wet loft roll insulation - is it scrap?

[DJM]

I bought some 1140 x 5330 x 150mm rolls of loft insulation about a month ago and they have been stored in my attached and heated garage. When I came to use it I found 2 of the rolls wet at one end. In fact they are soaking in places.

I can only assume that they had been stood in water at the shed I bought them from and I didn't notice.
Obviously I stand no chance of getting a replacement due to the time lapse and no absolute evidence of my dry garage storage or their poor storage.

So the question is can I use any of it or should I just bite the bullet and dump it?

About 50cm of it's width seems completely dry but gets gradually damper until wringing wet. My gut feel is that I've been stiffed and will have to buy some more, but interested in views

take off the wrapping and let it dry out

if you unroll it wet it might not fluff up properly.

btw if wet it will be a lot heavier at one end. didn't you notice when you bought it?

Unfortunately I was in a hurry when I bought it (intended to use it that weekend, but rot issues stopped that) and was on my way home from work so not really dressed buying timber and insulation. So took the first 4 rolls and moved on and noticed nothing different.

Considering part of the wet insulation is already outside the wrapping anyway and a month on it's still wet, how long is it likely to take to dry?

the insulation I have used is not fundamentally absorbent and water drains through it easily.

Drying time - rather difficult to guess. However I don't think the fibres actually absorb the moisture and it is therefore being held between the strands by surface tension (?)

If that's true, lifting the roll off the ground ( keeping wet end down) and fixing it in that position will see a lotr of the water slowly drip out.

Maybe Wickes own brand is not as good quality as it is acting more like a sponge.

Go back to Wickes and explain the problem. Until they actually say 'no way', you're in with a chance. They know a lot of their stuff gets wet.
