Opinions on T1 11 mounted horizontally under covered porch

I would like to install T1 11 horizontally to match my homes vinyl siding l ook. I have read that when mounted vertically the channels wick water. Ha s anyone had experience with it mounted horizontally under a metal roof - i .e. free from direct rain and covered from dew. I live in a humid climate. Thanks for any input

It might depend on which T1-11 you use, 4", 8", 12", as to how well it look s horizontally. *Matching the vinyl siding.... I suppose you'll use the 4" . Prime (pre-paint) a few sheets and temporarily install them, see how it looks, before committing to permanent installation.
I suppose you'll install trim around the edges. Caulk the groove holes, a long the trim, or spiders and other bugs will take up residence in the "hol es". You might want to cram a plug of 3/8" or 1/2" backer rod, into the h ole, before caulking, also. http://www.lowes.com/ProductDisplay?partNumber255-1410-C21&langId=-1 &storeId151&productId465630&catalogId051&cmRelshp=rel&rel =nofollow&cId=PDIO1

It is designed to be installed vertically. The laminate is seen in the routed groove. I would run it the way it was intended.
I could see it wicking water when moist, and being installed in that direction. john

It's amazing how wet things get when they're in a place we think they won't get wet. :-) You have to really paint those channels a few times with a great exterior paint in order for them to not rot out when the stuff is installed vertically/properly. I couldn't see it not rotting after several years when installed horizontally, especially in the lower sections where it will get wet from blown in rain.
If you do decide to go for it, I'd recommend LP SmartSide. http://lpsmartside.com/products/panel It's pre-primed with a very thick, long lasting, anti-fungal application of some kind. I used it on my Sharn and I didn't paint it for probably nine months and it looked like the day I bought it when I did get around to painting it.

I have a problem with it at the bottom of T1 when set correctly. It soaks up water and rots. My shed needs a new bottom. I've been putting it off for 2 years, thinking of putting a 45 degree joint in and slipping a new piece in below the.
So do I think it will wick.. YES. Absolutely.

Jeff, when you install your bottom pieces, bevel (30 degrees is fine) the b ottom edge (bevel on the backside), so that the sharp lip is exterior side. Prime and paint the lower 10" of the backside, also, before installing. This will help prevent wicking up the backside (otherwise raw wood). The sharp bevel front bottom edge will help prevent wicking back, along an oth erwise flat bottom.

says...

Just a suggestion, but if the framing is OK (if it's not pressure treated then it's probably not OK) then cut out the bottom 8 inches or so and put in a PVC board with a z-flashing above.
Be sure to put some blocking at the level of the seam.

I have the same situation, plus the rest is delaminating. I'd like to replace it with barn/roof steel or if they make a PT T1-11. I don't ever want to use regular T1 11 again in my life

T1-11 should never come in contact with the ground. I put it on my shed 25 years ago and it is as good as new. Ground contact requires PT, designed for ground contact, or preferably, concrete or other non-organic, non-rusting material.

From what I've seen T111 isn't a permanent siding solution... Even with maintenance it's got problems in a decade or so around here. An entire condo project near me was resided at about year 5 because of water damage (some of which may have been due to how it was applied... improper/missing flashing, etc.).
Another concern could be that the plys would not be oriented correctly for horizontal application, i.e., the ply strength is designed for vertical application. I have no idea what odd things really could develop out of the non-design application... but my imagination suggests it may wrinkle unless it was nailed with a close pattern. I guess you can tell us in a few years if you go through with this!
