Hi there! I totally get the heat struggle. Since those high-end ceramics were already mentioned, you might find LLumar IRX Series Ceramic Tint useful as a slightly more budget-friendly alternative that still offers top-tier heat rejection. Check out the "Heat Rejector" tool on some tint shop websites to compare specs. Pro tip: make sure your installer uses a "dry shrink" method on that roof to be safe—it's HUGE glass. Good luck!

Just sharing my experience: I went through this exact same headache last summer with my R1T. Living in a high-heat area, that glass roof is basically a giant radiator right above your head. While the previous reply mentioned the big names, I actually ended up going a slightly different route after talking to a high-end installer who specializes in EVs.

I was really worried about the massive windshield and the roof interfering with the driver assistance sensors, so I spent a lot of time researching the technical specs of Suntek Evolve Ceramic Window Tint. I ultimately chose it because it claims up to 94% IR rejection, and honestly, the difference was night and day. But here is the thing I learned the hard way: be careful with the roof. Some installers are hesitant to tint the panoramic glass due to heat absorption risks, but I went with a very light shade of LLumar FormulaOne Stratos Ceramic Tint up there. It has multiple layers of nano-ceramic tech that really helps with that "oven" feeling without making the cabin feel like a cave.

For the windshield, I stayed legal and went with a nearly clear Suntek CIR Ceramic Window Tint (80% VLT). It doesn't mess with visibility at night, but the reduction in dashboard heat is HUGE. Just make sure your tinter uses a rope soak to protect the electronics under the dash! I've heard horror stories about water getting into the Rivian's modules during install. It’s a bit of an investment, but it definitely keeps the AC from working overtime. Good luck!

For your situation, I would suggest looking at XPEL PRIME XR PLUS Ceramic Window Tint over the 3M Crystalline Window Tint. I've had both, but the XPEL feels more effective for that massive Rivian roof... honestly, it really helps with the AC load. That said, I'm always cautious about the windshield; I went with a very light 70% shade for safety. Definitely have a pro do the install to avoid any sensor issues. Hope this helps!

Exactly what I was thinking

Hmm, I've had a different experience. While big-name films are popular, I prioritize safety above all else. Unfortunately, some high-IR films can cause excessive heat absorption in the glass itself, which is risky for that massive panoramic roof. Honestly, I'd suggest Hüper Optik Select Drei instead. It uses multi-layer sputter technology rather than just ceramic, keeping the glass cooler to the touch. It's better for structural integrity and visibility, tbh. Good luck!
