Get an IR camera, if you try a different insulation method on the next exterior wall take a look at both walls with an IR camera. Visually it should make for an interesting YT video.

@pillarz 2 года назад

Not sure if anyone else has mentioned it, but a suggestion from me would be to pull some data cables through the walls while you have the plasterboard off. More and more home devices are trending towards being "smart" or network connected and some will always perform better via a cable rather than Wifi. It may not be as useful in a bedroom, but in the living spaces and office space data cable could be extremely helpful. It can also just be left in the wall instead of presented if you don't immediately have a use for it. Love the videos, keep it up. Marc.

@davesmulders3931 2 года назад

Wifi works great since the AC standard so ethernet cables are obsolete unless you need to connect a small server park. Wouldn't bother in a wooden/plasterboard house anyway. Here in Europe we live in houses with 30cm rebarred concrete walls, and HR++ glass. They actually limit your WiFi, but these types of builds do not.

@texasproud3332 2 года назад

@GatorBird22 2 года назад

Excellent idea. Purchase bulk Cat 6a cable and run a couple lines to each room now. Anyone who says you won't ever need cables is ignorant. Modern wifi still isn't capable of serving even a fraction of the bandwidth. You can route all cables to a central location where you now have an abundance of new network options. Even if you don't need a whole server, you could setup a simple data backup system that you can now transfer media to at data center level speeds. Not to mention being able to utilize the full speed of fiber internet.

@davesmulders3931 2 года назад

@@GatorBird22 Suit yourself. You do know that modern WiFi has higher speeds than 1G (1000 Mbit/s) cable right? The only thing to consider would be to run 10G lines through the house. You will need a 10G workstation, CAT6a cable, 10G switches, 10G server / synology... ánd a disk array that can actually keep up with higher speeds. Leave one component out of that chain and WiFi is just as fast. I edit a lot of video and I work on a local SSD, then synology just mirrors the files to the server on it's own pace. I have a full 10G network and a very fast disk array.... but it's still too slow to work on it directly. And although the mirroring is obviously faster over 10G, 1G would do just fine as you don't have a constant stream of changes during the whole day. I find 10G expensive for the benefits you reap, and by the time it will get cheaper, then WiFi-6 and 802.11ax have taken off and will still about match the 10G corded solution. So yeah, I don't see the use for corded as it would only make sense in a datacenter/server on which multiple people are working on simultaneously. I get the sentiment though. I used to be the same. And each to his own: if you have a better feeling with a cable, please go for it. Just don't say it's far superior to wifi, since it's not.

What an interesting video. I live in Ontario, Canada and watching this video, and then reading comments bringing building code from all over the world makes me realize how strict our building code is here. Im a builder in Ontario and we wouldn't be able to do what Scott has done here, even in a reno. Not knocking the work by any means, just interesting how different it is. Our building code and the research I have done shows how important vapour barrier is. A few things, though. It HAS to be on the 'warm side.' Meaning when heating your home, its cold outside, warm inside, so it is installed on your studs before drywall (plaster board). It CANNOT go on the cold side, behind your cladding, because that allows moisture into your wall cavity, insulation, etc and will breed mold and decay. Also you can't have 2 vapour barriers, inside and outside, this traps moisture within the wall cavity and makes a mess. When Ontario brought in mandatory 1" (R5) exterior insulation a few years ago, people onstalled it without enough knowledge and some used a product that had an outside vapour barrier. This then created the double vapour barrier and ruined a lot of homes. The exterior wrap or 1" insulation board needs to breath, we use Tyvek, similar to the product Scott used before installing the first round of insulation. Most importantly, we treat the home as an envelope and believe that the tighter that envelope (the least amount of air movement from inside to out), the better. And the tighter envelope is more important than all the insulation in the world. Small holes/gaps allow air exchange and renders the insulation almost invaluable (to an extent, obviously). We hen have HRV's (heat recovery ventilators) to breathe for our homes mechanically, as you need air movement, but in a controlled manner. ... sorry, that was a lot. Love the videos and the different perspectives!

