Insulation on upgraded old house

    I have a spec from an engineer of insulation materials that have gone into upgrading an old house. The upgrade was done in 2001.

    The details are a bit sketchy and I am wondering where to find the thermal res/u-values for the following -

    Floors

    100mm rockwool between the floor joists (doesnt specify what type of rockwool)

    100mm aeroboard floor slab (no brand mentioned)

    Walls

    50mm high density shelter board slab drylining on the perimeter walls.
    (similar to high density EPS slab is it?)


    Should I write back and look for more details so that I can determine the u-values or is there enough to work with here?

    Any help appreciated. My background is plumbing so I am out of my comfort zone a bit here.

    Eh, Rockwool you would need to know if its batts or quilt, if that info isnt there, you have to assume the worst so it would be quilt, but see if they know.

    Aeroboard is (or should be) the brand so thats 0.035 both from TGDL 2008. Insulation manufacturers often declare U or R values on their sites.

    Shelterboard, I just dont know.
