What I feel should've been talked about is the condensation on metal when the temperatures inside and outside are different. For that reason stuff like Armaflex is great. I personally don't understand why you'd like to put wires under the insulation though. Just more convenient to put them on top where they are more reachable when you want to modify/add/delete parts of the electricals.

wire routing takes up a surprising amount of space in such a small area, especially if you want it all to still be accessible. Chances are you will have built significant internals on top of the routing and will be loath to change it anyway as you will rip out lots of stuff. And with careful planning you are unlikely to actually change the wiring arrangement. It's actually less planning than you would put in to try to make the surface wiring still accessible but still discreet.

i have also used armaflex on parts of the van (internal side of interior ply panels on rear and side door, where rigid board is difficult to fit and spray foam will interfere with door mechanisms. it works very well, however, where there is a large temp gradient (~40C in alpine winter as insulation for the Maxxfan port) i find that it degasses a bit and shrinks by about 3% (1cm across a 35cm width). not sure whats happened in the door panels

I love these kinds of videos!! I am doing a vanbuild right now and I have a building science university degree. I want to add onto the vapour barrier debate. First of all, I get why you would want to add a vapour barrier, I know the importance of it in a house. However, there are a few fundamental differences between a house and a van: metal exterior and diy building. For a vapour barrier to work, every puncture of the barrier needs to be sealed again. If done perfectly the vapour barrier adds to the build big time, but if done imperfectly, it has the opposite affect. Where the screws go through (metal and therefore can get quite cold in some situations) condensation can happen, which due to the barrier cant escape. Mold will form around the screws there. Also how sure are you that the outside of the van is air tight (for years and years)? After buying an old van I am not too sure that this is the case for our van (even after doing so much work on it to try). If it is not air/water tight in a tiny spot, condensation will happen that has no way to quickly dry out and therefore mold will form. I know that this is a fairly new discussion for van life, but RVs are around for longer and they are made with vapour barriers. Older Rvs are now full of mold, that is why they always have a very distinctive smell. I decided on getting an water absorbing insulation that is good against mold (sheeps wool) and a construction without vapour barrier that has a lot of breathability (insulation, air gap, cladding which is what they would do in a house). Mold in a small tiny house is very unhealthy and toxic, I would not risk it!! Also: consider what kind of particles insulation is emitting. Usually, normal house insulation is not fitted for tiny homes because it is harder to create the passive ventilation (in housing MANDATORY, when using non natural insulation and building materials) that keeps the air clean enough to breath safely. Thats why tiny houses are often insulated with wool as well!

Hi Marit, I'm an architect, who has some experience in detailing building envelopes. At least in Australia (I can't speak on other places) there is a strong move to using vapour PERMEABLE membranes, such as CSR Enviroseal Proctorwrap. The difference between this and traditional vapour barriers is that the permeable ones are designed to allow water vapour to transfer without air (and hence your thermal air barrier). This is important in preventing moisture trapping in the insulation zone and causing mould, but that moisture will transfer into the van. However, if there is an air gap and a vapour barrier, vapour will collect, and run down to the bottom, which is where Margaret rightly said to keep the channels with drip holes free. As for breathing /cooking /other things ;) you need to open the roof vents /windows and allow some air to come in and out.

As a certified home inspector and sub contractor that has built, remodeled, and repaired moisture damage on many homes, I can assure you that you SHOULD NOT USE A VAPER BARRIER! Also, only use breathable insulation! The sheet metal on the van is a vapor barrier. If you put one vapor barrier on top of another, then you are creating a place for moisture to be trapped and start molding/rotting materials. Only one side of an envelope should have a vapor barrier and that depends on the climate. Basically, you want the vapor barrier on the HEATED side of the envelope. So in Florida, you put the barrier on the outer sheathing. In Maine, you put it on the inside. Unfortunately with vans, we're stuck with it being on the outside. So when you run heat on the inside during winter, it's best practice to just make sure that your insulation can BREATHE and dry out. This mean, no extra vapor barrier, and no closed cell insulation! Closed cell still allows moisture over time, and I've seen and repaired a lot of rotted sheathing where closed cell spray foam was installed.

I only always hear insulation in the context of being warm, but insulation works two ways. A well insulated house or vehicle can also be a lot cooler. Given that you also do the same as in the winter, keeping all the doors and windows closed when it's outside warmer then inside (ideally also darken windows). When an AC is being used, this also means that the AC will work a lot more efficient. In general rockwool is always a very decent go-to, not as good as foam boards but cheaper. Just not really nice to work with (nasty, but NOT lethal) , not as bad as glass wool. The more organic kinds are really nice on paper, on practice their R-values are kind of sad unfortunately (as much as I REALLY wish that wasn't the case) Personally I always just go for hybrid approaches. There is no reason to go only for one type of material only.