@justinkael3255 2 года назад

Living in California, we remodeled our old 450 sqft cottage and added another 500sq ft. It didn't have exterior wall insulation in the old part. We ended up removing all the old redwood siding (along with all the lead paint) and doing osb shear wall, tyvek wrap, hardie plank (cement board) siding and pink insulation in the wall cavity. The combination of lead paint, straighening out some out of plumb walls and matching the addition siding; made it make sense to reside the house. Also spray foam insulation was prohibitively expensive. Its a very clever system you have come up with! Looks to be very economical too! Also, just an observation: It looks like your citrus tree in the intro could use a bit of fertilizer. The yellow leaves with green veins is chlorosis, usually indicating iron or magnesium deficiency. Any all purpose or citrus fert will fix it right up. Here in CA, we have to fertilize 2-4 times a year (depending on soil conditions) to keep citrus happy and productive. Enjoy your vids! Cheers!

R15 with 2x4 walls is standard recommended in zone 4 in the USA. In countries where the SI system is generally in use, the R-values will also normally be given in SI units. This includes the United Kingdom, Australia, and New Zealand. I-P values are commonly given in the United States and Canada, though in Canada normally both I-P and RSI values are listed. International System of Units (SI) while those in the US (based on measurements in Fahrenheit as opposed to Celsius) are approximately 5.71 times those measured using SI. So if that is true R15 in the USA = R2.62 in NZ

The pdf here shows R 20 as the wall value for US Zone 4. insulationinstitute.org/wp-content/uploads/2015/12/IL-2012.pdf

@BTroyPhoto 9 месяцев назад

Canada would be the same Rvalues as the States. Our code in Ontario (some of the most strict building codes) requires a minimum of R22 in above grade walls, R20 in below grade walls, R31 in cathedral or flat ceilings and R60 in traditional attic ceilings. This equates to RSI of 3.87, 3.52, 5.46, and 10.56 in order. I would argue though, that the way Scott has installed it isn't a true R2 in the first method, as he didn't install behind the 'noggs? Thus leaving a cold space. Not condemning that, he always does the best work possible. The next layer on top covered that, but the whole system wouldn't be effectively rated to his quoted, R3 I think he said. And yes, I know he's renovating and that's different. Here in Ontario, our corners are framed open too, so you can always get insulation into the corners and we would install 6Mil Vapour barrier before drywall (gyp board, plaster board) too. Love these videos

@slooob23 2 года назад

I've been insulating/renovating my 100+ year old house in NZ for some time now, here is what I've found. Insulation improves things a lot but will not work anywhere near its full potential if air gaps in the house are not dealt with. The Insulation stops heat migrating through ceilings and walls but does not stop that warm air escaping through gaps. Even small gaps move a huge amount of air in my experience. The worst areas are behind window/door reveals, around skirting boards, and especially around the perimeter of lowered ceilings. Pay particular attention to previously renovated areas that were not finished well. The other issue (in my case) was hollow walls that had timber sarking both sides and no dwangs. The ceilings were lowered but the walls are hollow well above the lowered ceiling and they act like big heat radiators in the roof space. My solution was to pull off a few sarking boards just above ceiling height in the roof space and tightly fit pink batts atleast 400mm down the wall cavity, further if possible. This made a huge difference. Expanding foam has also been very useful in many areas. Wall cavity moisture in exterior walls is a concern after insulation, I'm going to reclad my house on the worst weather wall and use a cavity batten to separate the cladding from the wall cavity. Your idea for a 20mm air gap is a good one in my opinion, if the insulation gets wet it will become a big problem, so it makes a lot of sense. It can be tricky renovating old houses but can be very rewarding work turning something old into something new again.

@drooplug 2 года назад

You are 100% correct. Stopping air flow is the number one priority when insulating. Many insulation products, like glass wool, lose their r value when air passes through it. The same is true with water.

@frankryan2505 Год назад

Yup.. airflow matters much more than people realise.. A lot of the facade work (metal cladding)I do these days specifies taped seams/penos.

@jonnyward5315 Год назад

After spending a year doing a renovation of a 100+ vila. I would agree that getting the moisture release is very important. I’ve tried a few different approaches. But think my new strategy of pulling off the weatherboard. Putting on rigid air board with taped joints, then cavity battens, then massive R value insulation and new gib is great. But better is RAB board and insulated plasterboard. Its not a precise science though. Whatever works in terms of cost, time and effort

At the same time houses without a heat exchanger can be too tight…”sick building syndrome”. Does he plan to install one? If not I wouldn’t worry about a little fresh air migration.

In the UK, a timber framed building would have the cavity filled with a PIR insulation with the best practice being it fitted with a product like gapotape. Then externally you would have a breathable membrane, then counter battened to allow airflow, then your cladding.

