Q: I have read and been told sand on site maple is more unstable than oak. We are renovating our house which, will have spray foam insulation, and a new furnace with HRV unit. Should we be concerned we installing maple floors? Which is okay re: maple vs oak wood flooring?
A: No, I wouldn’t be concerned. Make sure the flooring is well acclimated before installation and try to avoid very high humidity in summer and very dry conditions in winter. Sounds like you have it covered. But don’t be concerned if you get an occasional little gap here or there. All wood will expand and contract a little. Make sure the floor has an expansion gap along the outside walls.
