[@777rogerf]

@@wewerecamerashy5190 In my humble opinion, when you are not talking, no music would be better and, when not talking Traditional Japanese music would be sp appropriate and you should have access to recordings and advice in what genres would be effective and affordable, maybe free.

[@Anil18834]

What a wonderful struck of luck to have found a house from the 80s built in the traditional style. You own a jewel of a house and are preserving it beautifully while bringing it into the XXI century.

[@kennethbolton951]

One of the silver linings (excuse the pun) is that you will have a very complete record of everything you have done including materials used, difficulties and solutions. Invaluable for future projects, maintenance and repairs. For us it is invaluable as your mistakes don't become our mistakes. Thanks.

[@TokyoLlama]

No worries! That’s very true as I’ve referred back to my videos a few times to check to see how something was done when planning a new project.

[@OurHouseInJapan]

I'm about to start the insulation process on my 150 year old minka in Nagano. This past summer I re-insulated the kitchen using rock wool .... after removing a foot and a half of straw, dirt, and dust, which was i guess the insulation of the day. Great timing for this video! Cheers!

[@TokyoLlama]

Nice! What are you planning to do with your roof? I'm thinking rock wool or the Earth Wool, perhaps Neoma foam, keep changing my mind!

[@OurHouseInJapan]

@@TokyoLlama I'll do the inside cielings with rock wool and make that as tight as possible for now ( baby steps to retain heat). in time maybe put layer on layer. When it comes time to do the inside of the thatched roof, I really don't know. There is a nice part of the old house where I can reclaim a large room with exposed beams... the question is how many beams do I wish to expose vs. how insulated do I want to make it. A friend of mine did a similar reclamation and used beautiful pink fiberglass and finished with gypse. It seems to make sense for the uneven surface ... but seeing you work with the neoma foam looks so satisfying! I'm just getting started and loving it. I can't wait to hear about your windows, double pane glass sounds like a dream!

[@TokyoLlama]

@@OurHouseInJapan sounds great. Same here with the exposed beams but I’m going with beauty over practicality, so we’ll expose the all of the beams in the attic. In regards to the windows I found that the custom wooden windows are not much more expensive than custom sized hybrid ones. If off-the-shelf sized windows fit your openings that’s the cheapest way though.

[@sandracarli1110]

I live in Austria and Minka here is the name people give to a cow or cat. 😅

[@leelulady2010]

Looks great! My only concern is the pot lights. Here in the US you'd probably have a code requiring a cover (hat, if you will) to protect the insulation from directly touching it & causing a fire.

[@wfelixluck]

This was my immediate concern, as well.

[@davidscott3953]

Most likely LED lighting and thus not rally an issue. Old incandescent bulbs and or transformers got much hotter

[@spacemansabs]

he even shows on the fixture that it says not to cover it. And with google translate it seems to say do not cover with wood as there is a risk of fire. Not sure why he highlights this label if he goes on to cover the fixture anyway.

[@rsmith02]

Yes, I'd think you would just build a simple box over it so it's not in direct contact with insulation.

[@josephlai9759]

Thank you for sharing your project. You explained the original 'drafty' design of old Japanese houses very well and showed how you make sure that there are sufficient ventilation gaps between the newly installed insulation layer and the inner wooden wall to allow for air flow so as to avoid moisture retention and potential wood rot on the inside of the house. It also made me think about the different insulation wools you mentioned. I found there is a potential health hazard with glass wool if not handled properly. The comments contributed by your viewers were enlightening too, especially the electrical fixtures on your ceiling and the potential fire hazard with regards to contact with insulation material.

[@SeraphusInferis]

DUDE. Just shy of 500 bucks for proper insulation? That's a steal, mate. Really good work, by the way; I've insulated a couple attics, and you did that really well; a pro would probably charge well over a thousand (USD) for that job, and you nailed it for half to a quarter of the price! Keep it up!

