Truth. Aluminum causes moisture

[@cachecamper]

Correction - Aluminum is NOT a vapor barrier. See the correction video here - video - kzbin.info/www/bejne/maqXnnaegN6jjM0 I tried to rush that video and am new to video creation so I did not do a good job teaching. However, I believe I made a great video to respond to those who correctly schooled me. Lets make this channel a great place for folks to come for education and discussion. Happy to see your well structure comments! Thank you for watching.

Is it more like when you take a cold pop can out of the fridge. And it gets condensation. Warm inside your camper is your warm house. Outside in the cold is your fridge. Aluminum frame is the pop can halfway in halfway out of the fridge? And then the moisture collects on the dew point depending on temperature and humidity stuff. I'm not expert but trying to solve the mold problem.

[@cachecamper]

Yes, that's much the same. I'm making another video on this that explains better. The moisture is going to build up on the coldest material, which also happens to be the metal anywhere in the build.

[@TribalGlobe]

What a terrible explanation of physics. It's not because it's a vapour barrior, it's because of warm (moister laden) air contacting a cold surface condenses that water onto the cold surface.

[@cachecamper]

@TribalGlobe you are 100% right. I can make a correction video that better states that. I'm new to making videos and it's weired how once you're speaking on video your thoughts don't come together as good. I'll get better, but you are correct and that has been running through my mind on how I could have said that better.

[@TribalGlobe]

@@cachecamper Ok well I wish you good luck on your new video making journey!

[@cachecamper]

@@TribalGlobe I appreciate that very much.

Here is that correction video as promised. kzbin.info/www/bejne/maqXnnaegN6jjM0 I would love to hear your thoughts! Thank you for your critiques

[@CMCraftsman]

You need that pink foam on the outside of the metal. Especially if this is being used in a cold climate. The warm moisture laden air inside wants to move from warm to cold so every piece of aluminum is a thermal bridge aiding in its ability to do that. That means every piece of aluminum is a cold condensing surface. You need to keep the aluminum closer to the interior temperature than the outside in order for this to work.

[@EricMeatlikeaking]

Thanks for showing this stuff I was wondering how these things hold up. How do I find a camper that isn't going to have issues?

[@cachecamper]

You're welcome. Maybe I'll do a video on that eventually too. Every build method has its issues. I think that the totality of our channel is going to eventually answer that question. It's not a cut and dry answer. The answer for the type of good camper for you is going to be different for the guy standing next to you. I'll put up more and more videos that, hopefully, will better answer that question

[@ericmyers120]

Does coach campers have any interest in moving towards full composite panel construction?

[@cachecamper]

@ericmyers120 absolutely awesome question. I will be putting out a video on this. This question truly deserves a detailed answer. I'm a direct person and like to the point answers. But I do not have one for you on this. If you stay posted, I'll get a good and proper video put together for you on that.

[@ericmyers120]

That's awesome, looking forward to it. Also, I realized I typed coach instead of cache, sorry about that. Thank you.

[@cachecamper]

I slightly cover a little bit of my view on sips in this new video kzbin.info/www/bejne/maqXnnaegN6jjM0.

[@F550-OVERLANDER]

What if you welded the frame up then sprayed the entire frame with Lizard Skin's Ceramic Spray? This would seal the aluminum from thermal input. From there you could insulate the walls and skin them? Have you tried this on any similar spray on ceramic coating?

[@cachecamper]

We have never tried that. I'm not certain how that would turn out be honest with you. That is definitely something for testing.

[@functionalvanconversion4284]

Thanks for the information👍

[@svenjohnson2389]

Could you fill those tubes with an expanding foam product?

[@cachecamper]

You could for sure. But you do not want to speed up the process of rust, corrosion, and oxidization. A channel for moisture to run is a good thing. If you did a great job sealing every penetration, you could do that but you would want to drill your pressure relief holes so that you don't oval out the box tube.

[@Dingleberry1856]

Steel studs in builds are the same.

[@CMCraftsman]

That’s why we build out of wood.

[@americanfreedom1777]

Hmm, haaaa , you should hire an expert, you should use "offset structure framing" transfer for thermal block .

[@cachecamper]

@americanfreedom1777 That works well but is super expensive in application. That can most certainly be done in a custom situation, but budgets usually win. You price yourself out of the reasonable market and the benefit gained by the customer does not outweigh cost.

[@americanfreedom1777]

@@cachecamper hmm, using my method will save $ and eliminate the moisture accumulating inside the walls, or roof for that matter. :-)

[@cachecamper]

@@americanfreedom1777 I'm always open to learning. Would love to see what you're talking about.

Can you say misinformation? It’s obvious you know nothing about “physics” 🤣

[@cachecamper]

I made a correction video here. Thank you for calling me out. I rushed that video and did not do a great job. I'm new to making videos and I think I did a good job correcting and I would love to see your thoughts on this video kzbin.info/www/bejne/maqXnnaegN6jjM0.
