I am starting a new install, room is 17x13, main floor over plywood. dry living space underneath. 3/4 inch red oak. 3 sides are walls, 4th side is against tile. Customer doesn't want a large expansion gap or raised "Tee" molding at the tile side . Does anyone have experience with expansion gaps on 3 sides only? I understand that most expansion is in the direction of the tongues which I can do away from the tile. Thanks. John
Expansion gaps are generally recommended along the parallel edges of the floor boards as the hardwood will expand in width....minimally to none lengthwise. Expansion is more toward the tongue due to the position of the cleats/staples. Are the tile and hardwood flooring surfaces at the same height?
