We talked to some farmers in Ireland and other parts of Europe and was surprised to hear that a lot of their sheep's wool is actually discarded! It appears that the cost of shearing and selling just isn't worth what they can get for them. I think more people should use sheep's wool. Great video!

[@dogcatmanvan]

That's really interesting. I would've assumed that it was largely recycled and sold in some way.

[@murphyandmurphybrand]

good job... very good video.. how many boxes you use for that van..? thank you for shearing .

[@dogcatmanvan]

Hey there! For our size van we ended up using 5 boxes, each 100sqft. We originally only ordered 400sqft but we laid it on pretty thick and ended up ordering an extra box towards the end. I think it depends on just how insulated you really want your van to be.

[@Eugen-2u]

good job guys. I see at the end you have a lot of that square aluminum structure installed already . got my hands on some office panels and I have to strip the profile off and planning to use it as well in my interior structure. do you have a video on that too? thanks keep up the good work and keep the fun with it too.😀

[@dogcatmanvan]

We used aluminum extrusion for our framing which I'm guessing is what you're referring too? We made a video on it here. kzbin.info/www/bejne/nnmpaKlvl5x7oKc

[@joerad4722]

Came here looking for info and this was a fun watch -- sub'd! What about the front doors? Did you do the front doors? Also, if you're looking to dampen road noise I would add do a noise treatment in the front cab that is easy to do. It's 3 parts -- CLD tiles to eliminate the pinging noise, then a Mass Loaded Vinyl sheet with Close Cell Foam -- that will kill road noise big time in the CAB part at least

[@dogcatmanvan]

We didn't insulate the front doors. Have you seen people do that?

[@joerad4722]

@@dogcatmanvan I think of it in terms of a house, you wouldn't skip insulating a wall in a house right? You want an fully enclosed and insulated space as much as possible (The firewall and windows are not directly doable). Plus, if you do the doors it will give you a chance to help with reducing road noise. I am not sure how complicated those doors would be, but I've done treatments in the past to car doors before for car audio purposes and it's always worth it just for the road noise alone.

[@geekazoid]

we used shredded wool which you blow in behind a vapor retardant. wayyy more serviceable for walls

[@Give-it-to-God]

Holy smokes that's a FULL BLOWN AWESOME insulate! Question: if I won't be living in it or even camping much, can I get away with just doing the walls and floor and leaving the headliner intact the way it is?? (Conversion van) I'm doing a semi van build.... meaning I'm semi lazy😊 ALSO....if the wool sags, that means we have to replace at some point??🤔 Should I find your other video about wall/floor insulation??😜

[@dogcatmanvan]

It's completely up to you whether you insulate the headliner or not. It helps with noise reduction in the cab, but you can always add a divider so you can section off that front area. You loose a lot of the hot/cold in your van from the cab through the windows and door seems regardless of insulating the headliner. The wool shouldn't sag if you have it held in place behind your walls properly.

[@Give-it-to-God]

@@dogcatmanvan notes taken and thanks!!!

[@ronethridge9875]

insulation pays for its self in the long run-saving to heat the van/your insulating your home on wheels/great job /now time for a cold one/thanks much

[@KB-mm2ti]

So how many sq ft of the havelock wool did you end up using for the walls, ceiling and doors?

[@corydwagner]

Are you going to install a vapor barrier, or does that mess with the whole absorbs/releases moisture thing?

[@dogcatmanvan]

No need for a vapor barrier with wool. It absorbs the moisture and then lets it evaporate.

[@katydidnt3906]

A cardinal rule in building is never double vapour barrier. Since the van shell is a vapour barrier, if you add wool followed by another vapour barrier, you have a double vapour barrier, and the moisture has nowhere to go. One side has to breathe.

[@brettbutler9730]

what are the strings for? u putting the stuff over them?

[@dogcatmanvan]

The strings were to hold the insulation in place.

[@ExploringJ]

My eyes as someone who has a background in construction watching this 😳😵

[@MaximC]

Wool is one of the best, if not the best option. But I wonder about sagging and about it touching the metal. Like let's take sagging - I think it definitely happens, with time, a lot of it sagging and just leaving a lot of wall basically without insulation (I think I saw some photos of that), and I'm not sure what would be the solution to that. Probably just periodically adding more wool? But that's assuming it won't start to get moldy... Vans are kind of terrible if one wants to use wool/organic materials, with all those cavities and it being all metal/worst thermal bridging. But these are the risks and disadvantages one should take in order to avoid using less sustainable materials/materials that emit VOCs.

[@JonesJr_art]

I brush as needed, it can be more than twice a day depending on what I've put in my face. 😂

[@bammargerat6561]

Can someone clarify what difference it makes to install electric wiring before insulating with wool?

[@dogcatmanvan]

I think it just comes down to where you plan on running your wires. If you think you're going to fish wiring through small cavities that will end up needing to be filled with insulation, it's a lot easier to fish those wires when the cavities are empty, ie non insulated, rather than having to fish the wires through the cavities already stuffed full of insulation. Does that make sense?

[@ScottSharpe2121]

2-4 times is fine. Usually twice, but I also only eat twice a day. Big question is do you brush right after you wake or after your first meal?

[@dogcatmanvan]

Ohh that's a good one. We both usually brush after we eat breakfast. Does that have a lot to do with things?

[@MissyPippyCrafts]

Brush before you eat or wait one hour after you eat.

