Thermally Modified Wood Decking????

deckndave

Has anyone ever used this? I'd like to get some feedback about this product. According to salesman it is free of chemicals, kiln dried (syp?) too so you can stain immediatly after installation. Sample i received looks like treated syp but much lighter and harder. I believe it's about $2.25 +- per LF. Thoughts appreciated!

What has actually been done to the wood to make it better?

Meetre

there was a post last summer about a brand of that stuff, purewood I think. They cook the wood at a higher temp. It is said to "change" the chemical comp. of the wood to make it last longer. Never seen it myself.

Is it this?
http://www.timbersilproducts.com/
Or this?
http://www.purewoodproducts.com/Default.aspx

There have been discussions here
and a good bit of media coverage
but I haven't seen it for sale here.
There was a lot of trouble about getting
the TimberSil approved, but I guess
they finally got past that.
Would like to hear more.

That kind of treatment has been around for a long time. Under that kind of heat the wood is rendered almost inorganic. Under that kind of heat it also is rendered to 1/3 of its strength. J.

There are not any Pure Wood dealers within 500 miles of my location.

I posted about purewood last year and got my lumber yard to become a dealer of the product.

The project I was looking at using it for never happened but the sample is still sitting here next to my desk. It is a nice looking product and if it actually does what they say it does it is definitely an excellent consideration for a mid priced deck material.

A guy came in to show it to us last summer. I dutifully showed it to all my potential customers. No one bit. I haven't bothered with it.

New guy here. Have not used this yet but would be interested in any feed back as well. How it is to work with. The possible need for predrilling every screw hole especially. Would it work well with a hidden fastener? I like the grooved look but would the edges get all banged up? Might work well for some benches for a different look instead of decking that would get bang up.

looks like the pin stripes run at 1" in from the edges...could be a built-in screw guide.
Having all those grooves on the topside means tons of places for water to collect. Not usually a good thing!

Redwood, you're in Northern CA, yes? I haven't heard of the stuff up here either...

Thanks for the replies guys. Neo, it is similar to the purewood except no factory applied finish from what I've gathered so far.

Has anyone installed this and how has it performed?

orson

Mac,

I could be mistaken but if I remember right you can turn it either direction for a different look.

purewood themally modified decking has been around for a while it looks "charred" if you like that kind of thing. there are also processes that bascailly "pickels" the wood with acetic acid that does a similar thing to the wood fibers

I have worked with it. built a walkway at home last summer and am doing a large deck this summer. built a couple of decks last summer for customers. Very happy with it. Should predrill, particularily near the ends, but that is just common sense. Only issue is that it is important to put a UV protector on it, otherwise will grey fairly quickly. The grooves are actually just a style that is common in Europe right now, no other reason. I was told the strength is about 80% of the pre-cooked wood. Nice thing about it is that the wood becomes extremely stable after it has been cooked. Using SYP but virtually no twisting or warping, hard to believe at first but it is true. Are using it for hardwood flooring as the wood does not swell and shrink like regular wood. Water on a deck is not a problem because there is no longer a food source for bacteria so they do not attack it. People I have spoken too generally like it, but for the most part people are leary of a new product. The fact that has been in Europe for about 15 years does not seem to make a difference. Here is a site from Europe with lots of pictures (and no I am not associated with them) swm-wood.com/eng/kuvagalleria.shtml I know there are a lot of locations where you can get it in mid central usa, florida has a few and I beleive colorado, portland oregon and vancouver BC. Is hard to get the product into the lumberyards with everyone trying to cut inventory to survive. Customers need to remember that it is still real wood, so has all the charactoristics, good and bad of real wood.

My local premium supplier now has a product called Cambia, it is a poplar that has been treated with heat as you describe. Also says it will not cup, spli warp or deteriorate!!!!!!! I don't know about this, give me IPE!

MartyCD

The grooves by the way are standard practice in UK and Europe. I don't know how it all got started, but if you buy wood decking on the continent you're going to get those grooves. We've often gotten pressure to do the decking that way for EU market but I agree with the sentiment that it is a place for water to build up and sure to create problems. One thing I've been told is that the grooves were initially added to improve traction. If you search on tanalised wood, which is the UK word for PT, you'll probably find stuff on it.

naturalwood

we actually took a 24" long board 5" by 1.25" decking board and ripped it so we had a piece 24" by 5" by 1/4" to see, and rememer it is SYP. I keep getting laughed at when I say it is flat as a board, but it is. There is no cupping, twisting, etc. Anyone with a sample should try it. Let us know what they find.

John Hyatt

So mabey the troll thing dident fit you Natural,I see you are a Decking Contractor. Just mabey pushing the heat treated thing a little hard...or mabey just sharing info. But implying this materail is the same as Ipe or any S American lumber is a little much.

I would be intersted in pricing in your area. J.

naturalwood

Well it is a thread on Thermally Modified Wood? In our area it is $2.50 a lin ft for true 1.25 * 5
What does IPE run down there.
