ReX Posted August 9, 2020 Share Posted August 9, 2020 Hi, For the new bespoke fences, the landscaper I want to use suggests to use oak but many websites talk about Siberian larch What are the main differences? I am looking for a long lasting solution, requiring reduced maintenance and that doesn't fade or become grey / silver. Thanks Link to comment Share on other sites More sharing options...

I have yet to find a type of timber that doesn't become grey over time. Even the flooring of my balcony which is ipe has slowly become grey although slower than the cedar cladding on the house.

The main difference is durability. The chart below is Trada's guide and is measured using timber posts in contact with the ground. Oak is classified as durable and Siberian larch somewhere between slight & moderate durability. If you keep your fencing at least 150mm off the ground and it's used in an area where its well ventilated it will last a lot longer than indicated in the table.

Where is redwood in the chart? Which wood would be classified as very durable? Link to comment Share on other sites More sharing options...

Untreated redwood is classified as 'slightly durable'. The (untreated) timber species classified as very durable are the tropical hardwoods such as Iroko or Teak. An example of an environmentally friendly treated timber which is very durable is Accoya Link to comment Share on other sites More sharing options...

The timber guys will make all sorts of promises We’ve an oak pork and Iroko gates Both treated with Osmo Both had streaks of grey with in 18 months Quite a bit of work treating it and getting it back to original Link to comment Share on other sites More sharing options...

It’s a tricky one as larch out of the ground in a vented environment lasts really well, but would not last long as a fence post as the bit below ground would rot quickly. It’s also what your supplier gives you as I Have seen a solid oak outdoor staircase rot badly as a lot of the oak used had sap wood in it, oak heart wood is very durable.

By the way I really enjoyed your blog - very informative and cool house! Thanks for the generous comment, glad you found the blog useful. The cedar was untreated and the colour in the picture is after it had stabilised. AFAIK silvering and durability aren't linked. Cedar cladding lasts for around seventy years without treatment and as I said even the ipe decking on my balcony has silvered. Link to comment Share on other sites More sharing options...

We have used Jacksons Fencing in the past and they use a treatment which they guarantee for 25 years against rot. I have used Jacksons trellis at this house and it has been up for two years and has not changed colour at all, compared to the cedar cladding which started silvering before a year was up, and I'm impressed.

We have a lot of oak outside, some treated some not. Untreated oak (eg padock gates) went black before taking many years to go silver with green litchen spots.

ReX Posted August 11, 2020 Author Share Posted August 11, 2020 So, the timber included in the quote is this redwood. I have seen it installed at our neighbors and it looks quite nice. But after 6 months it is difficult to judge how long it will last. So far the color is still as new. Not sure if it has to be stained to avoid color fading or the pressure treatment makes it unnecessary. An alternative that will cost about 4.9 per meter is this one with composite battens. Has anyone experience with composite fences? Link to comment Share on other sites More sharing options...
Adam2 Posted August 12, 2020 Share Posted August 12, 2020 My neighbour has been burning the face of his larch to turn it a dark brown - it's looking quite good but does take some time to do. Apparently then it will not go grey. Will dig up a pic Link to comment Share on other sites More sharing options...

By the way, between redwood and cedar, which one would last longer for fencing? Link to comment Share on other sites More sharing options...
GaryM Posted August 19, 2020 Share Posted August 19, 2020 Untreated Siberian larch will go silver grey, that's one of the major reasons we picked it for our cladding Link to comment Share on other sites More sharing options...
