I bought some tongue and groove floorboards. I noticed the tongues and grooves were not centered in the edge but were offset.
┌───────────────────────────────────────────┐ ┌─┘ ┌─┘ └─┐ └─┐ │ │ ← thick side └───────────────────────────────────────────┘
I guess there must be some reason for it. There must be some benefit.
Which way up should I lay these, as shown in diagram or the other way up?
P.S. To make sense of comments & parts of answers that relate to the specific boards I was using - see prior revision.