[@deborahf3738]

You'll be a master carpenter by the time you finish the house. This is the neatest insulation job I have ever seen. Looks fantastic.

[@TokyoLlama]

Thank you!

[@Patraquashe]

The house really has come a long way since you started years back. Even as a viewer I feel a sense of pride in where it is at today. Great work!

[@TroelsDenLux]

Nice to get an update of the house! If you plan on using more of the blue foamboards in the future, maybe you should look into an electric hot knife or hot wire cutter. Looks like it was a struggle to cut through. Thats what we used to make architecture models with in university (don't know if it is common to use in building constructions). Anyway, just a tip:) and don't forget a respirator-mask or something. Those fumes are not pleasant!

[@TokyoLlama]

Thanks very much - yes, it was a bit of a struggle cutting through the foam, will check out the tools you mentioned!

[@heuhen]

@@TokyoLlama jigsaw is also a good contender to it. And something you can also use on many other projects.

[@heuhen]

@@TokyoLlama Take and check "bayonet saw" the question will be then, do you need it for just some insulation work.

[@5chevin5]

My house in Ibaraki was 8 years old when I bought it last year, a newish home by Japanese standards. Still cold in the winter and supposedly has more than average insulation, but under the house is very sparse. Once I heat it its fine, but those early mornings are chilly. We have double pane windows and the engawa heats up nicely on those bright winter days. It certainly is something to consider here in Japan when buying a home, but as with everything there are work arounds and solutions.

[@TokyoLlama]

I'll have to upgrade the underfloor insulation at some point unfortunately. Wish I knew more when the carpenters were working on the floor as I would have been more demanding, and saved a whole lot of work down the track.

[@markhenderson4435]

I look forward over time to the heating/cooling efficiency comparison that I just know you already have a plan to do in each season!!!!

[@TokyoLlama]

Yes, I put smart thermostats on the outside and inside of house last year, recording the temperatures so can do a comparison over time!

Thanks, appreciate the support!

[@janicebraden7961]

I’m enjoying the videos very much. When i lived in Japan in the 1980s it seemed such a shame so many beautiful places were being torn down so great to see its turning around. My question is why are you insulating both the ceiling of your boys room as well as the roof? when I renovate here in Canada, a knee wall area would be either/or. You want a continuous insulated envelope but in a cold place you don’t want to trap the air outside the sealed envelope (say in a knee wall area in a sloped roof) because you will get mold. Some heat will always escape from the boy’s ceiling into that space and it is moist.

[@Jesterttv]

Thanks very much for watching for so long!

[@heuhen]

I always love to watch other people renovating houses, since I have done that in Norway. And since I have done renovating house before, there is always times where I go: "oh, I wouldn't do that!" It is also very fun to watch how different people around the world do things. For example cables in the walls, In USA they just put normal cable inside with the isolation. While in Norway we put an vapor barrier between the isolation and the inner room, and build a little out for air flow and cable management, where we put cables inside flexible-pipes, to prevent fire/damage/electrocution/ and ease of maintenance (replacing cables). If it was in Norway, with our high difference between inside and outside temperature, we would for example on the ceiling put down a vapor barrier and then isolation (not those in bags).

[@TokyoLlama]

When the electrician came in to replace the lights I asked him about keeping the wires outside the insulation and he said it was okay, but it was something I wondered about. In terms of vapour barriers seems the Japanese generally feel the bags are sufficient!

[@Jordan-inJapan]

[@NAMI-xl5og]

With the added insulation, assuming you utilize a vapour barrier system, you will have changed the dynamics of the sit flow throughout your attic. One way to increase the flow of air at a small cost is to utilize “Roof Turbine Vents” which will pull a lot of air through your space, which will keep the areas moisture free. Just a though. Love your home and what you’ve accomplished. Excited for more content.

[@TokyoLlama]

Thanks, yes, I’m thinking of something like that, particularly once we insulate the roof.

