This bead board ceiling
is a plastic material but I can't remember the manufacturer who made it.
It came in 20 foot lengths and was easy to install. I installed the
ceiling in about six hours and the material is paintable.
Wood bead board ceilings can expand and contract, over time creating
gaps or buckling in the ceiling. Wood often splits and knots loosen up
to fallout eventually.
I like and prefer the look of wood to anything man-made materials but
this bead board ceiling made from plastic was easy to install and looked
nice when finished.
