Yes :-) (Or something like it)

Two flat outer skins of hardboard separated by a cellular
corrugated-cardboard core.

Oh, that kind of door. Are they still made?

(Cardboard has quite good compression strength
provided it's supported from bending - think of the weight a toilet-roll
core will support on end.)

I know. I use that strength in packing fragile goods.


There was an episode of the Generation Game where the contestants had to
make a door.

er ... Generation Game?
