In the US, we have a similar grading system, except that treated timber is generally referred to as "pressure treated" lumber. Sometimes, we'll use the the specific grade designation like marine grade. The other difference is the color. All of our lumber that is the equivalent to your H2 is green in color. Borate treatments are usually done after framing is completed. A team will use hand sprayers to treat the bottom two feet of the exterior walls inside and out with termite solutions.

Not fully correct around the treatment process. Firstly the timber is steamed to open the pours (remembering that pine has very open pour and grain pattern) secondally CCA treatment is one of the safest treatments around in the around that is used per board. The treatment generally any penetrats around 20mm into the timber. It is then heated again to lock the treatment into the cell walls. Treatment won't leach that often now days. Because of the processes used around the treatment and heating process.
That is some beautiful lumber. I know it varies, but here in the US, in Minnesota, most lumber is pine, and its barely square, knots all over, warped, and looks like crap. That stuff you guys were working with looks fantastic.
No it isn't, its crap, I always call it hoop pine & knotty pine, that chit twists, bows, splits using nail guns if too dry.... I built all my houses with it & framed up quick b4 the crp bent, used the twisted crap for nogs, b4 gyprock (gypboard in NZ) I'd spend a day straightening the walls, planning, cut half way thru studs & hammer timber wedges in to straighten it then flitch plated the cut....... I could go on...
We were building a house near Lake George just south of St Francis,just about the whole framing package was warped returns dropped off for us,really twisted junk.
Here in New England, the studs we use to frame walls, even exterior walls, are usually kiln-dried, but not chemically treated. The termites we have in this area only eat wet wood; same for the molds and funguses we have in this area. So, as long as the builder laps the flashing and housewrap correctly, one can expect the framing to last indefinitely. Of course, that doesn't always happen; we have our share of sloppy builders, But, if they follow the codes correctly, untreated wood works fine here.
Indeed. Here in Maine I hardly ever see green lumber at the lumber scrap yard but lots of natural. My house is all natural, or so I believe, but it's 115 years old so take that into account.
Interesting fact, Radiata pine is native to the west coast of America yet it was never commercially exploited. I work on houses containing 200 year old North American softwoods, no chemicals required. Here in New England your wood has a lifespan of aproximately 20 years....
Was a carpenter in New England for over 45 years. The oldest house I ever worked on was over 250 years old but I also worked on dozens of houses that were 180 to 200 years old.

It's all in the material.
@@tomernest2004 Commercial trees species are not genetically engineered. In fact it has been tried, but the long generational cycle makes it unfeasible (as of today).
Very informative video Josh. Had no idea there were so many grades in NZ. I had to laugh when you spoke about the use of 3.2 (Aussie schoolboy humor). And you're right to be concerned about the disposal of those offcuts. Well done, bro.
Thanks for the answers..... In US to best of my knowledge we only had pressure treated (anything that touches concrete or exposed) & non pressure treated for the rest of the home...... Although new construction these days are using heaps of LVL 'engineered materials & the ZIP System for the side & roof sheathing.
Boron or Boric Treatment is the process. That is why it goes pink in colour. Its just a dye in the solution to tell you that its been treated along with the branding and/or the that is imprinted on the timber.
My theory is the H3 offcuts could be chipped and added as a supplement to the production of particle board. Much in the same way as scrap steel is added into the production process of new steel. The hard part would be organising a collection system for the offcuts. I guess there could be a bin at the local landfill.
It's hard to work with, and particle board can't be allowed to get wet, so I doubt that it's worth the extra health and safety concerns of working with contaminated ship and dust to make something that can't be allowed to get wet anyway.
Kia Ora Josh, this video is really helpful thank you for producing this for us all to learn from. Question if the joists can be made from H1.2 how close can your subfloor be to the ground for it to change to a higher treated wood? For example I'm building a sub floor that's 60cm from the ground should I use H3.2? Instead of H1.2? :)
I'm from South Korea and here are not many timber based house but just all concrete. Thanks for this informative video of New Zealand Timber Treatment.
We have pressure treated lumber here that’s designed to hold up to moisture better than normal timber. the often use it for the bottom plates of a wall, and for other applications.
@@iatsd Have a second read of the actual words in my post and maybe pay attention to what was said in the video. If you still feel the need to repeat the snarky questions, kindly direct them to the content creator. Cheers.
