Cargo trailer insulation tech

[proskier101]

I have a 7x16 trailer and want to stop some of the heat from coming in from the roof. Nothing too serious as I just want to make it more manageable to be in when it's in the sun.

I added the rolled up silver bubble stuff to my garage door and it was an incredible difference in my south facing garage.

Is rigid foam board the best option? I am in utah, no heat or cooling will be in the trailer ever. So I don't think condensation will be an issue.

M18 batteries.

Edit: Never mind, didn't realize the goal was to make it colder not hotter.

I used 1" foil backed rigid with taped seams. Works well.

This is how my SnoPro trailer is done. When I was shopping trailers is was common to find heaters in them and guys talking about sleeping in them during snowmobile trips.

Haven't been in there in the winter yet.

That's exactly what I'm thinking. Online forms talk about moisture issues behind that however I assume my use and location won't run into that.

Mine is lined as well, I have all aluminum frame, I suppose moisture could be an issue if you walls are steel, but still it would take a lot of years before it would rust through any steel support structures.

I put composite siding on the inside of mine and use it for summer camping. We'll see how moisture effects it this winter with the sleds, but I think it'll be fine.

Henry's tropi-cool for the roof

Got some in, started skinning the top with aluminum sheets too. I forgot to tape the seams but the foam boards are crammed in there tight.

I'll get an updated pic tomorrow.

The moisture would be air leakage from inner to outer of the insulation envelope right?

So interior vapor barrier would be important to help prevent the moisture?

I don't tape any of the foil faced insulation I put on.

Best to have the insulation open to the "dry" side to let moisture out. Here in Canada you put vapor barrier on the inside of the house, but I've heard a rumor that in florida you put it on the outside. Weird.

Anyway, I see lots of people here with vaporbarrier on the inside of the house reside and install foil (or tuck) taped foil backed insulation on the outside. Now they've got a mold sandwich.

For this reason I didn't well seal the ice shack I'm building. Just like my 1937 house I think it's better to have it a bit drafty then sealed up tight.

Too late now, but I just used the fiberglass faced polyiso instead of the foil and really like it. It's way tougher/stronger than the foil and much harder to damage. Also seems much more rigid.

Thinking about it, in my trailer the liner is wood, like paneling, not waterproof. I wonder if they did that so it would breathe or wick the moisture out of the walls.

If you notice too, our floor track systems are designed to drain water out the back. Mine's a SnoPro also.

Actually you are right, never thought about that. Guess I better keep them clean. LOL

I wanted to paint the floor to make it easier to clean, but is it better if it can absorb moisture? I have no idea. I do hope to haul snowmobiles in there someday as well.

I've read no paint as to not trap moisture.

Ended up ok. Not perfect but functionable. Those v nose cuts tested my geometry skills.

Looks really good

Agreed. These trailers are not square what so ever.
