I got/installed a bunch of obsolete laminate flooring off craigslist.
Now, I feel compelled to save some "just in case". Of course, I've
got three different kinds. No chance that I'd
find any compatible stuff in a decade.
I really don't have anyplace to stick it.

The attic has temperature/humidity extremes. And I'd have to
support it between joists.
Garage is FULL!!

I'm thinking about standing the boxes on end along the backside of a
closet. That puts pressure on the ends where they click together.
Also, won't stay there unless it's "tilted" a little. That promotes
warpage. Doesn't do any good to save it if it's not gonna be good
when I need it.

Anybody got experience with storage of extra click-together
laminate flooring?

Thanks, mike

If it's manufactured laminate (instead of real wood), it won't warp,
deflect, swell, rot, get eaten by insects, twist, blow-up, deform, rot, turn
color, expand, contract, de-laminate, scratch, droop, fester, get attacked
by mold, termites, or mice. It is immune to humidity, heat, pressure, wood
rasps, or bullets.

It'll be okay wherever you store it.