My grandpa bought a b&b in piha nz and fixed it up and added a “dog house” above the garage, basically a little condo with bathroom and shower and kitchen and balcony.
Here in South Africa, our treated timber has a green tint to it. Mostly for fencing posts but treated roof beams can be specially ordered but nor common.
Haha, I thought that I was the only one doing that, except mine are green from Rit dye that is included in the mix. Soaked in Borax and dyed green so that I can be able to tell the difference between the ones that are treated and the ones that are not treated.
I believe h3.2 is often h4 timber that has been guaged or planed and therefore lost some of the exterior treatment. H3.1 seems to be for more visual timbers and lacks the green copper, maybe just chrome and arsenic
I have always wondered this when the builders came to work on the place and I saw pink wood. Silly me thought it was just cos it was easy to distinguish between the type of woods XD
Fun fact: H6 treated wood is done with a chemical called chromated copper arsenate (CCA) which, as the name might suggest, contains chromium and arsenic. In places like docks or wharfs theres of course little public health concern HOWEVER, it was also commonly used for decks and childrens playsets until around 2004. So if you have a wooden structure or deck made of unknown wood, built before 2004, its v possible, even likely that its CCA.
Someone needs to come up with a mill for off cuts and turn it into an OSB panel or structural laminated beam. Also, if your lumber suppliers begin to offer custom precut lumber packages, they can capture the offcuts.
Here in the US and Canada we have blue timber which has been tinted by the fungus which killed the tree in the first place! The fungus gets into the tree on the horns of the Mountain Pine Beetle. I'm pretty shocked to see @5:32 structural timbers (H3.2) in direct contact with soil. I don't think code allows direct contact at all in the US. We recently, finally, got a way to build a code-compliant fence, a steel bracket from Simpson that holds a fencepost with a tiny airgap above the concrete footing that supports it, and can support the moments that fences see.
I figured it was pressure treated wood, though it's interesting to know that the pink is an intentional dye. IME in NA, pressure treated wood is tinged green due to a side effect of the copper & arsenic used. Boron is definitely a bit better than copper and arsenic for the environment and builders who have to handle and cut it.
@@ChrisWijtmans Arsenic isn't bad for the environment? Are you dense? LOL. Boron is an essential trace element for life, arsenic is a toxic heavy metal. Copper is also a potent biocide that can completely ruin soil microbiome.
Great informative vid. Yup, no pink stuff on this side of the ditch but plenty of blue and green. I paint and plastic line my planter boxes, just to be sure to be sure. The term 'copper arsenic' just never sounds edible. 🇦🇺👍
A whole new sub-division had to be abandoned in a nsw town,...( very strange, an abandoned new suburb). There had been a timber treatment plant, before re-zoning.
Great to hear a professional acknowledge the CCA issue. New Zealand is quite unusual still building houses full of toxic Arsenic and Chromium. CCA wood treatments were banned in the US 20 years ago, as they are in Europe and Australia. NZ Govt's actual official advice is to dump it all into landfill.
it’s not great, but better than the untreated stuff they used on the 90s and the natives they used for 100+ years were solid as but that was unsustainable
Pink colour is a dye that's added to identify H1.2 treatment. The green timber you see is treated with copper arsenic and chromium. This is H3.2 H4 etc. Both types of treatment contain salts,heavy salts. This will rust out your fireplace and chimney and neighbours roofs etc.
We also treat wood to prevent rot and insect damage. In the past the treatment used copper sulphate , correct me if that’s wrong. But the copper based chemicals were outlawed (of course) I don’t know what they treat the wood with now.
Chromated Copper Arsenate (CCA) was common in the US but banned in residential construction in 2003. Various products in use now, If you see MCA on treated lumber it was treated with Micronized Copper Azole.
In Canada, at the present time, our treatment grades are untreated, outdoor treatment and constant ground contact treatment. I still have small piles of treated offcuts. Our waste path here for treated wood is essentially “trash.” And of course, special fasteners. Today’s treatments will dissolve the wrong screw. I’m just now framing a small garden house on my property with what we call “SPF” (spruce/pine/fir) and interior framing is not treated at all in Canada. One “benefit” of the tundra over the tropics I suppose… 🤷🏻♂️
The wood framing of a house shouldn't be exposed to water, and therefore doesn't need rot or fungal protection (aside from the baseplate). Seems like an unnecessary expenditure that would inflate the price of a home for little extra benefit. At least here, building a home with all pressure treated wood would add ~30% to framing costs. Termite monitoring/prevention services are pretty cheap, here at least, and you would likely still want to pay for it even with all treated lumber.
