Teardrops n Tiny Travel Trailers

I'm working on a 7x12 cargo trailer w/13.5k btu roof air. The ceiling came insulated from the factory. I'm currently insulating the walls with prodex. They claim it's R15. Seems pretty thin, I have a hard time believing it. I'm thinking of using prodex with a layer of insulation board from lowes over it. What do y'all think of the prodex? Are the claims legit? Can I getaway with just a layer of it for my walls? I'm in TX so it gets hot.

Congrats Nick

your all set, with that much insulation you should be able to freeze your Nuggets off with only a ice cube in 110 deg Texas heat.

Thanks.

I did a test using our toaster oven and a thermocouple attached to my multimeter. The toaster oven is a Cuisinart but as far as I can tell has little or no insulation and the exterior gets HOT. I insulated our WAECO refrigerator exterior with the bubble foil, mostly to reflect sun. So with a couple of scrap pieces of double bubble foil insulation and something in the oven I used the thermocouple with one layer and two. Temp difference before the plastic bubbles started melting was about 25% with one layer and 50% with two layers. Additional layers had little affect.
I do not particularly buy the Youtube demonstration, because while they discuss the why of the "system" there is no demonstration or actual testing. I spent 25+ years in QC and know how often testing can be done in a way that is totally the end product of hay through a male bovine and ASTM standards can be used to test or to BS.

I do have to admit that this insulation on my trailer is becoming

More black art - mumbo jumbo , then science .......
With my solar panels covering the roof - it keeps getting hotter & hotter inside
While at the same time shading the trailer, defies logic as all solar panels are tested at 25c
But to me it looks more like they go to 75c in bright sun light .....

It sort of makes you wonder how the hell those giant SOLAR fields of panels in the desert WORK ??

Maybe I can turn OTTCT into a mobile summertime pizza oven ?

OTTCT, Howdy;

They work very well
Sent to you from the Hatch area of N.M. where there is a 10 acre
field of Solar collectors that each measure about 20' X 40' and are computer
driven to have a maximum exposure. They don't have anything behind them
like the roof of you CT so the breezes help them keep their cool.
Our daily temps. have been at or near triple digits since the end of May.

This guy splains it all. His summary: "If it seems too good to be true, it's too good to be true".

Hope this clears it up a bit.
