I've bought polycryo as window or patio-door insulation kits from Amazon or Walmart. I believe that the larger door insulation kits may actually use a thicker gauge polycryo, if you're concerned about puncture resistance. The stuff is pretty durable for the extremely light weight and compactness. I've also recently used the SOL emergency blanket, which also comes in an XL size. The 1/8" evazote foam pads are also good multi-purpose items that can be used as both a sit pad and a ground sheet that provides a bit of insulation. I haven't used Tyvek, but I'm sure that it has a purpose in the quiver. There is a lighter version of Tyvek that is used for kite making.