Rockwool is actually pretty safe. Just wear a dust mask and you're good to go. My plan for my insulation (I'm very close to that phase in my build) is a combination of as much as I can install foam panels with some sprayed foam to seal, rockwool in the wall conducts and other tight spots or... near door mechanism. And a layer of reflectix covered air bubble plastic wrap. Should be good enough... The bottoms of the walls bothers me to be honest. I really don't want moisture accumulation there, but I don't want cold coming from there either... Maybe the bubble wrap reflectix will be enough there 🤔😅

Well, it's not a matter of agree/disagree but I used 1/2 polyiso board (that hard stuff) and it will bend and slightly fracture to accommodate a curve, primarily the roof. What I did first was EZ-Cool (reflectics-like) everywhere first that could apply a sheet to via 3M-90 as I did not want the bare metal exposed to the climate inside and potential gathering of moisture and subsequent rust, mold, smell. 3 years no problem. Used R-13 in areas could not do this routine but EZ over these areas too as a vapor barrier. In a small 130wb MR Transit so at 5'11" you use the 6' clearance up easy. 1/2" poly on floor with a 1/4" wood sheeting and indoor/outdoor carpet glued on. Yes, it gets cold IF you let the cab area cold air in so a floor to ceiling curtain a must. And yes, gotta do both the rear doors (but have a 1" wall in-between me and it) and the slider lower portion. Gotta say though, the EZ directly on the metal must have some benefit as it is not cold to the touch as bare metal is so transfer of cold must be being reduced to some benefit; these were areas I could not access for insulation (B pillar, C pillar) when I was doing the job. 18 out last night and low of 63 inside with my heater on low/ 9000 btu (Dickinson P-9000) fan on high. High fan would yield 70 no doubt but very comfy overall.

I'm an architect. Here are some tips for insulating. When we insulate buildings, it's based on the climate zone. Obviously, van life is mobile, so that's a big challenge. I would use a middle ground climate zone for basis of design. Climate zone 5. In climate zone 5, walls would need an r-7.5 (coninuous), roof r-25, floor r-10. 1"of polyisocyanurate has an r value of 5. Thus, walls would get 1.5", roof would get 5", floor would get 2". This thermal envelope would give you the most optimum performance. Having said that, 5" at the roof may be unachievable due to the height restrictions in the van. I would at least do 2". Another thing that may help is installing a fluid weather barrier on the insulation boards between the boards and the interior face of the metal. When you insulate a van, you will create a dew point in this area. Water will condense there. This weather barrier will give the water a drainage plane to the vans weep system. This video does mention the drainage cavities. The weather barrier is different than a vapor barrier. I would not install a vapor barrier on the interior of the van. It will block natural permiation that is needed for the space to breathe.

Thermal barriers are tied up with dew point and interstitial condensation. Warm air will hold a percentage of water, cold air holds less. As the warm air cools there is a point where it has to give up the trapped water. Hence where water filled warm air comes in contact with cold glass, or metal, condensation forms as the air cools. This caused a big issue when people filled their house cavities with insulation as, where previously, the point of condensation was within the cavity, the moisture would drain away, insulating could mean the moisture would form within the insulation soaking it and reducing the level of insulation rather than increasing it. Your point in maintaining clear bottom cavities is well made as the outer skin of the vehicle is likely to get wet on the inside and that water has to go somewhere. Vapour barrier - you don't really want your water filled hot air to escape to somewhere it can cool and condense. If it can escape and come in contact with cold metal it will make the surface of that metal wet. If you trap that water filled warm air this is good, assuming it doesn't cool because then it still has to give up that water. In summary - it's complicated. You don't want air to cool behind or within something that can absorb moisture because it will become wet/damp. Your point that clothes in cupboards are insulation is reasonable except, if the inside face of your sweater is 20ºC, and the outside face is 0ºC, any moisture in the air will be given up between those two points ie, in the middle of your sweater. This is interstitial condensation.

in our build, we used Rock Wool and stuffed it everywhere, literally if there was a gap, we put some in there. Not packed it in, just put it in. We took the door panels off stuffed in in there and between the cabin topper and the frame. Then we put a vapor barrier over the walls of reflectix and reflectix tape. then put up the furring strips that gave us a good inch between the reflectix and the wood walls. For the floor and ceiling we used insulated foam boards and reflectix tape. We have spent the night in 18 degree weather by turning the van's heat on for about 10 minutes, and it kept the van warm all night. And yeah, it took us A LONG time to get all that done too.

