You may not think that you have the right skill for all this insulating process Shoyan but it seems to me that, when it comes to building construction, you can 'turn your hand' to anything & make a success off it. I admire your skill & application to the work at hand. Well done my friend. Cheers, Don from South Australia.
This type of airtight sealing, at least in the Netherlands, is not for cold outside air coming in, but to prevent condensation inside your walls, since the temperature in your home is usually warmer and more moist than the outside temperature, and when air cools it can contain less moisture and condensates inside your walls. If your outside wall is sealed as well the moisture cant escape and will make it so your wood and insulation start to rot and fungus will grow.
Not only that, but wet insulation material loses it’s insulating properties, leading to worse efficiency.
It is for both, skiing down the hill with your ski jacket open doesn’t keep you very warm.
Insulation without air ceiling, significantly reduces the effectiveness, There’s a reason passive houses require maximum air changes an hour.
I mean look at the greenhouse, basically no insulation, but still relatively warm for a fair a while after the sun sets, because it’s relatively airtight.
Japan definitely has issues with moisture through the summer months but I don’t think it is common practise to build in this manor. It most likely relates to passivhaus, in particular energy efficiency/ performance. It is easier and cheaper to manage temperature in an airtight building
The negative is of course that it stops moisture from passing through the walls, ie. breathing. This effectively means that active air conditioning is needed inside the house to prevent build-up. Poorly designed houses with membranes can therefore lead to issues if the electricity is cut off. Essentially such houses may need to be warm all the time.
@@Virdae from what I've seen on the latest tech is that there has been semi-permeable membranes that you can put into the interior of the walls, which will allow for breathing and actually modulate itself depending on temperature. Intello Plus is an example.
Interesting, in Sweden we use a similar membrane but to prevent high moisture air from the inside to be pushed into the walls and cause condensation inside the walls. Love your videos they keep me inspired to work on my house! :)
Oh... Glass fibers are very bad for lung health. The fibers are almost as light as air, so please wear a respirator mask to avoid lung problems in future! Please be safe, so you can do many more wonderful homes!
Also, I appreciate your cutting the insulation batts longer. Insulation settles over time, from vibration, and thermal changes. So having the extra length, prevents gaps at the top of the wall forming after 10-15 years. It means the insulation will stay efficient for an extra decade on average.
In old houses they didn't have the tape, plastic barrier or R-value, which is why we are freezing in the winter. 🥶
With this uber-air-tightness, I think that it is imperative that an air-to-air heat exchanger be installed. Without, the house will be so tight that odors, etc. will linger. The heat exchanger will allow purposful venting of air, while saving the energy by warming/cooling the incoming air with outgoing air.
This is great, the first properly insulated and air sealed Japanese house I've seen! Love the attention to detail. I'm looking at a smart membrane that passes humidity 透湿シート for my own project.
Oh he really should be wearing a Tyvec suit, nytrile gloves and a mask when working with glass fiber insulation...
You are totally right, mask is the most crutial in my opinion.
Yeah he’s definitely not one for PPE.. each to their own 🤷🏻♂️
Jag håller med 😷🔨🪚 i Sverige har vi jobbat med dom materialen länge🙂
Hey!
Just a quick tip.
The insulation is really bad for your lungs, so wearing a mask is super beneficial.
Keep up the good work, i love the craftmanship!
Cheers from a carpenter from Denmark! :)
Please wear a respirator when working with glass wool
All that beautiful wood and workmanship being buried forever, never to be seen again.
Dayum always nice to see a new video from the one and only
I love you guys. You do great work.
What a wonderful thing to wake up to :D You make isolation look so neat and tidy
Very therapeutic and useful!
Another interesting insight to your skills.
These videos give me hope in carpentry
Thank you for your kind videos I learn something every time I see them thank you!
Always good to learn new skills Shoyan, thank you for the video.👍👍
very informative videos, nice
Another fine example of your craftsmanship sir. Awesome! 🙇♂️
Amazing - please continue doing videos I really like them
Très beau travail merci de le partager avec nous !
