Has anyone used Trex deck boards as trim boards? In particular for rake and soffit trim.
I have been looking at azek trim boards but they are twice the price and would need to be painted. The Trex is already an accepable color.
Any reason I shouldnt use it?
Thanks...Paul
Personally I think it is too ugly. If not supported 16" on a deck it tends to bow. It may also split from what I have seen in the lumber yard , in the back reject pile.
Trex is pretty flexy stuff, and over time would probably sag with gravity and heat/cooling. Keep in mind that it does fade over time as well, so hopefully you'll be ok with that color-wise. I built a deck with it and love it (with about 15" of joist spacing.) No problems with splitting for me. I think the Azek stuff is more stable, ie: less sagging potential.
I would imagine any sagging would be a function of the number of fasteners used, when used as trim. Nobody addressed the weight issue; heavy stuff when having to work up in the air.
Thanks for the feedback, I think I will stick to the Azek.

We used Azek on our house that we finished up this month and it looks pretty decent for "plastic" trim. It is not cheap, true. And the lengths (20') we had to buy them in were difficult to manage.
Azek is not light - although it should be lighter than the Trex decking. The composite decking we installed was quite heavy, so this is a legitimate concern expressed by another poster.
The wider (1x6) channeled boards often look better for trimming out windows and doors. But it all depends on your project of course.
Good luck,
