Tongue And Groove Planks Vs. Non-Groove Boards

To minimize bending, contracting, or breaking apart triggered by the nails in the floor joists, almost all timber flooring nowadays uses a tongue and groove flooring technology.

Unfortunately, when walking on the scattered boards with high heel shoes, they aren’t the most practical alternative!
