Insulating windows

Question

I desperately need to improve my campers ability to stay cool. I know reflectex is a popular option as well as the shrink wrap option. I'm assuming the reflectex is probably a little better for summer heat applications, but i was hoping someone could share the pros and cons of one vs the other. I realize I won't be able to see out when the reflectex is up and I know the shrink wrap can't be put up and taken down like the reflectex.
Also, has anyone used automotive heat shield, such as that used in the firewall of a vehicle? Seems like this would be better than reflectex.

For Windows, I think Reflectix will do a better job and will be easier to store. It's thin and light.But, try the  automotive heat shield and let us know how it works. Maybe it will be better?

You should also consider window awnings to eliminate that hot sun shinning on them.

Reflectix works best here in S. FL. The tt walls are warmer than the Reflectix Windows.   I even use it on the trucks side window that faces the sun when parked in the drive.

Reflectix will work to stop heat but be careful with its use. I used Reflectix on the door window to stop heat and morning light. Left it there while the TT was in storage, the next time out the door window fell down about three inches. The supports that hold the window up are made of plastic and they melted.

So my suggestion is to be sure the window can take extra heat the Reflectix will add to any window. Or place the Reflectix on the outside of the window to stop heating the window and trailer up.

The custom made ones are not cheap.  I used the self install ones from https://ezsnapdirect.com/products/rv-shades/ .  They are cheaper and worked well for our travel trailer that we used a few summers in southwest Texas about an hour from Laredo.
