FAQ

▍Q:Is 5% VLT legal for all car windows, and what should I tell my customers?

A: 5% VLT is a “limo tint” level — only 5% of visible light passes through. Legality varies by state and country. Some regions allow 5% on rear side windows and rear windshields, while front side windows usually require 35% VLT or higher. As a Window Tint manufacturer, KOOFILM recommends positioning KHSP0595 primarily for rear windows and privacy-focused applications. Always confirm local regulations before installation, and advise customers about reduced nighttime visibility.

▍Q: How does the KHSP0595 sputtering film compare to ceramic films in heat rejection and signal interference?

A: KHSP0595 is a sputtering film with 95% IRR and 99% UVR — placing it at the high end of the window film category. Compared to pure ceramic films, sputtering films typically offer stronger heat rejection and reflectivity, but may have a subtle metallic sheen and, in some formulations, can interfere with GPS or mobile signals. As a car window film factory, KOOFILM engineered KHSP0595 to balance maximum heat rejection with signal-friendly performance. For vehicles with sensitive electronics, test on a small area first.

▍Q: What are the sample, MOQ, lead time, and pricing terms?

A: KOOFILM supports free A4 samples for quality testing. The standard roll size is 1.52m × 30m, and the trial MOQ is typically 1 roll — ideal for evaluating installation behavior, clarity, and shrink performance before scaling up. Lead time is generally 7–15 days for standard orders. Wholesale pricing is tiered by volume; OEM/private-label MOQs are separate and confirmed with the sales team.

▍Q: What customization and support does KOOFILM offer for private-label brands?

A: KOOFILM offers custom packaging, private labeling, logo printing on boxes/cores/warranty cards, and flexible product attribute customization. As both a Window Tint manufacturer and car window film factory, we support OEM/ODM brand clients with dedicated technical contacts, installation guidance, and marketing materials. The 10-year warranty covers manufacturing defects such as peeling, bubbling, and adhesive failure.
