I installed a 60' long, wrap-around porch using Trex Origins earlier this year.
We really like it! I prefer the Origins version, this is the original, smooth
faced Trex. The Accents version has a molded wood grain that has a harsh
surface, while the Origins is very nice to walk on in bare feet or even socks,
it is smooth but not slippery. I notice that Trex has a high end style called
Brasilia that has a contrasting grain colored like ipe, yet is smooth, not
rough. It is really great looking but I suppose even more expensive. You will
have to go to a real lumber yard to see it, Home Depot does not carry this
Trex is about 1/8" thicker than Veranda, although both manufacturers specify
16" spacing. Trex on a 16" center is very solid. I also used it for my steps
and even resawed boards down to 1/2" to face some parts of the porch framing.
They make 1 x 8 and 1 x 12 boards, but that is thicker than I wanted, and the
trim boards are far more expensive than the deck boards.
Trex and other wood composites can be installed with less end spacing than
all-plastic decks like Eon.
As another poster stated, you will need to trim all ends. They are
simply chopped off at the factory and are not square. Trex allows for this, the
12' boards are over an inch longer to allow for trimming. Trex does not swell
after cutting, routing, etc. I routed all the ends of the steps to match the
factory rounded corners along the length.
I used FastenMaster's TrapEase screws and highly recommend them for an exposed
fastener installation. They are color matched and when you do a nice even
installation they look great. They pull in exactly flush using a deck/drywall
gun. I did have to pre-drill the boards to be able to sink them without the bit
camming out of some screws, even though they are square drive.
