I have a customer who is interested in an outdoor tile patio in Brooklyn NY. I have seen alot of problems with outdoor tile in New Jersey. This part of the country has some pretty extreme condition changes. Any body have any input. Also what do you think af incorporating Ipe’ wood borders with the tile am I just asking for trouble.

Few people understand it. Nobody agrees what it is, how to learn about it, or who's responsible for it. It has never been more important

i am of the understanding that porcelain tile would work in that climate due to its inability to absorb moisture. A wood border will expand and contract at a different rate thaan the tile and tile substrait. you would have to plan accordingly and leave a flexible joint in between. there has been alot written regarding the color variations in ipe, so if you are considering, make sure that you can get the ipe that doesn't have the greenish tint that is starting to show up.
good luck.
Just to your north of you Brooklyn project in Westchester County.
Two thing that imediatly come to mind.
Design and plan expansion joints into the project.
Use a crack isolation membrane such as NobleSeal.
The Ipe borders sound like an intersting touch and I don't see any problems with them as long as you plan for the movement in the two disimilar materials.
(and yeah you have to select a tile that is approved or qualifies for use out of doors)

The Tile Council of America has some specs on exterior tile. Get the book and read it.
The most common issue is getting rid of water, especially from the setting bed, so the freeze thaw cycle does not burst the tile. Here are my tips:
1. Gravel base. Lotsa gravel, about 3-4 inches, to take water from the substrate.
2. Concrete Substrate. The Substrate will support the setting bed. The typical application is concrete, which should be pitched to the right or left at a quarter inch per foot.
3. Drainage Mat. Sits on top of the substrate and below the setting bed. The Schulter Co. makes "Troba" an orange plastic mat which facilitates drainage of the setting bed onto the substrate, where pitched, will flow out.
4. Setting Bed. This would be dry pack deck mud, 5-1 sand to portland about 2" thick with reinforcing 3.5 diamond lathe. You might want to pitch this too.
5. Membrane. Yes either the Noble product or anyother type (laticrete 9235) will waterproof the setting bed and reduce, if not eliminate the moisture that may crack it.
6. Porceline (or other low porosity tile). A good dense vitrious tile willl not absorb moisture.
