I was just thinking … 1/8'' closed cell foam is quite light for a given size, and also packs up reasonably small, at least compared to thicker closed cell foam. I've never used the stuff, but I also wonder if it might be more durable than something like the Gossamer Gear Polycro ground cloth or just painter's drop cloth from hardware stores. Of course, it would also provide a small boost in r-value.
Has anyone ever used 1/8'' closed cell foam as a groundcloth? How did you like it? Is there anywhere you can buy it in larger sizes (say, 7 ft x 3 ft) so that you can cut it down to size? Or heck, even 72 x 20 size? All I can seem to find is the Gossamer Gear pads, which are torso length.
Looking forward to some replies!
