Teardrops n Tiny Travel Trailers

Has anyone thought about the foil backed bubble insulation? A friend of mine used it on his TD and it really worked well. Plus it has an 8.3 R-value, which seems much higher than any of the rigid foam board products I've seen.

There have been many previous discussions with regard to foil insulation. You might want to use the search function to find the threads.

If you are talking about the stuff called "reflectix", I used it last year in my pop up camper and it worked well. I cut it the size of my windows, and inserted it, to keep some of the heat out of the camper. At night, I would remove some of it to have the air come in, you could really feel the heat on the other side. It was also effective n keeping out some of the noise, and in darkening the camper. I will probably use it in my trailer this year also.

I used it on my galley hatch. Sure made a big difference. Be sure to read all the directions to get the full benefit.

I used the bubble insulation. Seems to be working fine. I did tape all the edges with that AC duct metal tape to seal it all up.

Looks very nice Victor!

I always thought foil/bubble/foil to be a good choice. Do you need much air space behind it when in walls to get the 8+ R value?

Thanks Steve. I just used the bubble in the roof. My side walls are plywood.

That's what's going in my next one.

I would use it but I would spend all my time popping the bubbles - doesn't take much to amuse me!

I think its an air space equal to the thickness of the product. At least that's what it is with foil foam (I cant spell polyisocyanurate).

I put 3 layers of the foil bubbles in the roof of mine. Not sure that left any measurable dead air space but I do know my AC unit can bring the temp inside down from hot to cold in a very short time and hold it there for a good while. I'm satisfied with the level of insulation, whatever the R value (aren't R's for pirates??). The walls are insulated with the pink foam insulation, didn't go for the foil till I tried to bend that foam around the front of the trailer....

These comments make me happy! I picked up two 5'x100' rolls for $35 apiece at auction. Glad to know it's a good direction on the tear. Woo hoo!

it will work some -- there are probably better way to insulate though -- especially I thought someone said it was also a little expensive.

I thought it was working quite well myself. But then that's just based on my practical experience with an actual trailer which is insulated with the material in question.

Sounds like a wonderful deal to me.