In the US our pine lumber for framing houses is also heat treated and chemically treated but its certainly not pink... I find it really odd and fascinating how pink your lumber is. We do have lumber for sill plates and for wet locations that's treated for termites and fungus's but its green. like dark green. The ground rated stuff is treated with with something that turns it a reddish brown.
Its because in nz the old green treated stuff used to have arsenic and copper in it.. Hence the change to pink treated pine. Nz has requirements like this from some scandals in the 80s with mouldy homes, the us dosent have national standards in homes, they should used treated pine for every part of the house
@manchagojohnsonmanchago6367 The US is pretty big. We cover many different climates, in Arizona where I live it wouldn't make sense since we don't have high humidity. We do have local building codes that will dictate the materials used based on the region though.
@@manchagojohnsonmanchago6367 You must be joking, why would Americans use substandard crap like NZ uses. Americans have a lot of choices in regards to the type and quality of the timber they use. In NZ you have no choice but to use radiata pine.
@@funtimesatbeaverfalls? Why am i joking? Canadian and american hones are very very poorly built.. And yes.. Radiata pine comes from america ITS NATIVE TO CALIFORNIA!!!!.. its a bloody crime they grow it in australia and new zealand while brazillians grow australian and new zealand timbers commercially since the 19th century! Brazil even has a straight growing comnercial australian blackbean tree producing excellent straight heavy hard timber that can be grown in tropical and frost free temperate climates. North american gomes are exceptionally poorly built. Their rooves are insane and structurally unsond too, tar paper and plywood things, any storm or heavy wibd or snow cucks them. They should be using corregated steel roofing like australia (not iron, australian sheet is work hardened steel) and cyclone screws and cinderblock and rebar homes, Places like florida or kansas would laugh off those tornadoes and cyclones. Generally i found americas hous production cost is very very low.. A houst in portugal costs with material and labour more than the usa becaus its well built from stone, brick, steel, concrete and terracotta. Its the selling cost, the profit thats higher in the usa
In case your wondering where the pink color comes from They throw hundreds of flamingoes through a wood chipper and that’s where the pink color comes from makes the wood look kooler during the building process like A beach vibe to keep tempers down during construction phase . It’s a lot of flamingoes but balances things out less people getting hit over the head with 2x4s 😂
Most pine lumber in my neck of the woods is just kiln dried. We have pressure treated wood but you're not supposed to use it indoors because the chemicals off-gas and having that inside a home is like hotboxing cancer dust. But we make up for it with our wonderful American diet, lol.
wow, here in the us we dont have any treatment on interior boards other than the sill plates that touch the ground which would be standard cca (basic pressure treated int/ext. Exterior boards (mostly decks and fence posts) either regular cca, or ground contact cca. Anything more than that would be special order, i've never heard of what those ratings even are or where you would even get them. 28 years in construction.
I live across the ditch in Western Australia. Our home was started in 1892 and is mostly Jarrah. Some of the massive beams are supposed to be Marri or Karri? I like the construction of your homes which is "similar" to American construction only done properly. Never made it to NZ, my loss.
Copper Chromium Arsenate complex. Issues with leaching of offcuts and when houses are knocked down. Also use Tributyl Tin Oxides and copper azoles. Not sure which is worse but likely the Arsenic & Chromium if not managed properly which was mentioned and is why it's not used in other countries.
Sorry - many alarmists out there. Don't worry. Once the CCA (NZ wants to phase out) and ACQ (the latter preferred) is locked in the chemicals are generally not reactive and in the wood cells themselves. The valid concern is that copper and/or arsenic overexposure is bad as both cause harm in larger quantities. Those quantity thresholds are nowhere close in approach in finished, treated timber. NZ requires several layers of testing on all treated timbers. Note that CCA does have negative environmental impact issues and NZ is working on getting rid of it. In particular, farming and vineyard posts can leach the chemicals into the ground as the wood degrades - obviously not a goid thing. The term 'treated' is misapplied often - as the process of treatment includes heating-application-reheating-drying - thus leaching above ground (no ground contact) is generally not an issue. Also boron is used in the process and it is an inert agent not harmful (but borer and termites hate it).