[@Jayda08]

When you installed the permanent walls, the moisture gets locked in the wool and has no where to go. Good job! 🤣🤣 You have to vapor lock the walls and ceiling to avoid/prevent all moisture buildup.

[@donnacason1607]

What is the black/gray square that are already in the cavities? is that something you put in already?

[@dogcatmanvan]

Yeah we used Noico sound deadening. We have a video on that as well if youre interested

[@277kne]

Will moisture get into the wool insulation when the walls are covered? Is the Havloc wool critter and insect repellent? Maybe you will get a hygrometer and a dehumidifier.

[@MaximC]

I wonder about that too. Although even if it wasn't covered, it would be the same question I think, the condensation will happen on the metallic walls in any case. From what I understand, anyway.

[@dogcatmanvan]

It will, but the wool should absorb the moisture and then allow it to evaporate without it loosing it's insulative quality. It's also treated to be insect repellent.

[@katydidnt3906]

After over 2 years in my van, in Canada, I can say that moisture most definitely DOES accumulate between the wool and the van shell. Often a lot. I also had to replace the rear tail light assembly in my Promaster because moisture shorted it. There was Havelock wool in that cavity. I'm not convinced of the moisture management claims, but have no scientific proof without tearing my van apart to assess for rust.

[@MaximC]

@@katydidnt3906 Yeah, it's a tricky thing with vans. The problem with vans is that one doesn't have flat walls (like one has in a tiny house on wheels, for example). Because if one had flat walls, one could just apply a layer of insulation that would create an air gap between the metallic walls and the wool, and the condensation wouldn't be a problem. Or if vans were slightly wider, one could have just not bother with the cavities and apply that layer of insulation (that creates the air gap) and the wool right on top of the walls. That would've been perfect. I think they can make wider vans, I mean according what's allowed legally on the roads. I wonder if manufacturers will eventually have wider versions, for those who want to do a van conversion.

[@MaximC]

If only vans were slightly wider. We could apply the insulation right on top without bothering with the cavities, have straight layers of insulation, an air gap layer first and then the wool, and have no issues with condensation or mold. Like we do in tiny houses on wheels. But with the current dimensions, if we were to do that, it probably would mean sacrifice too much space inside the van.

[@fredsmith2299]

NRC gives a good clue to good insulation ... I once rented a place where I could literally hear people talking outside ... there was no insulation ...

[@dogcatmanvan]

A lot of apartments are like that. It's like they have paper thin walls!

[@gigglinggypsy4636]

How tight did you stuff it? The air space inside the wool is part of the insulation value. Looks like your project took 3 times the amount of wool recommended. Curious to know how well the insulation works when packed this tight .. (I'm a veteran wool spinner and knitter, so have been working with wool for many many years). Have you found that packing it tighter is more efficient??

[@dogcatmanvan]

It wasn't packed that tight especially after placing our 1/2 and 3/4 furring strips and walls on top. We definitely put too much on the ceiling though. We could've done half as much up there. Overall it's been working great so far.

[@funzeevanzee]

Great video. Technically, you should brush and floss morning and after every meal...

[@thebenson1983]

great Video as always. I have used a havelock wool is ok product. BUT it's too expensive and a pain in the ass to work with. All my vans I build I use micro cell foam and layer 3m insulation in them. This process isn't cheap but its not back ordered and you get twice the R value then Havelock wool and Super easy to work with. PS you use way too much insulation those walls need to breathe.. One more question how long did it take you to insulate the van? I just insulated a 170 extended sprinter yesterday and it took one day. you spend over $1000 to insulate that van and labor . I' would be out of van business using that product.

[@dogcatmanvan]

If we were able to put a full days worth of work into it, it probably would've been a day and a half or 2 days working 8hr/day. The total cost of our insulation was $750 which is pretty cheap not including our labor. I think it just boils down to the type of product you want to support. I know that's not always feasible from a business stand point.

[@phennexion]

Do you guys plan on using Reflectix on the inside after the wool? I hear mixed opinions about that.. like it's almost useless as a reflector of radiant heat once it passes the steel exterior of the van, and it's expensive... I was just thinking of using standard vapor barrier instead.

[@MaximC]

From what I understood, unless you leave/make some space between reflectix and the van walls - it's useless to apply reflectix. And regarding vapor barrier - one should not use it (the walls should be able to "breathe") or one should use a kind of vapor barrier that can become permeable (like Intello I believe). Also I've heard from someone that they didn't use vapor barrier in the floor, because he saw that it created mold inside the floor. One should really understand a bit the technology of insulation first, because some ideas like using vapor barrier and such may seem clever when in actuality they aren't. P.S. Also you might want to check out Moser Makes' videos, he made some good ones too.

[@phennexion]

@@MaximC In almost every van build you see people put TONS of reflectix on everywhere... and I'm just like, why? lol and they say for vapor barrier, sooo... i understand not wanting your moist air from the van condensing say.. on your metal floor of your van - but it's gotta go somewhere. So by covering everything in their reflectix vapor barrier are they basically creating a bubble where the moist air most likely escaped via the fan at the top?

[@dogcatmanvan]

We won't be using reflectix

You don't want wool in your walls if you live in a humid environment, air circulation is poor inside a wall. Wool can absorb up to 30% of its weight in water and it needs air movement around it to allow any moisture to evaporate.
