baahahaha, love the haiku and fantastic job on the camper - so cute and very impressed!
Oh my gosh, Padigm, *thank you* for your thoughtful, in-depth replies to all my questions. Helps me immensely. I will report back with my findings once I am done (may take me a few weeks, I have a 3 year old and not as much free time as I would like...)Thanks again for this great Instructable, you've made a whole lot of people's lives better!
I had been thinking of something similar to this design for rooms/doorways that are seldom used in our house. Planned layers are: window -> 2" gap -> mylar with silver facing window -> double-layered corrugate cardboard -> double-layered corrugate cardboard -> mylar with silver facing room. The idea is I would keep this up year round. In summer, the mylar would reflect sunlight back out of the house. Some questions:1) I looked at the R value of cardboard, and it seems higher than polar fleece, so hopefully this will be effective. Your thoughts? (I have done a few international moves so just happen to have double layered cardboard out the wazoo)2) Learned from your Instructable that I would need fabric around the edges to create a tight seal. Anything other words of guidance/caution?3) Brandon mentioned a cracked pane if not taken down during the day in winter, so I guess there goes my idea of keeping it up all the time, at least during the cold.4) Does the plastic sheet HAVE to go behind the first layer of polar fleece? Or would it be just as effective as long as I keep a gap between the mylar and the window? (My sills are 5" deep. I was thinking of affixing this ~2" away from the window from the top of the sill) 3) Also, is there any additional benefit in putting another mylar layer on the back, silver part facing the room, to reflect the heat of the room back and conserve even more energy? Or should I not bother?Thanks for the fantastic instructable, I am so excited to start on my project!!!!