The insulation debate online is surprisingly full on! After long deliberation we went with 100 percent sheep wool insulation, including floor, ceiling, doors and barrier to the cab, for good R-value, moisture control and environmental friendliness. We decided not to install a vaper barrier due to the theoretical worries moisture can get trapped behind it if there is a hole anywhere. So far it has been holding up well, we don't have a proper heater (but do have some radiant floor heating) and we are reasonably comfortable until about -1 celcius. One tip for anyone: we love love love our 100% cork floor (wisecork), as it stops the floor from feeling cold, another great insulation addition.

I agree 100% with everything you said (use of reflectix as "insulation" and insulating below the floor level and blocking the drains being the ones I see more often) but I disagree with one thing you already did on your van (not sure if the shots were from your previous van or this one). You saw how strong Kingspan is, you said it yourself. So why use battens on the floor then? You can lay the plywood directly over the Kingspan sheets and it will be perfectly fine. That way you will also minimize thermal brakes (even if it's just the floor, which is not really that important unless of course, you do heated floors). If you really need the battens to bolt your furniture on (not really necessary) then just put battens where your furniture will go.

Along with foam board, we used mineral (rock) wool, which I don’t think you mentioned. It doesn’t absorb moisture, is less expensive, and is easily available at Home Depot or Lowes. Followed by a vapor barrier of reflectix. Sheep wool must be purchased online and it’s difficult to know exactly how much to order. It was nice to be able to just go buy more mineral wool when we needed it. Plus when we were building, Havlock wool (sheep) was on back order. (We chose our materials because of the Greg Virgo videos.). Anyway, our van stays comfortably warm now. We did leave an edge of exposed metal around our windows so to be able to attach the window covers with magnets. I used reflectix in the window covers, with batting, covered with ripstop. They work very well. And because we insulated the cab, we haven’t needed a curtain which is nice because we use our swivel seats. Sorry this is a long comment. I enjoy your videos.

Rockwool's technical paper clearly states that it's not to be used in high humidity environments. You can't compare a house with several cubic meters of displacement with a tiny van that gets huge amounts of condensation every day when people live in it. Hydrophobic doesn't mean waterproof. It will withstand the moisture levels of a typical house and that's about it. As for the fire resistance properties, with all the other flamable materials inside a van, if your van catches fire, insulation fire properties will be your last concern.

Specifically for windows you can use a product like 3M crystalline to reduce the heat intake of your windows. That’s the only product I have experience with, I’m sure there are other products. First in a friends and my classic cars. I use 80% and because it’s pretty much clear I can also use it on the windshield. I cannot feel any heat transfer when in direct sunlight on my windows now. It makes a big difference. One of my best friends family used it to do their over 100 year old house with single pane windows. It halved their AC bill and changed how the house feels. I texted him to see if it made any difference in the winter with cold and have yet to get back an answer. One of the problems we have with classic cars is rust when the drain holes get blocked. It might be a good idea to make sure all the drain holes are clear. In cooking I found that propane contains a lot of moisture. I would think avoiding propane for products that use a dry heat would help reduce moisture in the van. What are your thoughts about using a humidifier in the van to reduce moisture?

To further clarify this: yes, heat can travel in all directions but only through the mechanisms of convection, conduction and radiation. Convection is (in a van) hot air rising, as described which is largely what the ceiling insulation tries to prevent going any further. Conduction occurs when things touch each other and the heat transfers from the hotter to the colder (eg hence the thermal bridge of the metal described in the video, with heat from inside the van transferring to outside via any exposed metal). That leaves radiation (light; ultra violet through to infra red) which is what Reflectix tries to “bounce back”. You need an air gap on the reflective side because without one, heat would simply conduct between the touching materials into the Reflectix material itself and then into the side of the van.

Regarding installing foam board on a curved wall, a truck is that you can measure the shape of the wall with a contour tool (sections of straight edges held together by hinges) and score the backside of the piece you intend to install at the same locations as the hinges on the contour tool. The foam board will then fit curved walls very well

I really don't see spray foam as that much of a risk at all. I had a guy who regularly spays the inside of shipping containers and canal boats do mine. It was relatively inexpensive, quick, clean and fantastically effective. If I was doing it again I'd elaborately mask the side and rear doors so he could do those in their entirety. Spraying interior grade, closed cell foam ticks a lot of boxes in one operation: sound and thermal insulation, vapour barrier and it makes the panels really rigid. So much so that I did not bother to batten my van out (apart from on the floor) before having it sprayed. I got mine done before I cut the windows and sky light out so I have nice window shaped insulated panels that I can put back in against the glass for great window insulation. There's no downside that I can see.

