Question:

will cellotex insulation sweat behind a shower?

My builders blocked up a doorway with plasterboard and cellotex insulation behindThe wall was plastered and then tiled to form part of the showerA year on, the tiles are coming away from the wall.On investigating i found the plaster and plaster board to be soaking wet and the cellotex appears to be sweatingWould i be better to remove it all and fill the space with ordinary fibre glass?

Answer:

Whole grain cereals from Kashi are really goodLook at the nutrition labels for foods with 6 grams of fiber or moreLots of good choices among fruits and vegetablesThe less processing, the more fiber.
The insulation isn't your problem: 1NEVER, NEVER, NEVER use drywall (plasterboard) around a showerIt's not waterproofUse Hardy-board or some other cement boardCement board can take the moisturedrywall can'tThat simple2Your builder didn't install a vapor barrierA simple sheet of plastic between the wall board and the wall properSounds like your builder got cheap (as so many of them do nowadays.) You can sue (and wait for the courts) or you can have it redone correctly(I would do both.) There really isn't a repair for shoddy original work.