New Zealand is one of the only countries that still uses the chemical mix for external timber, you'll find the states and even Australia has banned it in favour of a safer chemical mix. CCA is banned in the states too.
The premise is insane. The world is full of millions of board feet of untreated timber of every species in the interior for hundreds of years that aren't rotting. However, treating to prevent termites is logical and genius.
Having watched the video, I still don't know why it is pink. I liked the little pump animation of it shaking whilst pumping the CCA pressure cycles though, thanks. I mixed borax, pyrethrum and antifreeze, just for good measure and doused my rimu 😢floor boards prior to sealing. They didn't turn pink.
It is pink so it is easy to spot when someone uses it in the wrong place. If you see pink timber somewhere exposed to the elements, like under a deck, someone has stuffed up.
WoW Your Stick Construction Appears A Lot More Hearty And Sturdy Than American Homes. Is It Because Of The Extra Weight Of Snow and Ice? if the US Added That Extra Use Of Timber That I Can See, It Would Make Our US Homes Cost A Third More! Thats A LOT More Timber Than We Use. Seemingly Anyway. NICE!
Always wanted to know if the h1.2 KD timber is treated right through the timber like h3.2 ,or just on the surface, watching the video it would suggest the treatment is pumped throughout the timber?
@@nzbuilder its a surface treatment really and a compromise between wet boric treated timber that screwed builders backs in the 70's and 80's and kiln dried untreated that rotted in houses in the 90's and early 2000's. Technically you are supposed to treat cut ends though I have never seen that done.
New Zealand timber is naturally a dull color, but gets its pink color from the flamingos it eats.
I did not know this. You learn something new every day.

Very informative video Josh. Had no idea there were so many grades in NZ. I had to laugh when you spoke about the use of 3.2 (Aussie schoolboy humor). And you're right to be concerned about the disposal of those offcuts. Well done, bro.
Thanks for the answers..... In US to best of my knowledge we only had pressure treated (anything that touches concrete or exposed) & non pressure treated for the rest of the home...... Although new construction these days are using heaps of LVL 'engineered materials & the ZIP System for the side & roof sheathing.
ICF baby! Never looked back.
It's always funny hearing Australians and New Zealanders talk about decks.
Boron or Boric Treatment is the process. That is why it goes pink in colour. Its just a dye in the solution to tell you that its been treated along with the branding and/or the that is imprinted on the timber.
Fascinating! Great to know!
My theory is the H3 offcuts could be chipped and added as a supplement to the production of particle board. Much in the same way as scrap steel is added into the production process of new steel. The hard part would be organising a collection system for the offcuts. I guess there could be a bin at the local landfill.
It's hard to work with, and particle board can't be allowed to get wet, so I doubt that it's worth the extra health and safety concerns of working with contaminated ship and dust to make something that can't be allowed to get wet anyway.
Great video mate, just subscribed!
great video, answered my questions in one.
Ta. Very good. Nicely produced. Top man!🙃
Kia Ora Josh, this video is really helpful thank you for producing this for us all to learn from. Question if the joists can be made from H1.2 how close can your subfloor be to the ground for it to change to a higher treated wood?
For example I'm building a sub floor that's 60cm from the ground should I use H3.2? Instead of H1.2? :)

I'm from South Korea and here are not many timber based house but just all concrete. Thanks for this informative video of New Zealand Timber Treatment.
We have pressure treated lumber here that’s designed to hold up to moisture better than normal timber. the often use it for the bottom plates of a wall, and for other applications.
Because trees in New Zealand are... gay?
😂😂😂
Just the cheap pine tree's are gay really ..it's not even good fire wood...to much Sapp and blocks the Chimney.

Can you point to any studies about this "issue"? Anything on ground leach rates or combustion liberation? Anything at all?

Interesting bit about the offcuts🤔🤔
Nice video, Josh. I tell tourists that New Zealanders just like the colour pink 😂 After all, we have Pink Batts also.
It’s because it’s pretty!!💕💕💕💕💕🤣🤣
Here in South Africa, our treated timber has a green tint to it. Mostly for fencing posts but treated roof beams can be specially ordered but nor common.
Green is often copper arsenic treatment
Cheers man, the more u know. Helps as a tradie.
In the US pink limber indicates that it is fire treated. Typlcally green or some other color (brown/cedar tone) is for use outside.