This is going to be a warm and wonderful home.
All the way from Long Beach, California: Thank You
Thank you for sharing your process with us. Everyone stay safe,warm, happy and healthy. From Henrico County Virginia
Loved the way you tackled the insulation especially the air membrane plastic sheet the details is outstanding but one thing amazes me it the shine of the timber.😀👍👍
Always impressed, Shoyan, by you striving to learn and do new things in your trade. Thank you so much for sharing your work with us!
Arigato Shoyan San, great job on the insulation, and I hope you and your son didn't suffer too much from itching, fiberglass is not nice to the skin or eyes and lungs, take care my friend, I look forward to seeing your next video, stay safe, best wishe's to all, Stuart Uk.
I appreciate watching the attention to detail and such excellent craftsmanship. I would love it if Mr.Shoyan came to Utah to build me a house…. Maybe one day
Always a pleasure to watch work done with care and attention. The end result looks excellent!
Wish we have that level of quality here in the U.S
I knew about preparing to be efficient at the job site, so I did not anticipate the silly behavior when time allows. I guess it shows that being practiced and prepared frees up time and energy to have fun.
Excellent job! Careful work and very precisely accomplished! Well done! よくできました！ 丁寧な作業で、とても丁寧に仕上がりました！ よくやった！
Tack!
Nice work! We have 600mm insulation on the ceiling and 250mm in the walls here in Finland😅 We use plastic as well keeping the condensation out from the wall. There's a moisture point inside the wall where the warm and gold air meets. Keep up the good work you two👍🏼
Vi har samma i Sverige 😊
I hate fiberglass insulation !!!!! I would need a mask, tyvek suit, and gloves !!!
I did some insulation recently and opted to use sheep wool. It isn't as good as fibreglass but I picked it so I could avoid itching like buggery for days 🤣
Love how the pencil barely moves from his mouth, true sign of a wood wizard!
my father is a carpenter in canada, where ALL houses has fiberglass insulting whool. The trick to not get itchy is tu rub corn starch on your skin before you start the work; it fills the pores and prevents the glass fiber from sticking in yout skin and being itchy.
0.4 air changes per hour is a very good result, passive house standard is 0.5, good job :)
I'm French and I'm amazed that we have more or less the same standards between Japan and France. When I saw the ISOVER logo, I was impressed. Your work is precise and remarkable. But I really don't like plastic in construction. It's not a noble material, and the logic of making partitions watertight, if you can understand it, poses a lot of problems. Waterproofing encourages damp spots, and if there's a leak, everything's damaged before you know it... Nothing's ever perfect, but my 220-year-old house is made of cut and rough stone, earth and wood, all with lime. And its longevity is a source of inspiration for me. Thanks again for your work, I love your channel :-)
It's Japan, 2 things they account for when building houses is earthquakes and typhoons, hence the waterproofing, this is a newer house so it will rely a lot more of the air conditioning as opposed to older houses like machiya kyos which had passive ventilation
This is not the standard in Japan. Most homes have no such membranes and hardly any insulation.
cant believe all the pretty timber framing is being hidden
This is the same as a Japanese saying: «I can’t believe that the two by fours are beeing hidden, they look so cool». For them and their culture, thats just how they do it.
3:00 priceless 😂😂😂
I highly appreciate these videos and i have big respect for the work and knowledge that is shown from this channel. What i dont like is the fact that so many modern, yet environmental-unsustainable products are used. I know that these materials are considered "state of the art" when it comes to effectiveness, like insulation, glue power and stability.
I am specifically talking about chemical foams, chemical glues, industrial-produced insulations, chemical coatings etc...
Those materials might result the desired outcome, but makes the whole house a Hazardous waste dump in the future + can cause health issues for the people who live in these houses.
5 it is not sustainable in the long term.