First....Happy New Year! Second....I found this video and info VERY helpful. I'll be starting my (short) bus conversion in the spring and am gathering as much info and advice as I can.....and one important focus is insulation (which I haven't actually seen featured as a main topic on bus/skoolie/ambo tours). I currently live in Ontario, Canada, and once my conversion is completed I'll be "chasing 70" as they say, so I'm not concerned about freezing cold or boiling hot temps, but I will have pets in my tiny-home-on-wheels (I have one dog and one cat now but will be getting another---larger/for protection--dog once I'm on the road) so for them I want the rig to be at a consistent (or close to consistent temp). I also will be doing this conversion on a limited budget....so my question....do you think it's wise to do, the foam board in the floors and walls and then wool for the back door and ceiling? Also, I watched a great short bus tour last night and he made a great point.....many people block off the front of their van/bus/shuttle/ambulance from the "main house part" by putting that barrier BEHIND the driver's seat, but that's a bad idea when it comes to safety as you want to be able to access your driver's seat as quickly as possible in case of attempted-break-in or other danger near your rig....so he recommended (and he's lived on the road for many years) to put that barrier (black out curtain for instance) in FRONT of the driver's seat. So sorry for the long comment. P.S. I really miss the videos you used to make, where you talked about the good and not-so-good aspects of various vanbuilds :-)

Great talk on insulating properly. My one concern is the statement that having more insulation when you are in a hotter environment just traps the heat in. While true, it does not address how to keep cool in warmer environments without massive us of A/C. Clearly some insulation is vital or an A/C system could never keep up. I have yet to see anyone talk about venting a van later in the day when temps cool a bit to pull the heat out. The energy is trapped in the thermal mass of the interior, and I haven't seen a single design that has systems to deal with this. I saw Greg Virgoe's thumbs up, which is good to see. His talk is based in the science of construction and building envelops. Your solar panel lift is a fantastic design. I used similar lifts to open a "door" in the floor of my house to get to the basement. My first set of lifts lasted five years. Congrats on having the biggest power supply I've seen on any build of a class B. You guys win!

Love comprehensive videos like this! I heard someone say that water will always gather at the metal- it either gets past the vapor barrier or it comes in from the outside (through door handles or trim??) because vehicles simply are not entirely sealed, and that this can soak your insulation and lead to mold, etc. and thus you shouldn’t stuff those spaces with insulation but.. but then how to insulate?? Also, after years of wearing wool I became allergic so.. um.. careful.

Wool is a good insulation if it can breath, it absorbs moisture so it needs air movement to dry if it gets wet. If you want to learn best practices you can learn a lot from the professionals that specialize in construction and insulating metal sided buildings.

Margaret, THANK YOU for your thorough consideration of insulation. YES, important because it will determine, in large part, how comfortable you are in the van in the long run. However, when you mention sheep’s wool that has fiberglass woven into it (14:21), you say, “That’s (rats) not really a problem in a van.” While this may be true about the rats, having fiberglass near the living space and not having the fiberglass completely sealed off from the air we’ll breathe when we’re inside the van is UNSAFE. There is a reason that folks who work with fiberglass have to wear respirator masks. Protect your lungs from fiberglass particles AT ALL TIMES. Don’t use it in your van living space. Thank you. P.s: I LOVE YOUR CONTENT.

