too insulated?

[OutOutLetItAllOut]

we have, loft, cavity call insulation and double glazing..
just been in the loft and it is dripping.
not in 1 place, but all bloomin over, in a staight line, done some reading, seems like it is condensation.
anyone have any ideas how to fix it?

We had a dehumidifier after our place flooded once.

But how is the humidity getting up into your loft? Is it sealed off from the rest of your house?

The eaves of the roof space should be open to the outside - they haven't been stuffed with insulation have they?

I am interested in this one as was going to have the loft insulated and then heard stories about people struggling with damp in their homes after having cavity wall/loft insulation work done.... so put off the job. been regretting it now with the cold weather so would be interested to hear peoples thoughts on this.

At a guess would say the eaves have been blocked with insulation you need to leave a gap to allow air to circulate. I'd speak to your installer.

I agree with Mimsy - how is humidity getting in to your loft? When I open mine up, it's usually cold up there...but dry. You can get roof tiles that are ventilators, we had a few fitted when we had a new roof at our last house, and that helped make sure the loft had a bit of air flow.
My problem is condensation in the rest of the house!!

From memory (of hearing dh waffling on) I think the problem is something to do with the eaves being blocked, as you still need to have ventilation of some sort.

So I guess the answer to your title is, you can't be overinsulated, but you can be insulated incorrectly.

If a company done this for you, call them and get them to sort it.
