Water damage repair question

[jen&john]

Hi there, I hope I am in the right place to ask this question. Hubby and I have had a 1979 Travelaire TT since late 2001. Last year, we had a leak in the roof resulting in a bit of water damage to the interior. A couple weeks ago I removed the ceiling panel and insulation from the inside. When I get around to replacing it, would it be a good idea to put in a vapor barrier (plastic sheeting) between the new insulation and new ceiling panel? (similar to house construction? ) Any hints, advice, and/or suggestions would be greatly appreciated! Thanks in advance,
Jennifer ( John's better half! )

Hello and welcome
My personal opinion is "not" to install a vapor barrier.Build up of moisture would actually be detrimental. Good luck--and hope to see finishing pictures,soon.

Welcome Jen & John to the Vintage RV thread. I'm glad you found us. Frankly I'm not sure if an interior vapor barrier would be a benefit or not. Perhaps you could ask a local insulating firm for guidance. Let us know what you find out. Happy Easter!

Jennifer, when you removed the damaged ceiling did it have a vapor barrier with the insulation that you removed? Did the panelling have a vapor barrier glued to it? I would use insulation with with a vapor barrier, tin foil, the thickness between roof an your ceiling panel. The thickness shouldn't be forced in between this space but use as thick as you can for insulation value. The barrier will keep the heat in your TT an protect insulation, from getting wet, by condensation off roof interior. Moisture in your trailer from cooking an showers would be removed by fan or open vent. When I replaced ceiling in my son's slide-in this is what we did,there was a paper barrier in the ceiling of his slide-in. This was a old an abused, an rewired slide-in. There was not much room in his ceiling for thick insulation but what we did worked out very well. Have fun with your project it will always be useful if you ever get a MH. ----"007"

.....use polyisocynate foam board and spray can foam to hold it into place and you won't have a problem....I guar-and-tee it!...geof kaye
