Due to the weird shape of the Newmar windshield, 48" material isn't deep enough so I need to either join 2 pieces together or find something wider than 48"
Also it needs to be close to or in contact with the window to avoid heat build up. So window drapes or MC won't work as the Newmar has a sloping front window - the bottom of the shades is 18" away from the window. The build up of heat in that space is very high as was pointed out.
I wonder if I can get 60" wide bubble insulation?
