Should I choose MDO or PVC?
March 26, 2008
You see the paneling system underneath these three windows? Attractive, right?
But it also looks like it could be a maintenance nightmare if the wrong product was used.
I'd like to replicate this panel system underneath my window by fastening it right to the sheathing. From the research I've done, I can replicate this with either Medium Density Overlay (MDO), MDF's outdoor-safe cousin, or a PVC product like Azek or Fypon.
Seems like MDO is cheaper than PVC, but is harder to find and requires more upkeep.
Anyone have any preference for either?

I've never used either, but from th sounds of it, I'd go with the PVC. MDO is a wood product, and therefore requires similar maintenance to regular wood. It also sounds like it wasn't really designed for long term outdoor use, instead being used mostly for short term signs. PVC is stable, will last forever, and won't require much maintenance.
I've done projects like the one pictured countless times. It's not that tough to do and the results can be stunning. For a panel system like the one pictured here you might consider both products. MDO sheet as your substrate and then create a rail and stile system using PVC trim boards. Once the MDO back is in place, build your rail and style frame (I'd use pocket screws for that assembly) and then fasten the frame over the panel(glue and SS finish screws). You can create a nice detail inside recessed panels using PVC molding or make your own with a router then apply. Many PVC products require a proprietary adhesive, be certain to ask.
Any decent lumberyard can order MDO.
Be sure to properly flash the top of the panel like you would a window, and you'll never regret this project.
One more thing. It wouldn't hurt to use Grace Ice and water over your existing sheathing, then apply the MDO.
PRC lasts and that is what it is all about.