This is cool info love this video
Seen a lot of timber in Australia with some sort of green treatment on it.
Now, here in the US, timber and lumber are distinct terms. Timber is cut trees while lumber is milled timber.
Haha, I thought that I was the only one doing that, except mine are green from Rit dye that is included in the mix. Soaked in Borax and dyed green so that I can be able to tell the difference between the ones that are treated and the ones that are not treated.
Always wondered what the difference was between h3.1 and 3.2, cheers, subscribed.
Awesome :)
I believe h3.2 is often h4 timber that has been guaged or planed and therefore lost some of the exterior treatment. H3.1 seems to be for more visual timbers and lacks the green copper, maybe just chrome and arsenic
@@joshb6993 makes sense.
I have always wondered this when the builders came to work on the place and I saw pink wood. Silly me thought it was just cos it was easy to distinguish between the type of woods XD
No termites and no snakes... sounds perfect... and to top it off you've got the "How to Dad" guy. 👍👍👍
Fun fact: H6 treated wood is done with a chemical called chromated copper arsenate (CCA) which, as the name might suggest, contains chromium and arsenic. In places like docks or wharfs theres of course little public health concern HOWEVER, it was also commonly used for decks and childrens playsets until around 2004. So if you have a wooden structure or deck made of unknown wood, built before 2004, its v possible, even likely that its CCA.
Someone needs to come up with a mill for off cuts and turn it into an OSB panel or structural laminated beam. Also, if your lumber suppliers begin to offer custom precut lumber packages, they can capture the offcuts.
The majority of builds are done by larger companies. They all use pre-builts, so it's already beng captured by the manufacturers.
Here in the US and Canada we have blue timber which has been tinted by the fungus which killed the tree in the first place!
The fungus gets into the tree on the horns of the Mountain Pine Beetle.
I'm pretty shocked to see @5:32 structural timbers (H3.2) in direct contact with soil. I don't think code allows direct contact at all in the US. We recently, finally, got a way to build a code-compliant fence, a steel bracket from Simpson that holds a fencepost with a tiny airgap above the concrete footing that supports it, and can support the moments that fences see.
I figured it was pressure treated wood, though it's interesting to know that the pink is an intentional dye. IME in NA, pressure treated wood is tinged green due to a side effect of the copper & arsenic used. Boron is definitely a bit better than copper and arsenic for the environment and builders who have to handle and cut it.
copper and arsenic is not bad for the environment, in fact boron is much worse.
@@ChrisWijtmans Arsenic isn't bad for the environment? Are you dense? LOL. Boron is an essential trace element for life, arsenic is a toxic heavy metal.
Copper is also a potent biocide that can completely ruin soil microbiome.
DEI is very important in NZ.
Kiwi's are building Barbie houses! 😂
Also that external use treated will corrode metals touching it like Zincalume.
Great informative vid. Yup, no pink stuff on this side of the ditch but plenty of blue and green. I paint and plastic line my planter boxes, just to be sure to be sure. The term 'copper arsenic' just never sounds edible. 🇦🇺👍
A whole new sub-division had to be abandoned in a nsw town,...( very strange, an abandoned new suburb). There had been a timber treatment plant, before re-zoning.
Great to hear a professional acknowledge the CCA issue. New Zealand is quite unusual still building houses full of toxic Arsenic and Chromium. CCA wood treatments were banned in the US 20 years ago, as they are in Europe and Australia. NZ Govt's actual official advice is to dump it all into landfill.
it’s not great, but better than the untreated stuff they used on the 90s and the natives they used for 100+ years were solid as but that was unsustainable
CCA wood treatment is not illegal in Oz.
@@nzbuilderwhy are native trees unsustainable?? Do they take too long to grow?
Pink colour is a dye that's added to identify H1.2 treatment. The green timber you see is treated with copper arsenic and chromium. This is H3.2 H4 etc. Both types of treatment contain salts,heavy salts. This will rust out your fireplace and chimney and neighbours roofs etc.
Not even rust. Those are toxic and if they get burnt / Hot you may be exposed to the.
Interesting..
We in europe use green dye for a boron treated plank (or "colorless" coating is available)
Seeing all the cross bracing on the walls of the home being built shows in New Zealand they build homes to last. Those are a very strong built homes.
