Trailer Insulation

[agalen]

I have a 27 foot Look that has a finished interior but no insulation. I'm curious with such small wall cavities and relatively low R value does insulating the walls and ceiling really pay off? Any advice is appreciated. Thanks!

Isn't any insulation better than none?

It helps with condensation and adds r value. Go in a trailer with no insulation in the walls or ceiling kick the heater on when it's in the teens and below and you will have condensation dripping from the ceiling and walls. With a properly Insulated trailer theres very minimal condensation. Use the thickest rigid foam that will fit in the cavity or use a 1/2 rigid foam in the walls then a radiant reflection insulation for the ceiling use the tough r style insulation or spray foam. I can heat my 8.5x24 trailer with a 18,000 btu heater in below 0 temps with it insulated this way.

Not the case with my 7x29 uninsulated Aluma. It heats up quick with very little condensation even if I run it all night.

I have yet to see a non insulated trail not condensate when its below below zero steel or aluminum or even 15 above. Put heat to steel or metal that's below 0 and your going to have condensation. You might not see it if your trailer is finished but it's there. Also you'll use a lot less propane and wont need as large of a heater with an insulated trailer.

i just had my Triton TC118 spray foamed. Hope it helps with the sweating.

What was the cost to do that?

I was quoted 700 to spray the walls and ceiling 1" thick on my 16' Triton. He also said they wouldn't fill them full, or it would be too challenging to trim the excess.

We removed the panels and put one inch foam in all the wall and 1.5" in the ceiling cavities.

No heater yet to compare.
