I think the joints were often tight. Otherwise you got drafts or a breeze. 
Speaking of breezes, we found our plotter ( kept over-heating.) 
Some one kept closing the floor vent.
We eventually found it was the plotter operator who was a young lady with a short skirt.
When loading the mag tape with the plots she had to stand over the vent which blew out cold air,
So she closed the vent.....
... it took some tact to get this info, and we then moved the tile with the vent and the plotter stayed cool...
At another place we had a disk drive drop through a tile. We had had the joiners make some temporary tiles while we were having an upgrade.
The ran out of plywood and joined two scraps, but not very well. The rocking of the drive broke the joint and the drive fell through.
We were surprised it kept working without a head crash....
