Wet loft insulation
Another unexpected problem here. Someone left a skylight window open
during heavy rain and now some of the loft insulation is very wet. Can I just bring the loft insulation into my flat for a few days to dry out? Will it have come to any harm? |

Wet loft insulation
I think I would be more concerned with the plasterboard ceiling which can start to bow and even collapse if thoroughly wet. I would remove the insulation, if it is only a small area it may not be worth waiting for it to dry out so replacement is probably easiest.

Wet loft insulation
I very much doubt it , personally, I had snow on mine due to the wrong type
of snow one year, after filling buckets with the powdered snow this left wet insulation and it dried off in situ actually. I guess there is a chance of something like mould growing but the insulation did suggest it had a fungicide coating. Brian -- -- This newsgroup posting comes to you directly from...

Well if its really that wet, but I got the impression it was only surface
wetness, not the sort that would benefit from a mangle! Brian -- -- This newsgroup posting comes to you directly from... The Sofa of Brian Gaff...

I had a dripping loft tank tap and it brought that type of ceiling down,
what a mess, bits of soggy plaster and wood all over the bedroom. Sadly it now is plasterboard, so a large pice of plastic is under the tap, just in case.

Buy some canes, normally for runner beans and lift the wet insulation up and support it on the canes at right angles to the joists so that air can circulate over and under your loft insulation. Loft insulation, unlike cavity wall batts, is not treated with water repellent so can be difficult to dry before it gets a chance to turn smelly. |

Rockwool is a common one, although there are other products that are becoming popular which are less irritating to the skin. Its quite common on older places with no sarking, for snow to get blown into the loft - often in significant quantities. Usually that would melt and dry out in time, and you would not be aware of it unless you looked in the loft for some reason. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

I only looked when I became of the rainfall in my flat :-) |

Wet loft insulation
The only reason I mentioned the damage to the plasterboard was based on my own experience after the ******s of so called roofers left the boiler flue disconnected. Although water condensed on a considerable area of the loft below the tiles only the area immediately around the flue was wet through. It was the plasterboard bellying downwards and starting to crack alerted us to the issue.
