Best garage door jam trim material?

[TimberMan]

We are on the finishing stages of our new home construction and after several months, the pressure treated 1x8 boards that were used to trim out the masonry / rough opening for the overhead garage doors has dried, warped and cracked and looks bad. What material are most folks using to trim the legs of these openings where the material will run down to the concrete and be placed against the brick / block opening? The masonry openings were accidentally undersized so I am trying to use 1x material and not 2x4 material but if I need to give up some opening for more thickness and a better product please let me know.

Thanks!

Sure it's a regional thing, but around my neck of the woods the Pressure treated wood is usually wrap with aluminum. Personally I would remove the existing warped wood and use kiln dried pt two by material. And not install into the concrete but above.
I also paint all sides before installation. That will help with movement of the lumber. Then if room permits install plastic trim over the wood.

We trim our homes with Boral or Hardie.

We used to use PVC. PVC expands and contracts a lot so it’s not a good choice if you paint it a dark color.

I had pt wrapped with aluminum trim here and it lasted 5 years before the aluminum had holes corroded through from the back.

not surprised, before I wrapped my shed's pt I painted it and used some tywrap type paper that I had laying around. PT is corrosive, plus I like sealing in the poison.

Remember reading about CCA (which is no longer being used) leaching from treated wood into the soil . . . of course they blamed it on the sawdust from building the deck.
It's always installer error, never the product.

It would be white but the board is a 1x8 and it faces west getting direct sun in the afternoons.

White paint on PVC works ok. You can also get PVC in thin sheets (1/4-3/8") so you could rip it and build a think skin overlay on your pressure treat and not loose too much of the opening.

The PVC will move when it heats up. Make sure all joints are properly glued at time of installation and properly nailed (stainless or galvanized).
