Oh good, then you can answer my question about whether the pool noodles had any type of extra coating that the pipe insulation didn't....although I guess you did answer that by saying they were the same, but just wanted to be sure.
The only thing I'd worry about is if they use any type of sealer on the foam to make them water resistant. Hopefully that stuff isn't too flammable. and if they've been used in someones pool, what would the ramifications be if they had chlorine soaked in the material?
