    Hi,
    What are the avantages of using Rock Wool insulation over Glass wool(or is there any)? There doesn't seem to much in the difference in terms of U value.
    Thanks

    Rock wool has fire resistant properties and thats why its used as a fire stop above party walls etc.
    Both come in a range of u-values and the best i've seen was a glass wool product from Moy, (not their standard stuff, plus or something)

    It's difficult getting performance data on most fibrous insulations - I don't think the Moy 'super' material has an agrement certificate to confirm performance - have a look a the agrement boarfd webg site for insulation materials http://www.irishagrementboard.com

    Thanks Guys.
    Do you think that rock wool would have a higher decrement delay than glass wool?