@tonyquinlan7341 Год назад

Exactly the same in Ireland with vapor barrier inside, also if using fiberglass insulation vapor barrier keeps fiberglass insulation particles from interning the building.

R is expressed in Watt and square meter. So I guess the American system is different since they measure everything in body parts.

Apparently countries like US and Canada (as opposed to Europe, New Zealand and most others) does not use RSI, but an imperial variant: R-value (in I-P) ≈ RSI-value (in SI) × 5.678263 RSI-value (in SI) ≈ R-value (in I-P) × 0.1761102 From Wikipedia: en.wikipedia.org/wiki/R-value_(insulation)

This seems like a good system to give better conductive insulation while maintaining drying potential! It’s not perfect but as Hemingway said “Now is no time to think of what you do not have. Think of what you can do with that there is” Scott, do not forget about the convection heat losses. In a old house like this the wind can render the conductive heat resistance useless if all the heat gets blown out of the house by a breeze. Different researchers arrive at different numbers but a conservative estimate seems to be that 30% of the energy used for heating and cooling come from air-loss. The best way to reduce convective heat losses in your climate and house is to use drywall as an air-control layer. If the walls and ceilings are drywalled with an airtight connection it’ll greatly improve the comfort of the house. Make sure that all the electrical boxes and heating ducts get’s seals to the drywall and are airtight. It can occur great air-losses from electrical boxes and plumbing. Use expandable foam (in a can) to seal the internal wall cavity from inside the attic space. Also, check gaps and holes in cavity sliding door pockets from above. Internal wall sliding doors can contribute to significant air leakage. The trickiest connection to make airtight in your house is between the floor and wall. The easiest method is to use Spray Polyurethane Foam to seal and insulate under the floorboards. This is not a DIY job. Furthermore the framing and drywall should get caulked to the floor boards, then you should have a good system. Just don’t forget that a house needs ventilation. But this should preferably be handled by mechanical ventilation with heat recovery. The essence of what I am trying to communicate is the with not a lot of economical investment you can greatly improve the performance of your house. It’s about paying attention to the details of how every penetration and connection gets handled. There is an Australian company called Efficiency Matrix that also has a youtube channel that have a lot of great information applicable for you and the details you should implement.

In the process of doing something very similar in our upstairs room of our 1973 house (Melbourne). It was a metal roof -> 5cm air gap -> drywall. HOT. At 37c, the metal was way too hot to touch, and the room was an oven. We can get mineral wool here, so used that and a reflective wall wrap to try and repel some radiant heat. Sparkie's been to fit extra sockets and a run a data cable, so just need to get the drywall back on now.

@janisberzins3939 2 года назад

Mold between the plasterboard and vapour barrier can manifest only if enough moisture can form in that particular spot. And that can happen only if the insulation thickness is insufficient. Warm air from the room meets cold vapour barrier surface and water steam transforms into condensate. Mineral type insulations (glass wool, rock wool) require vapour barrier because of their poor capabilities to diffuse moisture (they soak up water very good, but drying out is a pita), plus every percent of soaked up moisture drops their R or U values dramatically.

It had no insulation anywhere in the house at all. We gradually insulated all of the house as we could afford it. The house and garage are now well insulated and we are so pleased with the result; we heat/cool with two ductless heat pumps and a forced air wood furnace. Our insulation efforts and dollars are "money in the bank" because our heating and cooling are contained within our envelope and are not lost to poor/no insulation. Watching your videos make me want to go back to building work.

@turtlehomes411 2 года назад

Currently doing a 1930s Bungalow in the UK. We’ve built a stud frame 100mm in from the existing wall. We’ve then wedged a 100mm layer of insulation in between that and the frame so that we have no thermal bridges and then packed the frame out with insulation. You are right to be concerned about moisture when insulating internally. Definitely want to use a vapour open construction like you have so moisture can escape to inside and out. We’ve used Steico Flex wood fibre insulation, not sure if it’s available in NZ? But it’s great! 1. It’s not itchy to install 2. You can just cut it with a normal saw 3. It has thermal mass so takes longer to heat up in summer, insulating better from the heat 4. It’s denser than most insulation so has really good sound proofing properties Another alternative we looked at was sheep’s wool however that was a little more expensive and didn’t have as much going for it. Also using a wood wool plasterboard and lime plaster on the wall to keep things vapour open. Has meant we haven’t needed any vapour control layers etc

@caveweta 2 года назад

Scott, get some wool insulation in the ceilings, best R value and supports NZ wool industry. Our wool insulation has been fantastic.

