Recommendations for glass roof cover

[LLT]

Has anyone purchased a cover for their glass roof that they like? If yes, please share! Thanks!

You mean like a sun shade?

I have one of these (currently unavailable on Amazon) https://www.amazon.com/dp/B0C9LR81KL

But to be honest, I never use it. I can't tell a difference in how much the car heats up with it mounted. I don't ever really feel like the glass roof is causing much heating inside the car. And the mounting system for this shade uses little clips that are kind of a pain to mount, so I just never feel the need to use it...

I never found the need for a "cover".

Have had the car in +110 degree direct sunlight and never found much "heat" or too much sun from the glass roof. It's designed very well.

I find the opposite to be true. I live in the Reno area. I had a 2021, just got a 2025; had I placed a custom order, I would not have gotten the glass roof. I will say it's nice in winter when you do want the extra heat from the sun.

In direct sunlight, on a 100 degree day, black colored surface temps can get over 145F. A white colored surface may only be about 120 degrees. For most people scalding temp is about 140. i.e. the temp. where somethings seems too hot to touch.

A dark colored coated glass surface, on a 100 f degree day will probably be get hot as 140f or more, but that depends on the coating and how well it reflects solar heat (i.e. doesn't absorb solar energy as heat). The science/engineering of reflective glass coatings is well understood and advanced effective coatings are available but normally no coating is as good as a shield/cover that totally blocks sunlight.

When I ordered my Mach E, May of 2021 there was no available option for a roof that was not glass. While the glass roof seems to perform thermally well in summer months it does leak/transmit more heat than a metal insulated roof. Therefore on really cold days here in Minnesota, some days up to around 40% of the battery energy is consumed to maintain cabin temperature and as a result mileage range declines.

We don't see severe high ambient temps very often up here in the north and so far our experience suggests the AC capacity is adequate however the winter months require a change in performance expectations. ( i.e. when its -20F and you are going 65 to 70 mph down the road, that cold air and wind will "scrub the heat" right out of the vehicle, quickly, regardless of any coatings on the glass, it's basic thermo dynamics/physics and you cannot change the laws of physics.) A metal insulated roof is better, and I am told, is now available

So in my opinion, solar shields work in high ambient conditions, whether or not you want or need one is a personal preference based on your experience and expectations.

I hope this helps the discussion.

Good luck.

I have used this one for a year and never remove it. I live in Mesa AZ.

Easier to install with two people to avoid dropping the clips.

Many threads on this, with owners in Arizona, Florida, etc. saying no cover is needed as little heat is transferred into the vehicle.

I live in Virginia, and on a 90° day, the roof glass will burn you if touched. I installed the Ford sun shield, but it’s perforated, not solid, so I’m having ceramic tint installed next week to cut down even more on the heat. Never been a fan of sun/moon roofs, and the panoramic aspect is totally lost on the driver and front seat passenger.

While IRR glass will reflect that spectrum the sunroof will still absorb energy and radiate it away in the form of heat, both externally and internally. A cloth shade isn’t going to significantly affect that.

Don't touch it...

Thank you for your insightful and useful input on the subject.

I’m in the San Francisco area in Northern California.

I install/remove my roof shade depending on the season. Late spring, I install; Late Summer, I remove.

I definitely notice the temp difference during summer. The cabin getting hotter is my sign to do the install. ?

I live in the SF Bay Area.

I tinted my roof with 3M Crystalline

I tinted all the glass on the car with Crystalline and it definitely keeps it cooler…
