Best way to keep the sun's heat from the front away ?

Hi, I had the same problem in that situation. I have the exterior shades that snap in place, although mine use the velcro fastners. I went the Home depot and bought a couple of rolls of the foil and foam insulation - it is only about 1/8 inch thick with foil on both sides and foam in the middle. I tried just cutting it and placing on the inside but could not get it to stay in place for any length of time. Sooo I took my exterior shades and some new rolls of foam to a local business that makes boat canvasas and had him sew the insulation to the back side of the exterior shades. It made an unbelievable difference. I can even turn my front ac off at times. Most anyone with a big sewing machine could do it. Nothing fancy, just stitched all the way around one time. Hope this helps. It sure worked for me.

Hi,

Reflective covers on the outside. Use an air gap between the cover and the rv, if it is possible.

We had shades made that snap on to the outside of the coach and cover the windows. I've considered using bubble wrap between the cover and the glass to insulate the glass. Obviously, bobble wrap on the inside might cause the glass to overheat and discolor the plastic film between the glass, so don't do that.

Some friends have used tin foil on the inside of the windows. I'm not so sure that's a good idea since the heat buildup could damage plastic film between the glass as discussed above. Tin foil on the outside would work but sure would look trashy.
