I know I'm repetitive, but I want to also comment for the algorithm. I'm so glad I stumbled upon your channel. Anybody that will stumble upon it is very lucky. Thank you.

There are plenty of van channels with sweeping views, drone shots and slo-mo footage of running dogs. There is no other channel like yours. Thank you.

You should be so proud of yourself. This video is comprehensive, well-thought out, and expertly delivered. I learned a lot. Thank you.

I'm glad I found your youtube channel. Thank you for your informative, chit-chat-free, organized, and helpful videos. Keep up the good work!

Best van build channel bar none.

In the days of most people just stealing from each other, it's refreshing to find someone who's still giving away such a plethora of knowledge. I'm truly thankful. May your material reach a larger audience, and your revenues be worth doing these excellent videos! 🙏

Hey Dude, I really like the way you present information. You have a charming, easy going and comprehensive delivery. I also admire how much research you do and how in depth you give your information is such a clear manner. Rock on and thank you for making this content!

Moser, your channel is gonna kill it! Extremely well done and comprehensive videos. Watch that Will Prowse video where he talks about his affiliates programs, channel, and books revenue. Your potential is huge.. Also, set up a Patreon and that Amazon click through kickback thing. And where the heck is your website..?

Outstanding review. Thank you!

loved watching these videos

Well done and well thought out. Always a thumbs up video 👍

The video that I've been waiting for and didn't know it! Thank you. Very informative.

Another great video. These are all great.

Another outstanding video, thanks Sam.

Thank you. This is an awesome video. Very informative. I appreciate the time you took to make and share this video.

GREAT VID. Thank you for takin the time to make this

Love your videos! Best van build videos on the web!

extraordinary review, be blessed man

Excellent comparison

This is great! To the point and informative. Thanks for the upload!

Thank you again Moser for a well produced video - so informative! I appreciate the information delivered clearly and straight to the point.

I’ve watched around 5 videos from your channel, you produce amazing content! Thabk you!

Nice presentation. Your videos get right to the point and cover what is needed. Subscribed!

Amazing playlist, keep it up!

Moser, you have made an outstanding series of videos. Well done! I will subscribe. Keep up the good work!

These videos are extremely informative and helpful! Thank you so so much for making these, Sam! You’re truly making my journey to van life possible.

I had not thought of Thinsulate or wool! Thanks!

This is by far the best van insulation video comparison I have seen. Thank you for all of the information!

Many thanks for such a well presented, informative, helpful upload

Very clear thorough review... great job young man goodjob. Thankyou

The BEST insulation comparison video. Helped me to choose the right material! Thank you!

Moser, another good one buddy! keep it up!

I just started my van conversion here in Brazil and your videos are at the same time informative and inspiring. Thank you so much Moser!

What a wealth of information! I was pretty lost before watching this video. I think I have a handle of things now. Thank you so much for doing all this research and then sharing your findings!

Thank you so much for the details and covering all aspects from price to R value to health..... Helped me to choose the one suit me the most.

So impressed with the time you take to analyze all the planning process and costs of the build out. You are the first KZfaqr I support through PayPal (and I watch the ads all the way to the end to help you keep making videos.). Keep the videos coming! Thanks.

Nice job!

All of these are excellent. There aren't a lot of really comprehensive resources for nitty gritty stuff like this. Keep up the good work.

Awesome video man! thanks!

This is easily the best video on insulation for vans (and maybe about insulation in general!).

Great information. This was just what I needed. I love all your videos. You should start a roving van buildout business. Where you travel around and help people with their builds all over the country. I'm in Texas.😎

I can't believe that you are covering heat transfer. Good on you. I appreciate your delivery. Thorough and organized.

This is so helpful thank you!

Very helpful. Thanks!

Great video! Thx!

Very informative! Thank you!

you just confirm why I'm using wool . great content

thank you well done Happy Trails

One additional consideration regarding spray foam - be aware that many/most body shops will refuse to work on any area that has spray foam behind/near it.

Great info, thank you!

