What is the recommended expansion space for ¾” solid plank flooring?
Expansion space of ¾” must be left around the perimeter of the room and at all vertical obstructions. More or less spacing may be needed depending on the geographical region, interior climate, and or time of the year. When additional spacing is needed this can be accomplished by inserting thin spacers or washers above the tongue every 10 to 20 rows and then removed after several adjacent rows have been installed and/or start in the center of the room working in two directions.
