New Vapor Barrier material like Thermadrape.
This is a material I have that is somewhat similar to what the thermadrape material is made out of. This material I have is made with a non woven backing instead of the paper cellous material that is laminated on the Thermadrape material.
I have about 10 to 15 yards of this material for now it is 46" wide of the roll. Since I have no use for all of it. So I figured its worth $15/yard shipped. You can order 1 or 10 yards just $15 a yard.
I am making some videos of gear I have made with this material and show you some tricks to heat sealing this material for perfect seal instead of sewing it!
