I like to put some innovation into all my work so I really want to try the composite but I don't think I'll be able to. All the framing is based on lumber 5 1/2" (5 3/4 " gapped) widths, the composite I'd be using (Fiberon) is just 5 3/16" (5 3/8" gapped). That 3/8" gapped difference over 25 - 30 boards screws everything up. 5 1/2" composite is available from a different manufacturer (Trex) but the colors are brutal. The offset design of the deck with one half being 16" deep and the other only 12' deep also complicates the retrofit.
I'll keep trying to come up with a solution for the composite but right now it looks like I'm stuck with cedar.
Here's what it looks like now.
