Hello and greetings.
I never really paid much attention but recently I discovered just how hot our tinted back windows get from the sun. Even on moderate days, the inside of the coach heats up rather quickly once the sun hits those windows, especially if they are closed and there's little ventilation. This is fine on cooler days, but on warm and humid summer days it makes the inside of the coach heat up pretty good, despite its foam insulation on the outer panels. Closing the curtains helps a little, but the heat still gets through pretty easily.
Has anybody found effective ways to deal with the window heat? I'd rather avoid doing something drastic like window tinting, etc. I've started looking for ideas, but curious if there are some good options out there that would help, that are simple.
As always, thank you for the feedback.
Chris

I got a rear window shade screen from:

I had to install some snaps to fasten it to the coach with, but it is effective, as is the one for the front windshield.

Get an emergency mylar blanket from the dollar store and clip it to the curtain rail. Easy to store after use too.

Thank you for the replies. Some great ideas that I will try out when we have time, probably the more simple ones like the reflective material to start with and see how it works. Much appreciated!!

I have had plenty of time with my coach out of service all these years, to play with the suns heating problem on the glass.
I saw your comment on the foam backed panels, if your coach is OEM you may not have much foam insulation at all.
If you took the coach apart and re-insulated yourself, I regress.
The obvious way to avoid the sun and not use Tint, (You really need to look up Ceramic Tints for heat reduction)
is shade.
Parking under trees is effective but the chance you can do this is hit or miss.
ONE VERY EFFECTIVE WAY is to make an outside shade out of those "space blankets", those mirror like blanket made on thin plastic.
You connect to the gutter, and bring it down, pull out about a foot or two from the bottom of the window outward, and tie off.
The reflective material is crazy effective. In fact, if you stand in front of the reflected sun beam, you will feel the heat. I think you could
cook food in front of it, it is that hot.
The next way that works fairly well, is to get some of that scrim they put on fencing or stages. A heavy poly weave, comes in variety of colors.
Do the same thing as the reflective material, hook it to the gutter and let it hang. tie it out about from the bottom of the window about a foot or two. It is not as effective as the reflective "space blankets" but it cuts a great deal of the heat.
I have the honey comb blinds with the encapsulated ends inside that is supposed to stop the heat or cold. That is Marginally effective and you still get hot.
If you have an awning to cast shade on the side of the RV, that is very good too.
One warning about those expensive front windshields. DO NOT PUT THOSE DASH PROTECTORS up on the glass on the dash. it will collect heat and crack the windshiled.
ASK ME HOW I KNOW!!!!
buy or make one of those sun blockers, made from the scrim usually and tie it to the outside of the windshield (OVER THE WINDSHIELD GLASS) to block the sun. Again, the scrim is not the best but it is far better than nothing and wont damage the windshield glass.
These are some easy methods that i had played with and sometimes use.
The "space Blankets" need to be reinforced a little as it is rather fragile. I run a cord "line" along the edge, fold the edge over and use almunium duct tape to tape it for more strength and prevent ripping.
The space blanket material will last a season, maybe longer if you take care of it and is the most effective I had found to use.