Another great video Jaya. It is a balancing act in these old houses when it comes to insulation. The house needs to breathe and it is also needs to retain heat. There is no perfect solution it is what it is with these kominkas.

[@scotty6435]

Instead of just insulating, using some air gap sealing tape would be hugely effective. Any air gaps even in the ceiling will lead to a lot of heat loss that can't be mitigated with fibreglass insulation

I definitely feel your pain. My wife and I currently live in Kyoto prefecture and received a lot of snow this winter. Our house has a traditional house with no insulation or double glazed windows. The wind pours through and we cannot retain heat. My wife and I actually have chosen to move into my company provided apartment just to stay warm also, to save on the electric bill, which last month was more than I have ever spent in my life on electricity.

[@rsmith02]

Great, thanks for watching!

[@Wezqu]

Well the only thing I would have done there as extra would have build some walkways over the insulation. Its just if you ever need to go to the space with the insulation to do or check something. It makes so much easier to have at least a narrow walkway that you can use without worrying about the insulation itself or where you can step. Like if he ever needed to run some new wires or something for lamps and such would make that way easier.

[@rosiosilva1551]

[@erikpeterson778]

Is it wise to put insulation directly on the downlights? A short can cause a fire. I suppose they are LED so there is very little heat but I would still put a metal cup or something on top of the connections.

[@TokyoLlama]

These lights are rated for insulation to be placed directly over (probably should have showed it in more detail), whereas the old ones I replaced weren't.

[@nekkidnora]

I'm so used to seeing XPS board used as a crafting material for miniature landscape etc that I was genuinely startled to see it used for insulation, which made me laugh. I guess it shows what kind of stuff I watch/do on a regular basis.

I think it's a GREAT SPACE to have just for storage!!! BUT you would need to put down some plywood before storing anything of weight in there... - - The old style of houses NEVER CEASE TO AMAZE ME!!!!

[@davidbiddle3257]

Also, very smart to clean, first, before installation.

[@catinthehat906]

If you want to prevent convective looping and significantly increase the performance of that glass wool, a thin layer of foil wrap insulation rolled over the top is a very quick and easy job. It will also reflect heat in the summer and stop the room below getting too warm.

[@TokyoLlama]

Thanks for the tip! I’ll definitely do this on the second floor ceiling.

[@rsmith02]

​@@TokyoLlamaDon't add a radiant barrier. It traps moisture and will do nothing if installed on a floor as dust makes it non-reflective. It would have to be at the roof level with an air gap. You already have air leaks at the ceiling plane and need that air to be able to get out. If it were me I would have more carefully airsealed the floor and made boxes above the lights. Read GreenBuilding Advisor for more on radiant barriers and insulation.

[@TokyoLlama]

@@rsmith02 Yeah, I'm planning to put a radiant barrier below the roof with the air gap. I considered properly air sealing the first floor ceilings but didn't think it was feasible for the whole house and regardless, once the second floor is finished it won't matter so much.

[@coutopraze]

You're doing an excellent job! You'll end up with 200mm mineral wool laid over the ceilings wich is a huge improvement, check if you're happy with your heat losses after this. Here in the UK 270mm mineral wool is pretty standard to achieve the minimum U values required by building regs for new houses (0.16). It's quite a high standard to be fair but if you want to go above and beyond maybe in the future you can install a 3rd 100mm layer and bump it up to 300mm insulation! Best of luck, can't wait for the next video!

[@TokyoLlama]

Thanks, I'll see how it goes but hoping since it's going to be an internal ceiling space once the roof is done it will be sufficient.

[@rsmith02]

Rock wool is also good for sound deadening which is a bonus!

[@poelmeister]

Good jobu! :) The house wrap was a smart move. The key to insulating this place is to create a vapor barrier between the old wood/structure and your living spaces. Should you seal everything up, you would just create a new problem. This seems like a very smart insulation strategy.

