Q: Can one expect that 3 1/4 oak flooring will be just as stable as 2 1/4 oak flooring? Is there more of a tendency for the wider board to cup over time?
(We have 2 1/4 oak throughout the house and are considering going with 3 1/4 oak in a bedroom.)
A: It is true that wider planks have a greater likelihood of cupping in high humidity conditions. I wouldn’t worry about this with 3 1/4.
