No fastening required. It just tucks up a few inches all the way around underneath the fiberglass. After you put it on, go to both rear corners and give it a tug to snug things up. You'll have extra from the roll to make an insert for the rear portion, and even some rectangles for the interior windows if you want. Just measure the length of rear to front x 2, add the width of the front canvas and that gives you total length. Cut this from the roll. Measure the height at the rear and the front and (starting at one end 1st) mark these points on your insulation. Take a long straight edge (I believe I used a straight 2x4) and connect these points which will give you the slope of your cut. Double check all measurements before you cut! Then, measure across what will be the front, and make the same marks for the other side. Once you have it accurate for the sides and front, cut your little archway where it will rest on the roof in front. Err on the side of too big...you can always cut it down a bit. Mine took about 30 minutes to make and has made cold weather camping much more enjoyable...especially when I have a kid sleeping up top. You'll be surprised how much heat it traps. Many other campers have seen mine and went "wow, I need to make one of those" and have used mine as a template. Have fun!