[@rsmith02]

Not sure why you'd want a vapor barrier vs an air barrier. Keep the conditioned air in the conditioned space but let any errant moisture find its way out. Look up smart membranes, vapor permeable housewrap, etc.

Great! Another video from you is always welcome. I have to say, given the climate in Japan in summer, the traditional building system made a lot of sense. It really is easier to warm up than cool down, especially in a humid climate. That being said, improving the insulation is a no-brainer and you have come up with some pretty creative solutions to retrofit it into a traditional house. It's a lot of work, but you strike me as someone who enjoys challenges and problem solving. I wonder if some form of attic fan system might help with the airflow in the summer. Probably not one big fan, but strategically placed smaller ones, maybe linked to temperature/humidity sensors. Thank you for yet another interesting and informative video. I really enjoy how hard you work to keep the aesthetic of the traditional Japanese home, yet make it work for the 21st century.

[@TokyoLlama]

Thanks Michael. We're definitely on the same page here. Especially once the roof is insulated I think we may need some sort of fan to get the air moving, especially on still days. Love the idea of sensors to automate the process!

I would think that some company would see you as an ambassador of sorts to those who look to buy and fix up their own akiya. Also a language and terminology coach, and a tester of locally made building products and tools. You could help fund any more work on the house and/or get materials and tools for testing out and reporting your results and opinions of that product. Just some food for thought. Great job as always.

Thanks, great ideas. Definitely paths I’d like to explore. I did get sent a free tool recently that I’ll use and show in an upcoming video. The terminology is a big one as lots of similar words that mean slightly different things.

Modern Japanese houses can also be bloody freezing in Winter. Ametalin foil sarking is recommended in the attic to give relief from radiant heat from the karawa in Summer. Huge difference.

[@rsmith02]

The radiant barrier foil would have to go under the roof with airgaps, and with all the framing coming through would be hard to do well (lots of holes). On the floor it would do nothing as once it is dusty there is no more reflectance. Just standard insulation would do better and not have a penalty in the winter. In general, for homes radiant barriers are a scam.

@@rsmith02 I ran mine bottom face of the rafters, in the attic and in the cathedral ceiling. Foil tape overlap. The result was the elimination of most radiant heat into the attic. Cathedral ceiling areas comfortable without air con in Summer.

I thankfully found a reinforced baseball cap to protect my head when working in the framework in my house. I am super interested in the new sliding doors we do have triple glass windows here in Germany. Great windows but the glass weight is ridiculous, my door to the balcony has a weight of 220kg.

Thank you for continuing to update us on your progress! I love how you post so gradually that I'm always extremely excited when a new video comes out. Good luck with further renovations I hope it goes easily enough for you :)

[@TokyoLlama]

Thanks very much!

[@BeardyBaldyBob]

I find myself very often looking at Japanese abandoned houses online. There are a few crackers I've seen that if I had the money would love to go for. There is a lovely big place that also has a sake brewery building and about 6 acres of forest land that is about an hour outside Kyoto I saw last week that was beautiful! Already has an offer on it and I'm not surprised.

the thick insulation under the roof with the air gaps all around should also help in the hot and humid summers and not only in the winter. Excellent Job on your house

[@TokyoLlama]

Thank you!

[@Shogoeu]

Can you re-make your "Winter in a Japanese House" video after the insulation and show us how it went?

[@TokyoLlama]

Yes, I plan to show the differences next winter once I get the new windows and more insulation in.

[@justbruh1823]

I was so happy when I saw the notification of your video! I'm always looking forwards it and to see the progress!

[@shahadahshaharudin]

i just watched your renovation vids from 1st until this one in 1 day 😅 the yuzu jokes among others dad jokes is really funny 🤣 don’t wait too long to for next vids and can you do whole house tour and shed more because now it’s almost all done

[@TokyoLlama]

Awesome! Thanks. Will do a tour just after I finish a couple more things, but soon!
