Does anyone know the r value? It's the white foam 4x8x2". I bought 40 sheets for $1 a piece and thought they would be good for something.
Not sure of the r-value but should be good if you're planning on doing some stucco work.
i'm thinkin' @ r1.3-2.3, can't remember for certain.
It`s better to be silent and thought the fool; than speak and remove all doubt.
No stucco work lol, thought I might put it on my basement walls and in joist area under my bedroom that's on a crawl. I thought is was pretty low thanks.
