Tongue and groove flooring is designed to be laid directly onto joists, battens over concrete, or even nailed to old timber flooring and provides a tight plank-to-plank fit. Tongue and groove joints on both sides and ends of the plank ensure a continuous and stable surface. The end matching, which is a tongue and groove on the ends of the boards, removes the need for ends to fall directly over a joist or batten. This results in less cutting and less waste.
It is designed to be nailed down and glued. 85mm board widths can be secret-nailed into the tongue while wider boards 130mm and wider are top-nailed for extra stability. Special widths of up to 240mm are available by order.
