Thanks for all of the helpful advice in this forum. Here is my question.

I am building my own cabin in the mountains in Idaho. I've finished the walls and am almost ready to put down the finished floors. I'm doing a combination of tile, carpet and hardwood. Are there any major issues/concerns I should have with putting down a 3/4 white oak tongue and groove unfinished floor (Will be sanding and finishing it myself) as far as temperature variances are concerned? I plan to allow the 3/4" expansion space on the sides by the wall.

In the Winter, I will not be keeping the heat on in the cabin when I am not there, (it would be too expensive) and will be installing the white oak over 1 1/8 OSB subfloor. It can get down to as cold as 0 to -10 in the cabin when the heat is not on.

I would appreciate any thoughts about the above question.
Thanks!

You can expect large gaps in the winter as all the humidity is removed from the environment. Then, in the spring and summer, as temps and humidity rises, many should close up. This floor will move alot because you are not going to keep it at normal living condtions. Under this scernario, I think you are better of with an engineered floor but your call. If you wait to install it when the humidity is low, then it will cup when the humidity returns to normal. Nothing you can do to prevent this, except select a more stable wood or an engineered floor.

Thanks for feedback.

Any suggestions on a more stable wood that has a similar appearance to white oak?

Do they make engineered wood in an unfinished style and is it the same procedure to finish it in place like a solid hardwood floor?

Thanks for the tips and suggestions.

Yes to both questions! However, I'll let you do the research!
