What's the story on Dow's SafeTouch polyester insulation ?
How's it compare to fiberglass and cellulose ?
Would you use a vapor barrier with it for western Arkansas climate ?
If so, which side should the barrier face for this climate ?
I have not used it yet. Compare the density before installing in attic or walls; Dow SafeTouch Insulation
Work the numbers; divide the thickness by 12, times the square footage. Weight divided by the previous product for the density per cubic foot. R-21 = 1.05, R-19 = .65, what did you get for R-30?
If any ads are present below my answer or words underlined/colored, I do not condone/support/use the product or services listed/linked to, they are there without my consent.
WELCOME to the forums, if I forgot to say it!
