Apparently the hinging is similar to that used in the automotive industry. When engaged, the water proofing is literally squished to a solid connection. Your critique suggests you think of it as a camping shelter, but it doesn't seem to be intended for that use. Trailer homes, which serve more of a similar function, don't typically come with built-in curtains. It clearly is inspired by camper equipment, as are a lot of trailer homes, though. Insulation was my thought, too. It might be okay. An acquaintance of mine has a 700 sq foot yurt and it is cozy even mid-winter. Even so, it probably still leaks a lot of heat, which could be expensive in winter. It's probably similar to the experience with trailer homes, but more so because of the size.