We also treat wood to prevent rot and insect damage. In the past the treatment used copper sulphate , correct me if that’s wrong. But the copper based chemicals were outlawed (of course) I don’t know what they treat the wood with now.
Chromated Copper Arsenate (CCA) was common in the US but banned in residential construction in 2003. Various products in use now, If you see MCA on treated lumber it was treated with Micronized Copper Azole.
Nice.
In Canada, at the present time, our treatment grades are untreated, outdoor treatment and constant ground contact treatment. I still have small piles of treated offcuts. Our waste path here for treated wood is essentially “trash.” And of course, special fasteners. Today’s treatments will dissolve the wrong screw. I’m just now framing a small garden house on my property with what we call “SPF” (spruce/pine/fir) and interior framing is not treated at all in Canada. One “benefit” of the tundra over the tropics I suppose… 🤷🏻♂️
Boron I've seen it done at CHH saw mill in kawerau
I only ever see green here in Australia. Often enough they DON'T USE treated. So it's just regular pine colour
double brick here in WA
The wood framing of a house shouldn't be exposed to water, and therefore doesn't need rot or fungal protection (aside from the baseplate). Seems like an unnecessary expenditure that would inflate the price of a home for little extra benefit. At least here, building a home with all pressure treated wood would add ~30% to framing costs. Termite monitoring/prevention services are pretty cheap, here at least, and you would likely still want to pay for it even with all treated lumber.
In the US our pine lumber for framing houses is also heat treated and chemically treated but its certainly not pink... I find it really odd and fascinating how pink your lumber is. We do have lumber for sill plates and for wet locations that's treated for termites and fungus's but its green. like dark green. The ground rated stuff is treated with with something that turns it a reddish brown.
Interesting to hear how its the same but different, thanks for watching and commenting
Its because in nz the old green treated stuff used to have arsenic and copper in it.. Hence the change to pink treated pine.
Nz has requirements like this from some scandals in the 80s with mouldy homes, the us dosent have national standards in homes, they should used treated pine for every part of the house
@manchagojohnsonmanchago6367 The US is pretty big. We cover many different climates, in Arizona where I live it wouldn't make sense since we don't have high humidity. We do have local building codes that will dictate the materials used based on the region though.
@@manchagojohnsonmanchago6367 You must be joking, why would Americans use substandard crap like NZ uses. Americans have a lot of choices in regards to the type and quality of the timber they use. In NZ you have no choice but to use radiata pine.
@@funtimesatbeaverfalls? Why am i joking? Canadian and american hones are very very poorly built.. And yes.. Radiata pine comes from america ITS NATIVE TO CALIFORNIA!!!!..
its a bloody crime they grow it in australia and new zealand while brazillians grow australian and new zealand timbers commercially since the 19th century! Brazil even has a straight growing comnercial australian blackbean tree producing excellent straight heavy hard timber that can be grown in tropical and frost free temperate climates.
North american gomes are exceptionally poorly built.
Their rooves are insane and structurally unsond too, tar paper and plywood things, any storm or heavy wibd or snow cucks them.
They should be using corregated steel roofing like australia (not iron, australian sheet is work hardened steel) and cyclone screws and cinderblock and rebar homes, Places like florida or kansas would laugh off those tornadoes and cyclones.
Generally i found americas hous production cost is very very low.. A houst in portugal costs with material and labour more than the usa becaus its well built from stone, brick, steel, concrete and terracotta.
Its the selling cost, the profit thats higher in the usa
They have the same pink lumber in Florida too. Its rot and termite resistant due to the tropical environment
In case your wondering where the pink color comes from They throw hundreds of flamingoes through a wood chipper and that’s where the pink color comes from makes the wood look kooler during the building process like A beach vibe to keep tempers down during construction phase . It’s a lot of flamingoes but balances things out less people getting hit over the head with 2x4s 😂
We have blue dye in Western Australia
Most pine lumber in my neck of the woods is just kiln dried. We have pressure treated wood but you're not supposed to use it indoors because the chemicals off-gas and having that inside a home is like hotboxing cancer dust. But we make up for it with our wonderful American diet, lol.
We've got that pink lumber here to it's probably some sort of treatment to either last longer or repell bug's!!!
