Does any one have any experience with the new PT lumber? NOT the yellow
PT that was introduced 6~8 years ago.
A few months ago I was considering replacing a door and jam assembly to my
out door storage room, the jam is starting to rot near the sill. Lowe's
offers a door jam guaranteed for life to not rot and it has no chemical to
aid in making it rot and insect proof.
Wood magazine has a short article on the new PT lumber that goes through a
double pressure steam treatment that on the second cycle gets cooked at over
400 degrees F. According to the article the second round in the PT process
makes the sugars and sap unsuitable as food for insects or for rot. All
that is used during this PT process is water and steam.
Have you ever looked at "Plastic Lumber"?
Basically reclaimed HPDE (Plastic milk jugs) with color and filler
Designed specifically for decks, docks and other outdoor wood
Actually I am currently inquiring, however the door jam was something I was
interested in that apparently comes with that product. BUT for future
facia repairs aroung my roof, treated replaces cedar as it goes bad.
I bought a board for my weather station platform.
I figure it would hang in there and so far it has.
Cutting it was a pain in the xxx - remember plastic.
Consider a saw cutting - it cuts nicely, but you have to
pick up the strings of plastic. It won't rot or decay away!
It becomes the pollution issue on that product line.
Simply put a tarp down and cut above it.
I wished they made solid 2x2 or 4x4 but hollow cores are the facts.
What I dislike on it in decks -

First I'm hearing of the stuff, so I did a quick search and came up
Is that the stuff mentioned in Wood magazine? Looks interesting.
First off I indicated PT lumber, I will correct that to Thermally Modified
The site you indicated looks like the same thing. Apparently this type wood
has been available in Europe since the 90's and is only now beginning to be
seen in the USA.
are the references sited by Wood Magazine.
Claims indicate less likely to warp, is more dimensionally stable, and the
wood becomes harder. Predrilling near the ends of boards is recommended to
prevent splitting and the wood will fade to a silvery gray more quickly than
normal when in sun light. Cost right now appears to be about 2x that of PTP
and about the same as Western red cedar.
