I'm redoing my 3 season porch, it sits on top of basement, so it's not like a deck. I think I'll be using the T & G 6" width pine carried by home depot. My concern is how durable it is? The ceiling is insulated, but 3 sides are glass. If I need to use something else, please advise. If pine is ok, would it be cheaper to buy 1x6 pine boards and space it like shiplap? How should I treat it? I plan to stain using ipswitch pine by minwax. Any advice appreciated! Room is 8 x 20. What type of flooring would be best (laminate, wood?) I don't want tile. How do you know what color to use that would look good with white shiplap walls and ipswitch pine stain? My hardwood in my house are red oak. Thank you for any advice you can give!