Can we talk vapor barriers for a moment? Vapor barriers can be great, but you shouldn't install a vapor barrier (on a van, or a house) without a clear understanding of what you're trying to accomplish. As Margaret says, living inside of a van will tend to raise the humidity of the interior air, and you almost always want to enable that moisture to dissipate to the lower humidity outside. You may also occasionally be somewhere where the outside humidity is very high, either persistently (i.e. high humidity summer locales) or temporarily (i.e. a rainy week). A common strategy to have a vapor impermeable envelope, which will prevent exterior high humidity from migrating inside, and use fans for when you want to vent humidity outside. As Margaret mentioned: there can be a lot of holes in a factory van, and so while sheet metal is vapor impermeable, you might want to add a vapor barrier to "cover" the vapor holes in the van. But if you're going to add an interior vapor barrier, be sure to not create a sandwich of two vapor barriers (the sheet metal and the installed barrier) with a gap between. This can easily result in compartments that don't readily shed humidity to either the exterior or the interior of the van. And what do you get with persistent high humidity in a closed compartment? Mold and other nasty things are a common outcome. Because of all that, I think there are two reasonable options with a van: 1) Don't add an extra vapor barrier. Rely on just the metal skin, and make sure that all the insulating material you install inside is vapor permeable. A well insulated van with vapor permeable insulation will only let moisture move slowly, so you won't rapidly get the outside humidity in the van, but it'll let all the nooks and crannies of the van dry out. 2) Install a vapor barrier as the very first thing you do, and adhere it with (ideally) no gap between the sheet metal shell of the van and the added barrier, so as to not have pockets that have barrier on both sides, and cannot dry to either the outside or inside of the van. Personally, I much prefer option #1. Note that installing two different vapor barriers is a classic mistake that people make building houses, and can have long term health consequences when mold grows in the walls. Note that it's very difficult to install a perfect vapor barrier. And even if it's perfect when you first put it in, you inevitably have penetrations later in the build, and wear and tear on the road, and it's unlikely to stay a perfect vapor barrier for very long. Edit/Update: I realized I didn't talk about one concern some people will be trying to address: condensation. If humid air hits the outer metal skin of the van on a cold day, the air will be cooled beneath the dew point, and condensation will form. If the layers of your van from the outside in are metal skin, insulation, and then vapor barrier, then in theory the vapor barrier keeps the interior humid air out of the insulation cavity. Even if the van is allowed to cool, the condensation will form on an interior surface that's more likely to dry quickly. But if tackling this design, it's a good idea to recognize that a perfect vapor barrier is hard to create and maintain as you're building out your van. It's very likely that high humidity air in the van will seep through flaws in the vapor barrier, into the insulated cavity, and then condense on the inside of the metal skin. Condensation sandwiched between two vapor barriers can take a really long time to dry out, and cause serious problems. So how to address this concern? One way to try and insure that the insulation is vapor permeable, and deliberately provide a route to the outside of the van, so that drying can occur. This takes very careful thought with a van build, since you have to insure that there's a vapor path past the sheet metal skin of the van. Typically this would have to be down through the undercarriage. A second approach is to install insulation that won't let humid air contact the metal skin, even if it leaks through the interior vapor barrier. This approach requires comprehensively attaching the insulation to the metal skin so that there are no air pockets, and using a closed cell insulation. With all the nooks and crannies in a van, in my opinion spray foam is the only viable solution for this approach.

What I‘ve learned is floor heating is important. You don’t want to stand at the cold floor. I‘ve only heating at the kitchen and in front of the bed. It make the life much easier when you have in the morning a warm floor. Also for the next van build I take a sandwich board for the floor. GFK foam GFK. Cut it like the original wooden floor and replace it. No small parts to worry. Very strong too. Insulation I have only 19mm Armaflex and nothing in the structure of the car. And it works fine up to -10 degrees celsius. Then my 2kw diesel heater is to weak for 23 degrees inside. All holes covered with Aluminum Tape. No vapor barrier. I learned from the caravan, Outside Aluminum, then Stryopor, and wood. You have the let air circulation in because the moisture can’t get out. One time at the day open all doors and let air for 5minutes in and never get a moisture problem.

There is one product I don't see used often in van builds, but has been gaining popularity in home construction. That is a spray cork application. The cork provides a thermal break on surfaces it's applied to. I think it might be an interesting method to look at perhaps in a future build. That's not to say it alone will be enough, but I think it might be a good product on the sheet metal first then Havelock or thinsulate etc on top.

Hi there, good vid, I have spent several winters in an uninsulated VW Cali and now have Ducato factory insulated camper. Not a huge difference in heating bills as small space. Of course as you know without ventilation you are just moving moisture around and it will inevitably form on windscreen or on cold bridges so most important thing is to avoid (almost impossible) trapped moisture and generally maintain an airflow via window, roof vents or whatever. Allow van to air regularly during day and check backs of cupboards for damp and dry where possible. We didn't find any big issues in the Cali as we popped roof as much as possible as well. In airtight and well insulated houses MVHR systems are installed but cost and space likely outweigh benefits in a van (you could design for a niche market? ;)

Van life is still a dream for me but it's a dream with structure. I was worried about the sheep and the and the fiber glass because people were worried about chemicals. But I think personally I would lean toward the fiberglass spray because I really want to be able to go everywhere and anywhere. I'm off the sheep now because I think it's a lot and it's just me.