Great video man. You have a great grasp of a very complicated topic for such a young man. Thanks. How about a vid on van layout?

Very clear and well presented. A couple of points that made me ask wth? VOC's from fibreglas? I imagine this is referring to building a fibreglas shell with epoxy and the VOC's that result during curing. All loose insulation and some rigid foam (open cell like polystyrene) will allow moisture to pass thru to the cold metal surface and produce condensation. You need a vapor barrier with acoustic sealant at edges and seams to prevent moisture buildup and loss of insulation value and worse mold or rot. Finally, some rigid foam has a shiny polymer on one side. The air gap must be on the shiny side and that must be facing the heat source that you want to reflect. So if you want to retain heat in cold weather you want the shiny side inward with the air gap on the inside of the reflective material. This setup will not reflect heat away from the vehicle in the summer. To reject heat you would need the air gap between the sheet metal and the reflective material and then the insulation inside that. Heat transfer is very complex and you did a great job with a lot of information.

Havelock for my build. You just finalized that decision. Cheers from Canader eh!

thank you

Thank you!

I'm going with natural wool insulation in my future van build

gotta say Moser, Veerry infomative!

Thank you for another great video! I did not know that polyiso loses R-value in the cold. I am liking wool for my next build. I heard hemp is gaining popularity but haven't researched it. I am unsure on spray foam having heard batt insulation like wool and Thinsulate manage moisture better. Anyway, video is much appreciated.

Great video - very informative. I've seen some folks advocating covering all exposed interior metal surfaces with neoprene to combat condensation. Any thoughts on that? Seems like that might be better at absorbing moisture than combatting it.

VERY good video, thanks for taking the educational classroom approach. I don’t need to know what’s going on in your personal life when I am researching insulation. I am just starting to build my 2nd van, and this subject has gotten more brain processing time that most other up-fitting issues. I am beginning to believe most of us are killing a fly with a sledgehammer. Let’s face the fact that you are working inside a tin can. The structure of this tin can includes many, many hollow spaces that are difficult, or impossible to insulate effectively. You can fight this battle with 3 weapons; insulation materials, good heaters and good ventilation. The heaters and the ventilation are easier ways to effect the entire living area of your van/RV. Insulation is much more difficult to do this with. Steel is a great conductor and every surface that touches it moves heat into or out of you van. Forget a radiant barrier, you will have near zero effect on the comfort inside your van for your effort. If you insist on the comforts of a stick build home, stay home. If you want to live in a van in the outdoors, get a good heater, and season appropriate clothing!

reminds me of report presentation in college

the complexity in just insulating that the weird geometry of vans entail, i'm begining to the even more that the way to go is a box that you build out, and then attach onto a cutaway cargo van. Then maybe cut out a hole so that you can walk directly into the driver's seat. And also add some aerodynamic plastic fenders so that the oncoming air goes around the van more smoothly instead of a flat face of the box.

I'm insulating my van now. Your video was EXCELLENT. Thank you. I'm wanting to use spray foam in parts of my van I can't reach with the rigid stuff. Would spray foam make my van rust? Hope you can reply.

Very clear and informative presentation. But I thought you would cover vapour barriers?

Im trying to figure out what insulation would be best for irish weather (winter) loads of different info but this is helping break it dowm. Still cant decide tho 😅

Hey Sam, what kind of insulation did you use for those deep places near the wheel wells of your Transit van? I have a Transit van but am camping at a campground on Mcchord AFB in the cold and I use an electric heater to keep warm but condensation is building up real bad on the wheel wells and in those deep cut outs. Thanks! Happy Holidays 🎄.

Hey Moser Thanks for bringing us these gifts of information I am truuuly grateful I'd even like to donate any platform for that ?

Hi Moser! Im thinking about insulating my van with 20mm Kaiflex but I'm not sure if I'd need an aluminium layer too... what do you think about it? do you think Kaiflex (or Armaflex) is a good choice? Congrats again for your work and channel and thank you. Greetings from Spain!