@pongo2k 2 года назад

Its fun to see the different standards and codes around the world:) The "Tek17" codes we use here in Norway now calls for 20cm insulation in the walls, and about 40cm in the roof. We also use the vaporbarrier and outside windbreak/Tyvek witch is also taped against all the openings (windows, doors, vents and pipes etc.) to make it close to airtight. Add that to the tripple glazed windows and its nearly a passive hous. We also mostly use Rockwool or glassfibe insulation.

@dougtooo 4 месяца назад

I use full sheets of firm foam board (what ever thickness you want) secured to the studs and then put drywall directly on top of the foam. The drywall is screwed into the studs as normal. This gives me an additional thermal break and sound break.

Here in Denmark we also have R value, but its most common calculated to U-value. Both is an expression of how much heat escapes through 1 m²(cubic meter) of the construction at a temperature difference of 1 degree between the exterior and interior of the construction part (W/m²K). Where as R is higher the better, U-value is better the lower. We also have some pretty high isolation standards in our building regulations. Currently for a newly build Class 2022 house, you need at least: 455mm isolation in the roof, 335-300mm in the walls depending on it being bricks or wood or another "light" material and 300mm in the floor. It wasn't that fun being an apprentice, cause you would do all the isolation where I was an apprentice.

@edwardharlem9588 2 года назад

Same with the U-Value in Switzerland. Almost a half a meter of insulation for the roof is impressive! I think new builds here have to be U 1.6 or so, that makes about 200 mills of styrofoam on the outside walls (Usually still a classic plastered styrofoam on brick build, which isnt my favorit, but the cheapest unfortunatly)

@janisberzins3939 2 года назад

There's imperial R ratings as well, but there's no easy calculation between the two. R3.0 in the walls, and R6+ in the ceiling and underfloor will make you super cosy and that heat pump will hardly have to work to keep your place warm. I'm in Canberra where it get's down to -5C and now that I've managed to get everything (except the walls, currently R1.5) upgraded, our heat pumps are only set on 18C and we are comfortable year round.

@Yeah73415 2 года назад

With Canberra is that the preferred combo? I think I've got r2 in the walls and r3 in the ceiling. I'm looking to upgrade and was interested in which r values you'd use for the 40 to -6 temperature ranges we get?

What I have gathered from being in the industry for over 20 years(mostly home renovation in the north east UnitedStates) and watching building channels from around the world is that vapor barrier, and insulation detail are very climate dependent. Methods that work in dry climates aren't the answer for wet climates, which may not be the answer for a cold climate or a mild climate. Your best resource would be from local builders. Typically high end builders will be a better source of info because they with the budgets to implement latest technologies and methods. Maybe also look to see if there are building organizations/groups/clubs. They maybe able to point you in a good direction and offer good localized information. Matt risinger is a good source of starting information, but he based out of Texas, which is a hot dry climate. He methods may not transfer to well or be as effective in the south island's mild climate.

@pqrtxs 2 года назад

yeap, everything related to insulation and barriers is, and more, the structure also, the materials and so on. Where I live the the state agency in charge of the building domain, will regularly publish standards for everything, that contain all the coefficients needed for the builders to calculate their wall loads, girder loads, roof loads, wall thickness and so on, so that a minimum is reached in all concerns, since we are in an earthquake prone area, as well as snow and winds, so there's a lot of shits to take into consideration, hence only in the past 15 years the modular wood or metal building actually came into the market.

Vapor drive - nature always finds a balance. Here in SW Florida we have wicked high humidity year round, so the vapor barrier is on the outside.

@bobloblaw10001 2 года назад

Parts of Texas are very humid. Austin is on the boundary between the dry part and the wet part so in the same week it can be as humid as Houston some days and bone dry a few days later.

@@bobloblaw10001 Risinger 'The Build Show' there in the Austin area is a very big proponent of building NRG efficient homes. He is a big proponent of the zip system, which keeps the moisture out, and then uses air purifying/humidity controlling equipment on the inside. He gets grief in comments that the products and materials are too expensive for the average consumer, but he is a good source of information if your goal is to build an NRG efficient home.

