Insulating Ceilings and Wall
Posted: Sat Oct 08, 2016 10:30 pm
I have an older 14x70 that is used as a hunting and fishing cabin in northern Illinois. I currently do not have any leaks but decided to update the ceilings and wall panels in one of the bedrooms and while I was at it I removed the insulation. The walls had very thin unfaced insulation between the studs with no vaper barrier. The ceiling from bottom to top was ceiling panel, thin unfaced insulation between the wood trusses. wood trusses, vapor barrier, thin unfaced insulation and finally metal roof. I can't get insulation and vapor barrier between the trusses and metal roof so wondering the proper way to insulate the walls and ceilings. I read some posts here that indicated the insulation should not touch the metal roof or it will cause condensation which to me seems impossible and also that was how it came from the factory. Looking for any advice but specifically have the following questions:
Should I use unfaced insulation on both walls and ceilings like they did at the factory or should I use faced insulation? Do I use a vapor barrier regardless of whether I use faced or unfaced insulation?
Just a bit more information. The day I did the demolition it was warm and poured rain. The next day there was not a drop of water inside so I feel good there are no leaks. The next night was cool and I turned the furnace on. In the morning I checked the room and it was like a rain forest with all the condensation on the ceiling and walls. I assume once I get the insulation and vapor barrier in the condensation will go away, right?
Thanks,
Jerry
