Browse Forums General Discussion 1 Nov 17, 2008 2:14 pm Hi,
I have emptied my shed to begin lining and insulating it. The first thing I have done is lined the interior walls and ceiling with thin clear plastic. The second thing is that I have put in insulation bats and then the third is put on the gyprock. I have lined and insulated both side walls and have the roof to go. A friend at work told me that due to the plastic between the shed walls and the insulation their may not be enough air circulation and I may get condensation inside. Can anyone help me with this? I don't know weather to pull the plastic off of the roof (inside) before I insulate and line that also? Thank you. Re: lining my shed 2Nov 17, 2008 6:15 pm Generally you would use sarking for the walls and anti-con for the roof. The plastic won't really do anything.

Thanks for the web page that was good information. So you dont think the plastic will cause condense and mildew? Re: lining my shed 4Nov 17, 2008 11:02 pm Ozswede So you dont think the plastic will cause condense and mildew? The science of vapour and air barriers is complex: http://www.buildingscienceconsulting.co ... efault.htm I note from your profile that you are in SA which is a temperate region. Condensation occurs when moisture contained in warm air escapes into the lining and condenses on to a cold surface. I personally wouldn't recommend plastic in the system but it depends on how you do things. More importantly be attentive to the following. The key is to prevent warm air (carrying moisture) getting into the wrong place in the first place but if it does give it at least a place to escape. The shed should be first weatherised completely i.e. seal up every crack in the outer structure with sealant. Put in your batts. I would suggest sisalation as well but the shiny side needs an air gap to work. When you line the shed with gyprock make sure that you plaster it completely so there are no gaps either. Gyprock can at least allow the interior wall assembly to breathe if moisture gets trapped in the cavity. Don't paint it with non-breathable latex. IF you are running air con in the shed make sure that hot moist air can't enter via the door or window frames. Hi, I am sheeting the inside of a 5.7 x 8m shed with gyprock.