@alangreen7974 2 года назад

Hey Scott. I work in building physics research, so can help answer a few of your questions... - Yes, in the US they use imperial R-values (ft2 F h / BTU), whereas we use metric R-values (m2 K / W) almost everywhere else - You are right about vapour barriers too. They are typically only a good idea in regions with harsh winters and very mild summers. The general rule of thumb is to place the most resistance to vapour transfer on the warm side of the insulation - this avoids condensation. So in cold climates, a vapour barrier can be installed on the indoor side of the wall, but in more temperate and/or variable climates like we have in NZ and Aus., it's better to allow the wall to dry in both directions. - I don't see any value in installing the strips of building wrap on the indoor side of the frame either - if it was me I wouldn't bother. - If it were me, I probably wouldn't bother installing the membrane between frame members, or establishing the 20 mm cavity, either. The membrane is unlikely to be very effective as an air barrier, vapour control layer, or back-up waterproof layer when it is so discontinuous. If it's standard practice in NZ it's probably worth doing though - maybe I'm missing something. Thanks for all the great videos! I'm slowly renovating a house of similar vintage myself - I'm always interested to see how you're tackling each challenge.

@kimandersson5344 2 года назад

In Sweden we have plasterboards for the outside closest to the studs then thin wood for air gap and nailing the weatherboards in my 60's house they had boards called asfa boards closest to the studs (same idea just older version)

@BeronV 2 года назад

Interested to see how you’re going to solve the issue of your window reveals. Seen as you’ve effectively created a service cavity but the windows obviously weren’t set up for that initially. Maybe a two piece architrave that wraps into the reveal as well? Would be hard to make it look nice though, with quirks etc.

@stevehastings2010 Год назад

You are sealing and insulating your house. If you don't already have it, I suggest a Heat Recovery Ventilator (HRV). My home has an HRV and I love having fresh air all the time, even during very cold or very hot weather when we keep the windows closed. An HRV brings in fresh air and dumps an equivalent volume of stale air from the home, and it runs the stale air and fresh air through a heat exchanger. So if it's below freezing outside, and your house is a lovely warm temperature, you aren't dumping all the heat outside when the system changes out some air. Same thing in reverse if it's really hot outside.

@ritchiebudd3758 2 года назад

100% would use celotex foam insulation and insulated backed plasterboard this would reduce thermal bridging and for the same thicknesses would be R5.2

@luciflash 2 года назад

Celotex isn't vapor permeable, so the moisture would be trapped. For wood buildings you need permeable insulation.

@becmartin2463 2 года назад

I saw a video of you doing this for someone else’s house a while back Scott, thought it was brilliant and when we did our kitchen reno recently we did the external walls just like this (but 2.2, we’re in Melb & don’t need the extra). Thanks to your great idea, we can stand to be in our kitchen in winter 🙏😃 Cheers to you.

@jronnblom 2 года назад

The same method for trying to minimize cold areas are used here in Sweden as well. I did my garage with 195 mm and 45 mm of insultation. Since Im particular about what I put in my walls I use wooden fibre instead of glasfibre/rockwoll. About the same U-value as glasfibre. And we dont use R-value.

Closed cell spray foam will give you the US equivalent of R-22 on a 6" stud. That would be R-4 in NZ.

@kschleic9053 2 года назад

If you can't remove the exterior cladding, this seems like a good solution. The only thing I would have done differently is to tape over the studs to seal the housewrap sections between the studs to each other so that I had a continuous air barrier. It seems like it might be less work than applying the stripping over each stud too.

A typical US 15 wall system is min 1/2 " osb with tyvek sheet over 2x4 4 framing with 3 1/2 batt insulation and then plasterboard.The insulation can be glassfibre of mineral wool. I prefer mineral wool. However, if you can afford it, Get a closed cell spray foam specialist to come in and lay down a min 2" sealant coat and then put you usual insulation in. The sealant coat hits all the air gaps and then you have a airtight envelope. I do watch Scott Rissenger's channel and generally agree with him. He's a builder, I'm an architect.

@timothyjamieson1282 Месяц назад

The supply issues are mostly due to Fletchers strangle hold on the building industry here. Partially, Govt owned and controlled Gib board through Winstones and also Pink Batts. Hence, it's almost impossible to source alternatives here. Cool way of doing the double layer insulation. Ive seen similar trials done in Scandinavia with excellent results. The key is offsetting the studs etc between the two layers.