For non-Americans: this video describes R-values in [ft²·°F·h/BTU]. Most other countries will use an R-value that's also known as the Rd-value, which is specified in [m²⋅K/W]. It is a factor 5.678 lower than the American R-value. Hope this helps, it took me a while before I figured out why the values in this video were so high xD

What about Hemp? Thanks for a fantastic video

Great video as always Sam. Do you have amazon affiliate links? i didnt see any on your site id like to support the channel

What if you used the highest R value per thickness material, and then coated it in some sort of sealer prevent moisture from degrading the material as well as to trap the harmful particles and fumes from getting into the air? And if the sealer is a thermal bridge, just wrap the sealed rigid foam board with wool to mitigate some of the thermal bridging, effectively turning a parallel thermal circuit back into a series one.

It sounds like your favorite choice is wool. Is that what you would build with now?

Thanks so much for this! How thick of natural wool insulation would you recommend for a Van prepping for a Michigan winter?

Nixt.

How would you ventilate insulation? By having some space between the insulation and the wall siding?

Thank you, Sam! I was hoping for some information regarding fire retardation.

One upconversion company's experience on KZfaq said they have tried different types and methods of spray foam with panel warpage from the exothermic hardening process of the foam. It would be interesting to hear if DIYers have had the same experience?

If I may add: spray foam will fill drain holes, so they won't be able to do the job they were intended for.

The best way..to insulate a van..is to pray it snows a foot…lol ..Eskimo talk 😉

for a radiant barrier, doesn't the air gap have to be on the outside (aka the radiation source), rather than on any one side?

I'd be really interested to have the fire risk/retardant values in these also! Is thinsulate more fire retardant than wool? That would be the only thing making thinsulate the better option

I’d like to know about vapor barriers. Will a vapor barrier keep moisture out of insulation? What options are there for vapor barrier material? Is a vapor barrier compromised when screwed through to attach a plywood wall for example? I just watched another van insulation video, where foam board was used on the floor and ceiling and then mineral wool in the walls and crevices. The argument was made that the vapor barrier was critical to seal the insulation in so that moisture from within the van could not reach the insulation. So reflectix was used as a vapor barrier material and was completely taped in place with aluminum tape. Then plywood walls were attached to that.

How do you fix Thinsulate to the walls and ceiling of the van? If you do it with glue is there a good glue that doesn’t have off gassing problems? Are there other clever ways of fixing it to the wall? Also if the insulation isn’t covered with wall paneling of some kind will it’s insulation properties suffer much?

What are VOCs? "Volatile organic compounds (VOCs) are organic compounds that easily become vapors or gases. Many VOCs are hazardous air pollutants." (I had to look it up. 😃)

ps: I was a bit confused when you mentioned at the end the sound-deadning isolation without mentioning more Don't you use Thinsulate for that ? Thanks !

Algorythm come on!!!!

How is cork more sustainable?, they are already using rubber corks for wine because of the cork shortage.

Weight is important for my planning. Kg per m3 would be nice. Cheers.

The simple answer is : insulating a van is expensive if done correctly. Most people use cheaper products to cut the cost. Use what the companies who make camper vans use and do it once.

What about Hemp? I think you'll be pleasantly surprised.

What about HEMP?

After 4 years, covid and camperization business growth... is there some improvement? Some new material? After all your experience, what could be the best combination between cost/insulation and health care of the insulation materials? Thanks

Rock Wool is not safer than Fiberglass. Just an FYI.

What about Armaflex?b

Recycling plastic is best by far

Insulation is just one of several layers to use in Automotive applications. You can use any type you like. You apply it wrong. You're wasting your money and time... And yes I tried most of them. Only one way works to stop heat\cold transferring to the inside\outside of the Vehicle. So if you want true four season insulation properties. Learn how to use and install the stuff...

Great video. Just can't get use to understand R value, instead of U value (which is regardless of thickness of material). R value is a misleading&confusing American term. Anyway I'll check your other videos, it should be informative.

People die in fires..more from the smoke..then the flame…cork is known as the smokiest ….you don’t want that ..in your ‘house’…building science 101
