Reason number two: It's dimensionally stable and doesn't warp when the
humidity changes. I like it for stuff that I build for the basement- benches
and etc. But it's not what I'd choose for cabinetry in the living quarters.
It's true that it's more stable and doesn't move with humidity, but
accounting for the movement is quite easy. Also, wide boards should
only get wider with humidity changes, but still remain flat. If they
warp, it's because there were problems with wood preparation or
selection for that part of the piece.
Also, if you choose quarter-sawn boards, then they don't really move
much at all. They're more expensive though.
To me, the durability problems with particle board make it not worth
it. I have two drawers in my kitchen where the fronts have come off
because of being closed too hard while full of silverware. I'm
planning to remake all of the drawer boxes in there so that they hold
together for more than a couple years. A friend of ours gave us a
twin size bed, normal particle board stuff. It didn't even make it
upstairs into the bedroom. I picked it up to carry it upstairs and it
came apart in my hands. The screws that were holding it together blew
out the sides of the boards. I also have a problem with the 1/8" MDF
they use for the backs of furniture, same for drawer bottoms.
Particle board won't hold the staples they use so they start to work
their way out, or they blow out like the bed. That should be at least
1/4" plywood glued in place. I use 3/8" plywood for backs in my
stuff, but I'm considering switching to tongue-in-groove boards so I
don't have to deal with 4/8 plywood sheets anymore.
