    I have just bought a new house and today went up into the loft and found that there is 300mm of mineral wool insulation installed but in one area there appears to be some strange white fluff all over the insulation and the walkway. Anyone seen this before and know what it is.?

    It's ectoplasm! :)

    Actually, it might be cavity wall insulation that blown through into the loft space.

    Not a bad shout. Except for it being in the middle of the house. But cavity fill is blown in with some kinda high pressure blower I'd imagine.

    It's looks like the cavity wall insulation that new properties get injected into all external walls. If this is in your loft then there must be a gap somewhere that needs filling. On the new builds I work on the insulation is fed into holes (from the inside) drilled into the external block work under pressure. Any gaps are usually picked up at this stage. What's a concern for me is that the cavity insulation is done well in advance of any dry lining (certainly before ceilings are plasterboarded) so it could be that they forgot to do it until the last minute. Hence why it's in the loft and wasn't noticed.

    Reminds me of Arachnophobia, don't touch it in case a million and one spiders come scuttling out!
