    Hi,

    can kingspan K5 phenolic be doubled up? one of my project has spec of 100mm, but wherever I go they say minimum quantity 650m2 and only 150m2 is needed.

    Will they still have the same u-value as 100mm, if i double it up? there is no info in their product spec.

    Thanks!

    yes, providing there is no air gap between the layers.... and sealed all around the edges of the boards.
    Cheers :smile:
