I am curious if there are any reasons not to use a casing molding (typically used for doors or windows) as base molding along the floor? The casing molding is made out of pine which seems to be used for a lot of base molding as well. The casing molding appears to be thicker (11/16" instead of 1/2" or 9/16"). They distinguish them on the sites that sell them, so that's why I ask the question. The casing molding is thicker (which could help with any large flooring gaps left by floating floor) and is a bit cheaper.
