Reflectix works ok, but it's CRAZY expensive, even the off-brand cheaper stuff is pretty expensive. This is what I did, and I'm not a super handy-woman either.<br><br>1) I bought 4 foot by 8 foot sheets of 3/4 inch white styrofoam with a shiny reflective side and a plasticy side. They are about 8$ for a sheet (or were when I was buying them). Mine are labeled "R-tech by Insulfoam a Carlisle company". They sell it in 1/2", 3/4" and thicker. This stuff is what is used in houses, and can buy it at Lowe's, Home Depot or any sort of building supply store. My 12' by 6' by 4' (tall) van took about 6 sheets, to do 1 layer all the way around. Ideally you want 2 or 3 layers on the ceiling, since that is where most of your heat is lost (since heat rises).<br><br>I just cut it around the larger obstacles like the wheel wells, and otherwise just shoved and pushed it into place. In a few spots I needed some "stick" I used 100% silicone sealant and duct tape. It works super fabulous, and I've happily survived 0 degree temperatures in Montana with it.<br><br>I want to add another layer or two to the ceiling, but am otherwise super happy with it.<br><br>To cover my windows, I bought felt cloth from Walmart doubled it over and sewed it together. Super warm, super great. To hold it up, I use either velcro, or just shove it in behind the white Styrofoam insulation <img src="/images/boards/smilies/smile.gif" border="0" align="absmiddle"><br><br id="tinymce" class="mceContentBody ">The "great stuff" expanding can stuff is to fill all the little cracks and crevices and stuff and the parts where you couldn't quite get covered with the white styrofoam.<br><br>I'm not saying willy's method doesn't work, but it's a fair bit of work and more expensive to buy all those bits and pieces, and requires more handy "man" skills <img src="/images/boards/smilies/smile.gif" border="0" align="absmiddle"> I do agree with him about condensation, that is definitely an issue. The white styrofoam (if you seal it with silicone along the edges, will act as a vapor barrier) But you can always do that step later (I'm still working on that part.. LOL)<br><br id="tinymce" class="mceContentBody ">Bob (the forum owner) does (and recommends) the same white styrofoam stuff that I did, but he does his install different, he puts wood strips down, and then screws the insulation into the wood strips. That's too much work and hassle for me, I just shoved it into place.<br><br>Second, I recommend getting a "Portable Buddy" heater by "Mr. Buddy" it's the medium sized one that they make. You can set it on the floor, and warm the place up in minutes. They are about $100, but are safe to use indoors, I turn mine on for a few minutes before bed, and a few minutes after I get up. makes getting out of my warm bed a lot easier, and makes changing clothes a lot nice experience!<br><br>With Love,<br>Tara
