Never seen real cedar bead board. Do you have a picture of what you are looking for?

Vinyl products are normally a single color, like white, and do not look like real wood.

I saw a similar product at our local lumber yard/home center when we were looking for the vinyl type. It isn't a big box store so I can't suggest you go there.
The stuff does exist, tho.

Do you remember the manufacturer of the cedar looking, but vinyl, bead board?

Sorry I thought that you where looking for bead board that was in the same pattern as you see on cedar ceilings. I would like to say vinyl siding or PVC is not a very good thing to use on your house. If it catches on fire the chemicals it products will kill you be it fast or be it slow. It releases dioxins. Is there a reason you do not want to use Cedar?

I am just as confused as everyone else. I thought you wanted real cedar. Real cedar is what I saw. Do you want the brand? I can check tomorrow

Sorry! Tried to be clear that I want vinyl headboard, but I would like it to look like cedar. Trying to accomplish the real wood look with the low/no maintenance. Haven't found it yet

Is this what you are looking for, only in vinyl?

When you say "looks like real cedar" are you thinking natural cedar, or cedar grain, or what?

Azek brand PVC beadboard might be an option, low maintainance

Jan and ppf (PRO):
I was thinking PVC beadboard. it was just that i wasn't finding a PVC beadboard with the look of cedar grain. I'm seeing it in cedar/brown colors, but not with the "grain" look.

Thanks.....................