Its a difficult situation, since natural materials have become so expensive, its hard to afford.
But nevertheless:
I dont think we favor ourselves by compromising and choosing materials that are unhealthy to humans, dont last for many generations and cause big problems concerning disposal & recycling.
Nice video.
Just the idea of glass wool made me itch.
My grandfather could bathe in glass wool, so to speak, and it didn't bother him.
♨️Awesome♨️
God Bless ❤
🙏🏻😇🙏🏻
In Norway, we use 300mm insulation in the roof and minimum 200mm in walls.
Is urethane spray foam allowed in Japan? Looks like it would be a good product for due to the large open stud bays.
The most itchy task in carpenter when you work with glass wool to insulate the house, specially the ceiling part..
Pet hair roller before a shower always works for me
Anyone know what the panels are that go on the outside of the wood?
Is it not itchy? The fibreglass insulation in Australia is quite itchy, I usually use a mask as it is horrible to breathe in, and cover-all suit. Or get the apprentice to do it haha
Edit: ahaha I just got to the part where you say it is itchy. Very tidy result at the end. 👏👏👏
You just know that when bags of wool and not the polyester insulation turn up that the knob who organised it had no intention of installing it 🤦🏻♂️🤦🏻♂️
Are the wall studs over there, spaced 40.64cm(16in) like in U.S.?
❤
Hi, thanks for your videos 😊. I'm living in Sardinia (Italy) and I'm owner of a wooden framed house as well. Here climate is very hot in summer. I was wondering how do you cope with very hot weather you have in certain Japan regions. Despite the insulation you are using, (in this particular video fiberglass or foam panels in other), with good thicknesses, they have relatively low mass, and a framed wood house has low mass too. What is the trick Japanese carpenters use to increase the thermal lag of a wooden framed house?
In my house engineers decided to use insulation that has much more mass comparing with FOAM. Outside I have a coat insulation made by high density wood fiber and through the studs insufflate cellulose which has good hot weather insulation characteristics... Please let us know I'm very curious...
I'll be waiting for your next video! 👋
The mass is mostly irrelevant, the R value is the key. If you want to cool it you use a ductless minisplit which were invented in Japan.
Fibreglass insulation itches like crazy 😯😯😯😯
yep
Not all of it does! I did some work for a chemical engineer at Owens Corning that told me the main part of fiberglass that itches is the dyes in the glass wool, not the fibers themselves! And truth be told, the un-dyed fiberglass insulation definitely itches way less than the pink, yellow, or "premium" dyed stuff!
Fiberglass SUCKS Shoyan! Leave that stuff alone! use gloves and respirators for your lungs. in either case you will hate it after. It is not safe for your lungs nor is it safe period. We hate it here I have not done it in a few years except one or two bays of studs
is there anny reason why you use Glasswool instead of Stonewool? it would prevent the intchiness while installing.
A very neat job as always - but please wear a mask, gloves and eye projection.

The fiberglass dust doesn't bother your lungs?
Почему у вас дерево такое красивое?🤩
Грязная, тяжёлая работа. Но как говорят в России - "Чем грязнее руки , тем чище деньги ".
Благодарю за информацию и ваш трад , поллега .
What is the R value ?
Maybe around 30.

Es muy importante utilizar mascarilla porque si no tragas fibra de vidrio y es muy peligroso..
please wear an respirator!! if those glass fibres get into your lungs, it can be bad for your health! long sleeve shirts and trousers and a facemask!
Ich halte nicht viel von dieser Dämmung. Sie bietet keinen hohen sommerlichen Wärmeschutz. Bessere Ergebnisse erzielt man mit dämmstoffen hoher Temperaturamplitudenzahlen wie Zellulose oder holzfaserdämmung.👍👍🇩🇪ein zimmerermeister.
No power points or down lights? Wear a mask when handling Fibre glass and overalls.
I hate working with fiberglass. it's got to be one the most dangerous products..
