Nano IR — Window Film Technology That Rejects Heat Without Interfering With Signals

Illustration for the article "Nano IR Technology" from the 27Speed blog archive.

Nano IR technology is an innovation in film manufacturing that blocks heat and radiation at full effectiveness, different from traditional film made using Multi-Layer Sputtering (stacked metallic layers).

The key advantage of Nano IR is that it doesn't interfere with digital signals — GPS, mobile phones, or your car's electronics — a problem some older-generation metallic film used to have. It also extends the film's lifespan, maintaining heat-rejection performance without fading or discoloring.

This technology is built on Japanese nanotechnology patents and comes with Anti-Glare properties, reducing in-cabin reflections and improving visibility even in low light.

Frequently Asked Questions

What to know before you decide

How is Nano IR film different from regular film?+

The difference is in the manufacturing process — Nano IR packs in more heat-rejecting components and doesn't interfere with electronic signals, unlike older metallic film.

Is there really film that interferes with mobile signal?+

Yes, some film types with dense metallic content can weaken signal. Nano IR was specifically designed to solve this problem.
