Flexible slab insulation

    I wouldn't have thought it was that difficult but what do I know. I have been trying to source insulation for 6x2 studs on 600mm centres and the best fit for the job will be the flexible slabs like the Earthwool Omnifit or Rockwool Flexi.

    I have tried all the online sources that I know and cannot find the size I need. At a push I can find 100mm + 50mm but surely someone on island of Ireland has the 150mm thick 600mm wide slabs?

    If anyone has any leads I would be grateful. I need about 400 sqm.

    Hi there,
    You won't find 150mm Rockwool Flexi, it just simply doesn't exist. ( 140 or 180 mm)
    http://www.rockwool.co.uk/products/rockwool-flexi/

    I would do 100mm + 50 mm definitively, it's better to put two layers anyway . ( Or 90 + 60 )

    Or Rockwool RW3 / Prorox SL930 , they have it in 75 mm ( x2 =150mm)
    Same Thermal Conductivity than the Flexi ( 0.035 W/mK ) , but more dense so better thermal shift phase. ( You'll have to cut a bit the edge, though) .
    I would avoid any material in roll or too soft : risk of sagging overtime on the top of the walls
    Try TIDL for bulk order.
