what kind of Primaloft do I have on 02/20/2011 10:49:23 MST Print View

I got some Primaloft from BPL but Addie doesn't know whether it's "One" or "Sport" or what...

I weighed it - 3 oz/yd2 (23 1/8 oz for 62" x 160" = 7.6 yd2)

Loft is about 3/4 inch

I know Styrofoam is R = 2.9 for 3/4 inch and one clo = 1 R

Assuming same as Syrofoam (not that good an assumption) 2.9 clo / 3 oz / 1 yd2 = 0.96 clo/oz/yd2

primaloft.com says "One" is 0.92 clo/oz/yd2, "Sport" is 0.79 clo/oz/yd2, couple other ones are less

I must have Primaloft One?

Just looking at it it looks like just filaments, no binder, which again is "One"

If it's Primaloft One, do I need to quilt it for a sleeping bag? How far apart?

Anyone have any opinion about this?

Thanks
