Ceramic IM70

The Ceramic IM70 from 3M offers a solid choice for those looking to manage cabin heat without compromising on light visibility, thanks to its nano-ceramic construction. It blocks 40% of the sun's total heat energy, which is decent for a light film, though not the top performer in its class. This film also provides reliable UV protection, blocking 99% of harmful rays, and ensures your devices stay connected with confirmed signal safety. While it does cut glare by 16%, you might notice some dashboard reflection, especially at night. Every cited spec above links straight to 3M's own document — worth a look before you decide.

A light, clear-view film for hatchback side and rear glass: 40% total solar energy rejection and 60% infrared rejection in a metal-free film that leaves GPS, FASTag and phone signal alone, plus 99% UV rejection to help protect the cabin from fading.

Most cabin heat arrives as infrared and visible light. Ceramic IM films use nano-ceramic particles, not metal, to reject infrared: 60% IRR (measured on the film alone) at 75% VLT. TSER, 40% here, is the broader figure: it counts the whole solar spectrum and is measured on glass, so real cars differ a little. A lighter film always rejects less total heat than a darker one, and the IM range trades heat rejection for clarity — IM70 sits at the clear end. Because the film is metal-free it does not interfere with GPS, FASTag or mobile signal.

It is the lightest tier, so heat rejection is modest: 40% TSER, lower than the darker IM tiers, and it gives little privacy. Choose a darker IM tier if heat or privacy is the priority. Tint limits vary by state, so check current rules before choosing a level.

Have it fitted by a professional installer — 3M specifies wet application only. Clean with a neutral, abrasive-free glass cleaner and a soft cloth, and avoid sticking tapes, suction cups or stickers on the film.
