Have your Rockwool bass traps/Superchunks caused damp probs?

Hi I'm in the process of moving house... from quite an old house with single solid walls to a house built in 1993 with brick cavity walls. In the old house, I had a alcove which I filled with rockwool to make a bass trap. I pulled the trap out today and found that the wall (and the cotton the RW was wrapped in) was quite black with damp. To be fair, even with nothing in that corner of the room the wall will go a little black after time - but nothing like this! I plan to build superchunk floor to ceiling traps in the new house and am a little worried that the same thing might happen. Has anyone else experienced similar problems? Am I likely to have an issue seeing as the house is newer, seems to have no issue with damp, has better heating, etc. Would appreciate any advice before I go ahead and start with the build. Cheers Max

The issue with moisture existed already as you are saying. Placing anything of an absorptive nature in front and in direct contact with it [moisture] simply allowed the material to act as a sponge or at least allowed the build up over time of the moisture. You would have to check in your new location to make certain a moisture issue does not exist already, like in your old space. If it does, then it has to be corrected first. The addition of insulation's does not create a barrier that allows vapor to cling to, so that isn't a concern specifically.
