I hope thermal treated wood comes to my area. I’ve done some long lasting, interesting things with a blowtorch and some linseed oil, to do that with an oven must have great results. I personally only install wood cladding and hardwood decks. If the client wants plastic or composite they can call someone else.
Very informative as always. I dont think we appreciated how far our Accoia replacement wooden window frames had come when we replaced our original windows a few years ago.Inpart also expplains the price.!
I wonder can you advise… we used larch in a project about 9 months ago & coated it with sioo:x product as discussed in this video. We sealed the end grain of wood with 3 coats & kept larch about 200 mm from ground level. Now however with rain water, the sun bleaching in combo with this sioo:x has turned the larch blackish undertone . despite 3 coats of end grain sealer. In Addition around the windows we placed a metal reveal.. but you can see the moisture climbing up the vertical cladding above the black metal reveal & the larch is getting a blackish stain.. any suggestions why this is happening + how to avoid? There is about a 200 mm void behind the cladding/joists for airflow - any advice recommended.
I don’t think I can advise. From your description everything was done correctly and this should not be happening. Is there anything above the latch, like a roof material, that could be contaminating rainwater which then runs off and reacts with the cladding?
@@fionaholmes-mitra9002 because some people may find a plank covered in knots aesthetically displeasing or unattractive thus making it undesirable. Also, knots have a tendency of falling out as they shrink.
It’s not commonly used for cladding. I’ve heard it can be but the grading must be high and the boards thicker than typical cladding, to ensure longevity.
@@RealLifeArchitecture always thought it was good for external joinery. Good to know. Must just be good for doors and windows that have a finish applied.
Siberian Larch is still available in the UK!!! Pre war stock is available although running out quickly. This Video should be "Titled" Imports of Siberian Larch now Banned!!
Even at the point when I made the video, six months ago, I was being told there were about 2-3 months supply in the country and when it’s gone, it’s gone.
Russwood sell Accoia wood, which has been treated using acid to stabilise it. I didn’t feature it in the video because it is much more expensive and the timber is sourced from New Zealand and Chile, half a world away.
@@RealLifeArchitecture Ah that's a shame to hear the wood is sourced from so far away. It sounds like a promising way to make commodity softwoods into durable cladding, but it seems to have never taken off, probably due to cost it looks like (why buy treated soft pine when you can get larch, etc)

Very nice to hear more about Russwood who I expect I’ll be calling upon for our planned house build on the Outer Hebrides!
I live in the north east of England. I don’t worry about sun fading!😅

Been seeing a lot more thermally modified options coming to the UK over the last couple of years. Some UK grown species like ash and poplar too.
Me too, I’ve seen some up close and it’s a really mixed bag.

It’s great stuff but will probably always be niche

Did You cut a drip angle on the bottom edge ?
Why are knots undesirable?

How about gas and electricity, can we replace it with Scottish larch?
One problem at a time, please
What about Douglas fir?

Nothing beats Iroko period.
what about acetylated wood?
