Flooring underlayment foam
I got a free partial roll of wood flooring underlayment foam recently from my son-in-law. Anyone ever use this stuff??It's 3/16" thick and is light green CFC. I got it for adding insulation to the torso area of my Thermarest Prolite if I felt the temps could be in the 20s F. or lower.For winter camping it could easily be used beneath a tent floor for better insulation of the entire floor.
Eric - can you please weigh some of that stuff and post results?
I have about 400" on roll of 42" wide, aluminized mylar on one side, PE foam, ~1/16 in thick.Weighs 33 oz, so about 2.6 oz/sqyd.I've used it to line a cooler with dry ice in the bottom.Helps the dry ice last a lot longer.
It has been talked about at Hammock Forums where it may be the same foam as used in Insultex. I've paid little attention to those discussions, having no interest in the VBL property of Insultex. One early Insultex adopter has changed to just using bare foam (no scrim) to save cost and weight since his finished insulation products will always be enclosed in nylon fabrics for durability. Note that may or may not be the same foam as yours.Per Hammock Forums posters, Insultex has a range of appropriate temperatures where the VBL condensation is manageable.The floor foam is available at home improvement stores but only in large quantities.
