    Morning all,
    Am putting a lean-to on the side of a property and bought Corrapol clear flashing (PVC) and Corrapol clear sheeting (Polycarbonate). Both specced as 95mm pitch between peaks of the corrugation. The flashing is all the same, about 92.5mm and the sheets are all the same, about 96.5mm pitch. It doesn't fit, it's not even close... am I missing something fundamental or has someone had this problem before? Have emailed Corrapol / ClearAmber with no reponse yet.
    Cheers, Dave

    Update : Clear Amber have sent a reply - the flashing strip is supposed to measure up short, it spreads a bit when it is deformed (by the pressure from sheets on one side and the wall on the other) so that it fits. It doesn't seem to (it could be just me) but it looks like I'm going to have to just make it fit somehow.
