I’ve posted this before but it’s worth repeating. The MY sunroof is very good at blocking IR radiation but one needs to realize there are 2 ways to block radiation: reflection and absorption. The MY sunroof seems to absorb quite a bit of the IR radiation which is significant because it causes the glass to heat up and essentially become a radiator. The best way to prove this to yourself is to put your hand on the glass on a sunny day.
You can mitigate this by either putting a film that helps reflect IR radiation or a sunscreen on the inside. The screen will block the radiant effect of the glass as well as create an insulating layer of air between the glass and the screen.
The sunroof makes a wonderfully open interior but even with coatings glass is a horrible insulator. This is why most companies provide some sort of shade or screen for sunroofs in cars.
