Q: Is there any difference in the stability of 1/2′ versus 3/4′ flooring? We are planning to put hardwood in our dining room and have an existing oak railing. The 1/2′ will fit very well up against the railing, so we are thinking of going with the 1/2′ product for that reason.
A: By stability, do you mean expansion and contraction of the wood itself? Not really. It can be more of an issue with wider planks. However, the 34′ boards offer much more structural stability than the 1/2′ will. You should be fine with the half inch, considering the issue with the railing.
