I will try my hardest to remember to take a picture for you. I am really happy with how they did this for us, wasn't cheap (500ish), but works awesome and they have a five year warranty replacement no matter what, can't beat that.
As far as privacy, they have different colors, but we got a light tan color that works with out interior, but you can't see through it at all. Heat, well, keeping it in or out, not really anything going to help with that...
pdecat, I have scowered the net and can't seem to find a link to show you... I will keep looking. I have the original receipt on the boat, I will try and look at that and see if it has the name of them, that will help.
FYI, we have 1986 Mariner. The tracks run vertically along the left and right side. We have 2 sections for it, one main and one smaller one on the side (pictures will show better what I mean). The door on the Mariner is not perfectly square, so it doesn't fit across the top perfectly, but about 4 inches short across the top, but you really don't notice it. I wil get some pictures and it will make more sense.
