    Went to Lowes and saw a few different types of Roxul what is best to seal a fireplace damper and tip of chimney for a insert install? I saw Roxul R30 comfort batt i believe at lowes and safe and sound R15.

    Only difference should be the thickness. Just depends on which way you want to shove it in there.

    Yup. You are gonna be packing it in. R value means nothing in that context.

    I installed quite a bit above the stove then placed my homemade block off plate. I chose the thinnest Roxul they had (3.5 inch) so it would be easier cut and stuff up there.
