I've been reading steadily about using IX for underquilt insulation. It seems to me that here in Texas it would be a good three-season UQ (including winter, rather than summer) and augmenting with a PLUQ for those rare times when it dips into the 30's.
After reading MacEntyre's posts on using PPEF, I'm wondering where you find the 1/32x60" stuff without buying a 2000' roll of it for $350+. I'm aware you can get IX from DIY gear, which might be a better answer for noob thread injector users like me. I'm thinking the PPEF might be less expensive, and very slightly lighter.
I figure I need about 5-6 yards to make a three-layer UQ, but haven't found anyone on the internet offering short lengths, other than the 12" variety used for wrapping plates for shipment, or the thicker stuff used for floor underlayment.
Another quick question: in UncleClark's post above - what material is used to fill the draft collars?
