whether you provide detailed specifications, performance standards, or simply a concept, we work closely with you from formulation to finished product to bring your vision to life.
Q: What is the after‑sales procedure in case of quality‑related issues?
A: If you encounter a quality defect under proper storage, transportation, and professional installation, simply contact us with supporting evidence (photos, videos, or test reports). We guarantee a response within 24 hours and will provide a suitable solution-such as repair or replacement-upon verification.