It’s called treated pine and it’s green here in Australia
Better question, why are your studs horizontal?
wow, here in the us we dont have any treatment on interior boards other than the sill plates that touch the ground which would be standard cca (basic pressure treated int/ext. Exterior boards (mostly decks and fence posts) either regular cca, or ground contact cca. Anything more than that would be special order, i've never heard of what those ratings even are or where you would even get them. 28 years in construction.
H1.1 (untreated pine) is not allowed for use in anything other than finishing trims and decorative panels. Been that way for the last 10 years
It’s pink because it comes from the ‘Pink Panther Lumberyard’
Im more interested in the 2x4 exterior walls and all the blocking.
In the US we have brown and green colored treated wood. For reasons. I don't like handling the brown stuff.
I live across the ditch in Western Australia. Our home was started in 1892 and is mostly Jarrah. Some of the massive beams are supposed to be Marri or Karri? I like the construction of your homes which is "similar" to American construction only done properly. Never made it to NZ, my loss.
Probably Kauri?
So , what chemicals are used ? Are they cancerous? How much micro particles are slowly released ?
Copper mostly
Copper Chromium Arsenate complex. Issues with leaching of offcuts and when houses are knocked down. Also use Tributyl Tin Oxides and copper azoles. Not sure which is worse but likely the Arsenic & Chromium if not managed properly which was mentioned and is why it's not used in other countries.
Sorry - many alarmists out there. Don't worry. Once the CCA (NZ wants to phase out) and ACQ (the latter preferred) is locked in the chemicals are generally not reactive and in the wood cells themselves. The valid concern is that copper and/or arsenic overexposure is bad as both cause harm in larger quantities. Those quantity thresholds are nowhere close in approach in finished, treated timber. NZ requires several layers of testing on all treated timbers. Note that CCA does have negative environmental impact issues and NZ is working on getting rid of it. In particular, farming and vineyard posts can leach the chemicals into the ground as the wood degrades - obviously not a goid thing.
The term 'treated' is misapplied often - as the process of treatment includes heating-application-reheating-drying - thus leaching above ground (no ground contact) is generally not an issue.
Also boron is used in the process and it is an inert agent not harmful (but borer and termites hate it).
Short answer: A bunch. Yes. A bunch. You're welcome.
New Zealand is one of the only countries that still uses the chemical mix for external timber, you'll find the states and even Australia has banned it in favour of a safer chemical mix. CCA is banned in the states too.
interesting to know - thanks for watching 👍🏽
Genius.
Is this the same thing as when we make timber green in canada?
Rap music in New Zealand too.
The premise is insane. The world is full of millions of board feet of untreated timber of every species in the interior for hundreds of years that aren't rotting. However, treating to prevent termites is logical and genius.
The comments section is brilliant.
Having watched the video, I still don't know why it is pink. I liked the little pump animation of it shaking whilst pumping the CCA pressure cycles though, thanks. I mixed borax, pyrethrum and antifreeze, just for good measure and doused my rimu 😢floor boards prior to sealing. They didn't turn pink.
It is pink so it is easy to spot when someone uses it in the wrong place. If you see pink timber somewhere exposed to the elements, like under a deck, someone has stuffed up.
Out here building a bloody dock mate
Just local code. We have had Pink preserved. lumber here in the USA for 50+ years.
WoW Your Stick Construction Appears A Lot More Hearty And Sturdy Than American Homes. Is It Because Of The Extra Weight Of Snow and Ice? if the US Added That Extra Use Of Timber That I Can See, It Would Make Our US Homes Cost A Third More! Thats A LOT More Timber Than We Use. Seemingly Anyway. NICE!
Def not a 1/3 more
5:16 ha, i find it kinda neat you could've been on screen the whole time but show up for a split second only
Always wanted to know if the h1.2 KD timber is treated right through the timber like h3.2 ,or just on the surface, watching the video it would suggest the treatment is pumped throughout the timber?
from what I understand it is pumped through in a pressure chamber
@@nzbuilder its a surface treatment really and a compromise between wet boric treated timber that screwed builders backs in the 70's and 80's and kiln dried untreated that rotted in houses in the 90's and early 2000's. Technically you are supposed to treat cut ends though I have never seen that done.
depends how its treated you can get both pressure and dip tanks
What is the average cost per foot (meter ?) to build ?
adds a whole new meaning to havin a pink in the stink
I wish we used macrocarpa as our framing standard.
would you like to pay 4 times what you do for treated pine?
@@codeskhr4092 how did u come to the conclusion it would be 4 times?
